A solar heating collector is employed in the form of a plenum constituted of the greenhouse translucent roof and a roof floor of black plastic sheeting. Hot air from the plenum is distributed by air directing means to a heat storage chamber in a charge cycle or directly to the greenhouse in a direct heat cycle. In a discharge cycle air from the greenhouse is directed through the heat storage chamber to be heated and discharged into the greenhouse. Specially designed collapsible tubes are employed in the system for distribution of exhaust air and distribution of heated air from a manifold. The heat storage chamber employs cylindrical containers of a phase change material to store solar energy and serves to support the air directing means and the aforementioned collapsible tubes to provide a central unit for providing and monitoring solar heat distribution.
