I had some new sod put in the front yard. I set up a new schedule so that the particular zone where the sod is now gets watered every day.
I set this zone for 30min on the days when my standard schedule is not running. It ran for the first time this morning but instead of running for just 30min it ran for 60min.
The cycle soak thing is exactly what happened. After reading your article and re-reading the activity log I realized it had watered for 15min, allowed soak for 30min, then watered for 15min more. I’m totally ok with that. I just thought it had been watering for the whole 60min.
