The Riverstone 12 ft. x 18 ft. Thoreau Premium Educational Greenhouse is designed for schools with correctional institutions, horticulture programs, and serious gardeners for both growing and therapeutic reasons. The 2 in. x 2 in. galvanized steel frame with pre-welded stanchions and commercial-graded 8mm twin wall corrugated covering (walls and roof) has the same specifications used in commercial products on the market today. The walls and roof are warrantied for 10 years and have a 15 to 20 year life expectancy. The Thoreau Greenhouse is named after the great naturalist and agriculturalist Henry David Thoreau. The walls of the Thoreau are 6 ft. tall with a center peak of 9-1/2 ft. for optimal air circulation. The design of an Educational Greenhouse is different from that of hobby or commercial greenhouses. These differences include: being able to accommodate large numbers of people, providing a secure environment that can be locked when not in use, and having sturdy construction that will last for years of use. These features are all within a climate-controlled environment that is thermostatically controlled.
