Hello Durga naidu,
Green houses are climate controlled. Jain Green Houses have a variety of applications, the majority being, off-season growing of vegetables, floriculture, planting material acclimatization, fruit crop growing for export market and plant breeding and varietals improvement. In conventional Agronomical practices, the crops are being grown / cultivated in the open field under natural conditions where the crops are more susceptible to sudden changes in climate i.e. temperature, humidity, light intensity, photo period and other conditions due to which the quality, yield of a particular crop can get affected and may be decreased. Green Houses are available in different sizes and constructed as per customer requirement. The sizes vary from as small as 100 Sq. M to 10,000 Sq M and more.

Financial subsidy is provided by NHM. YOu can approach the officer in your district for details. YOu can also avail bank loan. The cost of construction varies depnding on the type of greenhouse you want to erect.
a) Low cost or low tech greenhouse
Low cost greenhouse is a simple structure constructed with locally available materials such as bamboo, timber etc. The ultra violet (UV) film is used as cladding materials. Unlike conventional or hi-tech greenhouses, no specific control device for regulating environmental parameters inside the greenhouse are provided. Simple techniques are, however, adopted for increasing or decreasing the temperature and humidity. Even light intensity can be reduced by incorporating shading materials like nets. The temperature can be reduced during summer by opening the side walls. Such structure is used as rain shelter for crop cultivation. Otherwise, inside temperature is increased when all sidewalls are covered with plastic film. This type of greenhouse is mainly suitable for cold climatic zone.
b) Medium-tech greenhouse
Greenhouse users prefers to have manually or semiautomatic control arrangement owing to minimum investment. This type of greenhouse is constructed using galvanized iron (G.I) pipes. The canopy cover is attached with structure with the help of screws. Whole structure is firmly fixed with the ground to withstand the disturbance against wind. Exhaust fans with thermostat are provided to control the temperature. Evaporative cooling pads and misting arrangements are also made to maintain a favourable humidity inside the greenhouse. As these system are semi-automatic, hence, require a lot of attention and care, and it is very difficult and cumbersome to maintain uniform environment throughout the cropping period. These greenhouses are suitable for dry and composite climatic zones.
c) Hi-tech greenhouse
To overcome some of the difficulties in medium-tech greenhouse, a hi-tech greenhouse where the entire device, controlling the environment parameters, are supported to function automatically.
Cost involved
1. Less expensive greenhouse without fan and pad Rs.300 to 500/m2
2. Medium cost greenhouse with pad and fan system Rs.800 to Rs.1100/m2
without automation
3. Expensive greenhouses with fully automatic Rs.2000 to Rs.3500/m2
control system
