Have a successful growing season with help from this small greenhouse for plants. With three shelves for growing plants and storing supplies, this portable mini greenhouse is great for creating just the right climate for growing vegetables, herbs, fruits, and flowers. This greenhouse is durably constructed from an iron tube frame with steel wire shelves and a polyethylene covering coated with a Uv ray protective finish. The durable cover protects plants from inclement weather, like frost and excessive heat or too much moisture. The cover of this mini greenhouse is transparent so light can filter through to ensure plants receive the right amount of sunlight needed to grow. A roll-up door makes accessing plants easy and allows for controlled airflow in and out of the greenhouse. Simply tie the door up to keep it open or untie and zip the sides down to keep it closed.
