FIELD OF THE INVENTION
[001] The invention relates to a horticultural lighting interface for interfacing at least one lighting system. BACKGROUND OF THE INVENTION
[002] Horticulture lighting is known in the art. US2010031562, for example, describes a lighting installation for use in greenhouse farming to illuminate crops in a greenhouse, which comprises a number of light sources, such as lamps, provided above the crops to be illuminated and several switchable devices for the sources of light, characterized by the switchable devices being provided with control means to vary periodically, automatically the light intensity of the light sources that cooperate with the switchable devices according to a predetermined pattern. The document US2010031562 aims to provide a method and installation of lighting, respectively, for greenhouse agriculture. In particular, the light sources are divided into several groups, with the lighting installation being designed so that, during use, the power of each group varies according to a predetermined pattern, while the patterns of different groups have deviations phase with each other, so that the electrical power consumed by the joined groups varies less than the sum of the power variations of the separated groups, more particularly so that the electrical power consumed by the joined groups varies less than the power variation of a group unique, even more particularly, so that the electrical power consumed by the united groups varies to the least possible extent, at least virtually, simply does not. In particular, all patterns are the same, however, only phase shift patterns are related to each other. SUMMARY OF THE INVENTION
[003] Plants use the process of photosynthesis to convert light, CO2 and H2O into carbohydrates (sugars). Such sugars are used to fuel metabolic processes. Excess sugars are used to form biomass. Such biomass formation includes stem elongation, increased leaf area, flowering, fruit formation, etc. The photoreceptor responsible for photosynthesis is chlorophyll and in taller plants, carotenoids are also a part of the antenna pigment. In addition to photosynthesis, photoperiodism, phototropism and photomorphogenesis are also representative physiological processes related to the interaction between light and electromagnetic radiation between 300 nm and 800 nm wavelength and plants:
[004] - Photoperiodism refers to the ability that plants have to perceive and measure the periodicity of Light (for example, to induce flowering),
[005] - Phototropism refers to the growth movement of the plant towards the light and in the opposite direction, and
[006] - Photomorphogenesis refers to the change in shape in response to the quality and quantity of Light.
[007] Two important absorption peaks of chlorophyll a and b are located in the red and blue regions of 625 to 675 nm and from 425 to 475 nm, respectively. In addition, there are also other peaks located in the region of approximately UV (300 to 400 nm) and in the region of distant red (700 to 800 nm). The main photosynthetic activity appears to occur in the 400 to 700 nm wavelength range. The radiation within this range is called photosynthetically active radiation (PAR).
[008] The phytochrome photosystem includes two forms of phytochromes, Pr and Pfr, which have their sensitivity peaks in the red at 660 nm and in the distant red at 730 nm, respectively. Phytochrome activity directs different responses, such as leaf expansion, neighbor perception, shade prevention, stem elongation, seed germination and flowering induction.
[009] In horticulture, light is often quantified in quantity of PAR photons (Active Photosynthetic Radiation) (the contribution to the photosynthesis of all photons between 400 and 700 nm is considered equal) and can be measured and expressed in quantity of photons per second per unit area (in pmol / second / m2; where mol corresponds to 6 «1,023 photons). Alternatively, light can be measured and expressed in terms of optical power (milli) watt.
[010] Plant growth depends, not only on the amount of light or light intensity, but also on the spectral composition, duration and timing of the light on the plant. The combination of ideal light in terms of intensity, spectral composition, duration and timing and depending on the specific plant for plant development in terms of such parameters is called a "light recipe".
[011] Traditionally, only sunlight was available for plant growth. The development of artificial lighting and, for example, greenhouses has led to special lighting devices for such purposes. First, bulb bulbs, lighting devices based on heating wires, were used and high pressure sodium (HPS) lamps. The HPS and the Metal Halide lamps are both gas discharge lamps (the principle is based on the creation of a discharge arc between 2 electrodes in a tube filled with gas that the arc ionizes the gases and halides of metal or, in the case of HPS, sodium amalgam). Only incandescent bulbs (both void and halogen-filled) are based on the principle of a heated wire, mainly of tungsten. A third frequently used principle is the fluorescent tube which is also a gas discharge lamp (filled with mercury vapor) in which the UV light created by the ionized mercury is converted, by means of matches placed inside the glass tube, into visible light. All three types of lamps are used for horticultural lighting. (Often HPS lamps in greenhouses as assimilation lighting create high levels of light; incandescent bulbs as flowering lamps (for inducing blooming) also in greenhouses and fluorescent tubes in chambers of tissue culture growth and plant growth without In principle, LED lighting can and will eventually replace conventional light sources used for horticulture and will probably enable plant cultivation methods that are completely new and cannot yet be predicted. with LEDs, it is now possible to create any spectrum from 300 nm to 800 nm more efficiently than most conventional sources, but it is also possible to control the spectral composition of a Led based on the light source. variety of functions in horticultural lighting, such as:
[012] Supplementary lighting: lighting that supplements natural daylight is used to increase production (of tomatoes, for example), to extend crop production during, for example, the fall, winter and spring periods when culture prices can be higher or as a control method to adjust the culture's morphology.
[013] Photoperiodic lighting: The daily light duration is important for several plants. The light ratio and light period in a 24-hour cycle influences the flowering response of many plants. Manipulating this reason by means of supplementary lighting makes it possible to regulate the flowering time.
[014] Cultivation without daylight in "plant factories" and for tissue culture applications.
[015] In the near future, the conventional light source may continue to play a role. In some situations, they can be less expensive and / or a proven artificial light source for plant growth. Possibly, in combination with natural light sources and / or other artificial light sources.
[016] Several producers of lighting devices provide lighting devices that have different characteristics, in spectral output and / or in spectral intensity. Light sources vary even more with the introduction of LED light sources. In addition, a grower can use and combine different types of lighting devices in his greenhouse. Combining all these different lighting devices in a greenhouse and providing the ideal type of lighting at the right stage of plant growth is a challenge. In reality, LED lighting makes the spectral composition controllable over time. Not only the quantity of the important light, but especially, the quality of the light is of interest and needs to be defined.
[017] For this reason, it is an aspect of the invention to provide a lighting control for application in horticulture and / or an alternative lighting method for application in horticulture, which makes one or more of the disadvantages described above.
[018] The invention thus provides an interface for converting a desired physiological plant response into control instructions for at least one lighting system that has at least adjustable lighting properties, the said interface comprising:
[019] a receiver to receive a desired physiological plant response;
[020] a processor functionally coupled to said receiver to convert said desired physiological plant response into said control instructions, and
[021] a transmitter, functionally coupled to said processor to transmit said control instructions to said at least one lighting system,
[022] in which said desired physiological plant response is defined with a definition point in a multidimensional horticulture action space, in which said multidimensional horticulture action space is represented by at least two dimensions selected from a first dimension representative for a desired photosynthesis action, a second representative dimension for a desired phototropin action, a representative third dimension for a desired Pr phytochrome action and a representative fourth dimension for a desired Pfr phytochrome action,
[023] wherein said processor is functionally coupled to a memory comprising a description of a subspace of the multidimensional horticulture action space representing points in the multidimensional horticulture action space that are convertible into control instructions executable by said at least a lighting system, and
[024] wherein said processor is adapted to map said definition point in relation to a target point in said subspace and to determine corresponding control instructions for said at least one lighting system.
[025] In one embodiment, the invention provides an interface for converting a desired physiological plant response into control instructions for at least one lighting system that has at least one adjustable lighting property, said interface comprising:
[026] a receiver to receive a desired physiological plant response;
[027] a processor functionally coupled to said receiver to convert said desired physiological plant response into said control instructions, and
[028] a transmitter, functionally coupled to said processor to transmit said control instructions to said at least one lighting system.
[029] Said desired physiological plant response is in a modality defined as a definition point in a multidimensional horticulture action space, in which said multidimensional horticulture action space is represented by one among
[030] (i) a first coordinate system comprising at least one representative first dimension for a desired photosynthesis action and a representative second dimension for a desired phototropin action;
[031] (ii) a second coordinate system comprising at least one representative first dimension for a desired photosynthesis action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action; and
[032] (iü) a third coordinate system comprising at least one representative first dimension for a desired phototropin action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action.
[033] Said processor is functionally coupled to a memory comprising a description of a subspace of the multidimensional horticulture action space that represents points in the multidimensional horticulture action space that can be converted into executable control instructions by said at least one lighting system, and said processor is adapted to map said definition point in relation to a target point in said subspace and determine the corresponding control instructions for said at least one lighting system.
[034] Horticulture action space coordinates can, for example, be used in greenhouse control. In greenhouses, many different systems are present that support the growth of culture and other plants. In fact, in this respect, "horticulture" can even be extended to cultivate algae and comparable organisms.
[035] The idea of combining fixed lighting devices with sources of switchable lighting devices and controllable full color light sources in a lighting system and allowing easy spectrum control through the use of horticultural action space is new and it will be beneficial to end users, installers, climate computer builders (programmers) and lamp manufacturers.
[036] The horticultural action space can be used for more purposes:
[037] 1. To predict the plant's response to light and define light recipes for different crops.
[038] 2. To enable lamp manufacturers to characterize the spectral composition of lamp light that is relevant to plant growers.
[039] 3. Additionally, the use of horticultural action space can be found in dynamic spectral control for growth light. Climate control systems can control the light spectrum of the light by communicating the correct coordinates without knowing the light spectrum of the lamps involved.
[040] 4. Light sensors measure the spectrum and can use coordinates to define the spectral composition of both artificial and ambient light.
[041] The known systems that are present in greenhouses are feeding systems, related to the supply of water and / or nutrients, ventilation systems that provide air with the correct temperature and composition, for example, the correct carbon dioxide content and the lighting system to provide the appropriate amount (intensity) and / or composition (spectral) of light in the correct location. In some greenhouses, such systems are controlled by a climate control system.
[042] In known greenhouse systems, growth recipes are provided that allow a grower to select the crop. The growth recipe then provides the climate control system given based on time or it can provide a time schedule and settings for the supply system and the ventilation system. In traditional greenhouses, lighting systems can consist of a passive and an active part. In this regard, the passive part may comprise shading means to alter the natural amount of light, often sunlight. The active part traditionally comprises artificial lighting devices like HPS and incandescent sources. In such traditional greenhouses, the climate control system can activate the shading means and can turn on and off the artificial lighting devices.
[043] In modern lighting systems, more and more LED lighting devices that may have a combination of LED light sources appear on the market. In general, LED light sources have a narrow and well-defined spectral output. In LED lighting devices, a plurality of LED light sources can be combined and even the different types of LED light sources in the direction of spectral output can be combined.
[044] The light output can be defined as a combination of spectral output, the shape of the wavelength versus the intensity curve, and the intensity, the height of such a curve. In some lighting devices, changing one of the spectral output and the intensity can influence the other.
[045] Every lighting device can have different ways of controlling the light output. In a simple situation, like some LED-based lighting devices, LEDs can only be switched on or off. Thus, in such a lighting device, by turning the LEDs on and off more or less, the intensity is gradually controlled. In another light source, such as a light bulb, by turning a light bulb on and off, the intensity is controlled in a binary way. Through the use, for example, of a switching device, the light bulb output is controlled both in intensity and spectral, but not independently.
[046] In a greenhouse in the current situation, a grower, in theory, can thus adjust the lighting conditions in his greenhouse in all directions. In practice, however, in order to be able to control light conditions to affect plant development, for example, software on a climate computer will need to have very detailed technical information about the lighting devices installed, as well as their position in the greenhouse. in order to control the spectral composition and light intensity and, eventually, the light received by the plants. Today, with conventional lighting, growers cannot actually control the spectral composition of light. Only the light level can be controlled. With LED lighting or a combination of LED lighting and conventional lighting, the spectral composition can be controlled, for example, via the climate control computer. For that, detailed information about the installed lighting devices, as well as their position in the greenhouse, must be available to the climate computer in order to create the correct light levels and spectral composition of the light at the plant level. In addition, the results of research institutes that provide ideal lighting conditions should be translated into definitions that are within the capabilities of the available lighting system.
[047] A current development is to produce light recipes that can be used, for example, in climate computers and light control devices for lighting devices. In addition to light control devices, light sensors can also be used to measure one or more of ambient light levels (intensity and / or spectral composition) and light levels of artificial lighting devices in a greenhouse.
[048] Communication between all these components is complex and now depends on individual devices.
[049] The development of the horticultural action space allows controls to become less dependent on the technical construction of lighting devices and other components. Another advantage is that, with the definition of the horticultural action space, only the correct coordinates need to be calculated and generated. The same coordinates can be generated by different lighting devices and using different spectra. Now, the most effective way to generate a requested lighting condition and / or desired light condition can be used. This can be both energy efficiency, cost effectiveness and even based on ergonomic demands. In some situations, a human can judge the situation of the crop or plants. The effect on the plant, however, would be the same.
[050] The horticultural action space can be used to predict the plant's response to light and define light recipes for different crops. The horticultural action space, on the other hand, can enable lamp manufacturers to characterize the spectral composition of the lighting device output in a way that is relevant and understandable to plant growers. It can also provide a clear and transparent way of communicating the effect of the lamp or the quality of the lamp to growers. In addition, the use of horticultural action space can be found in dynamic spectral control for growth light. Climate control systems can control the light spectrum of lighting devices by communicating the correct coordinates without detailed knowledge of the exact light spectrum of the lamps involved. The light sensors can measure the resulting spectrum and can communicate the results in the form of coordinates in the horticultural action space.
[051] In this way, only the coordinate control area of a plant light recipe should be implemented in the control software and can be used as long as the lamps can be operated in the desired color area. Lamp-dependent reprogramming is simplified. The lamp driver architecture may no longer be relevant to the control software. The light recipe does not need to be embedded in the lighting device, but it can be sold to the end user with additional software for the climate control software. Alternatively, the light recipes can be provided in a remote database that can be accessed, for example, through the interface.
[052] A feature of the horticultural action space is that the spectral composition of light that is offered to a plant can be expressed in relevant plant units. Such units are derived from plant absorption and response / action characteristics. The spectral composition of light is translated into the horticulture action space at one point or coordinated in the horticulture action space. This point is additionally communicated and translated into light intensity and spectral composition for the installed lighting systems. In this way, it can simplify communication between growers, plant physiologists, biologists, greenhouse developers and greenhouse climate control systems and lamp manufacturers.
[053] In plant physiology studies, it has been found that various parts of the light spectrum are responsible for various aspects of plant development. Over the years, this has led to the definition of several so-called action spectra. Such action spectra represent the relative contribution of a spectral component and its relative effect on plant development. In other words, they define the relative effectiveness of different wavelengths of light to induce a biological response. Such action spectra also refer to the presence of photosensitive components in plants, such as chlorophyll.
[054] One of the action spectra that is well defined in the literature is the McCree action spectrum. Such an action spectrum allows to relate the amount of photosynthesis in a medium plant to the light conditions. It is based on the photosynthetic activity of an average plant. Its validity is, for example, recently confirmed in E. Paradiso et al., Spectral dependence of photosynthesis and light absorptance in single leaves and canopy in rose, Science Horticulturae 127 (2011), pages 548 to 554. McCree's curve was first identified by McCree in 1972 and was validated in that publication.
[055] In other studies, the effect called phototropism is identified. This effect is induced by so-called phototropins, blue light receptors in plants, which induce, in addition to phototropism, for example, chloroplast migration and stomata opening induced by blue light. It is responsible, for example, for the movement of plant growth towards light and in the opposite direction to it. This is, for example, described in Winslow R. Briggs and John M. Christie, Phototropins 1 and 2: versatile plant blue-light receptors, Trends in planta Science, volume 7 no. 5, May 2002, pages 204 to 210.
[056] In other studies, two interconvertible forms of phytochromes have been identified. They are also called action spectra Pr and Pfr. The importance of phytochromes can be assessed by the different physiological responses in which they are involved, such as leaf expansion, neighbor perception, shade prevention, stem elongation, seed germination and flowering induction. The two important spectra of action in this regard are a form of absorption of Red-distant phytochromes (Pfr) and a form of absorption of Red phytochromes (Pr). The relevant action spectra and phytochrome photoequilibrium calculation are, for example, identified in JC Sager et al., Photosynthetic Efficiency and Phytochrome Photoequilibria Determination Using Spectral Data, American Society of Agricultural Engineers 0001-2351 / 88/3106, pages 1,882 to 1,889.
[057] Such action spectra explained and discussed above have been combined in the horticulture action space that is used in this document. For most green plants, such action spectra can be used. For other plants, including algae, other spectra of action may be needed. Such specific action spectra can be used in the same way as the action spectra identified above.
[058] It has been found that the use of two dimensions already allows a description of lighting conditions that can be used in cases where a limited amount of and / or a limited type of lighting devices are used. It was found that in this case, these two coordinates provide the best description. However, it may be necessary to use a more detailed definition of horticultural action space.
[059] The coordinates of horticulture action in one modality represent at least one amount of photosynthesis action and one amount of phototropin action. A definition for calculating such a quantity is to incorporate all contributions to the specific action for all relevant wavelengths of light, considering the contribution to be heavy. In this respect, the appropriate weight depends on the intensity of the light at a given wavelength that is considered. One way to calculate the amount of action is to take the amount of action relative to each relevant wavelength and adding these relative amounts for all relevant wavelengths.
[060] It is clear that there are, therefore, different ways of calculating a horticultural action space that can be used in horticultural applications.
[061] In the present invention, several steps have been taken in order to reach a horticultural action space that allows communication regarding lighting conditions and that is as independent as possible of the exact spectral properties of the lighting devices that are present in a greenhouse. An advantage of the definition below is that it allows a definition that is clear: it provides a space that is as linear as possible and allows the calculation of several other quantities that can be used in plant / biological processes.
[062] Below, an example of a horticultural action space based on the principles explained above is elucidated in detail. Other useful horticultural action spaces may be possible. It was found, however, that the definition below provides a space that is as linear as possible, provides insight to all parties involved and is relatively easy to understand and use in practice. Such a horticultural action space can be used for most known green plants.
[063] A four-dimensional horticultural action space can be defined as follows. First, the following values are defined:


[064] In such equations, I (À) is defined as the radiant flow in Watt. In order to use such values, the action spectra explained above are normalized. In Figure 5, which will be explained in more detail below, the normalized action spectra are plotted. Each action spectrum is actually normalized so that its maximum value is 1. For the action spectrum Pfr (À), the normalization of the action spectrum Pr (À) is used due to the fact that these action spectra in practice, they are interrelated. The W, X, Y, Z values are then normalized in a normalized four-dimensional space:

[065] An advantage of such a definition of the horticultural action space is that the calculations are simplified, the communication of the plant action becomes significant as the space becomes normalized. Such normalized coordinates, however, also require that an indication of absolute light intensity is also communicated. A simpler way is to communicate the integral of I (À) along the relevant wavelengths, "I", together with the coordinates. A more elegant way is to communicate one of the coordinates of horticultural action space in its absolute value. In the communication of horticultural action space coordinates, the Y value is an absolute measure of the amount of photosynthesis. In one embodiment, the Y is therefore communicated as one of the coordinates. In one embodiment, Y is used in conjunction with x. Alternatively, Y is used in conjunction with x and y.
[066] In an alternative modality, (z, x, w) or (x, y, w) are used as a minimum set. Again, one of such coordinates can be used in its absolute value ("capital") or, if not present, Y can be added.
[067] One way of pointing out the exact horticulture action coordinate is to use the coordinate (W, X, Y, Z). In order to more easily compare the quality of light sources of light, (x, y, z) is relevant and it is observed that w = 1 - x - y - z. A complete coordinate definition can be (x, y, z, Y), due to the fact that from such a definition (or space) the coordinate (W, X, Y, Z) can be calculated: W = w * (W + X + Y + Z) = w * (Y / y) X = x * (Y / y) Z = z * (Y / y)
[068] In particular, in a four-dimensional space, the quality of light can be expressed in the coordinate (x, y, z) in 3-D and the amount of light in the value of Y. Again, such a definition (x, y, z) must have an indication of light intensity in order to perform calculations regarding light systems. Again, "I" can be added, Y can be added or used instead of y, or one or more of the other coordinates can be used in its absolute form ("capital").
[069] From the coordinates of the horticultural action space, various quantities can be calculated, in which they are directly related to the plant action. In such a calculation, the total light intensity already mentioned, "I", defined as radiant flux (again, in Watt) is used:

[070] Relative photosynthetic activity = Y / I
[071] Relative phototropin response = Z / I
[072] In this respect, PSS is also defined as Pr / (Pr + Pfr). In the communication and definition of the horticultural action space, as explained, it was found that the total amount of optical energy is an important parameter. The explanation above shows that, instead of communicating "I", it provides more insight into the nature of the coordinates if "Y" is used.
[073] In current calculations, coordinates are calculated using an optical wavelength range of 300 to 800 nm. It may be possible to expand such a range to a wider wavelength range if necessary. For example, there may be plants or algae that show activity in other bands or in broader wavelength bands.
[074] In one embodiment, the processor is adapted to design or map said definition point in said subspace based on at least one optimization criterion. Such an optimization criterion can, for example, be the amount of energy used by the lighting system or the complete lighting system of a greenhouse, for example. Alternatively, a grower may have preferences regarding the use of certain lighting systems or light sources in the lighting system.
[075] In one embodiment, the multidimensional horticulture action space comprises at least one representative first dimension for a desired photosynthesis action, a second representative dimension for a desired phototropin action, a third representative dimension for a desired Pr phytochrome action and a representative fourth dimension for a desired Pfr phytochrome action.
[076] It was found that these four dimensions, together, can predict the development of the plant for a large part. The exact calculations for such dimensions have already been explained above.
[077] In one modality, the multidimensional horticulture action space comprises an additional dimension, in which said additional representative dimension for a desired stoma opening action. The opening of stomata and a possible spectrum of action are described, for example, in Silvia Frechilla et al., "Reversal of Blue Light-Stimulated Stomatai Opening by Green Light", Plant Cell Physiol. 41 (2): 171 to 176 (2000). This additional dimension can be defined in a similar way to the other dimensions explained above.
[078] In one embodiment, the receiver is additionally adapted to receive a horticultural light recipe that comprises at least one marker to identify a type of plant, at least a desired physiological plant response and a time schedule for said at least one desired physiological plant response, said at least one desired physiological plant response being represented as at least one horticultural action coordinate. The horticulture light recipe can thus comprise a time schedule with several coordinates of horticulture action corresponding to the time schedule. In this way, the development of the plant can be controlled and directed. Multiple light recipes can be provided in a database that can be remote from the interface. It can be accessed through the interface through a network, for example, through the internet.
[079] In one embodiment, said receiver is additionally adapted to receive a lighting system definition that comprises a lighting system identification with associated control instructions to execute physiological plant responses defined as points that define said subspace in said multidimensional horticulture action space and in which such control instructions are executable through said at least one lighting system, and said receiver is adapted to provide said definition of lighting system for said memory. In one embodiment, multiple lighting system definitions can be provided in a lighting database. Again, such a lighting database can be remote from the interface. It can be accessed through the interface through a network, for example, through the internet. Such a set of lighting system definitions allows for smooth switching between lighting systems. It allows the combination of several lighting systems. Such lighting systems can be complementary or supplementary. This can allow for a quick selection of lighting systems that need to be used in order to have a defined plant development.
[080] In one embodiment, the receiver is additionally adapted to receive a representative sensor value for a detected light spectrum and in which the processor is additionally adapted to map said sensor value in relation to a detected point in said detection space. multidimensional horticulture action. In such a way, it is possible to integrate the real lighting conditions. This can provide, for example, feedback to control at least one lighting system.
[081] In one embodiment, the interface that also comprises a display, functionally coupled to said processor, to display the subspace of said at least one light system related to the horticultural action space or to display projections thereof, in accordance with preferably, the display additionally displays at least one of said definition point and said target point in relation to said subspace, of projections thereof. Such a display can, for example, provide feedback to a user, for example, a grower in a greenhouse. The display can, for example, be integrated into a portable device and thus provide feedback to a grower during his work, for example, in a greenhouse. By, for example, combining the display with the previously mentioned sensor values and allowing the display to also include said detected point, a cultivator can compare the desired settings and the resulting effect visually and instantly. The display can be a visual computer screen, for example, an LCD or OLED screen. It can be equipped with a so-called touch interface.
[082] The invention additionally relates to a horticulture system, which comprises a horticulture lighting interface described above, at least one lighting system and a climate control system. In such a horticulture system, the interface is functionally coupled to a climate control system to provide at least one desired physiological plant response to said interface and additionally functionally coupled to a lighting system to receive control instructions from said interface and to provide light mapped to said at least one desired physiological plant response. The interface can be physically separate and even remote from at least one of the climate control systems and at least one lighting system. In such embodiments, data transfer can be carried out in a known manner, for example, wirelessly. In such an embodiment, the interface can be a separate unit, even supplied in a separate housing. Alternatively, the interface can be incorporated in at least one of the climate control system and the lighting system. In such a modality, the interface can even be a software element or a complement that is executed by the climate control system and is, therefore, added or incorporated in a software executed by the climate control system. It can also be executed by the lighting system and / or it can be integrated with the software that is executed by the lighting system.
[083] The invention also relates to a horticulture system comprising the horticulture lighting interface described above and a horticulture light recipe management system. The horticulture light management system is adapted to provide a horticulture light recipe that comprises at least one marker to identify a type of plant, at least one desired physiological plant response defined as at least one point of definition in said space of multidimensional horticulture action, a time schedule for said at least one desired physiological plant response, in which said interface is functionally coupled to said horticulture light recipe management system to receive said horticultural light recipe . The light recipe management system can be remote from the interface and even remote from, for example, the physical location of a greenhouse using the horticulture system. The same can be accessible via a network, for example, via the internet. The interface and the light recipe management system can exchange information, such as one or more light recipes, and the interface subsequently provides the resulting lighting system control instructions for one or more lighting systems.
[084] The invention also relates to a horticulture system that comprises the horticulture lighting interface described above, in order to further understand a lighting management system that comprises a repository of lighting system definitions , in which each one comprises a lighting system identification with associated control instructions to execute physiological plant responses defined as points that define said subspace in said multidimensional horticulture action space and in which said interface is functionally coupled to said lighting management system to access said repository. The interface and lighting management system can be remote from each other. The lighting management system may even be remote from, for example, a greenhouse using the horticulture system. The lighting management system can be coupled to the interface via a network, for example, via the internet. The interface and lighting management system can exchange information, such as one or more lighting system definitions, and the interface subsequently provides resulting lighting system control instructions for one or more lighting systems. It is possible, for example, to select one or more of the available lighting systems that can be installed in a greenhouse and that need to be used.
[085] The invention additionally relates to a sensor to provide a representative sensor value for a detected light spectrum, wherein said sensor is functionally coupled to a sensor interface to convert said sensor value into a estimated physiological plant response, wherein said sensor interface comprises:
[086] a receiver for receiving a sensor value;
[087] a processor functionally coupled to said receiver to convert said sensor value to said estimated physiological plant response, and
[088] a transmitter, functionally coupled to said processor to transmit said estimated physiological plant response.
[089] Said estimated physiological plant response is defined as an estimation point in a multidimensional horticulture action space, in which said multidimensional horticulture action space is represented by one among
[090] (i) a first coordinate system comprising at least one representative first dimension for a desired photosynthesis action and a second representative dimension for a desired phototropin action;
[091] (ii) a second coordinate system comprising at least one representative first dimension for a desired photosynthesis action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action; and
[092] (iü) a third coordinate system comprising at least one representative first dimension for a desired phototropin action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action.
[093] Said processor is adapted to map said sensor value in relation to said estimation point. The sensor is easily integrated into a horticulture system using the horticultural action space. In one embodiment, the sensor values are given by spectral measurements. In such an embodiment, spectral data can be provided at regular wavelength intervals. For example, values can be provided every 10 nm or every 20 nm. In the horticulture application mode, sensor values can be provided for a wavelength range of 300 to 800 nm. The sensor can be equipped with a dispersive element and a spatial detector, for example, a CCD strip detector or a 2D CCD sensor. Alternatively, a sensor can be equipped with several filters in one or more detectors. This, in fact, is known to one skilled in the art. Sensor values, in fact, can directly provide the values of I (À) that are used to calculate X, Y, Z, W as explained above, or they can provide sensor values from which I (À) can be derivative.
[094] The invention further relates to a method for converting a desired physiological plant response into control instructions for at least one lighting system that has at least one adjustable lighting property, wherein said method comprises:
[095] receiving a desired physiological plant response, in which said desired physiological plant response is defined as a definition point in a multidimensional horticulture action space, in which said multidimensional horticulture action space is represented by a among
[096] (i) a first coordinate system comprising at least one representative first dimension for a desired photosynthesis action and a second representative dimension for a desired phototropin action;
[097] (ii) a second coordinate system comprising at least one representative first dimension for a desired photosynthesis action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action; and
[098] (iii) a third coordinate system comprising at least one representative first dimension for a desired phototropin action, a second representative dimension for a desired Pr phytochrome action and a third representative dimension for a desired Pfr phytochrome action;
[099] converting said desired physiological plant response into control instructions, the conversion comprising mapping said definition point to a target point in a subspace of the multidimensional horticultural action space and determining corresponding control instructions for said at least one lighting system, wherein said subspace comprises points in the multidimensional horticultural action space that are convertible into control instructions for said at least one lighting system and executable through said at least one lighting system ; and
[0100] transmit said control instructions to said at least one lighting system.
[0101] In the present description, lighting systems comprise lighting devices that can be adaptable in intensity, emission spectrum or both. Currently, for example, LED-based lighting devices are marketed.
[0102] The LEDs can be solid state LEDs, but they can also optionally be organic LEDs. In addition, combinations of solid-state LEDs and organic LEDs can be applied. In reality, this application provides a solution for any type of lighting device. The term "LED '' 'can also refer to a plurality of LEDs. For this reason, in one embodiment, in a single LED position, a plurality of LEDs can be arranged, such as a set of 2 LEDs. or more LEDs. LEDs are specifically designed to generate light (LED) of the first wavelength range.
[0103] The emergence of solid state lighting based on LEDs offers opportunities for application in horticulture. The main advantages of using LEDs result from the possibility of controlling the spectral composition of the light to be approximately compatible with the photoreceptors of the plant. In addition to the additional benefits such as improved heat control and the freedom of distribution of the LEDs, this provides a more ideal production and allows the influence of the plant's morphology and composition. Their use also promises reduced energy consumption (and associated cost).
[0104] Due to the fact that they are solid state devices, solid state LEDs are easily integrated into digital control systems, in order to facilitate lighting programs, such as simulations of "full daylight" lighting and the sunrise and sunset. LEDs are safer to operate than today's lamps due to the fact that they do not have glass envelopes and do not contain mercury.
[0105] LEDs enable the distribution of light closer to the target, which can result in less loss across the roof and the greenhouse floor. In addition, better light distribution in the crop can be achieved. This is certainly the case for suspended wire crops such as tomatoes.
[0106] In the interface, the receiver and the transmitter can be implemented by software, or they can be implemented by hardware. The processor can be a general purpose microprocessor that executes machine instructions. The memory can be any type of memory, for example, digital memory that can be functionally coupled to the general purpose microprocessor. The known memory media are RAM, ROM, flash memory, hard drives and the like. Such types of memory can be physically connected to the interface and, in fact, to the processor. Alternatively, the memory is connected wirelessly, it can even be remote from the processor and accessible through a network or the internet, for example.
[0107] The control instructions for the lighting system can be simple on / off instructions. In more advanced lighting systems, they can be instructions that define an output level, for example, 0%, 50%, 100%. Such definitions can even be continuous, between 0 and 100, for example. In even more advanced systems, using, for example, different types of LED sources, the control instructions can define which sources should be turned on and off and even the power output of each source can be defined. In an even more advanced source, the spectral output can even be defined.
[0108] At the interface, the subspace of the multidimensional horticultural action space is a description of the points that can be made viable with the use of at least one lighting system. In mapping, the definition point can simply be a point in the subspace. And even so, it may be valid not to provide the control instructions that, in fact, generate such an exact definition point, but to find a related target point that is within a defined range of the definition point but that meets the criteria such as, for example, example, energy consumption of the lighting system by means of such control instructions or other criteria, such as production of additional heat, use of available light sources, in particular, an ideal use of natural light sources.
[0109] In case the definition point is outside subspace, an approximation can be calculated. This can be done in several ways and using several optimization criteria. For example, a point closest to the subspace that is closest to the definition point can be selected first. Subsequently, the optimization illustrated above can be performed.
[0110] The terms "upstream" and "downstream" refer to an arrangement of items or resources related to the propagation of light from a means of generating light (in this document, specifically the first source of light), in which is related to a first position within a light beam from the light generating medium, a second position in the light beam closest to the light generating medium is "upstream" and a third position within the light beam light further away from the light-generating medium is "downstream".
[0111] As indicated above, the invention also provides a method for providing growth light in horticultural applications which comprise providing at least a part of the culture with horticultural light from the lighting device according to any one of the claims. previous ones. Specifically, the method may comprise varying the spectral intensity distribution of the horticultural light as a function of one or more of (a) the mentioned part of the plant or crop, (b) the time of day, (c) the light intensity and the light distribution of light other than Artificial light, (d) the type of crop or plant cultivar (e) the growth stage of the plant or crop, (f) the stage of a horticultural crop, (g) the time to harvest, (h) the time since harvest and (i) the position in the horticultural layout.
[0112] Horticulture refers to the (intensive) plant cultivation for human use. When illuminating horticulture, the term "horticulture" can refer to the cultivation of plant production for food crops (fruits, vegetables, mushrooms, culinary herbs) and non-food crops (flowers, trees and shrubs, grass grass, hops, grapes , medicinal herbs or food crops). The term horticulture can refer specifically to food crops (tomatoes, peppers, cucumber and lettuce), as well as to plants that (potentially) bear such crops, such as a tomato plant, a pepper plant, a cucumber plant , etc. Horticulture can, in this document, refer in general to, for example, crop plants and non-crop plants. Examples of culture are Rice, Wheat, Barley, Oats, Chickpeas, Pea, Cowpea, Lentils, Chinese beans (vigna radiata), Indian beans (Vigna mungo), Soy beans, Common beans, Moth beans (Vigna aconitifolia), Flaxseed, Sesame, Chicharo, Sana, Peppers, Eggplant, Tomato, Cucumber, Okra, Peanuts, Potato, Corn, Pearl millet, Rye, Alfalfa, Radish, Cabbage, lettuce, pepper, Sunflower, Sugar beet , Ricino, Red carnation, White carnation, Safflower, Spinach, Onion, Garlic, Turnip, Pumpkin, Musk melon, Watermelon, Cucumber, Pumpkin, Quenafe, Oil palm, Carrot, Coconut, Papaya, Sugar cane, Coffee, Cocoa, Tea, Apple, Pears, Peaches, Cherries, Grapes, Almond, Strawberries, Pineapple, Banana, Cashew, Irish, Cassava, Cara, Rubber, Sorghum, Cotton, Triticale, Guandu and Tobacco. Those of greatest interest are tomatoes, cucumbers, pepper, lettuce, watermelon, papaya, apples, pears, peaches, cherries, grapes and strawberries.
[0113] Horticulture can take place in a greenhouse. The interface can be used specifically in relation to the application of the interface and / or the method in a greenhouse. When used in or with lighting systems, such lighting systems may be arranged at different locations in a growth system. For example, the lighting system can be arranged between the culture or between the future culture, and this arrangement is indicated with "inter-illumination". The growth of horticulture in wires, like tomato plants, can be a specific field of interlighting that can be mentioned with a lighting system. The lighting system can also be arranged on the culture or future culture. Especially when horticulture is grown in layers on top of each other, artificial lighting is necessary. Growing layered horticulture is referred to as "multilayer growth". In addition, in multi-layer growth, the interface and / or method can be applied.
[0114] The invention provides a new way to control artificial lighting used to stimulate plant growth and development, a technique that is known as horticultural lighting. In particular, there are two main horticultural environments in which artificial lighting is used. First, greenhouses increase crop yields with the use of overhead lighting and intradossel lighting in addition to daylight. Second, and in multilayer systems, crops grow mainly without daylight and thus depend significantly on artificial lighting. In addition, the invention relates to photoperiodic lighting, for example, to control flowering.
[0115] The term "substantially" used in this application, such as "substantially all light" or "consists substantially", will be understood by the person skilled in the art. The term "substantially" may also include modalities such as "totally", "completely", "all", etc. For this reason, in modalities, the adjective can also be substantially removed. Where applicable, the term "substantially" may also refer to 90% or more, such as 95% or more, specifically, 99% or more, even specifically, 99.5% or greater, including 100%. The term "comprises" also includes modalities in which the term "comprises" means "consists of".
[0116] Furthermore, the terms first, second, third and similar in the description and in the claims, are used to distinguish between similar elements and not necessarily to describe a sequential or chronological order. It should be understood that the terms thus used are interchangeable under the appropriate circumstances and that the modalities of the invention described in this document have the capability for operation in sequences other than those described or illustrated in this document.
[0117] The devices in this document are, among others, described during operation. As will be clear to the person skilled in the art, the invention is not limited to methods of operation or devices in operation.
[0118] It should be noted that the mentioned modalities illustrate, rather than limit, the invention, and those skilled in the art will be able to design any alternative modalities without departing from the scope of the attached claims. In claims, any reference signs placed in parentheses should not be considered limiting the claim. The use of the verb "to understand" and its conjugations do not exclude the presence of elements or steps beyond those mentioned in a claim. The article "one" or "one", before an element, does not exclude the presence of a plurality of such elements. The invention can be implemented by means of hardware that comprises several distinct elements, and by means of an appropriately programmed computer. In the device claim enumerating various means, several of such means may be incorporated by one and only one item of hardware. The mere fact that certain measures are referred to in mutually different dependent claims does not indicate that a combination of such measures cannot be used to advantage.

[0128] Drawings are not necessarily to scale. DETAILED DESCRIPTION OF THE MODALITIES
[0129] Figure 1 shows schematically an example of a greenhouse 1 with several systems. Such a greenhouse 1 is, for example, described in US 8.061.080 of the present applicant. It shows a greenhouse 1 of the prior art. Such greenhouse 1 comprises a climate system. In this modality, the climatic system comprises a feeding system 2 to supply water and nutrients, a ventilation system 3 to supply air, being that it has the correct composition (carbon dioxide content, for example) and at the correct temperature. In addition, the climate system of such a greenhouse comprises a lighting system 4,5. In the embodiment of Figure 1, the components of the climate system, that is, the supply system 2, the ventilation system 3 and the lighting system 4, 5, are wirelessly coupled, via transmitters 7, to transmitter 8 of a climate control system 9. In this mode, the stove additionally comprises sensors 6, for example, to determine lighting conditions, temperature, humidity. Such sensors are also wirelessly coupled, via transmitters 7, to the climate control system 9. In such a greenhouse, plants 11 are located on a substrate 10.
[0130] In the embodiment of Figure 1, the lighting system 4, 5 comprises an active lighting system 4 which comprises, for example, lighting devices such as traditional incandescent lighting devices, but may also include LED lighting devices . The lighting system 4, 5 additionally comprises, in this embodiment, passive lighting devices 5, in this document, the shading means to reduce the amount of sunlight entering.
[0131] Figure 2 schematically shows an example of plants 11 in a greenhouse with different types of lighting devices 4, 12 that may be present. In such a way, such lighting devices are known to a person skilled in the art. First, the stove may be equipped with one or more traditional lighting devices 4. Such traditional lighting devices may comprise an incandescent-based lighting device 4. This type of lighting device may come from several manufacturers. Depending on the manufacturer, even the same type of lighting device can vary in emission spectrum. In addition, a lighting device ages, which can also change its emission spectrum.
[0132] In addition, lighting devices located 12 as LED lighting devices 12 may be present in a greenhouse, which varies with respect to lighting devices that provide local lighting and lighting devices that provide general lighting. With LED lighting devices 12, the emission spectra can vary and / or the total light intensity can be varied even more than with traditional lighting devices.
[0133] In addition, the lighting system can comprise one or more shading devices 5, shown in Figure 1. This can also be considered as a control device for a particular lighting device, namely a natural lighting device, the sun .
[0134] Combining all of these lighting devices (and, in fact, including the shading device) each with its own emission and intensity spectrum it becomes complex for a grower to provide the right light conditions for his culture at the right time.
[0135] In the present invention, several steps were taken in order to reach a horticultural action space that allows communication regarding lighting conditions and that is as independent as possible of the exact spectral properties of the lighting devices that are present in a greenhouse.
[0136] As already explained, the four-dimensional space can be defined as follows. First, the following values are defined:

[0137] For the use of such values, the action spectra explained above are first normalized. In Figure 3, normalized action spectra are plotted. Each action spectrum is actually normalized so that its maximum value is 1. For the action spectrum Pfr (À), the normalization of the action spectrum Pr (À) is used due to the fact that these action spectra in practice, they are interrelated. The W, X, Y, Z values are then normalized in a normalized four-dimensional space:

[0138] In the communication of horticultural action space coordinates, the value of Y is communicated together with x, y as a minimum set, or (w, x, y, z and Y) as a complete set. From the coordinates of the horticultural action space, various quantities can be calculated, in which they are directly related to the plant action. In this calculation, the total light intensity is used:

[0139] Relative photosynthetic activity = Y / l
[0140] Relative phototropin response = Z / l
[0141] First, Figures 4 to 6 are provided in order to give plant physiologists more insight into the nature of the horticultural action space. In such plots or graphs, several light sources are plotted. The geometric axes are chosen by people versed in the field so that they can evaluate possible dimensions of space of action against their knowledge. For example, the PSS value is plotted. Such PSS value is calculated as defined above. In addition, a parameter indicated with "McCree" is plotted. This, in fact, is the value of Y, but normalized to 1. This value thus provides a relative measure for the amount of photosynthesis. A "Phototropin" parameter is also plotted. This value, in fact, is the value of Z defined above, again normalized to 1. In addition, small points are plotted, which are indicated as "transfer". These points represent the values of virtual, monochromatic light sources, with a rectangular spectrum with a width of 1 nm. In the graphs, the limits show the physically possible light sources. In this way, the space outside the limits cannot be filled with any light source.
[0142] In Figure 4, McCree values are plotted as a function of PSS for different light sources. In this respect, as defined in the literature, PSS = Pr / (Pr + Pfr). Figure 5 shows phototropin versus PSS and Figure 6 shows phototropin versus McCree. It should be noted that in particular, the PSS parameter introduces non-linearity. Therefore, it is difficult for a knowledgeable person to interpret distances in the graphs. Figures 4 to 6 provide insight into the horticultural action space. The tables show different sources of light in relation to each other and their influence on plants.
[0143] Figures 7 to 9 show views of the horticultural action space in the x, y plane, in the y, z plane and in the x, z plane. In such views, several existing and theoretical lighting devices are plotted. The limits show all possible values that can be physically realized. In this way, every point within that area can be produced. In addition, several symbols show the coordinates of the horticultural action space of these lighting devices. Due to the fact that this horticultural action space is normalized, it is possible to observe relatively easily the effect of lighting devices. Furthermore, this space is linear. This means that, in fact, a line can be drawn between the light sources and any point on that line is a combination of these two light sources. And, in fact, all of these points represent an effect on plants of the combination of light sources. In addition, the relative position of the line corresponds to the relative number of light sources. For example, half a line between a light source A and a light source B means the effect of combining an equal number of light sources A and B.
[0144] In Figures 7 to 9, the small dots show, again, the effect of monochromatic light sources in the horticultural action space, as well as in Figures 4 to
[0145] In this example, the lighting devices that are indicated are indicated "Deep red LED 660 nm", "Far red LED 740 nm" and "Blue LED 450 nm" in Figures 7 to 9. Such lighting devices are , in fact, approximately monochrome fonts. The lines now connect these different lighting devices. Such lines actually connect a triangle in the plane (x, y). With the use of these three lighting devices, all points in such a triangle, including the lines, can be realized. In reality, the definition of the horticultural action space takes place in such a way that the position within and on the triangle corresponds to the absolute reasons of the lighting devices. Thus, for example, the position in the middle of the line connecting "450 nm blue LED" and "660 nm deep red LED" corresponds to the use of such lighting devices in a 1: 1 ratio in relation to their absolute output .
[0146] In Figures 10 to 15, several possible implementations of the interface are illustrated in schematic drawings. Figure 10 shows a basic configuration of interface 20 functionally coupled to a lighting system 4, 12. Figure 11 shows the implemented interface 20 and a climate computer 9 in a greenhouse. Figure 12 shows the interface 20 separate from the climate computer 9. Figure 13 shows the interface 20 implemented in a lighting control device 24. Figure 14 shows a modality of interface 20 implemented in a sensor. Figure 15 shows a modality of a basic configuration of an interface with a lighting system interface part.
[0147] In the embodiment of Figure 10, interface 20 comprises an interface portion 23 of light recipe. The light recipe interface part 23 is adapted to receive a light recipe. Such a light recipe comprises at least one target point in a horticultural action space. The target point in the horticulture action space defines a desired physiological plant response. The interface 20 is, at its input end, functionally coupled to a light recipe database 21 that contains one or more light recipes 22. At its output end, the interface 20 is functionally coupled to one or more systems lighting 4, 12. In this respect, interface 20 will be coupled, frequently, through a wired or wireless connection.
[0148] In the modality of Figure 11, interface 20 is installed on climate computer 9. Interface 20 can be completely integrated into the climate control software that runs on climate computer 9. Alternatively, interface 20 can be incorporated in a complement or an application, which exchanges data with the climate control software. The climate computer 9 is functionally coupled to a lighting system 4, 12, which comprises, in this document, one or more light emission sources 25 and a lighting controller 24. Such lighting controller 24 is integrated in this document, in light emission sources, but other implementations may be possible.
[0149] In an embodiment of Figure 12, the interface 20 is implemented separately from the climate computer 9. In this embodiment, the climate computer 9 is functionally coupled to a remote light recipe database 21. The climate computer 9 is functionally coupled to interface 20. Interface 20, in turn, is functionally coupled to one or more lighting systems, schematically indicated, so that it has one or more light sources 25 and a lighting controller 24. In reality, in this mode, interface 20 is functionally coupled to the lighting controller 24.
[0150] In Figure 13, a modality is indicated, with interface 20 being, in reality, integrated with the lighting controller 24. In one modality, they share a common housing.
[0151] In Figure 14, interface 20 is functionally coupled to a sensor to measure one or more lighting parameters. In reality, this modality is one of several possible modalities. In this embodiment, detector 26 for detecting ambient light radiation is functionally coupled to a processing part 27. Detector 26 provides, for example, a signal representative of at least the light intensity. Often, such a signal comprises intensity as a function of wavelength: I (À).
[0152] In a state of the art sensor, the output signal can be supplied to a climate computer 9. In this mode, detector 26 is functionally coupled to processing device 27 to provide intensity data based on wavelength . Such data is provided to the climate computer 9. In this embodiment, the processing device 27 is also functionally coupled to interface 20. Interface 20 can also be functionally coupled to the climate computer 9 and lighting system 4, 12.
[0153] In Figure 15, another modality of interface 20 is illustrated. In this embodiment, the interface 20 is provided with a lighting system interface part 28. The lighting interface part 28 receives coordinates of horticultural action space and emits a control signal S to control a lighting controller (not shown) ). EXAMPLE
[0154] An example of using a light recipe is growing tulips as cut flowers. In this example, growth occurs in a three-tiered greenhouse. Growth occurs between weeks 46 and 15 in a northern hemisphere environment in a greenhouse.
[0155] Light sources are LED production modules that have both white and blue LEDs in combination with red LEDs.


[0156] For unit # 1: photons of 5.0 pmol are an optical power of 1 W and a Y of 0.89 / m2
[0157] For unit n ° 2: photons of 5.2 pmol are an optical power of 1 W and a Y of 0.9 / m2
[0158] It is interesting to note that the values of PSS, Y and Z are approximately equal for both types of lamp. This means, therefore, that the effect on plants is the same and these two devices are interchangeable although the spectral composition is totally different.
[0159] This way:
[0160] 15 s 30 pmol / s / m2 for unit n ° 1 = optical power of 3.0 to 6.0 W / m2, a Y value of 2.67 to 5.34 and an action point of horticulture of (0.32, 0.52, 0.064).
[0161] 15 to 30 pmol / s / m2 for unit no. 2 = optical power of 2.9 to 5.8 W / m2, a Y value of 2.61 to 5.22 and an action point of horticulture of (0.36, 0.47, 0.058);
[0162] Both units have a different horticultural action point, however, the PSS and phototropin action values are comparable by means of a comparable light intensity. That way, the plant response will be comparable. The difference may be that unit # 1 is less energy efficient, thus requiring greater installed power.
[0163] Light sources with the same color point and Y value have the same effect on plant growth, so they are comparable, however, other factors such as better color rendering (for the human eye) needed than the grower monitor the health of the plant or the power consumption of the lamp and the price can now be purchased.
[0164] In this case, a light recipe can be:
[0165] Day 0 to 7: (x, y, x) = (0.36, 0.47, 0.058) and Y = 1.36 or (x, y, z) = (0.32, 0.52 , 0.064) and Y = 1.56;
[0166] Day 8 to 14 Sunlight;
[0167] Day 15 to 21 (x, y, z) = (0.36, 0.47, 0.058) and Y = 2.72 or (x, y, z) = (0.32, 0.52, 0.064) and Y = 3.12.
[0168] Photon flow calculation:

[0169] (NA = Avogadro's number; h = Planck's constant; c is the speed of light)
[0170] It will also be evident that the description above and the drawings are included to illustrate some modalities of the invention and not to limit the scope of protection. From the present disclosure, several additional modalities will become evident to a knowledgeable person, the same being covered by the scope of protection and the essence of this invention and which are obvious combinations of prior art procedure sets and the disclosure of this patent.
