AC and odor

I don't grow at all in summer because of heat. This time of year, when we have some warm days, my last few weeks to go crop is getting too warm, even with all the fans on full. I can add some AC to the room the closet is in and fix it, but then the AC vents to the outside.

The question is, will that air have an odor? If so is there a way to add some ONA or something to mask the air that is being blown out?

you need to scrub the air coming out of the AC unit, yes it will have a odorthis is a option. it will hook up to all 4in and most ac units
are 4 to 5 in ducting. this is the stealth air box 2
