BACKGROUND

The need for fresh food is growing as the population increases and changes in the climate impact growing seasons. The current food supply model, based on traditional farming methods and long distance shipping, is economically and environmentally unsustainable. Traditional farming operations are usually located in agricultural areas, which require large upfront costs and large acreage and have high operational costs from seed to sale.

Urban and local agriculture also face obstacles. Growing space in urban areas is limited and not sufficient to meet a high demand. High start-up and operating costs of greenhouses make local crop production difficult for many businesses. Structures intended to support rooftop greenhouses must be evaluated by structural engineers and often require additional bracing to support the weight. Urban gardens often must address contaminated soil. Hydroponic systems are not easily used in urban locales, as most hydroponic systems are meant to be installed in agricultural settings, are not easily transportable, and require extensive training of personnel for operation.

Contained agricultural systems have recently been developed to address these issues. For example, a growing system in a modular container, described in U.S. Pat. No. 9,288,948, has been developed for generating high-yield crops. Within the modular container, the growing system includes a germination station for nurturing seeds until they germinate into plants, a plurality of vertical racks to hold the growing plants, a lighting system to provide appropriate light for the plants, an irrigation system to provide nutrients to the plants, a climate control system to control the environmental conditions within the container, a ventilation system for providing airflow to the plants, and a monitoring system to monitor and control the components of the growing system.

DETAILED DESCRIPTION OF THE INVENTION

An embodiment of a device10for growing plants is illustrated inFIGS. 1-2. The device10includes a panel assembly12providing one or more grow pockets40on one side of the device in linear alignment with one or a plurality of nutrient flow channels30on an opposite side of the device. Each nutrient flow channel extends from an inlet32to an outlet34and is in fluid communication with the one or more grow pockets via fluid apertures50through a support panel. The device illustrated inFIG. 1includes six columns of fifteen grow pockets in linear alignment with six nutrient flow channels. It will be appreciated, however, that any number of grow pockets and any number of nutrient flow channels can be provided, depending on the application and the space available.

In the embodiment shown, the panel assembly12is formed from a number of discrete panel assemblies12′ that are attachable along vertical edges. Each panel assembly12′ provides a single column of vertically aligned grow pockets on one side and a single nutrient channel on the opposite side. In this manner, any desired number of discrete panel assemblies12′ can be produced and attached together. It will be appreciated that the panel assembly12can also be formed as a unitary or integral panel assembly with multiple columns of grow pockets and multiple nutrient channels, described further below.

FIGS. 3-11illustrate with more particularity an embodiment of a panel assembly12′ with a single column of grow pockets. The panel assembly12′ includes a support panel14having a front face16and a back face18. A nutrient flow channel30is supported on the back face of the support panel, and one or more grow pockets40are supported on the front face of the support panel in linear alignment with the nutrient flow channel. The nutrient flow channel is in fluid communication with the one or more grow pockets40on the front face of the support panel via fluid apertures50through the support panel14.

Each grow pocket40includes a plant access opening42at an upper region of the grow pocket. A growing medium3can be placed in each grow pocket, and a seed or plant5can be placed in the growing medium. SeeFIGS. 4 and 8. A plant nutrient solution can be fed through the nutrient flow channel30from the fluid inlet32at an upper region of the panel assembly to the fluid outlet34at a lower region of the panel assembly. The nutrient solution flows downwardly indicted by arrow31inFIG. 8. As the nutrient solution flows past the fluid apertures50in the support panel, an amount of the nutrient solution also flows through the fluid apertures50into the growing medium in each grow pocket40(indicated by arrows52inFIGS. 8 and 10), thereby keeping the growing medium moist and the growing plant5nourished.

In some embodiments, the panel assembly12includes a front panel22and a back panel24fastened to the support panel14in a layered arrangement (seeFIGS. 7-11) along bond lines that form the grow pockets40and the nutrient flow channels30. In particular, bond lines62between the support panel14and the front panel22define an outline of each grow pocket. In the embodiment shown, the bond lines62are generally tapered downwardly along each side63to a closed bottom65below the fluid aperture50. Bond lines64between the support panel14and the back panel24define each nutrient flow channel. Bond lines68between the support panel14and the back panel24can be provided to define baffles to direct fluid flow toward the fluid apertures50. In this way, no or minimal nutrient solution bypasses the fluid apertures, thereby preventing or minimizing waste of the nutrient solution. For ease of manufacture and to strengthen the panel assembly, the bond lines between the back panel and the support panel can also bond to the front panel, as described further below; however, it will be appreciated that the back panel does not need to be bonded to the front panel to provide elements such as the nutrient flow channels, fluid inlets, fluid outlets and baffles.

The fluid inlets32can be connected to a liquid nutrient solution source74, which can be fed into each nutrient flow channel30for flow downwardly between the lines64to the fluid outlets34at or near the bottom of the support panel12. The outlets can be connected to a collection reservoir76for the nutrient solution. Tapered bond lines66can be provided to direct flow from the inlet32into the channel30, and tapered bond lines67can be provided to direct flow from the channel30to the outlet34.

The panel assembly can include any suitable mounting fixtures to mount the assembly in a vertical orientation. In some embodiments, the device can be suspended in a vertical orientation from an overhead fixture. In some embodiments, the device can include openings72along the upper edge. The openings can be reinforced with grommets73. Hooks or other suitable suspension elements can be placed through the openings and suspended from an overhead bar or another form of support element. It will be appreciated that many other suspension mechanisms can be provided.

In some embodiments, the panel assembly can include additional structural elements to provide stiffening and/or to assist the panel assembly in remaining in an upright or vertical orientation.FIGS. 13 and 14illustrate an embodiment in which a rib78is disposed adjacent and parallel to a nutrient flow channel, for example, by welding or inserting in an elongated pocket formed adjacent to the flow channel. In some embodiments, the vertical edges of discrete panel assemblies12′ can be configured to provide structural support for a panel assembly when fastened together.FIG. 15illustrates an embodiment in which ribs78′ are attached between and/or alongside panel assemblies to form stiffening elements. The ribs can be, for example, plastic, metal, or composite material rods. In some embodiments, flexible fiberglass or other rods can be used. In some embodiments, the panel assembly can be mounted on a stand supported on a floor.FIG. 16illustrates an embodiment in which supporting rods79are attached in any suitable manner at several locations to the panel assembly to form mounting points. Each rod can be placed in a support fixture at a lower end and/or attached to a support fixture at an upper end. In some embodiments, the vertical edges of one or more panel assemblies can include inflatable channels that upon inflation with air or another fluid can be used to provide stiffening and/or structural support.

In some embodiments, separate input conduits81can be provided at the top of the panel assembly for connection to each inlet32of the nutrient flow channels30. SeeFIGS. 1-3. Fittings83can be affixed to the input conduits for connection to an input manifold or to one or more input conduits from a nutrient solution source74. A separate output conduit85can be provided at the bottom of the panel assembly for connection to each outlet34of the nutrient flow channels30. The output conduit can drain to a collection reservoir76.

In some embodiments, an input manifold90can be located at the top of the panel assembly to receive the nutrient solution from a nutrient solution source and distribute it to each of the nutrient flow channels30. SeeFIG. 12. In some embodiments, a manifold can be formed as a separate element that can be retained between the support panel and the back panel, for example, with or between bond lines between the back panel and the support panel. For example, the manifold can be formed from two sheets of material bonded together along a perimeter to define the manifold. The manifold can include an inlet92and a plurality of outlets94, each outlet aligned with an inlet32of a nutrient flow channel30. An input conduit96can be fixed to the inlet of the manifold, for example, by mandrel welding.

In some embodiments, a collection manifold110can be located at the bottom of the panel assembly to direct an outflow of the nutrient solution to a discharge outlet112at the bottom of the panel. SeeFIG. 12. The collection manifold can be formed by bond lines114angled to direct the nutrient solution toward the outlet112.

In some embodiments, the collection reservoir76can be located beneath the panel assembly, and nutrient solution can drain directly down into the collection reservoir. SeeFIG. 3. In some embodiments, the collection reservoir can be located at a distance from the panel assembly and can be connected to the panel assembly via any suitable conduit116. SeeFIG. 12.

In some embodiments, each of the support panel14, the front panel22, and the back panel24can be provided as a sheet or film of a flexible material. The sheets for the panels are generally the same height. The back panel can be slightly wider than the support panel so that after bonding each nutrient flow channel has some slack to provide depth to each fluid flow passage and allow room for root growth. The sheet material can be in any suitable thickness. In some embodiments, the sheets are 6-10 mils (0.006-0.010 inch) in thickness. The sheet material can be any suitable material, such as, without limitation, polyvinyl chloride, polyethylene, or polypropylene. The material is waterproof to retain the nutrient solution in the nutrient flow channels and the grow pockets. In some embodiments, the sheet can be a semi-rigid polymer material or a fibrous material. In some embodiments, the sheet can have some rigidity or stiffness or can be formed to be self-supporting or self-standing. In some embodiments, the sheet can also be a laminate of two or more materials. In some embodiments, a waterproof liner can be bonded to a different material that provides strength. In some embodiments, one or more sheets can be formed from a composite material, such as a fiberglass composite material. In some embodiments, one or more of the sheets can be a fibrous material or a textile, such as a woven, non-woven, knit or braided material. In some material, one or more of the sheets can be a foam material. The sheets can be made from recycled materials. One or more of the sheets can include a water proof coating on at least those surfaces that come in contact with the nutrient solution. The material can be opaque, or the material can be transparent or translucent to allow visual inspection into the grow pockets and the nutrient flow channels. An opaque material for at least the grow pockets can be beneficial for root growth.

The device can be manufactured in any suitable manner. In one embodiment, each of the support panel14, the front panel22, and the back panel26is provided as an appropriate sheet material cut to a desired height and width. The access openings42for each grow pocket are cut into the front panel. In the embodiment shown, the cuts for each pocket include a first slit122extending horizontally and a second slit124extending orthogonally downwardly from the first slit. The access opening can be further widened, for example, by removing a triangular portion126of the sheet material adjacent the slits, thereby providing increased access to the grow pocket. SeeFIG. 7. The fluid apertures50are cut into the support panel14for alignment with the lower regions of the grow pockets. In some embodiments, openings72near upper edges of each of the panels can be cut to receive appropriate fixtures for mounting the panel assembly in a growing environment, such as a modular growing container. Any suitable cutting mechanism or technique can be used, such as die cutting, laser cutting, water jet cutting, stamping, or the like.

After the panels have been appropriately cut, the support panel14and the front panel22are overlaid with the slits and cut out portions in appropriate alignment. The support panel and the front panel are bonded together along lines62defining an outline of each grow pocket40. The grow pocket can be bonded with some slack to provide room for root growth within the growing medium. The bonded support panel and front panel form a subassembly. The back panel24is then overlaid on the subassembly adjacent to the support panel. The back panel and subassembly are bonded together along bond lines that join all three panels together. The nutrient flow channels30are formed by bond lines64extending from a region near the upper edge of the panels to a region near the lower edge. The bond lines64are arranged so that each column of grow pockets40is aligned between two bond lines64that define a nutrient flow channel30. As noted above, the back panel can be bonded to the subassembly with a small amount of slack in each nutrient flow channel to provide a depth dimension to the flow channel. Angled bond lines66can be formed at the inlet32, and angled bond lines67can be formed at the outlet34. The baffles can be formed by one or two pairs of angular bond lines68within the nutrient flow channel adjacent to the lower region of each grow pocket to direct the flow of a nutrient solution in the nutrient flow passage toward the fluid aperture at the base of each grow pocket.

In some embodiments, discrete panel assemblies can be attached via bond lines75along their vertical edges to form a larger panel assembly. SeeFIGS. 1 and 2. The bond lines can be discontinuous to avoid apertures69that can be formed along the vertical edges to support the panels in the equipment during the manufacturing process.

In some embodiments, bond lines114can be formed to define the collection manifold112at the bottom of the device. In some embodiments, the input manifold90can be formed from a suitable material and retained within the panel assembly, between the support panel and the back panel, by suitable bond lines at the top of the panel assembly. SeeFIG. 12.

To form any of the bond lines, any suitable bonding mechanism or technique can be used, such as, without limitation, radio frequency welding, ultrasonic welding, heat sealing, adhesive bonding, mechanical fasteners, or stitching. If necessary, such as with bond lines formed by mechanical fasteners or stitching, additional water proofing or seam sealing can be applied along the bond lines. Input and output conduits can be affixed to the panel assembly in any suitable manner. In some embodiments, conduits can be affixed by welding, such as mandrel welding, or with mechanical fasteners, such as barbs, or with a combination thereof.

Any number of grow pockets can be provided on a panel assembly. Each column can contain any desired number of grow pockets, and any desired number of columns of grow pockets can be provided. The particular number and spacing of grow pockets can depend on factors such as space constraints within a modular container, the desired crops, and the desired crop density. In some embodiments, a single grow pocket can be provided. Similarly, the size of each grow pocket can be selected for the desired crop and crop density. In some embodiments, each grow pocket is sized to contain at least about 100 mm3of a plant growth medium therein, although the grow pockets can be sized to contain a greater or lesser volume of the plant growth medium if desired. In some embodiments, grow pockets of different sizes can be provided.

In some embodiments, the nutrient flow channels can be provided as separate strips of a flexible sheet material bonded to the back face of the support panel. In some embodiments, each column of a nutrient flow channel and aligned grow pockets can be formed as a separate panel assembly. Any number of separate panel assemblies can be attached together along longitudinal edges, parallel to the nutrient flow channels and columns of grow pockets. The panel assemblies can be attached by any suitable bonding mechanism, as discussed above.

In some embodiments, a panel assembly can include a single grow pocket. In some embodiments, two or more panel assemblies, each panel assembly including a single grow pocket or multiple grow pockets in a columnar arrangement, can be attached together in a single column. Any suitable bonding mechanism, as discussed above, can be used.

In some embodiments, two or more panel assemblies can be attached together to provide any desired configuration of grow pockets to suit a desired application or growing space. In some embodiments, two or more panel assemblies can be removably attached, to provide a modular device that can be reconfigured to suit different applications or different growing spaces.

In some embodiments, two panel assemblies can be installed in a growing environment back to back, such that two back panels are in contact or close contact with each other. In this manner, efficient use of space within the growing environment can be made, and a greater plant density can be achieved. In some embodiments, a panel assembly with grow pockets on opposite outer faces and inner shared nutrient flow channels can be provided.
