The Thoreau Greenhouses is available in the 12′ x 18′ and 12′ x 24′.   Gardeners looking for a professional structure with a controlled environment for their crops should look no further than the Thoreau Premium Grower’s Edition Greenhouse. The cheapest in our line of Educational Grower’s Greenhouses, the Thoreau Premium Grower’s Edition Greenhouse provides growers ample space for greater yields and like all Educational Grower’s Greenhouses, includes a 2 in. x 2 in. galvanized steel frame with pre-welded stanchions and 8 mm light-diffusing twin-wall polycarbonate wall and roof panels, which distribute light better, and allow more light to penetrate and be used during the growing process, saving energy which would be needed for a separate lighting system. For crops that require up to 18 hours of light a day, an additional lighting system can be installed, such as our Genesis ProMax GL600 or GL1200 grow lights.

Special features include a large, locking French door, motorized shutters for greater air circulation, an 18 in. industrial exhaust fan, two commercial-grade work benches, an electric heater with built-in thermostat, an external shade cloth that blocks 63 percent of sunlight to help control internal temperature, and an automatic watering system with timer to take the hassle out of daily watering.

The Thoreau Greenhouse is named after the great naturalist and agriculturalist Henry David Thoreau.
