The Whitney Greenhouse is available in the 12′ x 18′ and 12′ x 24′.    A first-class greenhouse at an affordable price, the Whitney Premium Grower’s Edition Greenhouse is a professionally-made structure for growers looking for quality and simplicity to grow their crops within a controlled environment. With a 12 ft. width, side walls at 8 ft. high an interior center peak of 11.5 ft, and lengths of 18 ft. and 24 ft., the Whitney Premium Grower’s Edition Greenhouse provides abundant space for your crops of choice.

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.

Each Whitney Premium Grower’s Edition Greenhouse includes upgraded light-diffusing 8 mm twin-wall polycarbonate wall and roof panels, which allow more light to be used during the growing process, saving energy. 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. All of our Educational Grower’s Edition Greenhouses use built-to-last construction along with a climate-controlled environment to provide stability and efficiency for many years of use.
