The Monticello 12 x 8 ft. Greenhouse proves that not all hobby greenhouses are built the same. Most greenhouses on the market use cheap wall and roofing materials. The made-in-the-USA Monticello, on the other hand, uses the highest-grade aluminum framing available for ultimate durability against the elements. Its light-diffusing panels, made from professional-grade 8mm twin-wall polycarbonate, act to keep cool air in during warm months while also insulating the green house during winter months. Other highly convenient features include a 24 square foot folding work bench, a drip irrigation system with 48 dripper heads, programmable timing, and an electric exhaust fan system with a commercial thermostat. Double doors provide entry and exit on either side of the greenhouse. 2 automatic roof vent openers round out the list of premium and loaded features. Grow your favorite greens for years with the hassle-free ingenuity of the Monticello Greenhouse.
