The cool tube is a great addition to any small confined area. You can get away with using the little fans. I just pull cool air from one side of the grow room and it goes thru the cool tube and then vents out the other side. I love it. I am going to do some improvements on it in the next few weeks so i can take it apart easier so i can clean it when it needs it. I don't want to use tape all the time on it because it gets to be a pain to take apart when need be. I will get this room to near perfect status as soon as i can. This hobby never ends. And i like it. LOL
