Similar to a shed in the backyard, a greenhouse can also be made from a canopy which, like any canopy structure, can be expanded over time when your plants need more space. Our greenhouse canopy kits are the perfect garden canopy, with a steel frame and a translucent polyethylene canopy. These greenhouse canopy kits come in one size of twelve by twelve by eight feet and can accommodate plants of many sizes. Each greenhouse canopy has straight six-foot walls and a pitched roof at a 45-degree angle. Doors are on both sides of the greenhouse canopy, with one zipper door and one roll-up door. These garden canopies can be installed in your backyard like any canopy and, like our durable canopy structures, can withstand both high winds and heavy snow.
