Carbon filter + CO2

[stewbacca6]

Is there any way to use CO2 effectively while filtering the air in your grow room?

Also, I have a Vortex 6'' 449 cfm fan, what kind of filter cfm rating should i get? thanks

Yes, If you're not looking to buy 2 fans you can do this...

Strap your filter to the roof of the room or go with an in-line filter. Just make sure the intake is as high as it can be. CO2 stays low in the air and that's why you use a smaller fan to help lift it up off the floor.
