A greenhouse construction and method of growing plants in cold climates employing a water layer defining in part a growing environment which transmits solar radiation into the interior of an enclosure constituting the growing environment. The water layer acts to absorb longer wavelength infrared portions of the solar spectrum preventing overheating of the greenhouse interior during cold and warm weather seasons, with the resultant heating of the water in the layer allowing it to act as a thermal storage medium during cold weather seasons. At the same time, the water layer transmits the photosynthetic shorter wavelengths of the solar spectrum to support plant growth within the greenhouse. The water layer is disposed in a ceiling structure, consisting of spaced transparent sheet layers combined with a pivotal reflector-insulator panel acting to cover the water layer during nighttime or other periods when solar radiation is absent or minimal. The water in the water layer optionally is circulated through an irrigation system after being warmed by the solar radiation.
