The most reflective sheeting on the market! ORCA Grow Film provides a 99% full-spectrum diffuse reflectance with no colour shift or iridescence so the light reflected from its surface maintains the original colour spectrum/wavelength produced from your grow lamps! ORCA Grow Film is made from threads of a high-density reflective plastic which are bonded together to form a unique surface topography. The resulting geometry of the microfibers and the submicron pores within the microfiber create a highly reflective and diffuse surface. Its rough surface allows each individual ray of light to react with a different reflective orientation to spread the light at every concievable angle. Not only does ORCA Grow Film eliminate hot spots, you no longer need to worry about keeping this reflective sheeting absolutely flat or smooth. Sold in 1.37m x 10m.
