whaz up everybody.... Yo I got a 4x5x8 room all set up for buddy a rhino and a Misty bitch... My question is> If I leave a 8 x 16 inch space at the top of the door to let the humidity out.. Will I loose a ton of co2 up there... I have to moving fans in there just of the top of the canopy. Also if i want to clean my floor should I worry about the fumes from the cleaners on around my plants? i.e clorox mildew cleaner, widex etc? Lights up dd
