A gravity-driven plant cultivation system includes: (a) a frame; (b) a plurality of vertically stacked conveyor assemblies mounted to the frame. Each conveyor assembly includes at least one gravity conveyor extending along a conveyor axis. The conveyor axis slopes downwards relative to a horizontal plane from a frame upstream end to a frame downstream end of the frame. The system further includes (c) a plurality of plant cultivation trays rollingly supported on each gravity conveyor and urged to translate along a respective conveyor axis toward the frame downstream end via gravitational force.

Automatic watering systems for hydrating a cut tree or the like from a reservoir of standing water are described herein. Automatic watering systems may include a water source comprising a tank and a supply-water reservoir within the tank. Water may be automatically delivered from the supply-water reservoir to a tree-receiving reservoir which may be associated with a tree stand. Water in the tree-receiving reservoir may be taken up by the tree to keep the tree branches green and supple. A controller detects water levels in the supply-water reservoir and tree-receiving reservoir to control operation of a pump which pumps water to the tree-receiving reservoir for continuous tree hydration. The tank and other components of the system can be made to have the decorative appearance of a gift package to enhance the appearance of the tree and surrounding decor.

An assembly line grow pod includes a plurality of fluid lines fluidly coupled between a fluid source and a fluid destination within the assembly line grow pod, a plurality of valves, each coupled to a fluid line such that fluid movement through the fluid lines is selectively controlled by the valves, and a master controller communicatively coupled to the valves. The master controller is programmed to receive information relating to fluid delivery within the assembly line grow pod, determine one or more valves to direct the fluid, determine valve parameters for each of the valves that achieve the fluid direction, and transmit one or more control signals to the valves for directing the fluid within the assembly line grow pod.

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.

A flexible greening system integrated with water into fertilizer includes a vegetation fixing assembly, a vegetation growth layer and a water supply assembly. The vegetation fixing assembly is configured to connect to a building. The vegetation growth layer is provided on the vegetation fixing assembly and is configured for planting of green vegetation. The vegetation growth layer includes a substrate layer for vegetation growth and a drainage layer provided below the substrate layer. The water supply assembly is configured to supply the water to the green vegetation, and is provided with a drainage pipe communicated with the drainage layer.

An open-top gutter for cultivation of plants. In an example, the open-top gutter comprises at least one water space formed by a double edge and being closed at the top, or almost closed. The water space is open at the bottom of the gutter. In an example, the open-top gutter includes at least one separate water space formed by a partially double bottom and connected to the bottom of the gutter via a bottom gap. In an example, the open-top gutter includes a space limited by two side walls and a bottom wall and divided into trough-like compartments by at least one dividing wall. The dividing wall includes at least one water space formed by a double wall, open at the bottom of the gutter.

A system (100) for producing a plant (35), the system having an indoor environment, a plurality of plant holders (1) for growing and transporting a plant therein, a controller (105) for at least controlling temperature and humidity in the indoor environment. The plant holder has a semi-permeable foil (20) defining a non-planar boundary of an interior space and an exterior space, a reservoir (2), having an amount of liquid for feeding the plant. The reservoir (2) and the semi-permeable foil (20) are arranged to allow the plant to grow in the interior space. The semi-permeable foil (20) has permeation of water vapor.

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.

An irrigation apparatus for dispersing liquid through a plant growing medium is disclosed. The apparatus includes a geometrically shaped container of variable size. The container has an outer wall with an inner surface, an open top, and a base portion configured to cover the plant growing medium. The base portion is configured with multiple holes for receiving liquid therethrough, The holes are configured as raised half-circles to block light and receive air, water, and nutrients. The container is configured with at least one center opening therethrough having an inner wall for receiving a plant. The center opening has at least one longitudinal opening extending therefrom to outer wall to allow placement of container on plant or to allow removal of container from plant. The container is configured with multiple stakes of variable size extending therefrom the base portion for providing stability for apparatus to be secured in plant growing medium.
