Hidroponia este arta de a creste plantele direct in apa. Cuvantul provine de la cuvintele grecesti "hidros" care inseamna apa, si "ponos" care inseamna munca. Acest concept a fost re-descoperit in anii 30 ai secolului trecut la universitatea Berkeley din California, de Dr. Gericke - si spunem re-descoperit pentru ca in realitate aceasta metoda de cultivare a existat inca din cele mai vechi timpuri.

Hydroponics (from the Greek words hydro water and ponos labor) is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.
