The Greenhouses for Outdoors by Home-Complete are essential for any home gardener who wishes to extend their growing season. The greenhouse is suitable for both indoor and outdoor use and features a durable powder-coated steel frame as well as a UV-filtering PVC cover for a plant-friendly design, with a zippered door for ventilation and easy access for plant care. The clear PVC cover on the greenhouses features a zippered roll-up door to help protect seedlings from cold weather and frosts, making it easier to start seeds earlier in the season or stretch your growing season later in the year.
