haha please do tell before it gets to 15 pages, my sanity will be gone by then.

"I've run CO2 before, but always have had dedicated aircon units set for about 85F, which dealt with the humidity- or so I thought. Seems high temp alone may have been enough to control the RH... but these ops were 8 and 10kW, impossible in the spaces used without aircon, so I don't have a comparison base."

do you have a thread on this setup you had?
