Grow quality plants faster with the Backyard Greenhouse from Miracle-Gro. This portable outdoor greenhouse is a great accessory for anyone from hobbyist gardeners to professional growers. This compact, durable and functional greenhouse unit will extend your growing season by allowing you to start growing seedlings sooner, and protect plants from frost in the cooler months. The translucent fabric 5.5 oz thick cover provides enhanced illumination designed specifically for protection and plant growth. With the innovative Luminate Diffusion Fabric cover, this greenhouse will grow your plants and seedlings taller and faster. Made from a triple-layer ripstop 5.5 oz polyethylene, the translucent cover is waterproof and has been UV-treated inside and out to prevent over-exposure to the sun and burning. It has the ability to retain heat and slow evaporation so you’ll also be able to save water in the process. This durable cover also protects your plants year round. Constructed from a durable 1" high grade steel frame, the greenhouse will provide a backyard growing solution for years to come. The frame features a premium powder coat protective finish that resists chipping, peeling, rust, and corrosion. Bolt together cross rails and bungee cord fasteners lock down the greenhouse cover and square up the frame for a drum tight fit. Screen vents at the front and rear of the greenhouse unit provide maximum airflow, circulation, and temperature control. A 15” auger anchor set is included with your purchase. The greenhouse measures 73.3" D x 73" W x 74" H fully assembled.
