One other possibility is to just leave the whole setup going at night so
that CO2 levels remain constant. If it is CO2 causing the mist, the mist
will continue on during the night as CO2 levels stay constant. If the
misting stops during the night and the early morning, then we can be
pretty sure it's O2.
