use a inline duct booster fan for a intake. use the mh for veg, hps for flower. put the carbon filter and inline fan inside your grow room where your plants are. run the ducting either out the wall, roof, floor or in another room. i got my cabinet in a closet, i just keep the doors cracked open and the window ac unit on and have the ducting on the wall blowing out the crack of the door. works good. temps are at 70's

with the carbon filter inside the tent or room, it should remove all heat in under 5 minutes if not, you need a bigger one.
