Aeroponic systems are a distinct type of hydroponics. The plant roots grow out of net cups and are hanging in the air. They are regularly misted with the nutrient solution to keep them moist.
Increased aeration of nutrient solution delivers more oxygen to plant roots, stimulating growth while preventing algae formation.
Cloning machines use the Aeroponic concept, but are purposely set up for propagating the cuttings of your current plants.
