Hey guys. I am working on setting up a new grow room. Have been away for a little while but ready again. Like the title says 400 or 600 watt. I am planning on using a 170cfm 4" inline fan with cool tube. A digital ballast that will probably be right outside the room. So i think i can control temps no problem with either. I guess i am just wondering if a 600 watt would be overkill? The width is just under 3.5 feet, but i figure some of that space will be for a fan.
