What is reflective poly?

Optimal grow room lighting is essential in producing high-yield plants. A reflective hood is great start, but to truly increase the efficiency of a lighting setup, growers will implement reflective poly film wall coverings, capturing and directing as much light towards the plant as possible.

Reflective Mylar vs Reflective Poly

Poly film reflects around 90% of light, which is slightly less than mylar but the selling point here is that poly is waterproof and resistant to algae, mould, and mildew. These products are black on the back side, which will prevent unwanted light from entering the grow room, and maintaining privacy.

It is important to keep the films wrinkle and scratch free when applying, as these can lead to hot spots. Using our film accessories and tape will greatly reduce the hassle of setting up your film.
