Ok I miscalculated the room can fit about 4 mature plants in there but I'm not going to try all 4 this time. I really need something that will at least only leave that grow room smelling like Cannabis without ducting the air some where else. I need something that can help the smell within the room because there is no way I can duct the air to a different location because basically I don't own this house so I am not allowed to do any type of construction lol. But hey at least I can grow so I'm happy. I just have to find the right odor killer now and get some money for my light . When everything finally takes off I will more than likely be doing a grow log..
