Hi Sreperu,
The subsidy for polyhouses from government varies from state to state.
Cost involved for the construction:
1 Less expensive polyhouse without fan - Rs.300 to 500/m2
2 Medium cost polyhouse with pad and fan system (without automation) - Rs.800 to Rs.1100/m2
3 Expensive polyhouses with fully automatic (control system) - Rs.2000 to Rs.3500/m2
