Crop Coefficient. I left available water at .12 and efficiency at 70% those seem to be calculated based on the soil and sprinkler head i picked.
How many Zones?
Sorry, i have 8 zones. Previously with my old settings, it was running for 69 minutes total.
I’m thinking you have been watering too often, IMHO. Daily, even at this time of year, is not great for the grass. The top surface should have a chance to dry out, drawing oxygen to the roots, etc. 2-3 times a week sounds better to me
I’m also thinking that, but it been pretty warm in upstate NY this summer. I would assume the flex monthly would have accounted for that.
