Can Fryd tell me exactly how much to water?

Unfortunately no, we can only give you rough guidance. We don't know your microclimate and many other factors precisely enough, and the amount of water a plant needs can vary a lot from one situation to the next. That's why we want Fryd to help you judge your plant's water needs yourself and recognize whether and how much you should water. Part of that is regularly checking the soil moisture yourself, for example with a finger test.
