#$%^&*AU2018200792B120180823.pdf#####ABSTRACT An environment controlled multi span structured greenhouse wherein (AL) comprises an artificial light and, or natural light intensifying and magnifying system to achieve a defined optimal level (pmol m-2 -1) which optimizes photo periods and utilizes greenhouse and the bio-thermal harnessed carbon dioxide thereby further reducing global warming. (A1) comprises two blowers, a compressor, a capture manifold, two dehumidifying tanks, and a release manifold. (A4) comprises single bio-thermal energy harnessing tank; (A6) comprises activated nutrients solutions of calcium sulphate, of magnesium sulphate and of urea. (A7) comprises a thermal shading film fixed to the roof and to the four external sides of the greenhouse to fully insulate greenhouse from the atmosphere.
