Light Matters, why waste it? The next generation of grow film is here. ORCA Grow Film’s nano structure provides a unique combination of high reflectivity and true diffuse reflection. A reflective combination that is extremely powerful; rendering PET and other grow films obsolete. Not only does it give you more usable light than other reflective films, it is tough and strong. ORCA is available in 10 metre rolls and also in a 22.8 metre seam tape (sold separately). Use the seam tape to ensure a 100% coverage of ORCA Grow Film so no need to worry about gaps.
