A green house is a framed structure covered with glass or UV stabilized polyfilm where crops could be grown under partially or completely controlled environment. The transparent cladding material allows the solar radiation to enter in the green house generally remains 10-150C more than outside even during winters. A Green house permits round the year cultivation and growing off season vegetables in hilly regions even during winters and helps in supplementing the income of farmers. It is found that the yield in the green house is five to six times higher than in open fields. The crops mature faster. In high altitude regions the growing season can be extended. An attached green house can also be used for space heating of houses during winters.
