Mount Auburn’s new Greenhouse, a 9,500 square-foot facility comprised of four adjoining glass-houses exemplifies cutting-edge greenhouse construction. Among its many features are open-roof venting, side-wall and ceiling curtains, high-efficiency boilers for radiant floor heating to create the most energy-efficient climate-controlled environment, and a below-ground 30,000 gallon cistern for collecting rainwater from the greenhouse roofs to irrigate growing plants.
