I tried out the ‘finish by sunrise’ feature this season and my grass watered last week at ~12:30am because my 2 other drips needed to run afterwards also. Not sure how I feel about the grass watering at that time, I may adjust this feature.
I’ve always had my grass to run on the hour marker (i.e. 5:00 am) with drips scheduled to run 1 minute later to give priority to grass. Maybe I’ll flip flop them now so that the grass is the last thing to run on any given day, so that way they will still finish by sun rise but it’ll be the last thing to run.
