A low mass method of growing plants.
Aeroponics, like hydroponics, is a technique for growing plants without the use of soil. It has long been known that plants absorb nutrients as simple ions in water and that soil only acts as a reservoir for the nutrients and water. If the nutrient levels of a plant's water supply is artificially maintained and the water directly applied to its root system, soil is no longer required for the plant to thrive. In the aeroponic method, water is applied as a mist to the root system of the plant.
