Methods and systems for cooling plant roots in an aeroponics unit are disclosed. One such system includes a growing unit coupleable to a mist generator for delivering a mist within the growing unit. The growing unit includes two opposing side walls connected by a top wall, a base, a front wall and a back wall with plant receptacles on the front wall. A lower opening in one of the opposing side walls, the back wall, the front wall, or the base and an upper opening in one of the opposing side walls, the back wall, the front wall, or the top wall are shaped and positioned to allow a root cooling convection air current to form between the lower opening and the upper opening to cool plant roots by allowing ambient air to enter the enclosure through the lower opening and warmer air to exit through the upper opening.

A plant growing apparatus that has at least one panel separating an interior from a surrounding environment and a plant housing assembly positioned at least partially in the interior, the plant housing assembly comprising at least one growth ring that defines at least one plant opening through a radial bend in a growth ring wall.

The specification discloses a hydroponic nutrient solution aeration device that has no moving parts. The aeration device includes an aerator and a converging nozzle. The aerator includes a nutrient inlet, an air inlet port, and a diverging nozzle. The converging nozzle is adjacent the diverging nozzle. The largest portion of the converging nozzle is connected to the largest portion of the diverging nozzle. The aeration device uses a relatively small volume flow rate to entrain a significant amount of air.

There is provided an off-ground plant growing system providing an electronic monitoring system and also providing a thin layer of high porosity organic compost and providing the steps of adding a precise amount of vermicompost to the soil phase, immediately followed by addition of arbuscular mycorhizae, and followed by regular weekly addition of beneficial micro-organisms for plant development, including mycorhizae associated bacteria, plant growth promoting fungi, soil conditioning bacteria, purple non-sulphur bacteria and probiotic disease-preventing bacteria, in order to promote the creation of a well differentiated, dense and ramified root system and complete microrhizobiome in the compost phase, that can effectively assist the functions of plant roots for optimal precision greenhouse, green walling or homegrown crop production of all kinds, without the use of chemical pesticides or fungicides.

This disclosure pertains to modular, moveable light weight structures, i.e., grow towers, including supporting tubing and pumps, used for a hybrid aeroponic and aquaponic growth method of plants and aquaponic growth of animals such as fish wherein the each of the plants and animals are balanced in quantity and produce nutrients that support the growth of the other, i.e., plants and animals. The disclosure also includes an array of sensors, software utilizing artificial intelligence and a CPU for monitoring, controlling and facilitating the growth. The structure and methods utilize and maintain a substantially equilibrium growing conditions requiring minimum intervention. The structure and method also utilizes monitoring of multiple growth variables with systems and CPU programing to adjust and maintain equilibrium conditions.

A modular commercial plant cloning system and method for stimulating root growth from a plant stem. The system includes a supporting frame, a light source, a fluid reservoir, and a cooling element. The supporting frame further includes a plurality of mounting points for securing a plant holding device tray at a desired height and spacing within the supporting frame below the light source. The plant holding device tray houses a plurality of plant holding devices that the plant stems are placed in during the cloning process. The lower end of the supporting frame includes the fluid reservoir, wherein the fluid reservoir further includes a cooling element therein. Additionally, the fluid delivery system helps transport fluid from the fluid reservoir to the sprayer nozzles which are configured to distribute fluid across the plant stems disposed within the plant holding device tray.

The present application is directed to a hybrid hydroponic and aeroponic plant cultivation system comprising a main reservoir supplying a nutrient solution to a root mass contained within an interior cavity of a cultivation chamber having a lateral sidewall and a chamber outlet, the lateral sidewall having a top edge and a bottom edge, wherein the chamber outlet is configured to allow drainage of the nutrient solution from the interior cavity of the cultivation chamber. Attached to the chamber outlet is a nutrient solution retention system comprising a drainage conduit, a bypass conduit, and a liquid level switch operatively coupled to the drainage conduit, wherein the liquid level switch is configured to restrict the flow of nutrient solution through the drainage conduit causing the root mass to be submerged in a volume of nutrient solution retained in the cultivation chamber.

The present invention is a plant cultivation device. The water tank supplies cultivation water to the cultivation tank via an irrigation conduit. The water tank also suctions cultivation water from the cultivation tank via a water-sucking pipe. The heat-collecting part receives sunlight, and the pressure of air that is heated inside the air-storage part presses the surface of the water inside the water tank. The water tank supplies cultivation water that has been pressed by the air to a culture medium material. The heat-collecting part raises the surface of the water inside the water tank as a result of the heated air being cooled by a decrease in the sunlight. The water tank suctions cultivation water from a bottom section of the cultivation tank.

A device for growing plants is provided. The device has a panel assembly on which a one or a plurality of nutrient flow channels is supported to provide nutrient flow passages from an inlet at an upper region to an outlet at a lower region of the support panel. A plurality of grow pockets is supported on an opposite side face of the support panel, the grow pockets in alignment with the nutrient flow channels. Each grow pocket has a plant access opening. A fluid aperture in the support panel is disposed at a lower region of each grow pocket for fluid communication between an interior of the grow pocket and the aligned nutrient flow passage.

A water-circulation irrigation system includes a water supply device and a planting device. The planting device includes a water storage container, an irrigation pipeline, a nozzle and a recycling pipeline. One end of the irrigation pipeline is in communication with the water storage container and has a water supply end. The planting device includes a water collection container, a planting tray and a shunting element. The water collection container has a water dispensing post. The planting tray is disposed at an opening of the water collection container. The planting tray has a fitting portion and a through hole and corresponds in position to a water collection space of the water collection container. The shunting element includes a fertilizer chamber and is disposed at the rim of the through hole of the fitting portion. Therefore, a fertilizer solution is produced in a manpower-efficient manner and thus conveniently.
