Hydroponics: Definition, History, Types, and Scope in Indian Agriculture

A method of growing plants using mineral fertilizer solutions without soil is called Hydroponics (Greek words “hydro” for water and “ponos” for labour). Growing plants hydroponically necessitates controlling environmental variables such as light intensity and duration, temperature, humidity, pH of the solution/medium, and mineral nutrients. This is why it is also known as “controlled environment agriculture” (CEA). Hydroponics refers to the practice of growing plants without soil.
