In the past, I have watered during the night and had it end around 4 AM or so. I have horrible clay soil here in Central Wyoming so that water will sit on top for sure. I have never attempted to water with all cycles ending at sunrise and let the sun do it’s thing. I guess it’s all going to come down to how much standing water is remaining. My telltale sign is mushrooms in the yard. I have been able to use that as an early indicator before more serious issues occur. I do like the idea of ending before sunrise so you get that evap with the sun plus your watering is done before that no water zone during the day. For us, summer heat is mainly between 10-5 PM. The settings I have now is end before 10 AM. I guess that will be my solution if I get too much standing water for the sun to burn off. So for those who have commented. Hard clay soil but plenty of sun. Think I will be ok? Troy, I read that you are in AZ. If I remember correctly, you guys also have hard-impacted soil (clay) in that area as well. You stated you haven’t had any problems.
