    DK 2020 00066 A1 1 A hydroponic system, and a method for producing a hydroponic system Technical field of the invention The present invention relates to hydroponic production of plants.
    Background of the invention Hydroponics is a subbranch of hydroculture, which is a method of growing plants with a minimal amount of soil.
    The nutrients are supplied dissolved in water.
    The nutrients may be supplied by use of a Nutrient Film Technique (NFT) system.
    An NFT system is a recirculating hydroponic system that consists of long channels or trays through which a nutrient solution is constantly pumped, creating a nutrient film into which the roots grow.
    Plants are often started in plastic pots with stone wool inside and then placed in the growing channels or trays.
    This is very problematic, as there is a dramatic increase of plastic waste in general in the world, and stone wool needs to be collected and deposited.
    Furthermore, when the herbs are harvested, the plastic pots and stone wool are seldom separated from the root and growth medium, and both parts are therefore not recycled.
    Description of the invention It is an object of the present invention to provide an alternative hydroponic system to replace the environmentally unfriendly system with injection moulded plastic pots
    — with stone wool.
    A first aspect relates to hydroponic system comprising: - an elongated hydroponic reservoir comprising a plurality of cavities adapted for receiving a growth medium pot or bag; and
    — -a plurality of growth medium pot or bags positioned within said cavities; wherein the growth medium pot or bag comprises an amount of growth medium held in an water and air permeable sheet material.
    By using a water and air permeable sheet material, preferably biodegradable, woven or nonwoven, there is no need for the environmentally unfriendly injection moulded plastic pots with stone wool.
    Rather, the water and air permeable sheet material
    DK 2020 00066 A1 2 may be recycled together with the plant roots and growth medium. The sheet material must be water and air permeable in order for the produced plant pot to be able to absorb water and dissolved nutrients. The hydroponic system may be line produced by the method according to the present invention.
    The growth medium pot or bag may in one or more embodiments have a closed bottom end to avoid that growth medium will fall out of the pot or bag and into the pot or bag trays of the hydroponic system, thereby obstructing filters and pumps.
    The term “biodegradable” as used herein describes the chemical dissolution of materials by bacteria or other biological means.
    As used herein, the term “nonwoven sheet material” means a sheet material that has a structure of individual fibers or threads, which are interlaid, but not in an identifiable repeating manner. Nonwoven sheet materials may be formed by a variety of processes such as, for example, meltblowing processes, spunbonding processes, coforming processes, airlaying processes, wetlaying processes, and hydroentangling.
    — The fibers used for the water permeable sheet material are preferably biodegradable, which can be natural or synthetic fibers, e.g. cellulosic fibers, protein fibers or synthetic polymer fibers. Natural fibers can comprise pulped or shredded cellulose fibers, such as wood pulp, shredded wood, shredded paper (tissue, newsprint and the like), straw, cotton fiber, composted vegetation, fibrous sphagnum moss, peat moss, shredded stalks including shredded corn stalks and shredded pine straw (including needles, twigs, cones and small branches). Shredded vegetation is preferably dry before shredding. Protein fibers can e.g. be hair or gelatin. Biodegradable synthetic fibers can comprise reconstituted cellulose fibers, such as rayon fibers, vinyl polymer fibers, such as fibrous polyvinyl alcohol, poly lactic acid, and polyamide fibers.
    The term “cellulosic fibers” as used herein describes fibers made from an organic compound derived primarily from plants such as trees.
    DK 2020 00066 A1 3 The term “wood pulp fibers” as used herein describes a type of cellulosic fiber made from a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulosic fiber from plants such as trees or cotton. The term “regenerated/reconstituted cellulosic fibers” as used herein describes a type of cellulosic fiber made from wood pulp using a solvent fiber spinning process. The process involves dissolving wood pulp in a solvent and spinning the resultant spinning solution into fibers.
    In one or more embodiments, the biodegradable and water permeable sheet material consist of spunlaced fibers without fiber binding materials. The term "spunlaced" as used herein refers to a structure of individual fibers or threads, which are physically entangled, without thermal bonding. Physical entanglement may be achieved using a water entanglement process, or alternatively, a needling process or a combination of both processes. The spunlaced fibers provide the strength to the water permeable sheet without the need for a binder, also, and very importantly for the present use, when the water permeable sheet is wet.
    In order for the water permeable sheet material to be sealable, at least some of the fibers should preferably be made from, or coated with, a thermoplastic material. Alternatively, the water permeable sheet material could be coated with a hotmelt composition. Another method for sealing the sheet material tube may be to emboss or sew the sheet parts together.
    In one or more embodiments, the water permeable sheet material is heat sealable. In one or more embodiments, the water and air permeable sheet material comprises a) fibers coated with a thermoplastic material and/or b) fibers of a thermoplastic material; and wherein the sealings are made by heating.
    In one or more embodiments, the sheet material is formed as a tube or cylinder covering the amount of growth medium.
    DK 2020 00066 A1 4 In one or more embodiments, the tubular, or cylindrical sheet material is open in at least one of the ends. In one or more embodiments, the pot or bag comprises a cavity adapted for receiving a seed or a seedling. The seedling may be a potted seedling, and hence, the pot or bag comprises a cavity adapted for receiving a plant pot or bag. Obviously, such a pot or bag is relatively smaller than the pot or bag with the cavity. The cavity may be formed by drilling or indentation. A drilled cavity is preferably suitable for receiving a seedling in a plant pot or bag. An indented cavity is preferably suitable for receiving a seed and may be formed by punching a dibble into the pot or bag, preferably into a part of the growth medium not covered by the sheet material. Hence, the pot or bag preferably comprises an open top end, when comprising a cavity adapted for receiving a seed or a seedling.
    In one or more embodiments, the elongated hydroponic reservoir is a tube, pipe, or gutter. Preferably, the elongated hydroponic reservoir comprises means adapted for supporting the sides of the pot or bag. Such means may be the edges of holes formed in the upper wall of the tube, pipe, or gutter. In this situation, the pot or bag extends upwards through said holes. The length of the elongated hydroponic reservoir may vary, but is preferably at least 2 meters long, such as within the range of 2-50 meters, e.g. at least 3 meters, such as within the range of 3-45 meters, e.g. at least 4 meters, such as within the range of 4-40 meters, e.g. at least 5 meters, such as within the range of 5-35 meters, e.g. at least 6 meters, such as within the range of 6-30 meters, e.g. at least 7 meters, such as within the range of 7-25 meters, e.g. at least 8 meters, such as within the range of 8-20 meters, e.g. at least 9 meters, such as within the range of 9-15 meters, e.g. at least 10 meters.
    In one or more embodiments, each of the plurality of growth medium pots or bags comprises a cavity in their top, and wherein said cavity is filled with a seedling in a plant pot or bag.
    In one or more embodiments, each of the plurality of growth medium pots or bags comprises a cavity in their top, and wherein said cavity contains a seed.
    DK 2020 00066 A1 A second aspect relates to a process for producing a hydroponic system according to the present invention, comprising the steps of: i) providing an elongated hydroponic reservoir; and ii) positioning a plurality of growth medium pots or bags within said hydroponic 5 reservoir; wherein each of said growth medium pots or bags comprises an amount of growth medium held in a water and air permeable sheet material. In one or more embodiments, the process further comprises the steps of: iii) drilling or indenting a cavity in the top of said growth medium pots or bags; and iv.a) inserting a seedling in a plant pot or bag into a cavity of each of said growth medium pots or bags; or iv.b) positioning or dropping a seed into a cavity of each of said growth medium pots or bags.
    In one or more embodiments, the process further comprises the steps of: iii) drilling a cavity in the top of said growth medium pots or bags; and iv) inserting a seedling in a plant pot or bag into a cavity of each of said growth medium pots or bags.
    In one or more embodiments, the process further comprises the steps of: iii) indenting a cavity in the top of said growth medium pots or bags; and iv) inserting a seedling in a plant pot or bag into a cavity of each of said growth medium pots or bags.
    In one or more embodiments, the process further comprises the steps of: iii) indenting a cavity in the top of said growth medium pots or bags; and iv) positioning or dropping a seed into a cavity of each of said growth medium pots or bags.
    In one or more embodiments, the process further comprises the steps of: iii) drilling a cavity in the top of said growth medium pots or bags; and iv) positioning or dropping a seed into a cavity of each of said growth medium pots or bags.
    DK 2020 00066 A1 6 A third aspect relates to a hydroponic system produced by the process according to the present invention. A fourth aspect relates to a system for use in the process according to the present invention, comprising: - a conveyor system adapted for transporting an elongated hydroponic reservoir; - a growth medium pot or bag distributor unit adapted for positioning growth medium pots or bags into said elongated hydroponic reservoir; - atleast one of a drilling unit and indentation unit, the drilling unit adapted for drilling a cavity in the top of a growth medium pot or bag positioned within said hydroponic reservoir, and the indentation unit adapted for indenting a cavity in the top of a growth medium pot or bag positioned within said hydroponic reservoir; and - at least one of a seedling delivery unit and a seed delivery unit, the seedling — delivery unit adapted for inserting a seedling in a plant pot or bag into a cavity of said growth medium pot or bag, and the seed delivery unit adapted for positioning or dropping a seed into a cavity of each of said growth medium pot or bags; wherein the conveyor system is adapted for transporting an elongated hydroponic reservoir through said growth medium pot or bag distributor unit, at least one of a — drilling unit and indentation unit, and at least one of a seedling delivery unit and a seed delivery unit.
    The conveyor may comprise one or more conveyors, e.g. a first conveyor positioned upstream to the growth medium pot or bag distributor unit, and a conveyor positioned downstream to the growth medium pot or bag distributor unit. The first conveyor may be a stepper conveyor, which is configured to move the hydroponic reservoir in successive distance movements, also called discrete step increments. The first conveyor may be a belt conveyor driven by an electric stepper motor to producing a torque to the pulley so by friction of the conveyor belt on the powered pulley the conveyor belt and the load is moved in a conveying direction. A stepper motor is commonly used for position control. The use of an electric stepper motor makes the transport of the hydroponic reservoir more controllable, e.g. to change the speed of conveying and move the hydroponic reservoir on the conveyor belt in successive distance movements. These successive distance movements allow the
    DK 2020 00066 A1 7 growth medium pot or bag distributor unit, drilling unit, and indentation unit enough time to perform their action at a specific location relative to the hydroponic reservoir. The growth medium pot or bag distributor unit will have time to position a growth medium pot or bag at a specific position within the hydroponic reservoir, and the drilling unit and indentation unit will have enough time to act on a positioned growth medium pot or bag. The growth medium pot or bag distributor unit may be of any type known within the art being configured for distributing, and optionally also producing, growth medium pots or bags comprising an amount of growth medium held in a water and air permeable sheet material. Suitable types of distributor unit may be as disclosed in WO2017216146, WO2017216145, or WO19001944, hereby incorporated by reference.
    In one or more embodiments, the distributor apparatus comprises a growth medium pot or bag production unit. Such a unit may be as disclosed in WO1992003914 or WO19011742, hereby incorporated by reference.
    The system also comprises at least one of a drilling unit and indentation/dibbling — unit. The drilling unit and the indentation unit may be present in the same system. In this situation, the system further comprises a controller configured for activating either the drilling unit or the indentation unit. The drilling unit adapted for drilling a cavity in the top of a growth medium pot or bag positioned within the hydroponic reservoir. The drilling unit may e.g. comprise a column drill and optionally means adapted for removing the by the drill removed growth medium. The indentation unit is adapted for indenting a cavity in the top of a growth medium pot or bag positioned within the hydroponic reservoir and may comprise a dibble tool.
    The system also comprises at least one of a seedling delivery unit and a seed delivery unit. The seedling delivery unit and the seed delivery unit may be present in the same system. In this situation, the system further comprises a controller configured for activating either the seedling delivery unit or the seed delivery unit. The seedling delivery unit is adapted for inserting a seedling in a plant pot or bag into a cavity of said growth medium pot or bag. The seedling delivery unit may e.g.
    DK 2020 00066 A1 8 comprise a robotic arm or a distributor adapted for positioning or dropping the seedlings positioned in a plant pot or bag into the cavity of the relatively larger growth medium pot or bag positioned within the hydroponic reservoir. The seed delivery unit is adapted for positioning or dropping a seed into a cavity of each of said growth medium pot or bags, and may e.g. comprise a distributor adapted for positioning or dropping a seed into the cavity of the relatively larger growth medium pot or bag positioned within the hydroponic reservoir. Such seeding equipment is known within the art and may e.g. be a drumseeder, needleseeder, transplanter, or the like.
    As used in the specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Ranges may be expressed herein as from "about" or "approximately" one particular value and/or to "about" or "approximately" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about", it will be understood that the particular value forms another embodiment.
    It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention. Brief description of the figures Figures 1-5 show different views of a system for line production of a hydroponic system according to various embodiments of the present invention. Detailed embodiments of the invention Figures 1-5 show different views of a system for line production of a hydroponic system according to various embodiments of the present invention. The shown system is capable of handling nine juxtaposed hydroponic reservoirs at the time but may be used with fewer and can also be configured to handle even more. Figure 1 shows a perspective view of the system. The system comprises a conveyor system
    DK 2020 00066 A1 9 110, 120 adapted for transporting (juxtaposed) elongated hydroponic reservoirs 210; a growth medium pot or bag distributor unit 130 adapted for positioning growth medium pots or bags 220 (Figure 4) into elongated hydroponic reservoirs 210; an indentation unit 140 adapted for indenting/dibbling a cavity (not shown) in the top of a growth medium pot or bag 220 positioned within said hydroponic reservoir 210;
    and a seed delivery unit 150 adapted for positioning or dropping a seed into a cavity of each of said growth medium pot or bags 220. Figure 2 shows a closeup view of the end of the system where the hydroponic reservoirs 210 are loaded.
    A first conveyor 110 is shown positioned upstream to the growth medium pot or bag distributor unit 130. Nine hydroponic reservoirs 210 are positioned side by side on the first conveyor 110. The hydroponic reservoirs’ 210 ends are aligned by a two-part mechanism being part of the conveyor system.
    The first conveyor 110 comprises a belt with baffles 112 adapted for supporting the first
    — end of the hydroponic reservoirs 210. At the end (beck end) of the first conveyor 110 closest to the growth medium pot or bag distributor unit 130, the other part of the two-part mechanism is mounted in the form of an alignment boom barrier 160 adapted for supporting the second opposing end (front end) of the hydroponic reservoirs 210. Figure 3 shows a closeup view of the alignment boom barrier 160. A pole 164 is pivotably attached to a chassis 162 via arms (only one is shown) 165. The pole 164 is adapted to act as a temporary stop for the hydroponic reservoirs 210 until the baffles 112 pushes, via the belt movement, on the back end of the hydroponic reservoirs 210. Then the pole 164 moves upwards (the arms 165 pivot) onto the top surface of the hydroponic reservoirs 210. This movement is aided by wheels 166, e.g. configured as ball bearings, thereby allowing the hydroponic reservoirs 210 to pass while the wheels 166 role on the top surface of the hydroponic reservoirs 210. In some embodiments, and also shown here, a sensor 168 is configured for sensing when the boom 164 initiates its movement towards the top of the hydroponic reservoirs 210. The arms 165 each comprise a spring 163 allowing them to vary their length.
    The pole 164 is attached to a second set of arms configured as hydraulic or pneumatic piston 161. The sensor 168 then activates the hydraulic or pneumatic piston 161, thereby extending the arm length to ease the movement of the pole 164 towards the top of the hydroponic reservoirs 210. The sensor 168 may e.g. be an inductive sensor.
    DK 2020 00066 A1 10 Figure 4 shows a closeup view of the system at the location of the indentation unit
    140. A hydroponic system has just been produced and is forwarded to the seed delivery unit 150 (Figure 1) adapted for positioning or dropping a seed into a cavity of each of said growth medium pot or bags 220. Similarly, to the mechanism aligning the hydroponic reservoirs 210 before loading the growth medium pot or bags 220 therein, the hydroponic reservoirs’ 210 ends may also be aligned by a two-part mechanism being part of the conveyor system. The second conveyor 120 comprises a belt with baffles 122 (Figure 3) adapted for supporting the first end of the hydroponic reservoirs 210. At the end (beck end) of the second conveyor 120 closest to the seed delivery unit 150, the other part of the two-part mechanism is mounted in the form of an alignment boom barrier 170 adapted for supporting the second opposing end (front end) of the hydroponic reservoirs 210 (Figure 5). The alignment boom barrier 170 may be constructed identically to the other alignment — boom barrier 160. Alternatively, if the second conveyor 120 is provided with a belt without baffles 122, a different mechanism may substitute the alignment boom barrier 170. This mechanism will simply provide a pressure on top of the hydroponic reservoirs, such that friction between the belt under the seed delivery unit and said hydroponic reservoirs will be enough to forward the latter.
