hey all i was wondering if anyone new a good way to seperate a 5 by 8 and 9 feet high into light and dark sides{sounds like the force} sure i could hang a sheet down the middle but then i need double fans double intakes and vents wondering how to do this with one set up also they say no light must be dark but if my light in bedroom is shinnig through a crack and hitting the plants because there sure isn't enough power in my 60 watt bulb to effect the plant up close how could it 10 feet away just curious
