I am in the PNW and have cool season grass. My back lawn is on constant sun. Today I did a water test to see how much water is getting on the ground and with my rotary sprinkler heads I am just getting 1/4" for 50 min. of operation. I’m currently using the flex daily. Should I just increase the zone time to get more water or is there something else I’m missing that I need to look at?
