I hope you can view this as a simple misunderstaning... Obviously there was some misinformation on both yours and my parts-- I just wish you'd stop saying im trashing your thread... understand that this was not my objective.

Now, as to your post...

" I think I might have solved my temp problem with this fan because the air outside is cold and if the fan draws the outside air, it means that my grow room is going to be cool too, hurray."

Just out of curiosity, what part of the country do you live in? Hopefully you're getting good clean country air... what are the average day temps for your area? Remember, temps can plumit at night so be sure to have your light cycle set up so they get their dark period during the day.

Again, I hope we can put that misunderstanding behind us
