reducing co2 levels

[John Cheeseman]

May I ask why you *want* to reduced the CO2 levels?  The only thing I can
think of is that your experiments call for lower levels than you get by
chance.  In that case, forced ventilation is about the only reasonable
choice that I can see.  Otherwise, if biomass or rapid growth is what you
would want, it seems that having elevated CO2 is desireable.

Just curious
