A solar heated greenhouse formed with a rectangular floor having parallel sides and ends, a quonset type roof structure supported above the floor, the roof extending to the floor sides, the roof being formed of an inner and an outer spaced apart light penetrating member, the space between the two members providing a heat collecting chamber, water-filled strata beneath the floor, the heat collecting chamber between the roof members communicating with the strata along each side of the floor, means for spraying water in the heat collecting chamber between the light penetrating member so that the water is heated by solar energy and runs down the chamber and into the strata beneath the floor, and means for recycling water from the strata into the heat collecting chamber whereby water in the strata is heated during sunlit hours and the heat of the water in the strata penetrates the floor and maintains a warm temperature within the greenhouse at night and during sunless days.
