Have a successful growing season with help from this portable walk-in greenhouse! With four shelves for growing plants and storing supplies, this small greenhouse for outdoors is perfect for creating the ideal growing climate for all your favorite vegetables, herbs, fruits, and flowers. This greenhouse is durably constructed from an iron tube frame with a steel wire shelf and a polyethylene covering coated with a Uv ray protective finish. The cover of this walk-in greenhouse protects plants from inclement weather, like frost, excessive heat, and too much moisture. The cover is transparent so light can filter through to ensure plants receive the perfect amount of sunlight needed to grow. A roll-up door with zippers allows you to control air flow in and out of the greenhouse and easy access to plants. Simply tie the door up to keep it open or untie and zip the sides down to keep it closed.
