An indoor farming system includes a water-based nutrient bath resident in a tank and a pump for pumping the bath from the tank upwardly through a plurality of pipes to at least one divided high-density table comprising growing crops resting in at least one float. The plurality pipes includes at least one valve suitable to shut off the bath per each of the high density tables. At least one non-block drain is coupled to the at least one divided high-density table. The bath turbulently flows respectively across the at least one divided high-density table, down the at least one non-block drain, and back into the tank that includes the nutrient bath. A lighting system provides moving light from points above the growing crops.

A grow tray including a perimeter wall and a base. The base includes an irrigation opening extending through the base for allowing fluid to enter and leave the grow tray. The base is couplable to a conduit to allow fluid communication between the conduit and the base via the irrigation opening.

An indoor gardening appliance includes a grow module that is seated on a turntable that is rotatably mounted within a grow chamber and is rotated by a drive assembly. A position sensing assembly monitors an angular position using two proximity sensors, such as Hall-effect sensors, mounted below the sump, and the turntable includes a plurality of proximity indicators, such as magnets, positioned at various circumferential positions on the turntable. A controller is configured to initiate rotation of the turntable from a first angular position, determine that the turntable should have reached a second angular position, e.g., based on the operating duration or drive signal of the drive motor, and identify a drive assembly fault upon determining that the turntable has not reached the second angular position.

The present invention relates to a medium cultivation system including: a cultivation bed in which plants are placed and which allows the plants to be cultivated by means of a nutrient solution; a nutrient solution tank in which the nutrient solution to be supplied to the cultivation bed is stored; and an apparatus for sterilizing a nutrient solution which sterilizes waste nutrient solution, discharged from the cultivation bed, for reuse or disposal or sterilizes the nutrient solution stored in the nutrient solution tank for supply to the cultivation bed, wherein the apparatus for sterilizing the nutrient solution is provided with a sterilizing unit, which sterilizes the nutrient solution to be sterilized, by supplying a sterilizing gas in the form of bubbles to the nutrient solution to be dissolved therein, and a sterilizing gas generator, which generates the sterilizing gas.

This invention is a hydroponic appliance that allows users to grow sufficient yields of fresh produce with relatively little maintenance. The appliance incorporates multiple features required for hydroponic plant cultivation into a plug-and-play system with a feedback loop to manage optimal growing conditions, comprising a growing area, a processor, a mixing chamber, and, in embodiments, more than one reservoir. In aspects, the grow area is divided between two or more reservoirs allowing users to stratify their crops or plant different crop types simultaneously. The apparatus and associated method provide the overall system with increased versatility, including removing aspects of day-to-day maintenance. The system automatically regulates the environment in response to various sensor readings. This includes automatically regulating the temperature, humidity, carbon dioxide level, pH level, and/or nutrient concentration. Accordingly, the plants have more optimum conditions for growth. The system utilizes, for example, pre-seeded trays, a single mixing chamber, a processor, and a plurality of reservoirs.

In various example embodiments, a bio cell system is described comprising one or more bio cell units, each comprising a primary tank and one or more secondary tanks, which tanks each comprise side walls, a floor connected to the side walls, and a removable cover. The cover of the tank comprises a lighting system comprising variable output lights and a controller connected to the lighting system comprising code for varying a time period of light output of the lights of the secondary tanks to be out of phase with a time period of light output of the lights of the primary tank.

Disclosed herein is a high growth, high density, closed environment growing system and methods thereof. A method of accelerating plant cell growth in a growing system may include adjusting the lighting in accordance with an identified plant growth stage.

An indoor farming system includes a water-based nutrient bath resident in a tank and a pump for pumping the bath from the tank upwardly through a plurality of pipes to at least one divided high-density table comprising growing crops resting in at least one float. The plurality pipes includes at least one valve suitable to shut off the bath per each of the high density tables. At least one non-block drain is coupled to the at least one divided high-density table. The bath turbulently flows respectively across the at least one divided high-density table, down the at least one non-block drain, and back into the tank that includes the nutrient bath. A lighting system provides moving light from points above the growing crops.

Tray assemblies organized in a vertical stack with a grow light positioned above each. Plant nutrient solution flows into a feed reservoir positioned in a first end of the top assembly. When plant nutrient solution reaches the level of outlets positioned in a sidewall of the feed reservoir, it flows into longitudinal channels positioned on the tray assembly. A collection reservoir at a second end of the tray assembly collects excess solution from the channels. A lip positioned between the channels and the collection reservoir retains some of the solution in the channels so it is available to plants held by the tray assembly. Excess solution flows from the collection reservoir of the top tray assembly to a feed reservoir serving the next tray assembly in the stack. The pattern is repeated while alternating the orientation of each tray assembly such that solution is provided to each tray assembly.

An aquaponic grow system includes a plurality of sensors for sensing nutrient levels in liquid provided to a grow chamber, and to adjust nutrient levels based on the sensed levels. In some embodiments the system includes a plurality of sensors configured to sense nutrient levels in a common chamber, with the system configured to calibrate the sensors.
