I am building my first small growroom and I have a question???

I was wondering if I could use flat white painted pegboard with mylar behind it for the walls? I have the pegboard and a roll of mylar backed paper. Was just wondering if the holes in the board would mess with the light refraction,hard to explain. Probably a dumb question just wanted some opinions. Would it be better to just tack the mylar to the face of the pegboard with 3M spray adhesive? Thanks.......

no, it would be fine, or at least i can't see anything wrong with it.. just make sure the mylar is pulled tight. Chuck up some pictures! Good Luck!

Right on,I will give it a shot then. Thanks for your quick response Ballard...
