Hydroponics
Hydroponics is the
method of growing plants without soil, using mineral nutrient solutions in water.
The containers are made of glass, metal or plastic. They range in size from
small pots for individual plants to huge tank for large scale growing. It was
demonstrated by a German Botanist Julius Von Sachs in 1980. Hydroponics is
successfully employed for the commercial production of seedless cucumber and
tomato. Plants are suspended with their roots submerged in water that contain
plant nutrients. The roots absorb water and nutrients, but do not perform the
anchoring function. Therefore, the plants must be mechanically supported from
above.
