o yea how do you get a four star grow or thread
Just click on "Rate this thread" or "rating" and you get a drop-down box.

I just gave it 5 stars so if you want a 4 star rating, give it a "3" and it'll average out to 4. Nice crop, BTW.

About the window:

How "stealth" does it have to look from outside? Can people see that window from the street, etc? Not sure exactly what you're trying to do. Is that to mount an AC unit or exhaust fan in? Or just to connect a duct to the outside? Is odor gonna be a problem, etc. ?
