Do you think I should drop down to a 4 in duct for the smaller room and keep the 6 in duct for the bigger (For Flowering) or put dampers on. the smaller area is going to be for sprouts, clones, maybe a little veg, and hanging and drying. I have very little air exchange now and my plants look pretty good. I'm sure with the system I'm putting in they'll be great, but I really want to control the odor when it peaks up. Thanks Rhizome
Danyoson Reviewed by Danyoson on . Ventilation Question: Rhizome if your out there... I am looking to redo my growroom now that I've had a couple grows. Rhizome, I read your thread posted a while back, great stuff. My question is can I ventilate two rooms with the same fan by putting in a "T" in my duct work. If I do this I would come out of the fan with an elbow and go into a "T". Drop one line straight down and then continue into the next room with the remaining trunk. If I do this and use an 8 inch fan can I use a reducer and go from an 8 inch duct into (2) 6 inch ducts Rating: 5
