The Monticello 8 ft. L x 8 ft. W Black Backyard Greenhouse is constructed from the highest quality extruded aluminum and electrostatically painted black. Guaranteed to contain 0.0% lead. The MONT uses professional grade 8 mm twin wall polycarbonate, the same thickness as used in commercial greenhouses. The twin wall polycarbonate acts as a double pain window keeping cooler air in during warm months and insulating the greenhouse in the wintertime. This makes the MONT more efficient to grow in for a longer period of time and adds to the efficiency of growing, cutting down electric bills. At 7 ft. 6 in. tall at the peak the MONT's above average interior height design helps with displacing heat within the greenhouse. From the integrated base to the built in rain water gutter system, to the automatic roof vent opener and to the newly redesigned hinged double doors with an opening of almost 6 ft. high x 4 and 1/2 ft. wide This is a Premium Package, which includes the MONT Greenhouse, one side of Commercial Work Benches, Interior Shade System, Programmable Watering System, and Greenhouse Sink. Backed by a 10 year limited warranty on frame and polycarbonate.10 year limited warranty on the frame and polycarbonate
