The Snap-and-Grow Hobby Greenhouse Kit consists of the following components: galvanized-steel base to be anchored to a wood or concrete foundation; corrosion-resistant, aluminum frame secured with the SmartLock connection system; SnapGlas side and roof panels, which are clear, UV-stabilized; and adjustable roof vent (or vents, depending on length of the structure). The structures are flat-box-shipped to be assembled by the purchaser. A total of five models are available: three that are 6 feet wide and 6, 8, and 12 feet long; two that are 8 feet wide and 8, 12, 16, and 20 feet long. The larger ones come with ramp-style thresholds to provide access for wheelbarrows or wheelchairs.
