I've just check my max temps is 80 F... I guess this is not too bad and as didn't saw any sign of heat stress, I wasn't really too concern.

I'm using an 450 CFM fan and the room is 12" x 8" x 7" high = 672 cubic foot area.
450 CFM / half = 225 CFM (let's say scrubbing and the 25" duct cut it by half)
672 / 225 = 2.986666 about 3 minutes to exhaust the whole room.
I still exhaust the room in LESS than 5 min.

Here is today's update as the same time.
Those are some gorgeous ladies you got there.. I hope mine come out looking as good (probably not since mine are mostly mutants.. lol.. Teenage mutant ninja Ganja!!)
