It is a widespread myth that hydroponics was used by the ancient
Babylonians. There is no evidence they did. The mineral nutrient
solutions required in hydroponics were not developed until the 1860s.
The term hydroponics was not introduced until 1937. William Frederick
Gericke proposed the idea of hydroponics in 1929 but originally called
it aquiculture. The origin of hydroponics is relatively recent.
Maybe the following statement is true in the U.K. but not everywhere.
"Hydroponics growing techniques are responsible for the commercial
supply of nearly all tomatoes, peppers, herbs and cucumbers, most
strawberries and most of the flowers that you see available on the high
About half the fresh market tomatoes in the U.S. are hydroponic but
almost all canned tomatoes and those in soup, pizza sauce, ketchup,
etc. are grown in soil. Relatively few strawberries are grown
hydroponically in the U.S. Most greenhouse cut flowers are grown via
soilless culture, but that is not the same as hydroponics. Hydroponics
is used for relatively few food crops, not "many", mainly just the few
specifically mentioned, fresh tomatoes, fresh peppers, fresh herbs,
fresh cucumbers, a little fresh lettuce and some strawberries. Tree
fruits do not lend themselves to hydroponics. Most vegetables are
cheaper to grow in soil as are grains, beans and potatoes.
Hydroponics is currently an economic cropping method for only a few
