Dutch Pimp, and PC are absolutely right. And don't ask for advice if you're not going to accept it.

I may not have a lot of posts on these boards, but if it wasn't for a lot of the people on these boards such as Dutch Pimp, PC, Crispi, Stinky, Weedhound, etc. I wouldn't have a fraction of the information I now have about growing. Don't be such a douche bag.

Anyways, My first grow was in a smaller space and I had very similar problems. First, you don't need a carbon filter on your intake, nor a fan. Both of your fans should be used on the exhaust (not in series either), that should give you more airflow. You also don't really need a carbon filter at all until it gets into flowering, that's when you will notice the smell, not having one will also increase airflow. Your intake should be somewhere at the bottom of the cab. and should be bigger than the exhaust. If you can take some pic's I'd be more than happy to help you out. As long as you learn to stop being a douche and accept advice, of course. :jointsmile:
