If your grow system includes a hydroponic reservoir, utilising an air pump and air stone in the bottom of the tank to keep the solution thoroughly mixed and fully oxygenated can be quite beneficial. Both plant roots and the helpful microorganisms that thrive in the root zone enjoy oxygen. You can aid to maximise root growth and health by employing an air pump and air stone. Most forms of hydroponic grow systems need a water pump to provide the nutrient solution to the plants, making them an essential component.
