Improvement in and relating to environment controlled structured green houses for cost effective food production

摘要

The present invention relates to the environment controlled multi span structured greenhouses comprises modules Z1 to Z7 and a plurality of sensors. Z1 comprises a compressor, tanks T1, T2 and Ta, a capture manifold and a release manifold, Z2 comprises a low cost earth tube heat exchanger for low cost heating of the greenhouse in colder locations (substantially reducing crude (fossil fuel) use) and supplements cooling in hotter locations, Z3 maintains greenhouse air relative humidity at defined relative humidity point, Z4 harnesses biothermal energy, Z5 alleviates global warming by preventing the greenhouse carbon dioxide being released into the atmospheres, Z6 uses activated nutrient solutions to substantially reduce input costs of nutrients in drip and foliar dosing, Z7 comprises a polyethylene film fixed on the roof and four external sides of the greenhouse, and a 0(close)-100%(open) roll automated thermal and shading curtains which eliminates the need for gutters which increases sunlight into greenhouse, and improves integrated pest management.
