2 Faced Poly is waterproof film that is black on one side & white on the other. The white side is very reflective (over 90%) and can be used on the walls and floor of your growing area to reflect light back to plants. The black side provides a light-proof layer. Our poly can also be purchased on easy to use ROLLS with an extra heavy duty 6 mil thickness. The thickest in the industry! Available in 10’ x 10’ sheet or 100’ roll.
