Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics). Unlike hydroponics, which uses water as a growing medium and essential minerals to sustain plant growth, aeroponics is conducted without a growing medium. However, water is used in aeroponics to transmit nutrients, and therefore is sometimes considered a type of hydroponics.
The use of aeroponic methods is considered safe and ecologically friendly to grow fresh, natural, healthy plants. The main ecological advantage of aeroponics is the conservation of water and energy. In contrast to hydroponics, aeroponics requires less water and energy per square foot of growing area. In commercial operations, where irrigation is an efficient automated system, aeroponic systems use up to 90% less water.
