Hydroponics works under a very simple principle: provide plants exactly what they need when they need it. Hydroponic systems administer nutrient solutions tailored to the needs of the particular plant being grown. They allow you to control exactly how much light the plants receive and for how long.

The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. As a result of his work, water culture became a popular research technique.
