A watering system including a receptacle including a fluid flow generator and a fluid flow generator controller which releasably couples to a fluid reservoir containing a fluid which can be transferred by operation of the fluid flow generator from the fluid reservoir to a plurality of fluid flow meters which can be disposed in spaced apart relation to correspondingly deliver the fluid to a plurality of spaced apart locations. In particular embodiments, a plurality of potted plants can be disposed in spaced apart relation and one more of the plurality of fluid flow meters can be correspondingly located to deliver the fluid to each of the plurality of potted plants.

The invention concerns a plant cultivation device. The device comprises a receptacle having at least one peripheral wall and a bottom wall. The bottom wall has at least one hole opening into an irrigation tube, a region of the bottom wall around the, or each, hole comprising guide means adapted to guide roots of a plant around the corresponding hole to keep the irrigation tube substantially clear.

The invention also concerns a cartridge comprising a substrate, adapted to be positioned in this receptacle, the cartridge having a lower face comprising at least one relief adapted to cooperate with the guide means of the receptacle.

A submersible member can include an elongated body defining an outer body surface, the body defining a top end and a bottom end; a base electrode extending through the outer body surface; a first conductive member extending through the body from the top end to the base electrode, the first conductive member connected in electrical communication with the base electrode; an indicator electrode extending through the outer body surface, the indicator electrode positioned between the top end and the base electrode; and a second conductive member extending through the body from the top end to the indicator electrode, the second conductive member connected in electrical communication with the indicator electrode.

A grow system. The system includes growing plants in grow modules that are individually moveable. The plants grow in trays where roots never touch the water supply. The plumbing to the grow modules is a low flow, one way flow continual drip system that is hands free. A mobile robot can navigate around a growspace, bring any grow module from one location to another, and perform growspace operations. The growspace is a control space with data source zones and a control space manager. The control space manager can collect data and control different variables across different data source zones in order to determine optimal policies and conditions for data source growth and generation.

An automatic plant watering device includes a thermoelectric module with a cold face that can be energized to drop its temperature below 32 degrees F. A condensation member is thermally connected to the cold face and has a wall exposed to ambient air for water vapor to condense on and freeze when the module is energized. A water collection chamber positioned below the exposed wall is configured to hold collected melt water from the exposed wall until a collected melt water temperature has risen above 32? F. A moisture sensor is used to initiate a chilling cycle controlled by a controller to energize the thermoelectric module for a period of time in excess of an hour to cause a build-up of frost on the exposed wall and thereafter to deenergize the thermoelectric module to permit the temperature of the exposed wall to rise above 32 degrees F.

A plant cultivating apparatus according to an embodiment of the present disclosure includes a main body, a shelf, a cultivation bed, and a cultivation container. The shelf is disposed in the cultivation space formed in the main body, the cultivation bed is disposed on the shelf, and the cultivation container is seated in the cultivation bed. The cultivation bed includes a water supply part for receiving a predetermined amount of water. In addition, the shelf includes a water level sensor. The water level sensor is positioned vertically below the water supply part to measure an amount of water stored in the water supply part.

A plant water pot that automatically provides regular water to a plant and indicates a reduced water level. The plant water pot includes an inner wall that terminates at a lower end of a platform defining a receptacle in communication with an upper opening of the container. An interior volume is defined between the inner wall and the outer wall, while the interior volume retains a fluid. Nozzles are disposed about the inner wall and the nozzles are in fluid communication with the interior volume. A pump is disposed within an interior volume and is operably connected to each of the nozzles. An inlet is disposed through the upper wall and the inlet provides access to the interior volume.

A flow-through oxygen infuser which is an assemblage of one or more venturis, in a chamber, is disclosed. When a venturi(s) is placed in an airtight chamber and water is passed through the venturi(s) a negative pressure is formed in the airtight chamber; additionally a minimal amount of pure oxygen is injected into the chamber generating very small bubbles of oxygen in the water passing through the venturis. The very small oxygen bubbles remain in suspension forming a solution supersaturated in oxygen. A flow-through model for infusing water with oxygen is disclosed. The use of supersaturated water for enhancing the growth of plants is disclosed. Methods for applying supersaturated water to plants in hydroponic culture are described. The promotion of beneficial aerobic bacteria with supersaturated water is described.

The hydroponic cultivation apparatus (1) of the present invention includes a container (10), a cover (50), a nutrient solution supply unit (20) for supplying a nutrient solution (W) to a hollow portion (12s) of the container (10), and a water level adjuster (60). The container (10) is formed in a tubular shape. The cover (50) has a size such that the cover (50) can protect rhizosphere (R) and cover the opening (14) of the container (10). The water level adjuster (60) is connected to the container (10) and enables adjustment of the water level of the nutrient solution (W) in the hollow portion (12s).

A rotary garden apparatus, method and system for growing plants comprising an open rotatable cylindrical drum mounted within a structural frame is provided wherein said apparatus comprises an accessible front area permitting access to the drum and grow trays mounted on said drum from the front of the apparatus. The rotating drum portion comprises metal bars which form struts round the periphery of the drum on which grow trays can be mounted. The grow trays are inserted by sliding them along the struts of the drum and they are held in position by arms which extend below the metal struts over which the grow trays slide into position. The inverted T shaped fit between the tray and the strut holds the tray in position during rotation without further securing mechanisms required. The operation and most routine maintenance of the apparatus can all be done from the front of the apparatus thereby permitting multiple apparatus units to be placed side by side in a grow facility or against walls. The apparatus may be stacked one above the other all of which maximizes the number of units which can be present in a defined floor space in a grow facility. A light source comprising a holding tray, a sleeve and at least one bulb as part of a rotary garden apparatus is present in the rotary garden apparatus providing light for growing plants.
