I have the controller 69 pro for my tent, but the a/c has complete control from my app and the same app does my dehumidifier. Anything you can do from the device you can in the app.
I was wondering about that a few years ago. I checked the pH of the distillate, and it was about 4.4. I expected it to be about 7, so I did some web searching and found a page that said it's low because CO2 in the air combines with the water to form carbonic acid, and that lowers the pH. I don't know if that's bad for the plants, but I decided not to use the water just to be on the safe side.
