The invention is a method and a system that use a distributed reservoir sub-system to maintain root temperatures in a modularized aeroponics setup. The reservoirs integrate with root chambers. Thermo-insulation materials and active temperature control functions are used to maintain temperatures of the nutrient reservoirs. Liquids in the reservoirs are further used as a media to maintain root chamber temperature and to reduce the fluctuations caused by pressurized nutrient delivery.

The potted plant system of the present invention uses the space between the inner and outer pots as a reservoir for water. The water reservoir acts passively to transport water into the spoil of the inner pot which is subsequently used by the potted house plant. The reservoir is filled by over watering the inner pot and allowing the excess water to pass through the apertures within the inner pot. Passive transport of water from the reservoir to the soil occurs as the water saturation of the soil decreases. As a result, the soil and the potted plant remain hydrated for longer period of time as the reservoir continuously replenishes the water. The water within the reservoir can be drained through a quick connect sliding valve located on the outer pot. The quick connect sliding valve is either placed above another water receptacle or is fitted with a hose that transports the water to a drain.

A smart home gardening cabinet is disclosed that includes a plurality of plant growing drawers each having a vertical lift door and an automatic precision weather system to grow a specific type of plants, each automatic precision weather system includes an array of lights for photosynthesis, an air circulation system, and a water circulation system that provides nutrient water to the specific plants in each plant growing drawer; each plant growing drawers having a plant growing tray that includes an array of growing holes filled with a sponge materials to absorb and retain nutrients which are misted to the roots of the plants, excess nutrient water being returned to the water circulation system to save water.

An apparatus for planting a seedling (3) in an arid area comprises a vertical, downwardly tapering shroud (20) and a seedling plug (1) comprising a body of growing medium covered by a moisture resistant cap (14) which preferably is sealingly received in a lower region (22) of the shroud. The lower region of the shroud surrounding the upper portion of the seedling is buried beneath ground level (51) with at least one water reservoir (40, 200) and supplied with water via capillary wicks (43), the reservoir being buried beneath ground level and covered by a moisture resistant cover (60) which sealingly surrounds the shroud. The shroud extends above ground level to protect and shade the seedling and together with the cap (14) and cover (60) serves to retain moisture in the planting region for the first year of growth.

A flexible water dispensing reservoir is provided. The device includes a flexible reservoir having a first end wall, a second end wall, and a plurality of sidewalls, defining an interior volume. A ventilation aperture and an inlet aperture are disposed through one of the plurality of sidewalls. A plurality of nozzles are disposed on one of the plurality of sidewalls. The ventilation aperture, the inlet aperture, and the plurality of nozzles are in fluid communication with the interior volume. A pump is disposed within the interior volume, wherein the pump is operably connected to the plurality of nozzles. When the pump is actuated, fluid disposed within the interior volume is dispensed through at least one of the plurality of nozzles. In some embodiments, a controller housing is in communication with the plurality of nozzles via a wireless transceiver, wherein the plurality of nozzles dispense fluid according to a programmed schedule.

A grow box comprises a box body and a cover which are matched with each other; a planting unit arranged on the grow box for planting plants; a nutrient solution supply unit comprising a nutrient solution storage chamber and an atomizer, and the nutrient solution is supplied to the roots of the plants under the condition that the plants lack nutrient solution, wherein the nutrient solution storage chamber is constructed as a part of box body space which is separated from the box body by a partition plate. The present invention further discloses a plant grower using the same grow box with a supporting device. In addition, various sensors are arranged in the grow box and the plant grower to perform automatic induction without the need of manual operation, so that the pleasure and the simplicity of planting are enhanced.

An aeroponic plant-growth system includes growth space and a control unit that may be assembled using factory made modules. The growth space includes layers at different heights, and each layer includes plant holders and misters positioned to apply a mist to roots of plants in the plant holders. The control unit employs a controller to execute a program that operates a liquid supply system to provide liquid flows to the misters in the layers. Each of the liquid flows may be regulated according to the height of the layers.

A plant holder for a hydroponic system includes a first structure shaped to hold a plant during an early growth stage and a second structure configured to hold the first structure during a later growth stage. The first structure is sized to directly fit in a tray having a high plant density. The second structure is sized to directly fit openings in a tray having a lower plant density. Plants in early stages of growth may be efficiently grown with the first structures in the high-plant-density tray, and the first structures with the plants may be easily transferred to more spacious trays without damaging the plants.

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 sensor, such as a hydrostatic water level sensor, includes a pressure sensor, a vent, a vent tube connecting the vent to the pressure sensor, and a fabric covering the vent. The pressure sensor is submersible in a liquid to be measured and the vent is configured to be outside the liquid. The fabric covers the vent and is both waterproof and breathable, e.g., Gore-Tex. The vent may be integrated into an electrical connector for the pressure sensor, and the electrical connector may provide IP-65 protection. The sensor may be particularly be employed in an aeroponic plant growth system where the fabric prevents mist from blocking the vent and/or vent tube.
