Hydroponics

In hydroponics, plant roots receive water containing dissolved mineral ions. The grower can control the mineral supply instead of depending on the quality of the local soil. This can allow crops to be grown where soil is poor or other conditions are difficult.

In hydroponics, crops are grown without soil and their roots receive water containing dissolved mineral ions. In a glasshouse, growers can also control conditions such as temperature carefully. Supplying suitable conditions helps plants grow efficiently and makes production less dependent on the quality of local soil.
