Berry Plastics Black/White Poly Sheeting Commercial Size - 5 mil 40 ft x 100 ft: 20 pack

This is a multi-pack that includes 20 Berry Plastics Black/White Poly Sheeting Commercial Size sheets with a thickness of 5 mil and each measuring 40 ft x 100 ft. The polyethylene film is black on the outside and white on the inside, providing excellent protection for heavyweight applications with puncture, scuff, and scrape resistance. The white surface reflects light back to the plants, while the black surface blocks light from getting to the ground, preventing weed growth and keeping the soil warm. The film is waterproof, light-proof, washable, helps prevent algae and mold growth, and even helps prevent some insects from attacking plants. It is a versatile film that can be used for indoor or outdoor gardening, and doubling it up by putting the black surfaces together partitions off indoor gardens economically and effectively.
