Aeroponic growing is unique in that there is no growing medium used. The plant roots grow out of net cups and hang suspended in the air and are kept constantly misted with nutrient.
Clone machines use the Aeroponic concept, but are specifically designed for use in rooting the cuttings of your existing plants. (See complete price list here)
