Introducing the highest performing reflective sheeting in the Hydroponic industry. ORCA Grow Film® provides the following unique advantages over traditional reflective foils: 99% Diffuse Surface: Microfiber structure creates even light distribution across material surface regardless of incident angle of light. The resulting isotropic surface luminance eliminates hot spots and does not require surface to be hung flat during installation. Highly Reflective Surface: Measured at 94% reflectivity across the full visible light spectrum. ORCA Grow Film® is the highest performing reflective surface in the hydroponic industry. Thermally Reflecting: High infrared reflectance keeps heat where it should be. 100% Light Tight. No Colour Shift or Iridescence: Light reflected from surface maintains the original colour wavelength so you get the full spectrum from your lamps. Durable, puncture and tear resistance: 11 mil thick Waterproof Washable & cleanable with common household cleaners: Mould and algae growth resistant. UV Protected and Stable: Blocks out harmful UV light with wavelength below 400nm, material does not yellow. Recyclable eco-friendly material containing no halogens, plasticizers or VOCs.
