Hydroponics is a method of growing plants using mineral nutrient solutions instead of soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as gravel or mineral wool. A variety of techniques exist and almost any terrestrial plant will grow with hydroponics, but some will do better than others.
