The aeroponic AeroFlo generates a fine nutrient solution mist to maximize oxygen to the root zone and provide ideal growing conditions. Plants roots grow in the moist air space between the net cups and hang in a shallow, constantly circulating bath of super-oxygenated nutrient solution. By controlling the depth of nutrient solution in the growing chamber, gardeners can maximize moisture supplied to seedlings and cuttings and increase aeration to the roots of mature plants.
