Picked this guy up cheap on Craig's. Fitted an 8" duct to the front of it and it keeps my 5x5x8 between 77-82 running a 1000 HPS.

I have that one above... too big for your use, but man, it works like a champ.

You definitely want a dual duct. No question. if not, you'll have mj smell blowing out of the hot AC exhaust.
I would probably AC the room the tent is in... not the tent itself. then pull air into your tent from the room and then exhaust outdoors.
if you have an enclosed system, that is a whole different conversation.

Feed the room with fresh outdoor air and you'll have better growth/yields. But, it gets expensive in the summer. depending on where you are at.
I always say I am going to just shut down for the summer, too expenive, but i never do it.

Nice! Looks good...
