I logged on to Hunters run time calculator and got some long run times. I have 4 zones and they are all grass. Live in the Kansas City Missouri area. They suggest I run my rotary head for 24 mins and three times a morning and three days a week. Then the spray heads are suggested to run 7 mins, three times a morning and three days a week. I have a must flat sunny yard with clay loam. Does this seem obsessive?? That's just over 3 hours a day and 9 hours a week. That seems like a lot!
How long does everyone else water?
