Greenhouse is a structure covered with transparent materials such as glass, plastic, fiberglass, whose environmental conditions can be controlled or adjusted in order to provide suitable conditions for growing plants.

In the region where it is established, all kinds of vegetables grown outside under natural conditions and fruit crops that can be considered small in size are cultivated by forcing method under glass or plastic cover. In greenhouse vegetable and fruit cultivation, most vegetables and fruits that were grown only under natural conditions and at certain times of the year are now grown earlier under cover, in greenhouses, with developing technology. This situation naturally has increased the yield and quality of vegetable and fruit growing.
