An ebb and flow hydroponics system employs one or more containers for growing plants. Each container has a top and bottom, with a drain in the bottom and an overflow near the top. A return system connects the drains and overflow lines to a reservoir. The nutrient solution is delivered through gravity assist from the containers to the reservoir. A pump is connected to the reservoir and delivers nutrient solution under pressure to the containers. The solution is delivered at or near the top of each container to provide a top-feed ebb and flow system. Each container contains pea gravel, or other similar, nonporous material capable of supporting heavy plants, while providing optimal growing conditions. Fill and drain cycle time is also controlled for optimal growing conditions. Temperature and evaporation is controlled in part by placing the reservoir and a portion of the return system underground.

The instant invention describes a grow bag with a dosing irrigation tube inserted within the inner cavity of the grow bag for controllable dispersant of plant nutrients therein. The system comprises a top panel and a bottom panel secured to a plurality of side walls to form an inner cavity. Attached to the top panel is a dosing irrigation tube or pipe constructed and arranged to traverse the length of the bag and have a first and second end that is external to the inner cavity. Housed within the inner cavity of the bag is plant growth material for providing support and nutrients for the growth of one or more plant species. The invention also describes a system of two or more grow bags with a dosing irrigation tube coupled together and arranged in a variety of conjurations, including horizontally or vertically in a linear fashion or non-linear fashion.

An assembly well irrigation system for environmentally friendly water conservation includes: at least one well, having a ventilation tube inserted into the top of the well, an absorbent element covered onto the bottom and outer wall of the ventilation tube and filled up in an opening between the top of the well and the ventilation tube, and a float contained in the ventilation tube; and at least one water supply bottle, having a cover installed to the opening of the water supply bottle, and the cover having a fixed tube passing to the cover and a penetrating hole formed on the cover, and the penetrating hole having a movable tube capable of moving up and down for adjustment, and the water supply bottle being inverted, such that the cover is installed to the well, and the fixed tube, the movable tube and the ventilation tube are situated in the well.

A system for growing plants, the system may include a substrate having one or more weakened areas or openings: one or more grow portions coupled to the substrate and situated at the one or more weakened areas or openings and having at least one seed or plant; and/or a fluid distribution portion coupled to the substrate and configured to provide fluid to the one or more grow portions. The system may further include a method of operation including one or more acts of: obtaining a weather forecast for a future time period; determining whether rain is expected during the future time period; and preventing, terminating, or restricting an irrigation cycle when it is determined that rain is expected during the fare time period. The restricting may restrict a flow of liquid during the irrigation cycle or shorten the irrigation interval.

Aspects of the disclosure relate to a hydroponic apparatus (10) and to methods of use of the same. The apparatus (10) comprises a reservoir (12) for a liquid, a growth vessel (14) for a plant and an air supply (22). A tank (20) is disposed in the reservoir (12). The tank (20) is in fluidic communication with the reservoir (12), with the growth vessel (14) and with the air supply (22). The tank (20) comprises an inlet valve (Vi) for allowing liquid in the reservoir (12) to enter the tank (20) and an outlet valve (Vp) for allowing air in the tank (20) to vent to atmosphere. The apparatus (10) further comprises a controller (23) for activating and deactivating the air supply (22).

An apparatus and method to regulate the fluid level in a plant watering device is described. In an embodiment, the plant watering device comprises a fluid reservoir that is supported by an adapter/fluid regulator that sits within a hollow permeable plant stake. The plant stake is designed to be pressed into soil adjacent to a plant growing in the soil. The adapter sits within the plant stake and acts as a valve with multiple settings that control the depth of water in the plant stake. Exposing the permeable plant stake to various levels of water affects the rate of permeation through the stake and thereby regulates the watering rate for the plant.

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.

The present invention proposes a device for controlling discharge by a conduit. The device comprises a body, a mouth or a first portion attached to the body and a needle or a second portion attached to the body. The mouth and the needle are coaxial. The mouth receives an end portion of the conduit, such that when Areceived, an internal surface of the mouth is in contact with an external portion of the end portion of the conduit. The needle is arranged to be inserted into the received end portion of the conduit, such that an external surface of the needle is in contact with an internal surface of the end portion of the conduit.

A hydroponic cultivation apparatus, a system and a method for facilitating hydroponic cultivation is disclosed. The hydroponic cultivation apparatus includes a reservoir, a plinth, a grow tray with a grow tray lid, and a docking with coupler. The reservoir, placed upon the plinth, is located at a higher position adjacent to the grow tray for optimizing liquid circulation from the reservoir to the grow tray and vice-versa using one or more pipes, a solenoid valve and a pump. The base further includes a dock coupled to the grow tray for providing an electrical connectivity to the grow tray and simultaneously allowing the liquid to flow through the grow tray without being leaked. Further, the apparatus is having a roof which is provided with sources of illumination for providing light required for plant growth.

An automated outdoor modular vertical plant cultivation system forming a vertical structure is provided. The system includes a plurality of shelves, each shelf having a web and flanges; two posts, each post having a web and flanges. Each shelf of the plurality of shelves is mounted between the two posts with incremental spacing between each adjacent shelf along a vertical length of the two posts. The web of each shelf includes a plurality of openings for retaining planter vessels. The flanges of each shelf retain an embedded structural member. The system includes a fluid circulatory system including shelf irrigation piping extending longitudinally above the web of each shelf; and power or power and data and fluid members for the system distributed from vertical risers located in proximity to the web of the posts, wherein the flanges of the shelves have provisions to retain the fluid circulatory system.
