I am a little confused about the ratings listed for carbon filters on websites. My CAN filter has something called a "Maximum Exhaust CFM" which is 200cfm, and something called a "Max Recirculating/Scrubbing CFM" which is 400cfm. I have a 6" Inline Fan hooked up to a speed controller that's rated at 400cfm. I want to be clear on what these terms mean before going into flowering.
I am using a passive air intake system btw (inline fan sucking air out of a 4x4x8 room)
