Hi @JeremyW, good afternoon. Thanks for reaching out!
In theory, yes – however, the duration you see in the app might report the cycling time for Smart Cycle if you have the feature enabled. The nozzle rate (aka precipitation rate) is one of a few factors used to determine your zone durations – other include the vegetation type, exposure (sun/shade), and the zone’s advanced settings.
Please note, the existing watering times are not dynamic and will need to be deleted and recreated for the new nozzle settings to utilized for the recommended schedules.
Yes, it does! If you can run a zone for a set duration, then find the average flow rate in GPH or GPM, please let us know and we can calculate the precip rate for the custom nozzle very easily.
Hope this helps.
