Have a successful growing season this year with help from this portable walk-in greenhouse! With four shelves for growing plants and storing supplies, this small greenhouse for outdoors is great for creating the right growing climate for vegetables, herbs, fruits, and flowers. This greenhouse is durably constructed with an iron tube frame and a Pvc covering that is coated with a Uv ray protective finish. The cover protects plants from inclement weather like frost, excessive heat, and moisture. The cover is transparent so light can filter through to ensure plants receive the right amount of sunlight. This greenhouse features four shelves that are made from steel wire to hold planters and keep supplies close at hand. Store the heaviest planters on the bottom shelf. A roll-up door with zippers allows for controlled airflow in and out of the greenhouse and easy access to plants.
