Systems and methods for hydroponic plant cultivation are disclosed herein. The systems can include a water management unit, a bioreactor, and one or more plant growth regions. Plants may be cultivated on floats disposed in the one or more plant growth regions. The bioreactor can include a substrate upon which one or more of bacteria, fungi, and/or other microorganisms can reside. A nitrogen feed source can be delivered to the bioreactor where it is converted into nitrates via a nitrification process. Plasma activated water can also be added to the system.

Growing systems may include a number of modular growing chambers adapted to be configured in a stacked arrangement with each growing chamber surrounding a corresponding portion of the plant. The grow chambers may be selectively added or removed during plant growth, such that different sections of the growing plant may be influenced differently using aeroponic, hydroponic or other growing techniques. The grow chamber stack may be portable and provided with integrated or independent lifting devices to assist an operator in adding or removing chambers from the stack. Three growing processes may be facilitated using such systems. These include a process for producing assorted product from a single plant for simultaneous harvest, a process for producing an extended harvest of a desired size product from a single plant, and a process for extending the productive life of a plant and provide for multiple, continued, and perpetual harvest.

A hydroponic growing system is presented. The system can include multiple growing trays in a vertical arrangement, where a pump supplies the top-most tray and each lower tray is supplied by the overlying tray, and where the plumbing elements for supply and drainage are arranged to one side of the system. The system includes variations to support different crop types within the same system, including removable growing structures for root vegetable, microgreens and supports for vining crops. The system can monitor and adjust the nutrients and other features of the systems water profile to concurrently group multiple crops in differing developing stages.

The present invention provides various modular hydroponic growing apparatuses, each having oppositely positioned slats or other compatible surfaces between which is defined an expandable growth channel, wherein at least one of the slats or other compatible surfaces are biased inwardly towards the opposing slat or other compatible surface via a biasing element.

A growing system is described. The growing system includes a conveyor system, at least one floating tray, a plurality of multifunction beams arranged to contain at least one row, a microclimate exchange system, and a nutriment supply system.

Growing systems may include a number of modular growing chambers adapted to be configured in a stacked arrangement with each growing chamber surrounding a corresponding portion of the plant. The grow chambers may be selectively added or removed during plant growth, such that different sections of the growing plant may be influenced differently using aeroponic, hydroponic or other growing techniques. The grow chamber stack may be portable and provided with integrated or independent lifting devices to assist an operator in adding or removing chambers from the stack. Three growing processes may be facilitated using such systems. These include a process for producing assorted product from a single plant for simultaneous harvest, a process for producing an extended harvest of a desired size product from a single plant, and a process for extending the productive life of a plant and provide for multiple, continued, and perpetual harvest.

A cultivation enclosure for growing crops includes a chamber. The chamber includes a base and a lid configured to cover the base. The chamber is connected to a rack. The rack includes one or more inlets and one or more outlets. The rack is configured to dispense water and minerals into the chamber through the one or more inlets or discharge water from the chamber through the one or more outlets.

A plant cultivation apparatus and system including a reservoir and central shaft containing a first and second end, wherein the first end of the central shaft terminates in the central chamber of the reservoir. One or more trays are positioned along the central shaft with variable distances between each tray. The plant cultivation apparatus and system also includes an outer housing member having a plurality of plant-receiving apertures. The outer housing member defines a chamber and has a bottom edge. The bottom edge defines a respective opening, which is configured to contact a reservoir opening. The hydroponic apparatus and system may further include a lighting system mounted above the outer housing member, the lighting system illuminating plants inserted into the plant-receiving apertures to enable the associated plants to photosynthesize in environments exposed to low levels of sunlight.

Modular systems for propagating plants in at least one of a hydroponic environment and an aquaponics environment may include at least one tank configured to hold liquid. A modular drive assembly may be carried by the at least one tank. At least one propagation module may be drivingly engaged for rotation by the modular drive assembly. The at least one propagation module may be configured to support and propagate at least one plant. At least one pump may be disposed in fluid communication with the at least one tank. The at least one pump configured to pump the liquid from the at least one tank through the at least one propagation module. Modular methods for propagating plants in at least one of a hydroponic environment and an aquaponics environment are also disclosed.

A system for growing plants includes a water circulation system connecting a plurality of deep water culture tanks in series and/or in parallel through which water is provided to plants housed in the tanks; a nanobubble generator for oxygenating the water; and a water cooling and disinfecting apparatus.
