Our Panda Film is a high quality, extra thick reflective hydro film made specifically for horticultural purposes. It's 100% light proof and is between 220-250 microns making for a solid, long lasting film. It's also UV resistant making it suitable for outdoor gardens as well as indoor grows. By using panda film on your walls, floors and even the roof you can improve light penetration drastically - which in turn promotes better and faster growth and heavier yields.
