The only problem is if you are on a well like me. My well only produces 6 gpm so in order to water my 14 zones it takes me over 9 hours a day if all zones were to run 45 minutes each. My PR is roughly .31 inches per hour so there is no way to get the 1/2 inch twice a week. So I am forced to start watering at sunset most nights. I will get red thread but not much else.
