Greenhouse Technology is the technique of providing favourable environmental condition to the plants. It is rather used to protect the plants from the adverse climatic conditions such as wind, cold, precipitation, excessive radiation, extreme temperature, insects and diseases. It is also of vital importance to create an ideal micro climate around the plants. This is possible by erecting a greenhouse/glass house, where the environmental conditions are so modified that one can grow any plant in any place at any time by providing suitable environmental conditions with minimum labour. Greenhouses are framed or inflated structures covered with transparent or translucent material large enough to grow crops under partially or fully controlled environmental conditions to get optimum growth and productivity. This book provides the information about the greenhouse technology, its design criteria and computer aided drawing of different sizes of greenhouse
