Sure. Just flow enough to get turbulent stirring inside and
even temps. Try to find out as much about the dimensions of the
Warner instruments stage so you can benefit from their
past developments. Search for what they have patented and how
long ago. Avoid using their current patented concepts.

But, you could make a CO2-stat fairly quickly and use a one time measurement
with a CO2 meter lab instrument to calibrate it every so often. The open loop
flow of CO2 is going to have problems of how do you get the humidity
just right as well as the CO2 balance, so it's not a cure all.
