I just finished seting up my Veg room it is about a 10x10 space. I am Running 2 400w mhl. I also plan in using 2 T12 for my coloning area. But I have yet to deside on what size of fan to use for venalation any sugestion?? My space is in a basement that has very bad issue with lose of heat so I think the smaller size of a fan I use the better off I might be in retaining my heat.
