The garage is on a ground floor and gets very little sun. It's not all that hot now but I'm worried the summer is gonna change that. The box will be 2.5 by 4.5 by 6 feet and I won't be using anything hotter than a 600 watt hps. Will the A/C even help without drawing air from outside the room? Do I even need it or will having an intake and outtake fan in there be enough? The garage will open and shut a few times a day so some fresh air comes in. My alternative locations are small and more troublesome. I don't wanna just give up on this. I'm stoked and wanna make this work. Please help.

i haven't been around but better late than never, hopefully.
i used a window-mount a/c rated for a 10'x12' room, 12,000 btu iirc. these a/c units draw air on BOTH SIDES. it will suck air in on the front, cool it, and blow it out the front as it's normal operation.
it will also draw air in from the back and blow it out hot as fuck. this is how it works, it relocates the heat to behind the unit.
my a/c hangs out the wall of my growroom into my garage and on anything above warm days my garage stays hot. i have a window open, a box fan on the rear of the a/c unit, and the rollup door up about 1-2' all the time. i only close it before bed and then i open it in the am.
about here is where i should say i don't really worry as much about keeping shit on the d/l as most around here. i'm in cali, prop 215 compliant, within the laws of my county and (as i've learned since embarking on this journey myself) 3 out of 5 of my neighbors grow outdoor - you can see weed growing in three places from my back doorstep. but window a/c's are loud and obvious. make sure its right for YOUR SITUATION.
these types of a/c units are effective for cooling your growroom but they will pump heat out the back.
