Hello Sir
I think u should go for Low cost greenhouse which 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.

or u may also think of Medium-tech greenhouse which 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

Polyhouse is further divided in to two types
a) Naturally ventilated polyhouse
These polyhouse do not have any environmental control system except for the provision of adequate ventilation and fogger system to prevent basically the damage from weather aberrations and other natural agents.

b) Environmental controlled polyhouse
This type of polyhouse helps to extend the growing season or permits off-season production by way of controlling light, temperature, humidity, carbon-dioxide level and nature of root medium.




Cost of greenhouse
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
