When running co2 or not humidity is real important for it all to work right. The Stomata are what eat the co2 and produce the photosynthesis, they open and close depending on humidity. So if your low 30% 40% your not getting the max from your set up. Got to keep it in the 60 to 70% range for max uptake of co2. Were talking about Vapor Pressure Deficit.
