I try to keep humidity lower than most.
I prefer temps in the 70's and humidity in the 40% range.
Hopefully I will be in that range soon just started reading from that site looks like it may slow transpiration coz the dryer the air the more they transpire I know it doesn't say that but just a guess
Just found this
Under Pressure
All gasses in the air exert a certain "pressure." The more water vapor in the air the greater the vapor pressure. What does this mean? Well, in high RH conditions (think of Florida again) there is a greater vapor pressure being exerted on plants than in low RH conditions. From a plant's perspective, high vapor pressure can be thought of as an unseen force in the air pushing on the plants from all directions. This pressure is exerted onto the leaves by the high concentration of water vapor in the air making it harder for the plant to 'push back' by losing water into the air by transpiration. This is why with high RH plants transpire less. Conversely, in environments with low RH, only a small amount of pressure is exerted on the plants' leaves, making it easy for them to lose water into the air.
