Present invention relates to a hydroponic plant grow cabinet, comprising a housing, said housing comprising main plant growing chamber and a pre-growing chamber for seeds/seedlings, main tank and auxiliary tanks for a nutrient solution and pH level regulating solutions, pumps and tubing, lighting means, ventilating means, control means, sensors, display means, loudspeaker and user input means, network communication means, connection to electric main, connections to water mains and sewage.

A green red blue (GRB) LED is used to emit electromagnetic radiation to treat water or a nutrient for plant growth enrichment. In addition to the LED, a cavity resonator is used to resonate with background electromagnetic radiation and direct the electromagnetic radiation to treat water or a nutrient for plant growth enrichment.

A hydroponic growing system is disclosed herein. The hydroponic growing system includes a plurality of plant containers, a nutrient reservoir, a nutrient control tower, a plumbing means, a pump, and an overflow tube. The hydroponic growing system is useful for pumping a nutrient solution to the plurality of plant containers from the nutrient reservoir. A method is also disclosed herein.

A vertical growing system includes a nutrient cap and a base that removably support a grow tower formed from a pipe with a number of grow pockets adhered to the pipe. The roots of plants in the grow pockets extend inside the pipe, where they are hydrated by irrigation fluid flowing from the cap, through the pipe, through the base, and into a reservoir or collection system. A user can easily install and remove the pipe without having to remove the cap or base. The cap contains nutrient media, such as charged biochar and coarse sand, that supplies nutrients to the irrigation fluid as it percolates through the cap. A 4-tower embodiment included four grow towers above a reservoir. A submersible pump supplies irritation fluid from the reservoir to the nutrient caps. A central light rotates to illuminate the plants in light-dark cycles.

The invention relates to an irrigation system for hydroponic crops, of the type used in growing tanks (1) containing a nutrient solution, and which is formed by a grid (2) partially submerged in the nutrient solution of the growing tank (1), the grid (2) being formed by straight channels (3) separated from each other by adjacent cells (4) in which the plants to be grown are arranged, said cells being connected to the channels (3) and/or to each other, the channels (3) having a cross section in the shape of an inverted U. The system comprises at least one irrigation emitter (5) disposed in a channel (3) of the grid, the emitter (5) being configured to emit a volume of nutrient solution into the nutrient solution contained in the tank (1) or onto the surface (10) of same. The invention also relates to an irrigation method.

An indoor soilless plant cultivating system. The system has a plurality of (a) stationary light posts, (b) plant growth towers, and (c) irrigation means. Each post is adapted to illuminate a predetermined sector of an indoor facility in accordance with a predetermined illumination signature. Each tower is rotatable about a substantially vertical axis in accordance with a predetermined timing sequence so as to be exposable to the light generated at any given time by one or more of the light posts and that are arranged by at least one module defining a module darkened interior region within which plants being instantaneously positioned receive a sensation of nighttime. The irrigation means supplies the plants being cultivated in each of said towers with a nutrient-rich solution.

The specification discloses a hydroponic nutrient aeration and flow control (NAFC) device and system, which both aerates and controls the flow of the hydroponic nutrient solution. The NAFC device has no moving parts. Each NAFC device mixes and aerates the nutrient from the nutrient reservoir with air and/or nutrient from one of the grow tanks. Each NAFC device additionally controls the flow of the aerated nutrient solution to the grow tank and the nutrient reservoir. The vertical position of the end of the nutrient return line in each grow tank may be adjusted to adjust the level of the nutrient solution within the grow tank.

A system for vertical hydroponic plant growing. The system, and associated apparatuses and methods, may include or use sprockets, a sprocket drive device that is connected to at least one sprocket among the sprockets, a first continuous loop chain that is mounted on the sprockets, a second continuous loop chain that is mounted on the sprockets, and trays. Each tray includes a first end and a second end that includes a drain hole. The trays are attached to the first continuous loop chain and to the second continuous loop chain. The system also includes a fluid-dispensing device that is configured to dispense a fluid into a tray that is moved by the chains to a position adjacent to the fluid-dispensing device. The chains are configured to longitudinally tilt a tray downward towards the drain hole while the tray is near the position adjacent to the fluid-dispensing device.

An indoor system and process for cultivating, harvesting, and outputting a culture of aquatic plants, namely duckweed, are provided. The system includes a water treatment system and cultivation and harvesting system. The water treatment system provides for mixing of nutrients and treated water to form a treatment mixture which is supplied to the cultivation and harvesting system for facilitating growth of the duckweed.

The present disclosure relates, according to some embodiments, to methods and systems for purifying proteins and carbohydrate rich products from photosynthetic aquatic species and compositions thereof. For example, one embodiment of the present disclosure relates to methods and systems for purifying proteins the present disclosure relates, in some embodiments to methods and systems for extracting proteins, dry biocrude, and carbohydrate-rich meal from Lemna. In some embodiments, a method of treating a biomass comprising a microcrop (e.g., Lemna) to produce a product comprising soluble microcrop protein may comprise: (a) lysing a first portion of the biomass to form a first portion of lysed biomass; (b) separating the first portion of lysed biomass to generate a first portion of a juice fraction and a first portion of a solid fraction; (c) separating the first portion of the juice fraction to generate a first portion of a first juice and a first portion of a first cake, wherein the first juice comprises a soluble microcrop protein; and/or (d) filtering the first portion of the first juice to generate a first portion of the product comprising soluble microcrop protein and a reject stream.
