Cold Frame Greenhouse Garden Bed: This raised garden bed comes with a cold frame cover to protect flowers, vegetables, and herbs. You can use its wooden greenhouse alone or with the raised bed to spot-fix issues around the garden. Good Ventilation: Control heat and humidity. The openable roof of our cold frame greenhouse vents away old air and allows you easier access to your plants inside. The tilted design of the roof deflects rain to keep water weight off. Polycarbonate Greenhouse: This cold frame greenhouse has insulating twin-wall polycarbonate sheets to protect plants from cold, wind, rain, UV scorching, and wild animals while still letting in 90% of nourishing sunlight. Outdoor Use: The raised garden bed is made of galvanized steel to be lightweight yet spacious and outdoor-ready. The cold frame greenhouse cabinet has a stained solid fir wood frame that helps it hold its shape across an array of weather conditions. Overall Dimensions: 35.5" W x 31.5" D x 36" H.
