If all you need to know, is a simple calculation of your VPD this app is perfect! It has an easy switch to calculate Fahrenheit and Celsius so there’s no need to guess and, it also tells you the best VPD limits for each stage of your plants that actually lines up with everything that I’ve ever seen online
