For avid vegetable gardeners, winter lasts too long and fall frosts come too early. These new cold frame components let you stretch your growing season and harvest more healthy, home-grown produce. Designed to fit over our 71-1/2" L x 57-1/4" W Cedar Raised Bed (sold separately) with 27 square feet of growing space, the 3-season covers are supported by a sturdy 36-1/2" high enameled steel frame that fits right into the raised bed corners. In spring and fall, use the frame with the insulating greenhouse cover. Made of woven polyethylene, it has a large access door on each side and two roll-up gable vents, all with 2-way zippers. Insect netting covers the doors and vents, and zips open for accessibility. During warm weather, replace the greenhouse cover with the optional woven polypropylene Shade Cover, sold separately. It protects plants from the stress of excess sun and heat and attaches securely to the frame with hook and loop tabs. We also offer the Frame and Shade Cover individually for warm climate gardens.
