You can talk about having a green thumb until you’re blue in the face, but without the right growing environment, your plants might still come up short. Give seeds, seedlings and young plants a fighting chance and an early start in this 27in.W x 19in.D x 63in.H portable, lightweight mini greenhouse. The strong, push-fit, powder-coated tubular steel frame assembles quickly, without the need for power tools. A tough polyethylene cover fits right over the frame, holding in heat and moisture while allowing light to filter through. 4 fixed shelves, spaced 13in. apart, feature an 11-lb. capacity per shelf to handle pots and plants in various sizes. The greenhouse has a roll-up, zippered door to provide easy access.
