What is hydroponics? A perfunctory search of the internet produces all manner of explanations, from historical accounts of a Roman emperor’s cucumbers to futuristic images of modern theme park gardens. Less considered is the actual science that underpins why growing plants without soil is even possible, which is precisely what hydroponics does.
Contrary to conventional wisdom, plants do not need soil to grow. The basic requirements for plant life are light, an adequately warm environment, water, carbon dioxide, oxygen and mineral nutrients. In his early 1600s experiments, Jan Baptist van Helmont revealed that plants do not consume soil to grow and increase in weight. Rather, soil simply acts as a reservoir for some of what plants need, primarily water and nutrients. In 1929, the University of California scientist William Gericke would coin the term hydroponics, which means “water working” in Latin. Gericke’s experiments demonstrated that vegetables grown in such a manner could compete economically with field grown commercial crops.
