TWO TIERS - This greenhouse features two tiers of shelving. This allows you to start multiple flats of seedlings, store potted plants in winter months and care for seedlings until they’re ready to plant in the ground.ZIPPED PVC COVER - The outer cover of this greenhouse is made of PVC to trap heat, and to protect delicate plants from bad weather, and insects. The door zips open and closed, and it can be tied out of the way with the included straps for easy access to your plants.UNOBTRUSIVE - This vegetable and flower greenhouse measures just 20 inches wide and 31.5 inches high, giving it a small footprint. This makes it great for maximizing the growing space on your deck, patio, or balcony.DURABLE FRAME - This outdoor greenhouse is made of durable steel tubing that is built to stand up to the weight of potted plants and features powder coat paint. This protects the frame from rust and corrosion from exposure to the elements.DIMENSIONS - L50 x D45 x H80cm
