I was just wondering, I have a 400 watt MMJ grow that I want to start up asap. So far, I have everything except for the tent and will not have one for another few weeks. So I was wondering, since I've heard that white or mylar is the best color/material to use inside of grow rooms, could I use a few of those foam(Correct me if it's the wrong material) tri-fold science boards that kids use in science fairs? Like construct a box with duct holes to run ducting and my inline fan. Have holes on top to run the harnesses for the hid light and hang off of like a closet shelf. Would I somehow harm my plants by doing so? I would love to know your guys' opinions!
