Ive been messing around with how I want to install my carbon filter to my exhaust in my growbox. Im using a 6" 250cfm inline fan. I was going to sandwich some carbon between 2 AC filter layers, but one layer of the filter alone blocked enough airflow to get my box to 95 degrees. Would putting the filter before the fan, so that the fan sucks through it, be more effective in my situation? I'm mostly worried about my temperature, which Ive had alot of trouble controlling.
