Hydroponics is a subset of hydroculture, which is a method of growing plants without soil by using mineral nutrient solutions in a water solvent.

History of agriculture

Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients used in hydroponic systems can come from an array of different sources.

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).The word "aeroponic" is derived from the Greek meanings of aer (ἀήρ, "air") and ponos (πόνος, "labour").
