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?
