The Gro Pro® Elite Black Commercial Grow Bags are constructed from plastic coated mesh, which is heavy duty and durable. The plastic coated mesh provides aeration, enhancing root structure, resulting in a vigorous plant with more fruits and an increased insect and disease resistance. The Commercial Grow Bags are double hemmed to hold its shape when empty. The easy to breath plastic coated mesh prevents circling roots and air-prunes the plant's root structure. Each Commercial Grow Bag is tapered towards the top for easy plant removal. The grow bags are durable, washable and reusable. Resistant to UV light.
