ABSTRACT:
Solar radiations having longer wavelengths than those which are useful for plant development are selectively absorbed by an optical filter formed by two transparent walls which constitute at least part of the roofing structure of a greenhouse or "lean-to" frame and by a heat-transporting fluid which is circulated between the walls in a closed-circuit system. The heat absorbed is removed and stored in a separate reservoir, then recovered at night by pumping and circulating the fluid so as to maintain a predetermined minimum temperature within the greenhouse.
