ORCA Grow Film® is made from threads of a high density specialized reflective plastic which are bonded together creating a unique surface topography. The resulting geometry of the microfibers and the submicron pores within the microfibers create a highly reflective and diffuse surface. The same principle is found in snowflakes, where normally transparent water is transformed into reflective bright white snow through the unique geometry of ice crystal formation. Diffuse reflection is important to hydroponic growers because it eliminates hot spots and creates the even, efficient distribution of light plants desire.

ORCA Grow Film™ is unique when compared to traditional
reflective foils because its surface reflection is both:

A) 99% diffuse reflectance
B) Highest full spectrum reflectance

ORCA Grow FilmTM provides the following unique advantages over traditional reflective foils:

99% Diffuse Surface: Microfiber structure creates even light distribution across material surface regardless of the incident angle of light. The resulting isotropic surface luminance eliminates hot spots and does not require the surface to be hung flat during installation. (Specular vs. Diffuse and Why diffuse reflection matters)
Highly Reflective Surface: 94% reflectivity across the full visible light spectrum, ORCA Grow FilmTM is the highest performing reflective surface in the hydroponic industry. (Performance comparison (See independent 3rd party testing). (What does full visible light spectrum mean and why does it matter?)
Thermally Reflecting: High infrared reflectance keeps heat where it should be.
Light Tight
No Color Shift or Iridescence; Light reflected from the surface maintains the original color wavelength so you get the full spectrum from your lamps.
Durable, puncture, and tear-resistant: 11 mils thick.
Water-resistant. Washable and cleanable with common household cleaners.
Mold and algae growth resistant.
UV Protected and Stable; blocks out harmful UV light with wavelength below 400nm, the material does not yellow.
Recyclable eco-friendly material containing no halogens, plasticizers, or VOCs.
Made in the USA.
