A sub-irrigation bed includes a bottom, a side wall surrounding the bottom, a water inlet, and a water outlet. A plurality of support structures is arranged on an upper surface of the bottom, and tops of at least a part of the plurality of support structures lie in the same horizontal plane. By reducing the contact area between the cultivation container and the surface of the sub-irrigation bed to reduce local water accumulation caused by surface tension, the sub-irrigation bed and the cultivation apparatus using the sub-irrigation bed provided by the present invention solve the problem of water accumulation caused by incomplete drainage and the resulting problems that roots grow out of the cultivation container and seedlings grow irregularly, thereby achieving a good root control effect.

A frame structure of aquaponic system assembled by module elements, comprising a base, at least a cultivating tank, a fix cover and a plurality of connecting members. Said elements of a frame structure are connected by the friction of elements through mortise-tenon joint and are easy for assembly and maintenance.

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.

An aeroponic growing system includes a plurality of parallel vertical aeroponic growing apparatuses each having a closable loop articulated wall made up of vertical strips or panels that are pivotally attached side-by-side together with flexible joints. The motor-driven articulated wall moves on rails as an oblong-shaped carousel. The panels are provided with numerous plant-growing cups such that the growing plant extends outwardly out of the cup while the roots thereof are located inwardly of the wall. A spraying system delivers nutrients to the roots in darkness. On the external side, plants are exposed to controlled lighting provided by a programmable vertical LED system. Every growing step of the plants is optimized and supported by sensors and interactive software. The articulated wall is disengageable from its aeroponic growing apparatus to be displaced along a railing system between a grow room and other areas, and/or inverted for the roots to face outward.

An irrigation system for a vertical farming structure having vertical grow towers and associated conveyance mechanisms for moving the vertical grow towers through a controlled environment, while being exposed to controlled conditions, such as lighting, airflow, humidity and nutritional support. The present disclosure describes a grow tower conveyance system that moves vertically-oriented grow towers to select positions along a grow line. An irrigation line having apertures at the select positions provides aqueous nutrient solution to the grow towers, while a gutter structure captures excess solution. In a closed loop system, the excess solution returns to a recirculation tank. The present disclosure provides a dual pump system for effectively and efficiently removing excess nutrient solution from the gutter structure.

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.

A method for priming a hydration system of a gardening appliance includes: activating a misting pump in order to urge a nutrient liquid from a mixing tank towards a misting nozzle oriented towards a plurality of plant pods on a grow tower rotatably mounted within a cabinet; receiving data from a pressure sensor corresponding to a pressure of the nutrient liquid between the misting pump and the misting nozzle; and switching a bypass valve open and closed in response to the pressure of the nutrient liquid being less than a threshold pressure for a predetermined period of time. The switching of the bypass valve open and closed purges air from a flow path for the nutrient liquid from the mixing tank to the misting nozzle.

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.

In various embodiments, an apparatus for growing plants is provided. The apparatus may include an irrigation apparatus, an accommodating space for accommodating one or more seed mats, and a controller which is configured to control the irrigation apparatus by a program controller. The irrigation apparatus includes a water circuit system for feeding water to the seed mats. The water circuit system includes at least one inlet, a water tank, at least one water circuit pump and at least one outlet. The irrigation apparatus includes a sensor which is configured to determine a conductance of the fed water.
