My HPS should arrive in the next few days. I was wondering if it would be ok to use cardboard painted white on the inside to use as the housing for my flowering area? I wouldn't have the light touching the cardboard at all and I would be venting the hot air using a large fan and a length of dryer vent hose. Would this be ok? Any help/suggestions, etc. would be appreciated. Thanx, Farside12 By the way-- I will be posting my pic updates in a few minutes in "Pic pic hooray". All are welcome to check them out!
