The present disclosure relates to an irrigation system for irrigating a plurality of plants growing in growing media. The system includes a movable grow table for supporting and displacing the plants and a gravity irrigation device which is coupled to the movable grow table and displaceable therewith. The gravity irrigation device includes a reservoir which is coupled to the movable grow table, a main header in fluid communication with an outlet of the reservoir which is configured to receive a flow of water therefrom, as well as a plurality of microtubes which extends from a plurality of header outlets. The microtubes are configured to receive a head-pressurized flow of water from the main header to evenly irrigate the plants. A method for irrigating a plurality of plants growing in growing media is also described.

The specification discloses a hydroponic nutrient solution aeration device that has no moving parts. The aeration device includes an aerator and a converging nozzle. The aerator includes a nutrient inlet, an air inlet port, and a diverging nozzle. The converging nozzle is adjacent the diverging nozzle. The largest portion of the converging nozzle is connected to the largest portion of the diverging nozzle. The aeration device uses a relatively small volume flow rate to entrain a significant amount of air.

A soil irrigation and restoration system comprises a water transmitting device having a water containing tank, a water pumping element, and a pipe. The water containing tank has a containing space formed therein. The water pumping element is disposed in the containing space and has at least one water inlet, a water outlet, and an overflow portion. The water outlet is spaced apart from the at least one water inlet. The overflow portion is disposed between the at least one water inlet and the water outlet, and is disposed at a position higher than that of the at least one water inlet and the water outlet. The pipe has a connecting end connected to the water outlet. A portion of the pipe away from the connecting end extends downwardly and is buried in the soil layer. A soil irrigation and restoration method executed with syphon effect is also provided.

A system for automated plant condition notification, detection, and watering to improve plant growth and maintenance including a computing unit, an optical sensor, a soil moisture sensor, a water tank level sensor, a pump, and a computing unit. The computing unit includes a memory and a processor that receives a first input indicative of a user identifier and a communication type, a second input indicative of a plant type, a soil moisture input, a water level input, and an optical sensor input. The processor also determines a water pump initiation threshold and a water pump completion threshold based on one or more of the plant type, the optical sensor input, or the soil moisture input and determines a plant maturity optical value based on the plant type. Additionally, the processor transmits a water pump initiation, a water pump completion signal, and a notification via a selected communication method.

A cultivation system for cultivating plants from e.g. seeds, seedlings, cuttings, etc. arranged in or onto substrate plugs (2), comprising a cultivation pot (1) having a bottom wall (4a), a side wall (4b) and filling channel (5) extending upwards from the bottom and/or side wall (4a 4b). Further comprising a filling module (6) provided with a filling connection (7) which is configured to cooperate with the filling channel (5) of the cultivation pot (1) for supplying the cultivation pot (1) with water. The cultivation system further comprises means for measuring the actual quantity of water or the actual water level in the cultivation pot (1), allowing control of the amount of water being supplied.

A water-circulation irrigation system includes a water supply device and a planting device. The planting device includes a water storage container, an irrigation pipeline, a nozzle and a recycling pipeline. One end of the irrigation pipeline is in communication with the water storage container and has a water supply end. The planting device includes a water collection container, a planting tray and a shunting element. The water collection container has a water dispensing post. The planting tray is disposed at an opening of the water collection container. The planting tray has a fitting portion and a through hole and corresponds in position to a water collection space of the water collection container. The shunting element includes a fertilizer chamber and is disposed at the rim of the through hole of the fitting portion. Therefore, a fertilizer solution is produced in a manpower-efficient manner and thus conveniently.

Disclosed herein is a hydroponic system comprising a water container, a gas pump disposed within the water container, and an air chamber disposed around the gas pump. The hydroponic system also includes an air line extending into the air chamber to drive air into the air chamber water within the water container, and an air bell disposed within the water container to capture the air from the air line, wherein the air bell maximizes the surface area of the water with the captured air. Also disclosed is a system and a method for implementing the system.
