Default CO2 and scale insects experiment

OK, I guess I don't understand this stuff at all anymore. If 1 atmosphereic
pressure = 101.325kPa, then what does it matter if you introduce CO2 at 7kPa
or 50kPa? What's the kPa of CO2 in ambient air anyway?

It ruined my plans to us CO2 when moving my plants outside this
spring. This site and others give kill time in DAYS, like 7 to 14, for
two spotted mites! Well, back to the drawing board for me. ;-))


Drawing board having things like 1/8" sheets of acetate, welders tank of
CO2, and sufficient ventilation so you don't kill yourself?
