For the Stomata to stay open and also maintain transpiration at prime levels for maximum plant growth the hum/temp difference between night and day levels require a consistent number. Difference 0-10F and 0-10%RH is within range, to maintain those numbers at as close to zero as possible a controller is needed to operate as needed intake/exhaust, CO2, and heat. In search for the best device to maintain proper day/night hum/temp numbers. Any advice???
