Polytunnel / Polyhouse farming
Poly house farming is cultivating crops under protected conditions. It can provide higher temperature and/or humidity than are available in the environment. The polytunnels/polyhouses can also protect crops from intense heat, bright sunlight and strong winds. This helps the crops to grow on all seasons. Every factor influencing a crop can be controlled in a polyhouse.
Government provides good amount as subsidy for polyhouse farming. A person having 20 cents of land can start hi-tech farming where the polyhouse will come up in 10 cents of land and the rest of the land for supporting the cultivation A polytunnel (also known as a polyhouse, hoop greenhouse or hoophouse, or high tunnel) is a tunnel made of polyethylene, usually semi-circular, square or elongated in shape. The interior heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. Temperature, humidity and ventilation can be controlled by equipment fixed in the polytunnel.
The polyhouse technologies are advanced in Israel, Holland, Spain, Italy, Kenya, South Africa, Japan and China. But unfortunately much neglected in India
