Hi all, I'll be doing a setup in one of our spare house rooms (12 x 15) and using 4 (600-1000w) LED lights, and one Veg light in the closet. I'm not sure what to do for cooling and fresh air circulation. I do have a window that slides open and can utilize that in some way. I am thinking a portable AC unit with one of those window adapters that vents out through there. What options do I have?
