Please help! Venting 4 1000 w lamps 10inch can fan through carbon and back out of the room.

If the intake for your air cooled hoods is not drawn from inside the grow space you will not have any Co2 loss. Make sure your hoods are air tight by lighting a match under the hoods/duct connections and see if the smoke is drawn into the air stream.
