GM Greenhouses

A structure covered under transmitting material is called a Green house. These structures are further classified on the basis of its transmitting material. In olden days these were constructed on wooden frames where glass was used as a covering material, which were then known as glass houses. On advent of plastic technology, it became possible to replace glass with plastic material. Polyethylene material, being the most popular, the greenhouses came to be known as polyhouses in recent times. Around this time, even timber availability became a crucial issue. It became possible to use G. I. or M. S. to replace timber. Thus the modern greenhouses normally are built on steel frame, when covered with polyethylene is called poly house and when covered with Fiber Glass Reinforced plastic is called plastic house. Nowadays an advanced material called Polycarbonate is being used as a transmitting material.

Hence, cultivation under this structure remains protected from wind, rain, radiation, precipitation etc. It is possible to create favorable climatic conditions in order to improve the quality and its optimum production. Besides these one of the major advantages is that, due to the enclosure CO2 is stored in it at night and can be used by the plants in the morning during photosynthesis.
