Create a protected micro climate for plants in your 2' x 4' bed. You can start planting earlier in spring and extend the growing season later into fall for an even bigger and better harvest.The frame installs in minutes. Then add the reinforced polyethylene, vented greenhouse cover to shield plants from harsh weather. When the weather warms up, replace the greenhouse cover with the free micro-mesh insect cover to fend off hungry pests. Both covers have openings on both sides for easy access to plants. Use the six Earth Staples, included, to anchor the frame to the planting mix. Approx. 32" high in back, 24" high in front. Fits our U-Gardens, 2' x 4' Elevated Cedar Raised Bed, 2' x 4' Elevated Cedar Planter Box and other 2' x 4' beds.
