The specification discloses a DWC hydroponic system that includes a plurality of grow tanks, a circulation pump, a nutrient supply line fluidly connecting the outlet of the circulation pump to the grow tanks, and a tank drain line fluidly connected to the grow tanks. Each of the grow tanks is fluidly connected in parallel between the nutrient supply line and the tank drain line. The system further includes a pump suction line fluidly connected to the inlet of the circulation pump, and a plurality of bridge connectors each fluidly connecting the tank drain line to the pump suction line in accordance with a defined pattern. The DWC system may further include a nutrient supply fluidly connected to the circulation pump intake through a valve arrangement.

An aquaculture system including a fish tank, a floating media bioclarifier, and a mineralization tank. The mineralization tank includes a first influent inlet for receiving sludge having a first solids concentration from the bioclarifier, an effluent outlet for returning to the bioclarifier a fluid having a second solids concentration less than the first solids concentration, and a second influent inlet configured to receive influent from the fish tank which has bypassed the bioclarifier. A hydroponic system is configured to receive effluent from the bioclarifier.

A container unit for hydroponics includes a container having an overflow unit and an outflow unit located therein. The overflow unit includes an overflow tube, and the outflow unit includes a siphon pipe which is height adjustable. A cover is mounted to the container and includes an opening, a first hole and a second hole. A pot is engaged with the opening of the cover. Two hooks are connected to the back of the container so as to be hooked to a shelve to form multiple rows of the containers between which the overflow tubes and the outflow tubes are connected via the first and second holes of the containers. The overflow tube and siphon pipe control the water level in the container to prevent plant root from being rotted.

The present disclosure relates, according to some embodiments, to systems for purifying proteins and carbohydrate rich products from photosynthetic aquatic species and compositions thereof. In some embodiments, a system for recovering a highly soluble protein product from a biomass comprising a microcrop (e.g., Lemna) may comprise (a) a lysing unit to lyse a first portion of the biomass to form a first portion of lysed biomass, (b) a first separating unit to separate the first portion of lysed biomass to generate a first portion of a juice fraction and a first portion of a solid fraction, (c) a second separating unit to separate the first portion of the juice fraction to generate a first portion of a first juice and a first portion of a first cake, (d) a first filtration unit to filter the first portion of the first juice to generate a first portion of a soluble protein and a first reject stream, (e) a second filtration unit to filter the first portion of the soluble protein to generate a first portion of a second soluble protein and a second reject stream, (f) a dewatering unit to concentrate the first portion of the second soluble protein to generate a first portion of a concentrated soluble protein, and (g) a drying unit to dry the first portion of the concentrated soluble protein to generate a first portion of a dry protein concentrate.

A cultivation method for cultivating leaf vegetables includes preparing correspondence information associating light characteristic information indicative of a characteristic of light with which leaf vegetables are irradiated, with quantified quality information having a quantified quality of leaf vegetables; setting the light characteristic information; and irradiating the leaf vegetables with light.

A hydroponic growth system comprises a reservoir including a lower chamber, an upper chamber, and a divider therebetween. The divider has a first aperture and a second aperture. The system includes an air blower in fluid communication with the lower chamber. Actuation of the air blower causes fluid from the lower chamber to pass through the first aperture and selectively flood the upper chamber. The valve inhibits communication between the lower chamber and the upper chamber via the second aperture in a resting state. Upon actuation of the air blower, the valve moves to a flooding state in which communication between the lower chamber and the upper chamber via the second aperture is promoted.

A hydroponic growth system comprises grow tubes and a misting assembly. Each of the grow tubes, of a generally hollow cylindrical configuration, are mounted vertically on a support assembly and comprise openings configured on an outer surface of the grow tube for receiving receptacles containing plants. Each of the grow tubes comprise a top vent and a bottom vent. The misting assembly comprises spray tubes inserted into a middle section of the grow tubes to distribute and spray a nutrient solution into an inner surface of each of the grow tubes. The nutrient solution is absorbed by roots of the one or more plants extending into the inner surface of the grow tubes. Unused nutrient solution is drained into a sump positioned beneath the grow tubes via the bottom vents and recirculated within the misting assembly for spraying the nutrient solution to grow the plants.

A block storage element which is used for the propagation of vegetable or fungal biomass and is stackable. To enhance functionality of the block storage element, the block storage element includes a fluid reservoir with an overflow mechanism.

A farming method includes: loading a broad spectrum of plant nutrients into a zeolite substrate; using the loaded zeolite substrate to grow crops for a plurality of cycles; and recycling the used zeolite substrate.

Systems and methods of generating water for growing or vitally supporting plants, fungi, and/or aquatic animals are provided herein. The systems include a water generating unit that utilizes process fluid produced by plant transpiration or fungus respiration to generate water. Nutrients may be added to the water through hydroponic and aquaponic systems, then provided back to the plants in a closed loop. The systems may be monitored, optimized, and controlled remotely.
