The Polycarbonate Greenhouse (8' x 10').

"This greenhouse is made from heat-retaining, virtually unbreakable polycarbonate, providing a superior environment for plant growth. The 4-mm thick polycarbonate is 200% stronger than glass, it filters the sun's harmful UV rays, and maintains a more consistent internal temperature to extend growing seasons and keep plants warm during cold nights. Unlike glass, polycarbonate diffuses sunlight as it enters the greenhouse and distributes it evenly throughout the interior to encourage photosynthesis. The broadsides of the greenhouse have 21""-deep shelves that run the entire length of the walls, providing ample room for pots. A vent on the roof and another next to the door provide air circulation, or the vents can be shut to increase the internal temperature and humidity--ideal conditions for tropical plants. The greenhouse's frame is made from weatherproof powder-coated aluminum. Detailed, easy-to-follow assembly instructions included. Professional assembly recommended. 8' x 10' Greenhouse. 7' 7"" high. (172 lbs.)"
