Constant inline fan used for lights. How's it affect CO2?

Also all the CO2 I'm pumping out, is it actually getting used by my plants before the other end of the lamp pulls the air in and out? Thanks!

If you set it up so that the light takes air from outside or a different room, it wont be exhausting your CO2.

so would I still be able to run that with a charcoal filter? Or would I need a sepearte inline for that?

Use a separate inline and only have it sucking air through the filter and run a closed loop for the lights, intake from outside and exhaust to the outside.

groovy! thanks man for the insight.
