I use Panda plastic, black on one side, white on the other ... and throw in a little Mylar for extra reflectivity at the lower levels. Plastic cleans easily and resists mold and mildew. Seems to be working okay.
OR Freebird Reviewed by OR Freebird on . Reflective walls A mate of mine assures me that brilliant white emultion paint is just as effective as foil for reflecting light. I've tryed both in my room. I'm using white at present and this has had no negative effects on yeild or quality. It's much easier and cheaper to paint walls white, rather than pissing about with foil. Rating: 5
