A hydroponic grow assembly including an assembly base and at least one plant structure removably connectable to the assembly base to form a plant wall for growing plants. The plant structure includes a plurality of plant wells opened to a root chamber and the base includes a bottom structure enclosed by a perimeter wall to form an inner cavity of a reservoir tank to supply water to the root chamber of the plant structure. The bottom structure includes a support feature within the inner cavity of the reservoir tank to support the at least one plant structure in an upright position to form the plant wall of the assembly.

A hydroponic cultivation apparatus, a system and a method for facilitating hydroponic cultivation is disclosed. The hydroponic cultivation apparatus includes a reservoir, a plinth, a grow tray with a grow tray lid, and a docking with coupler. The reservoir, placed upon the plinth, is located at a higher position adjacent to the grow tray for optimizing liquid circulation from the reservoir to the grow tray and vice-versa using one or more pipes, a solenoid valve and a pump. The base further includes a dock coupled to the grow tray for providing an electrical connectivity to the grow tray and simultaneously allowing the liquid to flow through the grow tray without being leaked. Further, the apparatus is having a roof which is provided with sources of illumination for providing light required for plant growth.

A nutrient dosing system including: a mixing tank for receiving a solvent and at least one nutrient medium; and at least one dosing device, each dosing device being fluidly connected to the mixing tank. Each dosing device includes a nutrient tank for storing a nutrient medium, a reciprocating pump having an inlet port fluidly connected to the corresponding nutrient tank, and an outlet port fluidly connected to the mixing tank, and an actuator configured to actuate the reciprocating pump. The nutrient dosing system also includes a controller configured to, for at least one dosing device, control the respective actuator to cause the corresponding reciprocating pump to: load the nutrient medium from the corresponding nutrient tank; and inject a target amount of nutrient medium into the mixing tank.

A gardening appliance includes a grow tower rotatably mounted within a liner and defining a root chamber. A mixing tank defines a water inlet, a nutrient inlet, and a mixture outlet. An overflow protection system is operably coupled to the mixing tank and includes a wastewater reservoir, an overflow port fluidly coupled to the mixing tank, an overflow conduit providing fluid communication between the overflow port and the wastewater reservoir, and a one-way overflow valve fluidly coupled to the overflow conduit to prevent liquid flow back into the mixing tank.

An object of the present invention is to propose cultivation equipment that can curb complication and upsizing of the equipment even when the number of cultivation stages is increased. Cultivation equipment includes a storage shelf (1) and a plurality of cultivation tanks (3) that are stored in the storage shelf (1) and hold plants (P1) and a cultivation liquid (L1). The cultivation equipment further includes a discharge device (50) and a supply device (51). The discharge device (50) is movable among a plurality of cultivation tanks (3), and discharges the cultivation liquid (L1) from each of the plurality of cultivation tanks (3). The supply device (51) is movable among the plurality of cultivation tanks (3), and supplies the cultivation liquid (L1) to each of the plurality of cultivation tanks (3).

A system and method for growing plants by reducing the need for additional water. The hydroponic plant growth system utilizes a reservoir to collect excess water from the support tubes or feeder tubes and refeed the water to the plants through the pump. The water fed to the plants is mixed with nutrient enriched air which is sent directly to the plant roots through the inlets along with the water. This helps the plant absorb the required nutrients and the availability of nutrients is maintained as the water is pumped by the reservoir continuously in this closed loop system.

A gardening appliance includes a liner positioned within a cabinet and defining a grow chamber, a grow tower rotatably mounted within the liner and defining a root chamber, a sealed system including an evaporator, and a hydration system. The hydration system includes a supply conduit for providing a flow of liquid into the root chamber, a condensate collection tray positioned below the evaporator and defining a condensate collection reservoir for collecting condensate formed by the evaporator while the sealed system is operating, and a condensate return conduit fluidly coupling the condensate collection reservoir and the supply conduit for supplying the condensate into the supply conduit.

The apparatus for providing nutrients to plants in a hydroponic plant growing system contains a nutrient release capsule and a capsule holder. The nutrient release capsule is a sustained release nutrient product comprising a hydroponic plant fertilizer center with a biopolymer outer coating to slow the release of the nutrients into the liquid (e.g., water). The capsule holder consists of a modifiable structure that can exist in multiple configurations to deliver different release dosage behaviors into and in response to the liquid for the hydroponic plant fertilizer.

Disclosed are high-density soil-less hydroponic cultivation systems, apparatus used therein, and methods of operation thereof. A high-density soil-less cultivation system can comprise one or more grow columns, each comprising a column lumen, and one or more angled housings coupled to the grow columns. The system can further comprise a nutrient reservoir configured to contain a nutrient solution to be delivered to the grow columns, a capture conduit coupled to the grow columns configured to capture or recapture nutrient solution flowing through the grow columns, and a capture reservoir configured to collect the captured or recaptured nutrient solution from the capture conduit for delivery to the nutrient reservoir to be reused. The system can also comprise an omnidirectional light tower configured to shine light on the one or more angled housings to induce growth of any plant matter within the angled housings.

The present invention is a system and method comprising a vertical farm where the plants are nourished by an aqueous nutrient solution and where all operations of the farm: the circulation of aqueous nutrient solution, replenishment of nutrients and supplements to the solution, as well as the seeding, growing, harvesting and packaging of plants are able to be effected in an automated manner and controlled by the farm controller system. It is possible for the operations of the present invention to be non-automated, semi-automated, or fully-automated, or any combination of non-automated, semi-automated and fully-automated operations, and to be controlled either centrally or locally.
