do marijuana plants continue to breath co2 during the dark period?

Ya got it, PG. 'zactly.

Plants do continue to transpire- remember also that temperature will decrease when the lights are off, which increases vapor pressure- can lead to condensation/ humidity problems.

You really do need to have good ventilation during the dark period- anything else will eventually go to mold.
