Hello Sir,
What is the type of soil??? You have mention about the place but not given details of soil condition and source of water available nearby. Greenhouse cultivation is possible . The crop you choose depends upon the soil condition and water availability.
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
You can approach the Horticulture department in Allepey, the horticulture officer will guide you.

Ashwini S
