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.

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 self-contained air filtration system is disclosed herein. The system includes a processor. The processor can receive data from one or several components of the system and can provide control signals to one or several components of the system. The system can include a housing. The housing can include: a reservoir portion; and a greenhouse portion. The greenhouse portion can connect to the reservoir portion via a grow tray. A top of the reservoir portion and the greenhouse portion define an enclosed volume. The greenhouse portion can include an inlet aperture and an outlet aperture. The inlet aperture can be obstructed by an inlet filter such that air flowing into the greenhouse portion passes through the inlet filter, and the greenhouse portion can be connected to a fan that can propel air through the inlet aperture and out of the outlet aperture.

The present application discloses a self-watering pot base comprises a pot base, a lid and at least one absorbent. The lid is removably coupled to the pot to form an accommodation space, the lid comprises at least one leaking hole and at least one absorbent hole. The at least one absorbent passes through the at least one absorbent hole to reach the accommodation space. A method of using the aforementioned self-watering pot base is also disclosed, comprising coupling the lid and the pot base; and locating a fabric pot onto the lid.

The present invention provides a water-retaining layer for retaining water in soil, the water-retaining layer being composed of a coagulated natural rubber latex; a greening system having the water-retaining layer provided; and a construction method of the greening system, comprising: an exposing step of removing surface soil in a construction target land and exposing underground soil, a spraying step of spraying a natural rubber latex on an exposed surface of soil, a coagulation step of coagulating the natural rubber latex to form a water-retaining layer, and a covering step of covering the water-retaining layer with the removed surface soil.

A plant pot or a plant pot insert includes a water filling chamber having a fill opening to receive water, a water outlet to provide water to a water reservoir, and an overflow conduit to discharge excess water through a weep hole on a sidewall of the plant pot. The water reservoir provides water to a root system of a plant to be grown in the plant pot by capillary action. A water level sensing unit detects a water level of the water reservoir.

A fertigation system comprises: a controller that transmits sensor data to a fertigation control server, and that controls a water supply valve, a culture stock solution supply valve, and a discharge valve on the basis of received data; and a fertigation control server that, on the basis of the sensor data received from the controller, calculates control amounts for the water supply valve, the culture stock solution supply valve, and the discharge valve, and returns the control amounts to the controller.

A plant cultivating container includes an outer cup, an inner cup received in the outer cup, wherein the inner cup is provided for cultivating plant(s). A floating plate is movably disposed between the bottoms of the outer cup and the inner cup and a follower is mounted to the floating plate, wherein the floating plate is reciprocally moved relative to the outer due to a water level in the outer cup. At least one window is defined in the outer cup and the follower is formed with a shutter, wherein a relative action is formed between the shutter and the at least one window for providing a continual visual effect.

Assembly line grow pods, watering stations, and seeder components that include robotic applicators are disclosed. An assembly line grow pod includes a tray held by a cart supported on a track. The tray includes a plurality of sections. The assembly line grow pod further includes a watering component providing fluid and a robotic applicator including an articulating robot arm having one or more outlets that selectively dispense the fluid therefrom. The articulating robot arm is positioned to align the one or more outlets with a corresponding one or more of the plurality of sections such that the fluid is dispensable into each of the plurality of sections independently.

An irrigation management system monitors irrigation parameters, including progress of flood irrigation water admitted onto a farm field, water levels in ditches, basins or boxes, soil moisture, water usage and other important factors. In flood irrigation a series of small, inexpensive sensors detect the presence in each of the sensor locations in a field, and each sends a signal when water first reaches the sensor. In a preferred form the sensor communicates by long-range radio communication either directly with a hub or gateway, or by sending a transmission that is relayed from location to location and ultimately to the hub or gateway. All aspects of irrigation water need, availability, task completion, pipe and equipment status, and water usage are monitored and communicated to the farmer. The system allows efficient water management and reliable and responsible irrigation at all irrigated fields.
