Abstract
The specification discloses a hydroponic nutrient aeration and flow control (NAFC) device and system, which both aerates and controls the flow of the hydroponic nutrient solution. The NAFC device has no moving parts. Each NAFC device mixes and aerates the nutrient from the nutrient reservoir with air and/or nutrient from one of the grow tanks. Each NAFC device additionally controls the flow of the aerated nutrient solution to the grow tank and the nutrient reservoir. The vertical position of the end of the nutrient return line in each grow tank may be adjusted to adjust the level of the nutrient solution within the grow tank.
