Yeah, got a 6 in max fan that'll be pullin through a can33? I think it's a can33.. As far as exhausting, I have a couple of options. Lazy option is to just exhaust it into the main area of the basement.... Second option is there is this duct in the closet of the grow room that literally just goes straight up to an open vent in the floor above it..could just blow the air up and out of there. Third and probably smartest option is to run ducting ALL the way across the basement to the laundry room - there is a window that opens but is covered by my backyard porch, so isn't visible from outside. Dirty as fuck under there, but acsess to the outside I guess. So yeah, not exactly sure how I'm gunna run that yet, but should be able to figure it out...in theory...hopefully lol
