This above ground garden kit snaps together easily with stainless steel posts and zippered corners on the PVC cover. Each small greenhouse works to keep growing areas moist and warm, allowing you to start the season earlier and extend it longer for more crops. The raised beds are made of All Composite Wood Grain Timbers, this vegetable bed is manufactured from 60% recycled, post-consumer plastic and 40% natural fibers that will never rot, splinter or warp. Included with the kit are patented stacking joints for quick and easy assembly and increased strength. The timbers are UV protected, weathering over time naturally and can be sawn just like real wood with a handsaw. The hollow interiors retain heat from the sun to diffuse throughout the night, keeping soil at optimal temperatures for extra growing power. Great drainage on the open bottom!
