I have mine set at 5", and have for over a month now. My grass is looking green as heck and growing like crazy!
I will say that I am a bit surprised with the watering frequency now that we have warmed up the last week…found it odd that it watered three days in a row last week, and this week is is scheduled for MTTF (I only allow for watering during the week). Before temps warmed up, it was watering once a week, twice max?
Did I forget to adjust something else as the rye took root?
I know we are coming to the end of the season, but it is good knowledge for next year…
