Description

Technical Field

[0001] This application relates to systems, methods, and apparatus for irrigating crops via hydroponics, and in particular to a hydroponic system and reusable planting plugs. Background Technology

[0002] In hydroponic systems, plants typically grow in a water-based, nutrient-rich solution, eliminating the need for extensive arable land and nutrient-rich soil. Hydroponic agriculture is a rapidly developing industry because it has the potential to address global food shortages, climate change, and social transformation by moving away from traditional soil- and land-based agricultural techniques.

[0003] Many hydroponic systems rely on modular, vertically stacked arrangements to maximize space utilization and increase the yield per unit area. However, vertically stacked hydroponic systems can be labor-intensive and challenging in terms of inspecting and harvesting crops. Furthermore, hydroponic systems can be expensive due to their complex pumping systems.

[0004] Several rotating hydroponic systems have been developed, such as Bace Inc.'s Rotofarm and OmegaGarden. TM These hydroponic systems rely on rotating cylindrical rollers to create a net-zero gravity environment for the grown crops. This interferes with the crops' geotropism and is believed to lead to faster growth rates. Summary of the Invention

[0005] The various aspects of the invention are as described in the independent claims, and optional features are as described in the dependent claims. The various aspects of the invention can be combined with each other, and features of one aspect can be applied to other aspects.

[0006] In a first aspect, a hydroponic system for irrigating crops is provided, wherein the system includes a planting frame, and wherein the planting frame includes a rotating portion, the rotating portion further including a helical conduit. The helical conduit includes a plurality of holes for receiving the planted crop. The helical conduit is configured to receive a fluid, such as a nutrient-rich fluid, and the helical conduit further includes openings for receiving the nutrient-rich fluid in a helix, such that in use, rotation of the helical conduit supplies the nutrient-rich fluid around the conduit toward the center of the helix and through the plurality of holes for receiving the planted crop. In some examples, using a helical conduit to supply fluid so that the fluid flows through the plurality of holes for receiving the planted crop can eliminate the need for a fluid pumping component in the hydroponic system. This can be advantageous because fluid pumping components can be expensive and energy-intensive. In some examples, the shape of the helical conduit and the plurality of holes for receiving the planted crop can increase the capacity for receiving the planted crop compared to a cylindrical roller configuration having the same diameter and depth.

[0007] In some examples, the plurality of holes for receiving the planted crop are arranged on the face of the conduit facing the center of the helix, such that the planted crop grows concentrically inward toward the center of the helix. This configuration allows the planted crop to experience a net zero-gravity environment during rotation, which can increase the growth rate of the planted crop. This configuration also reduces the volume of nutrient-rich fluid lost through the holes due to gravity during use, compared to another configuration where the plurality of holes for receiving the planted crop are arranged on the face of the conduit facing outward and perpendicular to the center of the helix. Other configurations are also possible, for example, in which the plurality of holes for receiving the planted crop are arranged on the outward-facing face of the conduit perpendicular to the center of the helix.

[0008] In some examples, the plurality of holes for receiving the planted crop are evenly spaced around the spiral. In some examples, the spacing between the holes may be determined by the planted crop, for example by the type of crop, or by the growing space required by the type of crop.

[0009] In some examples, the planting frame also includes a stationary portion for supporting the rotating portion.

[0010] In some examples, the spiral conduit is supported above the fluid pool via the stationary portion of the planting frame. In use, the opening in the spiral for receiving the nutrient-rich fluid can be configured to scoop fluid from the fluid pool as the spiral rotates. In some examples, using the spiral conduit to collect fluid from the fluid pool during rotation eliminates the need for a fluid pumping component in the hydroponic system. This can be advantageous because fluid pumping components can be expensive and energy-intensive.

[0011] In some examples, the opening for receiving the nutrient-rich fluid includes a funnel-shaped element. The funnel-shaped element can increase the volume of the nutrient-rich fluid received into the helical conduit. The funnel-shaped element can extend beyond the periphery of the helical conduit, allowing it to collect the nutrient-rich fluid from deeper within the fluid pool.

[0012] In some examples, the center of the spiral is connected to a flow path for returning fluid to the fluid pool. By recirculating the fluid back to the fluid pool, water consumption and water waste associated with hydroponics can be reduced. Reduced water consumption results in a more sustainable and resource-efficient hydroponic system.

[0013] In some examples, the fluid pool may include a valve system coupled to the fluid supply unit, wherein the valves are configured to detect when the fluid level is low and replenish the fluid pool.

[0014] In some examples, nutrients can be dripped into the fluid pool from a central storage unit. The flow rate of nutrients into the fluid pool can be manually controlled or automatically adjusted. This allows the fluid (e.g., water) in the fluid pool to be maintained at the desired nutrient level. The required nutrient level can be determined by the optimal level for crop cultivation or by the farmer, for example, depending on their affordability.

[0015] In some examples, the spiral is an Archimedean spiral.

[0016] In some examples, the planting frame may include multiple conduits arranged in multiple spirals. The multiple spiral conduits may be arranged to spiral in the same direction (e.g., clockwise or counterclockwise) so that fluid can be supplied through the multiple spiral conduits during use. For example, the planting frame may include two spiral conduits. This can improve the space utilization of the hydroponic system and increase the number of crops grown in each planting frame.

[0017] In some examples, the implantation frame includes a pair of conduits arranged as a pair of helices, wherein the first helix is ​​offset by 180 degrees relative to the second helix on the axis of rotation, such that the opening for receiving the nutrient-rich fluid is located on the side of the first helix opposite to the opening of the second helix for receiving the nutrient-rich fluid.

[0018] In some examples, the rotating portion of the planting frame can be manually actuated. For example, the rotating portion can rotate intermittently throughout the rotation cycle. This can be advantageous by reducing the energy consumption of the hydroponic system. In some examples, the rotating portion may also include a handle for manual actuation. In some examples, the planting frame may also include at least one mark indicating the rotation position, which can help the user to even out the rotation cycle. In some examples, the hydroponic system can be entirely manually actuated, which may be advantageous for use in resource-constrained environments, including developing countries.

[0019] In other examples, the rotating portion of the planting frame can be actuated by a motor. This is advantageous compared to manual actuation by reducing the labor required. In some examples, the rotating portion can rotate intermittently over a period of time throughout the rotation cycle; in other examples, the rotating portion can rotate continuously. In some examples, the hydroponic system may also include renewable power generation components, such as solar panels, to power the hydroponic system (including the motor).

[0020] Changing the rotation speed will change the amount of water / nutrients reaching the planted crops, as well as the aeration rate.

[0021] In some examples of automation, multiple operating modes can exist. For instance, different operating modes may require a controller to use motors to achieve different rotation speeds. For example, different rotation speeds can be used for different crops (e.g., based on the crop variety) depending on the desired rate of water / nutrient delivery and / or aeration. Different rotation speeds can also be used for harvesting, such that during use, the rotation speed is adjusted to the picking speed during harvesting. This allows the user or robotic harvester to harvest the crop at approximately the same height. Cleaning operating modes can also utilize different rotation speeds, allowing fluid to be supplied through conduits to flush out residual dirt and debris. Customized speeds determined by the user / farm can also be implemented and / or stored in memory coupled to the controller.

[0022] In some examples, the hydroponic system may also include components for blowing air (e.g., hot air) through spiral conduits. During use, in cleaning operation mode, air can be blown through the spiral conduits to remove dried roots and debris from the conduits.

[0023] In some examples, the hydroponic system may include artificial lighting, such as LED lighting. This can be advantageous for use in locations where natural light is insufficient for optimal crop growth, including indoor locations. Artificial lighting can also accelerate crop growth by providing extended periods of illumination compared to natural light. In some examples, the artificial lighting can be controlled according to a predetermined schedule. In some examples, the artificial lighting can be controlled in response to a signal from a light sensor when a natural light level is detected to be above and / or below a predetermined threshold. In some examples, the artificial lighting can be controlled via a central controller, which in some examples can control both the artificial lighting and the motor. In some examples, the artificial lighting can be tuned to selected light wavelengths configured to optimize crop health and growth rate, such as, but not limited to, enhancing blue wavelengths (including 430 nm to 450 nm) and / or red wavelengths (including 640 nm to 680 nm). In some examples, LED lighting can also emit light in infrared wavelengths, such as wavelengths in the range of 700nm to 1mm, 700nm to 1400nm, or 700nm to 760nm.

[0024] In some examples, the strip light source can be held in a fixed position adjacent to the spiral conduit, wherein the length of the strip light source is determined by the diameter of the spiral. This configuration can be advantageous because it uses a single fixed light source adjacent to the rotating spiral conduit, thus reducing the amount of illumination required to provide light energy to the entire spiral conduit, and thereby reducing energy consumption. In other examples, a pair of strip lights located on opposite sides of the planting frame can be used.

[0025] In some examples, a strip light source may be arranged on at least a portion of the face of the conduit away from the center of the spiral. In this configuration, the strip light can be arranged directly opposite the planted crop located on the adjacent outer ring of the spiral conduit. This configuration can be advantageous by providing a more uniform illumination distribution to the planted crop throughout the spiral conduit. In some examples, an additional light source may be arranged at the center of the spiral, configured to provide illumination to the planted crop in the plurality of holes 108 located on the innermost ring of the spiral conduit 106A.

[0026] In some examples, the hydroponic system includes a track system that supports multiple planting frames. Using multiple planting frames can potentially improve space utilization. The planting frames can be moved along the track system to adjust their spacing. This ability to adjust spacing is advantageous because it allows the planting frames to be compressed during growth to improve space utilization; however, it also makes the planting frames easy to move and separate for easy inspection, maintenance, and harvesting of the crops.

[0027] In some examples, the hydroponic system further includes a plurality of reusable planting plugs as detailed in a second aspect of the invention, wherein each of the plurality of reusable planting plugs is configured to fit within the plurality of holes on the at least one helical conduit for receiving the planted crop.

[0028] In a second aspect, a reusable planting plug for use in a hydroponic system is provided. Reusable planting plugs may be advantageous compared to disposable and / or biodegradable planting plugs because they provide a sustainable solution and reduce waste. According to the reusable planting plug of the invention, at least a portion of the planting plug is flexible, and the reusable planting plug includes a first surface, a second surface, and at least one hole extending through the first and second surfaces for receiving planted material. The planting plug also includes a plurality of prongs coupled to the second surface. The planting plug has a first configuration and a second configuration, wherein, relative to the second configuration, in the first configuration, the plurality of prongs are aggregated together; and relative to the first configuration, in the second configuration, the plurality of prongs are separated.

[0029] In some examples, the crop may be a seed. In some examples, the crop may be a seed embedded in biodegradable tissue. In some examples, the crop may include other forms of plants, such as germinating seedlings.

[0030] In some examples, the first configuration allows the planted crop to be gripped and held by the prongs. Therefore, in some examples, a growing medium is not required. This reduces the amount of materials needed for planting, thereby reducing waste, increasing sustainability, and lowering costs.

[0031] Furthermore, the first configuration allows fluid flowing through the planting plug to be retained on the prongs by surface tension, thereby delivering fluid and nutrients to the planted crop. This can be particularly advantageous before the planted crop has taken root.

[0032] In some examples, crops can be propagated and harvested in a single planting plug without the use of other processes.

[0033] In some examples, the second configuration allows the planting plug to separate and / or break off the roots of the planted crop. In some examples, this facilitates easy removal of the roots after harvesting the planted crop and cleaning of the reusable planting plug.

[0034] In some examples, in the second configuration, the multiple pins can be configured to form a radial arrangement such that the pins are separate relative to the first configuration. In some examples, the pins can be configured to extend radially around the hole. In some examples, the radial arrangement of the pins in the second configuration can be arranged such that the multiple pins are configured to lie in the same plane as the hole, for example, such that the implant plug can be configured to lie flat in the second configuration.

[0035] In some examples, in the first configuration, the implant plug is biased to form a dome, and in the second configuration, the implant plug is biased to form an inverted dome opposite to the first configuration. In some examples, the first surface and the second surface form a diaphragm, wherein in the first configuration, the diaphragm is biased to form a dome, and in the second configuration, the diaphragm is biased to form an inverted dome opposite to the first configuration.

[0036] In some examples, in the first configuration, the implant plug is biased to form a conical shape, such as a truncated cone; and in the second configuration, the implant plug is biased to form an inverted conical shape opposite to the conical shape of the first configuration, such as a truncated cone. In some examples, the first surface and the second surface form a diaphragm, wherein in the first configuration, the diaphragm is biased to form a conical shape, such as a truncated cone; and in the second configuration, the diaphragm is biased to form an inverted conical shape opposite to the first configuration.

[0037] Those skilled in the art will understand that, in other examples, the first and second surfaces may form a diaphragm, wherein the diaphragm is configured to be biased to form any other suitable shape. Preferably, the shape of the diaphragm in the second configuration is inverted relative to the shape of the diaphragm in the first configuration.

[0038] In some examples, switching the implant plug between a first configuration and a second configuration may include inverting the septum in the second configuration relative to the first configuration. For example, such that in the first configuration, the first surface may face outward and the second surface may face inward; and in the second configuration, the first surface may face inward and the second surface may face outward; and vice versa.

[0039] The holes extending through the first and second surfaces in the planting plug can be configured to allow the planted crop to grow through the holes. In some examples, the holes are cross-shaped, such as cross slits. This allows the slits to widen as the planted crop grows. In other examples, the holes can be circular or any other suitable shape.

[0040] In some examples, the plurality of pins coupled to the second surface includes at least four flexible pins. In some examples, the plurality of pins coupled to the second surface may include twenty-eight flexible pins; however, those skilled in the art will understand that any other number of pins may be used. In some examples, the pins 904 may be equally spaced along the second surface, optionally wherein the pins are arranged concentrically or circumferentially around the hole.

[0041] In some examples, each pin portion includes a proximal end and a distal end, wherein the proximal end is coupled to the second surface and the distal end extends away from the second surface. In some examples, each pin portion may have a generally tapered shape, for example, wherein the cross-sectional area of ​​each pin portion at the proximal end is greater than the cross-sectional area at the distal end.

[0042] In some examples, at least a portion of the implant plug is made of rubber.

[0043] In some examples, the planting plug also includes a gripping portion located on the first surface. This can facilitate the conversion between the first and second configurations, for example, when the planting plug is located within a hole in a hydroponic system. In some examples, the gripping portion on the first surface may include at least one prong.

[0044] In some examples, the planting plug also includes a resilient portion. The resilient portion is sized to allow fitting into the holes in the hydroponic system for receiving the planted material. In some examples, the resilient portion can be configured to engage with the edge of the holes in the hydroponic system for receiving the planted material. In some examples, the resilient portion can be configured to fit into the holes in the hydroponic system for receiving the planted material via a friction fit. In use, as the roots of the planted material grow within the guide tubes, the planting plug can be further secured within the holes of the hydroponic system.

[0045] In some examples, the resilient portion may include a flange. In some examples, the diaphragm may include a flange. In some examples, the flange may be configured to engage with the edge of a hole in a hydroponic system for receiving plant material. In some examples, the flange may be used to secure and / or seal a planting plug within a hole in a hydroponic system for receiving plant material. Attached Figure Description

[0061] Figure 1 An exemplary hydroponic system including a planting frame 100 is shown, which further includes a rotating portion 102 and a stationary portion 104. In this example, the rotating portion 102 includes a circular frame 103 with two supports 105 attached to the periphery of the circular frame 103 and spanning the diameter of the frame 103, such that the supports 105 divide the circular frame 103 into four equal quadrants. In this example, the circular frame 103 is made of steel; in other examples, other materials including other metals or plastics may be used. The circular frame 103 also includes an axis 116 disposed at the center of the circular frame 103 and attached to the dividing points of the supports 105. The axis 116 is perpendicular to the plane of the circular frame 103.

[0062] In this example, the stationary portion 104 comprises a pair of identical triangular frames 107, which are joined together by at least one horizontal support 111. In this example, the stationary portion 104 is made of steel; in other examples, other materials, including other metals or plastics, may be used. The triangular frames 107 are oriented such that they have flat edges at the bottom and vertices vertically displaced from the center of the bottom edge. The length of the bottom of the triangular frame 107 is approximately equal to the diameter of the rotating portion 102, but preferably slightly less than the diameter of the rotating portion 102. The maximum height of the triangular frame 107 at its vertices must be greater than the radius of the rotating portion 102; in this example, the maximum height of the triangular frame 107 at its vertices is slightly greater than the radius of the rotating portion 102. A circular frame 103 is located between the pair of triangular frames 107, and the circular frame 103 is parallel to the plane of the triangular frames 107. In the example shown, an axis 116 is positioned perpendicular to the pair of triangular frames 107 between the vertices of the triangular frames 107 in the stationary portion 104. The outer end of shaft 116 is received in a hole at the vertex of each of the two triangular frames 107. Shaft 116 can be disposed in a bearing at each vertex of the two triangular frames 107.

[0063] Figure 1 The hydroponic system shown also includes a fluid pool 112. The fluid pool 112 is positioned at the bottom of the planting frame 100, below the rotating portion 102, between the triangular frames 107. In some examples, the fluid pool 112 is supported by multiple vertical supports between the triangular frames of the stationary portion 104. In this example, the length of the fluid pool 112 is approximately equal to the length of the base of the triangular frames 107. In this example, the width of the fluid pool 112 is equal to the spacing between the triangular frames 107. The depth of the fluid pool 112 is determined by the height difference between the height of the axis 116 and the radius of the rotating portion 102, wherein the height of the axis 116 is determined by the height of the triangular frames 107 at their vertices.

[0064] The rotating portion 102 also includes a pair of conduits 106A and 106B, both arranged in a helical configuration. In other examples, the rotating portion 102 may include a single conduit or two or more conduits. In this example, conduits 106A and 106B are identical. In this example, conduits 106A and 106B are Archimedean spirals. This pair of helical conduits 106A and 106B are arranged on opposite faces of the circular frame 103. Conduits 106A and 106B are attached to the circular frame 103 along at least one of the supports 105 spanning the diameter of the circular frame 103. Figure 4A and Figure 4B The exemplary attachment arrangement is shown in more detail below.

[0065] Helical conduits 106A and 106B include a plurality of holes 108 arranged on the surface of the conduit facing the helix center. In some examples, helical conduits 106A and 106B may be made of HDPE or polypropylene. In other examples, other materials, such as other plastics or metals, may be used. In some examples, helical conduits 106A and 106B may be corrugated. In the example shown, the internal cross-sectional diameter of conduits 106A and 106B is 100 mm. In other examples, conduits of other sizes may be used, for example, where the conduit size is configured to allow the planted crop to have a specific root length, or where the conduit size is configured to perform a specific function to enable fluid passage, including determining the volume of fluid delivered to the planted crop. In this example, the helical diameter of helical conduits 106A and 106B is 3 meters. In other examples, helical configurations with different diameters may be used. For example, the diameter of the helical configuration may preferably fall within, but is not limited to, the range of 1 meter to 10 meters. In some examples, the maximum diameter of the spiral configuration can be 5 meters, allowing crops to still be harvested manually from the ground.

[0066] In this example, the outer ends of each spiral conduit 106A and 106B include openings 109A and 109B, respectively. Openings 109A and 109B are arranged parallel to the cross-section of the conduit on the end face of each of the conduits 106A and 106B. In this example, openings 109A and 109B span the diameter of conduits 106A and 106B, such that conduits 106A and 106B are end-open at the outermost ends of the spiral. A funnel-shaped member 110 is optionally attached to the spiral conduits 106A and 106B at openings 109A and 109B. In the example shown, the funnel-shaped member 110 has a tapered shape.

[0067] In this example, the inner end of the spiral conduit 106 located at the center of the spiral is connected to the flow path 120 for returning fluid to the fluid pool 112. Figure 6A and Figure 6B An exemplary flow path is shown in more detail below.

[0068] exist Figure 1In the example shown, motor 114 is optionally mounted on a horizontal support 111 located between a pair of triangular frames 107 of the stationary portion 104 of the planting frame 100. Motor 114 is mounted in the middle of support 111, aligned with the circular frame 103 of the rotating portion 102. In the example shown, motor 114 is attached to support 111 via a two-part motor housing 115. The first part of motor housing 115 is secured to support 111 as support 111 passes through a hole in the first part of motor housing 115. The first part of motor housing 115 also includes a receiving slot. At least a portion of motor 114 is fitted into the receiving slot within the first part of motor housing 115. The second part of motor housing 115 is a bracket attached to the first part of motor housing 115, opposite the receiving slot and adjacent to motor 114. The second part of motor housing 115 can be attached to the first part of motor housing 115 by bolts or other fastening components such as screws. The second part of the motor housing 115 is configured to secure the motor 114 within the receiving portion of the first part of the motor housing 115.

[0069] Motor 114 is arranged to contact the periphery of the circular frame 103 of the rotating portion 102. In the example shown, motor 114 includes a pair of identical wheel-shaped members arranged on opposite sides of the circular frame 103 and in contact with the periphery of the circular frame 103.

[0070] The rotating portion 102 of the planting frame 100 is configured to rotate, causing the spiral conduits 106A and 106B to also rotate.

[0071] The stationary portion 104 is arranged to support the rotating portion 102 above the fluid pool 112, such that the outer end of the conduit 106, including the opening 109, is configured to be at least partially submerged in the fluid within the fluid pool 112 during rotation. The stationary portion 104 is configured to support the rotating portion 102 about an axis 116, allowing the rotating portion 102, including the helical conduit 106, to rotate freely. The motor 114 is configured to drive the rotating portion 102 to rotate clockwise or counterclockwise. In other examples, the rotating portion 102 can be rotated manually. In the example shown, a pair of wheel-like members of the motor 114 are configured to rotate relative to each other in opposite directions while contacting the circular frame 103 to drive the rotating portion 102 to rotate. The motor 114 can be configured to operate at a number of different rotational speeds. The number of different rotational speeds can be attributed to different operating modes. For example, different operating modes may be used for different crops (e.g., based on the type of crop) depending on the desired rate of water / nutrient delivery and / or aeration. Different operating modes can also be used for harvesting, allowing the rotation speed to be adjusted to the picking speed during harvesting. This enables the user or robotic harvester to harvest crops at approximately the same height. A cleaning operating mode can also utilize different rotation speeds, allowing fluid to be supplied through conduits to flush away residual dirt and debris. Customized rotation speeds determined by the user / farm can also be implemented and / or stored in memory coupled to the motor controller.

[0072] like Figure 2 As shown, each of the plurality of holes 108 is configured to receive a plant 200. In the example shown, each of the plurality of holes 108 is configured to receive a reusable planting plug 900, wherein the reusable planting plug 900 is configured to receive the plant 200. The planting plug 900 is configured to grip the plant 200 to ensure that the plant 200 is secured and does not fall out of the spiral conduits 106A and 106B during rotation. Figure 9A and Figure 9B An exemplary, reusable planting plug 900 is shown in more detail below. Those skilled in the art will understand that the plurality of holes 108 may additionally or alternatively be configured to receive the reusable planting plug 1100 or any other suitable reusable planting plug, wherein the reusable planting plug 1100 is configured to receive the planted crop 200. The planting plug 1100 may also be configured to grip the planted crop 200 to ensure that the planted crop 200 is secured and does not fall out of the spiral conduits 106A and 106B during rotation. Figures 11A to 11D An exemplary, reusable implant plug 1100 is shown in more detail below.

[0073] like Figure 2 As shown, the stems of the planted crop 200 grow concentrically inward toward the center of the spiral. This is likely driven by phototropism. The roots of the planted crop 200 grow concentrically outward and enter the spiral vascular bundle 106A.

[0074] exist Figure 2 In the example shown, the spacing between the holes 108 is configured to maximize the number of holes 108 along the conduits 106A and 106B, thereby maximizing the space utilization for planting the crop 200 while also providing the appropriate amount of space required for the growth of each crop species between the holes 108. In some examples, the spacing between the holes 108 may be determined by the optimal growth space required by the crop species.

[0075] Similarly, the distance between the coils of spiral vascular bundles 106A and 106B can be determined by the optimal growing space required by the crop species being grown. For example, crops with tall stems may require a greater distance between the coils of spiral vascular bundles 106A and 106B compared to crops with shorter stems.

[0076] Spiral conduits 106A and 106B are configured to receive fluid through openings 109A and 109B and to deliver fluid to implant plugs 900 within a plurality of orifices 108.

[0077] The funnel 110 is configured to increase the volume of fluid received in the spiral conduit 106. For example, the funnel 110 may be configured to extend beyond the periphery of the spiral conduits 106A and 106B, so that the funnel 110 can collect fluid from a deeper part of the fluid pool 112 than is done by the openings 109 in the spiral conduits 106A and 106B alone. Figure 5 An exemplary bucket-shaped member 110 is shown in more detail below. In this example, the bucket-shaped member 110 is configured to be fitted into openings 109A and 109B by friction fit. In other examples, other attachment methods, such as threads, may be used.

[0078] In use, motor 114 causes the pair of motor wheels to rotate in opposite directions. The contact between the pair of rotating wheels of motor 114 and the circular frame 103 applies rotational force to the circular frame 102. This causes the periphery of the circular frame 103 to pass through the pair of wheels, thereby driving the rotational actuation of the rotating part 102.

[0079] In use, the rotation of the rotating part 102 causes the bucket-shaped piece 110 in the openings 109A and 109B at the ends of the spiral conduits 106A and 106B to scoop fluid from the fluid pool 112, and to transport the fluid around the conduits 106A and 106B toward the center of the spiral and through the multiple holes 108 for receiving the planted crops.

[0080] In the example where the planting plug 900 is disposed within multiple holes 108, some of the fluid passing through can be retained on the planting plug 900 by surface tension. During rotation, the retained fluid can travel along the planting plug 900 to the planted crop 200. This can be particularly beneficial before the planted crop 200 has developed a well-established root system. Figure 9A and Figure 9B An exemplary planting plug 900 is described in more detail below. Those skilled in the art will also understand that, in the example where the planting plug 1100 is disposed within a plurality of holes 108, some of the fluid passing through can be retained on the planting plug 1100 by surface tension. During rotation, the retained fluid can travel along the planting plug 1100 to the planted crop 200. This can be particularly advantageous before the planted crop 200 has developed a well-established root system. Figures 11A to 11D An exemplary, reusable implant plug 1100 is shown in more detail below.

[0081] In use, when the diameter of the spiral configuration exceeds 5 meters, ladders, vehicle-mounted lifting platforms, or robotic automation may be required to harvest the planted crops. Figure 3 Shown from different angles Figure 1 An exemplary hydroponic system is described. In this example, the first helix 106A is offset by 180 degrees relative to the second helix 106B on the axis of rotation, such that the opening 109A for receiving fluid is located on the side of the first helix 106A opposite to the opening 109B of the second helix 106B for receiving fluid. In use, the first helix collects fluid from the fluid pool 112 during rotation, and then the second helix collects fluid from the fluid pool 112 after half a rotation cycle. This can help stabilize the planting frame 100. In addition to staggering the helical conduits 106A and 106B, the planting frame 100 is otherwise symmetrical about the central circular frame 103 of the rotating portion 102; for example, the conduits 106A and 106B have separate but identical flow paths 120 at the inner ends of the helices to allow residual fluid to return to the pool 112. Figure 6A and Figure 6B An exemplary flow path 120 is shown in more detail below.

[0082] exist Figure 4A and Figure 4BIn the example shown, the pair of helical conduits 106A and 106B are connected to the rotating portion 102 of the implantation frame via a bracket 402. Because the first helical conduit 106A is offset by 180 degrees relative to the second helical conduit 106B, the brackets 402 have an interlaced configuration. In this example, conduits 106A and 106B are configured to be clamped into the Y-shaped bracket 402 using a friction fit. In other examples, the conduits may be attached to the bracket using additional fasteners such as bolts or screws.

[0083] exist Figure 5 In the example shown, a rotating portion 102, including at least one helical conduit 106, is arranged above a fluid pool 112 such that the outer end of the conduit 106, including an opening 109, is configured to be at least partially submerged in fluid within the fluid pool 112 during rotation. In use, the opening 109 for receiving nutrient-rich fluid into the helical conduit 106 is configured to scoop fluid from the fluid pool 112 as the helical conduit 106A rotates. In this example, the opening 109 for receiving nutrient-rich fluid includes a funnel-shaped member 110. The funnel-shaped member 110 can increase the volume of nutrient-rich fluid received into the helical conduit 106. The funnel-shaped member 110 can extend beyond the periphery of the helical conduit 106, which allows the funnel-shaped member to collect nutrient-rich fluid from deeper within the fluid pool 112.

[0084] In some examples, the fluid in fluid pool 112 can be automatically replenished from a central fluid supply unit. In some examples, fluid pool 112 may include a valve system coupled to the fluid supply unit, wherein the valve is configured to detect when the fluid level is low and replenish the fluid in the fluid pool. In other examples, the fluid in fluid pool 112 can be manually replenished.

[0085] In some examples, the fluid pool 112 can be enriched with nutrients by dripping them from a central reservoir. The nutrient-rich fluid can be configured to improve the health and growth rate of the grown crops. The flow rate of nutrients entering the fluid pool can be manually controlled or automatically adjusted. This allows the fluid in the fluid pool 112 to be maintained at the desired nutrient level. In other examples, nutrients can be manually replenished by replenishing the fluid within the fluid pool 112.

[0086] Figure 6A and Figure 6BAn exemplary flow path 120 for returning fluid from the inner end of a helical conduit 106 to a fluid pool 112 is shown. The flow path arrangement includes a connecting conduit 122 that connects the inner end of the helical conduit 106 to a container 118. In the example shown, the connecting conduit 122 includes three sections: 122A, 122B, and 122C, arranged perpendicularly to each other. A first end of the connecting conduit 122 is attached to the inner end of the helical conduit 106, and a second end of the connecting conduit 122 is connected to a receiving portion of the container 118. The connecting conduit can be attached to the inner end of the helical conduit 106 using a friction fit.

[0087] Container 118 is attached to the vertex of the triangular frame 107 of the stationary portion 104 of the planting frame 100. In the example shown, container 118 has a cylindrical shape, wherein the receiving portion of container 118 is arranged facing the helical conduit 106 parallel to the rotating portion 102 of the planting frame 100. Container 118 has a hole 602 on the opposite surface of the receiving portion. Drainage pipe 121 is connected to the bottom of container 118. Drainage pipe 121 connects container 118 to fluid pool 112.

[0088] A first section 122A of the connecting conduit 122 is configured to attach to the inner end of the spiral conduit 106. The first section 122A is configured to receive residual fluid from the inner end of the spiral conduit 106. A second section 122B is configured to connect the first section 122A and the third section 122C of the connecting conduit 122, and is configured to receive residual fluid from the first section 122A of the connecting conduit 122 and deliver the fluid to the third section 122C of the connecting conduit 122. The third section 122C is configured to connect to the receiving portion of the container 118. The third section 122C is configured to receive fluid from the second section 122B and deliver the fluid to the container 118.

[0089] The receiving portion of container 118 is configured to receive fluid from the third section 122C of the connecting conduit 122. Container 118 is configured to deliver the fluid to downpipe 121. The central hole 602 in container 118 is configured to receive the shaft 116 of rotating portion 102.

[0090] The drain pipe 121 is configured to receive fluid from container 118 and is also configured to deliver the fluid to fluid pool 112. This completes the flow path 120 for returning the fluid to fluid pool 112.

[0091] By recirculating the fluid back into the fluid pool 112, water consumption and water waste caused by the hydroponic system can be reduced. Reduced water consumption results in a more sustainable hydroponic system that consumes fewer resources.

[0092] During use, as the spiral conduit 106 rotates, residual fluid is supplied to the inner end of the spiral conduit 106 and enters the connecting conduit 122. During rotation, the connecting conduit 122 follows a circular path, wherein the third segment 122C of the connecting conduit 122 circumferentially surrounds the inner region of the container 118. The residual fluid enters the container 118 through the connecting conduit 122. The fluid then drains from the container 118 into the fluid pool 112 via the drain pipe 121. Figure 7A An exemplary lighting configuration is shown, comprising a pair of strip light sources 700 held adjacent to a pair of helical conduits 106A and 106B, wherein the length of the strip light source 700 is dependent on the diameter of the helical conduits 106A and 106B. The length of the strip light source 700 is significantly greater than its width and depth dimensions. The light sources 700 are oriented toward the helical conduits 106A and 106B. Each strip light 700 within the pair of strip light sources is arranged on opposite sides of the planting frame 100. The strip light source 700 is fixed to the stationary portion 104 of the planting frame 100. In this example, the strip light source 700 is attached at the apex of the triangular frame 107 and is height-aligned with axis 116. The strip light source 700 extends horizontally, and its length is equal to the diameter of the helical conduits 106A and 106B. In other examples, the strip light source 700 may have alternative orientations, but is preferably kept aligned with axis 116. In this example, the strip light source 700 is an LED light source. In other examples, other types of light sources may be used. In this example, the LED lighting emits wavelengths spanning the visible light spectrum. The LED lighting can be further tuned for selected light wavelengths configured to optimize the health and growth rate of the grown crop, for example, enhancing blue wavelengths including 430 nm to 450 nm and / or red wavelengths including 640 nm to 680 nm. In some examples, the LED lighting may also emit infrared wavelengths. In other examples, a single strip light source may be used.

[0093] Figure 7BAn alternative exemplary lighting configuration is shown, comprising a flexible strip light source 702 disposed on at least a portion of the face of a spiral conduit 106A facing away from the spiral center. In this configuration, the strip light 702 is arranged so that its position is directly opposite a plurality of holes 108 located on an adjacent outer ring of the spiral conduit 106A. The strip light 702 is configured to begin on the face of a second ring of the spiral conduit 106A facing away from the spiral center, opposite to the outermost hole 108 located on the outermost ring of the spiral conduit 106A. The strip light 702 is configured to terminate on the face of the innermost ring of the spiral conduit 106A facing away from the spiral center. In use, the plurality of holes 108 are configured to receive planted crops such that the light source 702 is disposed directly above the planted crops. In some examples, an additional light source may be disposed at the center of the spiral, configured to provide illumination to the planted crops in the plurality of holes 108 located on the innermost ring of the spiral conduit 106A. In this example, the strip light source 702 is an LED light source. In other examples, other types of light sources may be used. In this example, the LED lighting emits wavelengths spanning the visible light spectrum. The LED lighting can be further tuned for selected light wavelengths configured to optimize the health and growth rate of the grown crop, for example, enhancing blue wavelengths including 430 nm to 450 nm and / or red wavelengths including 640 nm to 680 nm. In some examples, the LED lighting may also emit infrared wavelengths.

[0094] exist Figure 8A and Figure 8B In the example shown, the hydroponic system 800 includes a track assembly 802 that supports multiple planting frames 100. The multiple planting frames 100 preferably have the same dimensions; however, in some examples, the multiple planting frames 100 may have different helical conduits 106 for different crops. The tracks 802 are oriented perpendicular to the rotating portions 102 of the planting frames 100. The tracks 802 are configured to be spaced apart based on the width of the base of the triangular frame 107 of the stationary portion 104 of the planting frames 100, parallel to the rotating portions 102 of the planting frames 100. The length of the tracks 802 is determined by the depth of the multiple planting frames 100.

[0095] Multiple planting frames 100 can be moved on the track assembly 802 to adjust the spacing between them. Therefore, the length of the track 802 can be configured to accommodate at least a combined depth of multiple planting frames 100, including additional length portions to facilitate separating at least one planting frame 100 from multiple adjacent planting frames 100. This ability to adjust the spacing can be advantageous because it allows the planting frames 100 to be compressed together during growth to improve space utilization, while also enabling easy movement and separation of the planting frames 100 for inspection, maintenance, and harvesting of the crops. For example, in use, multiple planting frames 100 can be separated during the preparation of the hydroponic system (e.g., during the placement of planting plugs 900 or 1100 into holes 108 to receive the crops in the hydroponic planting frames 100) for easy access by the farmer. During the growth stage of the crops, the multiple planting frames 100 can be moved closer together so that the rotating portions 102 of the multiple planting frames 100 are adjacent to each other. This can improve space utilization during growth. Multiple planting frames 100 can then be separated again to facilitate easy access to each planting frame during harvesting. In the example shown, the multiple planting frames 100 can be separated sequentially, such that one planting frame 100 is separated from the multiple planting frames 100 adjacent to each other at a time. This allows for a shorter required track 802 compared to separating all the multiple planting frames 100 simultaneously, thereby improving space utilization.

[0096] Figure 8C A detailed example is shown in which multiple planting frames 100 can be moved on a track assembly 802 by a set of wheels 804 attached to a stationary portion 104 of the planting frame. In the example shown, the set of wheels includes three wheels 804. The wheels 804 can be attached to the bottom of a pair of triangular frames 107 of the stationary portion 104 of the planting frame 100. The wheels 804 can also be attached to vertical supports that support and connect the pair of triangular frames 107 of the stationary portion 104 of the planting frame 100 together.

[0097] Reusable planting plugs

[0098] Figure 9A and Figure 9B An exemplary, reusable implant plug 900 is shown. The implant plug 900 includes a first surface 902A and a second surface 902B opposite to the first surface 902A, the first surface 902A and the second surface 902B forming a flexible diaphragm 902.

[0099] The planting plug 900 also includes a hole 906 centrally disposed in the diaphragm 902, the hole 906 extending through the first surface 902A and the second surface 902B. In the example shown, the hole 906 is a cross-shaped slit. This allows the hole slit 906 to widen as the planted crop grows. In other examples, other slit or hole shapes may be used.

[0100] Multiple pin portions 904 extend from the second surface 902B of the diaphragm 902. In the example shown, there are four pin portions 904. In other examples, there may be more or fewer pin portions 904. In this example, the pin portions 904 are equally spaced around the hole 906. In other examples, the pin portions 904 may have different arrangements.

[0101] The implant plug 900 also includes a resilient portion 908 surrounding the septum 902. Figure 9A and Figure 9B In the example shown, the elastic portion 908 has a circular cross-section. In other examples, the elastic portion 908 may have a cross-section of different shapes, such as, but not limited to, a square, rectangular, or triangular cross-section. In this example, the diaphragm 902 is attached to the lower edge of the elastic portion 908 in an aligned manner such that, in a first configuration, the diaphragm extends through the elastic portion 908, while in a second configuration, the diaphragm extends outward from the elastic portion 908. However, in other examples, the diaphragm 902 may be attached at any point within the inner periphery of the elastic portion 908. The elastic portion 908 may optionally include a flange 910. In this example, the flange 910 is disposed at the upper edge of the elastic portion 908, which is opposite the edge of the elastic portion 908 to which the diaphragm 902 is attached. However, in some examples, the flange 910 may be disposed at the lower edge of the elastic portion 908. In some examples, the elastic portion may have a flange 910 disposed at the outer edge of the elastic portion 908 and a second flange disposed at the lower edge of the elastic portion 908.

[0102] In some examples, the implant plug 900 is made of rubber.

[0103] Figure 9A An exemplary implant plug 900 is shown arranged in a first configuration, wherein, relative to a second configuration, a diaphragm 902 is biased to form a dome, and a plurality of prongs 904 are clustered together.

[0104] Figure 9B An exemplary implant plug 900 arranged in a second configuration is shown, wherein, relative to the first configuration, the diaphragm 902 is biased to form an inverted dome opposite to the dome of the first configuration, and a plurality of prongs 904 are separated.

[0105] The cross-section of the elastic part 908 can be configured to be formed by a hydroponic system (such as...) Figures 1 to 8C The planting plug 900 is received in a receiving hole in any of the hydroponic systems shown. In some examples, the resilient portion 908 may be configured to engage with the periphery of the receiving hole in the hydroponic system via a friction fit. In some examples, the flange 910 may be configured to secure and / or seal the planting plug 900 within the receiving hole in the hydroponic system, for example, by engaging with the edge of the hole. For example, when the flange 910 is positioned at the upper edge of the resilient portion 908, the flange 910 may prevent the planting plug from passing through the receiving hole and falling into the conduit of the hydroponic system. When the flange 910 is positioned at the lower edge of the resilient portion 908, the flange 910 may prevent the planting plug from falling out of the receiving hole in the hydroponic system during rotation.

[0106] In use, the first configuration is set to grip the planted crop between the prongs 904. This secures the planted crop in place within the planting plug 900.

[0107] As the planted crop grows, the root system extends along the cutting 904. When in situ in a hydroponic system, this allows the roots to extend into, for example, the nutrient and fluid supply sections located within the tubing.

[0108] Before the root system develops, the planted crop can receive fluid from the prongs 904, which retains some of the passing fluid through surface tension. During rotation, the retained fluid can travel along the prongs 904 to the planted crop.

[0109] The stem of the planted crop grows in the opposite direction to the root system, and as the stem grows, it protrudes through the aperture 906. This is likely driven by the plant's phototropism. During growth, the stem of the planted crop becomes thicker, and the aperture slit 906 can be configured to be flexible, allowing the aperture to widen to accommodate the thickening of the stem. In a cruciform slit configuration, the leaflet of the aperture slit 906 is configured to compress outward along the direction of stem growth to widen the aperture 906.

[0110] After a period of growth, the stems of the planted crop can be easily harvested when they extend outward from the first surface 902A of the planting plug 900 through the hole 906.

[0111] In use, the second configuration is set to separate and / or break the roots of the planted crop. This facilitates easy removal of the planted crop roots from the planting plug 900 after harvesting. The reusable planting plug 900 can then be easily cleaned for reuse with another planted crop.

[0112] Figures 11A to 11D Another exemplary reusable implant plug 1100 is shown. The implant plug 1100 includes a first surface 902A and a second surface 902B opposite to the first surface 902A, the first surface 902A and the second surface 902B forming a flexible diaphragm 902.

[0113] The implant plug 1100 also includes a hole 906 centrally disposed in the diaphragm 902, the hole 906 extending through the first surface 902A and the second surface 902B. In the example shown, the hole 906 is circular. In other examples, other slit or hole shapes may be used.

[0114] Multiple pin portions 904 extend from the second surface 902B of the diaphragm 902. In the example shown, there are twenty-eight pin portions 904. In other examples, there may be more or fewer pin portions 904. In this example, the pin portions 904 are equally spaced along the second surface 902B of the diaphragm 902 in a circumferential manner surrounding the hole 906. In other examples, the pin portions 904 may have different arrangements.

[0115] Each pin portion 904 includes a proximal end 1102 and a distal end 1104, wherein the proximal end 1102 is coupled to the second surface 902B of the diaphragm 902, and the distal end 1104 extends away from the diaphragm 902. Each pin portion 904 may have a generally tapered shape, for example, wherein the cross-sectional area of ​​each pin portion 904 at the proximal end 1102 is greater than the cross-sectional area at the distal end 1104. In this example, the proximal end 1102 of each pin portion 904 spans the height of the second surface 902B of the diaphragm 902.

[0116] The diaphragm 902 optionally includes a flange 910. In this example, the flange 910 is disposed at the outer edge 1106 of the diaphragm 902, wherein the outer edge 1106 is defined as the edge of the diaphragm 902 furthest from the aperture 906. Optionally, the outer edge 1106 of the diaphragm 902 may have a larger perimeter than the inner edge 1108. In other examples, the flange 910 may be disposed at any other peripheral location of the diaphragm 902. In some examples, the resilient portion may have a flange 910 disposed at the outer edge 1106 of the diaphragm 902 and a second flange disposed at the inner edge 1108 of the diaphragm 902 or disposed at any other peripheral location along the diaphragm 902.

[0117] In some examples, the implant plug 1100 is made of rubber.

[0118] Figure 11A and Figure 11CAn exemplary implant plug 1100 arranged in a first configuration is shown, wherein a diaphragm 902 is biased to form a conical shape, in this example a truncated cone similar to a cone, wherein the outer edge 1106 of the diaphragm provides the base of the truncated cone. In contrast to the second configuration, in the first configuration, a plurality of prongs 904 are clustered together.

[0119] Figure 11B and Figure 11D An exemplary implant plug 1100 arranged in a second configuration is shown, wherein the diaphragm 902 is biased to form an inverted cone shape, opposite to the truncated cone shape of the first configuration. This can be achieved by changing the position of the outer edge 1106 of the diaphragm 902 relative to the inner edge 1108 of the diaphragm 902. For example, in the first configuration, the outer edge 1106 of the diaphragm 902 can be vertically displaced from the inner edge 1108 such that the first surface 902A faces outward, for example, where, as Figure 11A and Figure 11C As shown, the outer edge 1106 is positioned below the inner edge 1108. To convert the implant plug 1100 to a second configuration, the position of the outer edge 1106 of the diaphragm 902 relative to the inner edge 1108 can be reversed, such that the second surface 902B faces outwards in the second configuration, for example, as shown in the diagram. Figure 11B and Figure 11D As shown, the outer edge 1106 is arranged above the inner edge 1108.

[0120] In contrast to the first configuration, in the second configuration, a plurality of pin portions 904 are separated. In this example, the plurality of pin portions 904 are separated in a radial arrangement such that the pin portions 904 extend radially around the hole 906 in the second configuration. In the radial arrangement of the second configuration, the plurality of pin portions 904 are configured to lie in the same plane as the diaphragm 902 and / or the hole 906, for example, such that the implant plug 1100 is configured to lie flat in the second configuration.

[0121] At least a portion of the diaphragm 902 can be configured to be supplied by a hydroponic system (such as...) Figures 1 to 8CThe plant plug 1100 is received in a receiving hole in any of the hydroponic systems shown. In some examples, at least a portion of the diaphragm 902 may be configured to engage with the periphery of the receiving hole in the hydroponic system via a friction fit. In some examples, the flange 910 may be configured to secure and / or seal the plant plug 1100 within the receiving hole in the hydroponic system, for example, by engaging with the edge of the hole. For example, when the flange 910 is positioned at the upper edge of the resilient portion 908, the flange 910 may prevent the plant plug from passing through the receiving hole and falling into the conduit in the hydroponic system. When the flange 910 is positioned at the lower edge of the resilient portion 908, the flange 910 may prevent the plant plug from falling out of the receiving hole in the hydroponic system during rotation.

[0122] In use, the first configuration is set to grip the planted crop between the prongs 904. This secures the planted crop in place within the planting plug 1100.

[0123] As the planted crop grows, the root system extends along the cutting 904. When in situ in a hydroponic system, this allows the roots to extend into, for example, the nutrient and fluid supply sections located within the tubing.

[0124] Before the root system develops, the planted crop can receive fluid from the prongs 904, which retains some of the passing fluid through surface tension. During rotation, the retained fluid can travel along the prongs 904 to the planted crop.

[0125] The plant's stem grows in the opposite direction to the root system, and as the stem grows, it protrudes through hole 906. This is likely driven by the plant's phototropism. During growth, the plant's stem thickens, and hole 906 can be configured to be flexible, widening to accommodate the thickening of the stem.

[0126] After a period of growth, the stems of the planted crop can be easily harvested when they extend outward from the first surface 902A of the planting plug 1100 through the hole 906.

[0127] In use, the second configuration is set to separate and / or break the roots of the planted crop. This facilitates easy removal of the planted crop roots from the planting plug 1100 after harvesting. The reusable planting plug 1100 can then be easily cleaned for reuse with another planted crop.

[0128] Figure 10A method 1000 for using reusable planting plugs (e.g., reusable planting plugs of the second aspect of the invention, such as planting plugs 900 or 1100) within a hydroponic system (e.g., the hydroponic system of the first aspect of the invention). First, seeds / planted crops are placed between a plurality of prongs of a planting plug in a second configuration (1010). Then, the planting plug is biased to a first configuration such that the plurality of prongs come together, thereby gripping the seeds / planted crops between the prongs to secure them (1020). The planting plug can then be placed into holes in a hydroponic planting frame for receiving the planted crops (1030). These steps can be repeated for a plurality of planting plugs (1040), optionally until all holes in the hydroponic system for receiving the planted crops have received planting plugs.

[0129] The hydroponic system is then operated (1050) during a growth cycle. The operation involves rotating the rotating portion of the hydroponic planting frame. This supplies a nutrient-rich fluid via spiral conduits in the planting frame, allowing the fluid to flow through multiple planting plugs that hold the seeds / planted crops. As the seeds / planted crops grow, the plants will emerge through holes in the planting plugs.

[0130] After the growth cycle, the planted crop can be harvested (1060). Harvesting can be carried out while the crop is still within the planting inserts and hydroponic planting frame. Optionally, the rotating part of the hydroponic planting frame can be rotated to facilitate harvesting by bringing the planted crop to an easily accessible height.

[0131] The planting plug is then biased to the second configuration to break off the roots of the remaining plant tissue after harvesting (1070). This facilitates the cleaning and removal of the plant tissue.

[0132] The hydroponic system is then operated (1080) during a cleaning cycle. The operation includes rotating the rotating portion of the hydroponic planting frame. This supplies fluid via the spiral conduit of the planting system, allowing the fluid to flow through multiple planting plugs to wash away residual plant tissue and debris. Optionally, during the cleaning process, air can also be blown through the spiral conduit to remove residual dried roots and debris.

[0133] The planting plug can then be removed from the hydroponic planting frame (1090). In some examples, the planting plug may undergo further cleaning steps, including rinsing.

[0134] This method can then be repeated 1000 times for different crop cycles.

[0135] In other examples, multiple planting plugs are not removed from the hydroponic planting frame between crop cycles. In these examples, the planting plugs are biased to a first configuration within the hydroponic planting frame, and the seeds / planted crops can be squeezed through the holes in the planting plugs during planting to be secured between the multiple prongs of the planting plugs. As described above, steps 1050 to 1080 of the method can then be performed, wherein the hydroponic system is manually or using a motor to rotate during a growth cycle (1050) before harvesting the planted crops from the planting plugs within the hydroponic planting frame (1060). The multiple planting plugs are then biased to a second configuration to break off the roots of the harvested planted crops and facilitate cleaning (1070). The hydroponic system can then be rotated during a cleaning cycle (1080). After cleaning, the planting plugs are again biased to the first configuration within the hydroponic planting frame. The planting plugs can be switched between the first and second configurations while remaining within the hydroponic planting frame. The method can then be repeated for different crop cycles.

[0136] In the context of this disclosure, other examples and variations of the apparatus and methods described herein will be apparent to those skilled in the art.
