Harvesting rainwater from the top of polyhouses, storing in tanks and using gravity based drip irrigation systems can lead to virtually self sufficiency for water and energy. No external inputs of water or power would be needed.
Value added crops like capsicum could provide returns and a positive cost benefit ratio.
