The Portable Fold-Down Greenhouse consists of 6-mil clear plastic attached to a galvanized steel frame (with anchor units) that can be opened during the day when temperatures rise and closed at night or with inclement weather. The greenhouse features a hinge design and pulley system with spring-loaded latches and handles for opening/closing. Four models are available: the 9' x 17' x 8' GardenPro and the 9' x 12.5' x 6.3' GardenArch, which are stand-alones, plus the 9' x 8.5' x 8' SouthSider and the smaller SouthSider Jr., which attach to the side of any building. Benches and shelving are among the optional accessories.
