Damn you! ;) Now this is bothering me. However, I am thinking that it
shouldn't matter because we will be faced with the same thing in both
runs of the experiment. The effect should occur the same in each run and
so the results should be OK. Luckily CO2 concentration doesn't affect O2
or N2 or else then we'd have a difficult problem.
All I have to do is run the setup for an hour or two before beginning to
make sure the temperature and gas concentrations are equalized before
beginning. Does that seem reasonable?
