window ac help needed

How would I mount a window a/c?
Should This be mounted on plywood?
I have my window box there now,or is there another way to mount?
Will odor from room go through ac unit and stink up the neighborhood?

Not sure what you mean man. Are you mounting it in an actual window or just outside the grow room but still inside a bigger room.

I could mount in either,is there a particular advantage to puttin it in a wall/door vs window?
Its just seems like the if i mount inthe window hot air with a skunky flavor will our out as i cant filter that air....

ac units r not suppose to bring air in nor out.

Here is a good picture to show you how a/c's actually work:

thanks for the pic!
ok looks like a window ac will work
