context_page_description: Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium. The word "aeroponic" is derived from the Greek meanings of aer and ponos. Aeroponic culture differs from both conventional hydroponics, aquaponics, and in-vitro growing. Unlike hydroponics, which uses a liquid nutrient solution as a growing medium and essential minerals to sustain plant growth, or aquaponics, which uses water and fish waste, aeroponics is conducted without a growing medium. It is sometimes considered a type of hydroponics, since water is used in aeroponics to transmit nutrients.
context_section_description: Aeroponics possesses many characteristics that make it an effective and efficient means of growing plants.
