ABSTRACT:
A plurality of inflatable clear polyethylene tubes extending in spaced adjacent relationship longitudinally across a greenhouse at the eave level. A regulatable blower is arranged to deliver or evacuate air from a manifold which is in communication with each of the tubes. Operationally, the tubes are inflated to bear against each other and form a barrier for heat when sunlight is absent and are deflated to provide passages when sunlight is available.
