Ok, I got it. Thanks dude. I don't know if I told u or not, but my memory is real bad. So if I ask for something you already posted, I apologize. But anyway, your hydro system seems to work very well. And in your tent, u don't run any exhaust, just fans. That's been my only hang up w/the tent. So if I were to get a tent, I might not need an exhaust?
