Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. 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. Water culture became a popular research technique after that. In 1929, William Frederick Gericke of the University of California at Berkeley began publicly promoting that solution culture be used for agricultural crop production. He first termed it aquaculture but later found that aquaculture was already applied to culture of aquatic organisms.
