Lawn watering
You want to put about a inch a week as far as runtimes there is a lot of difference depending on the head you have in you yard. If you are south of the turnpike MP rotators are used they have a precipitation rate of 0.4 in/hour which means it will need to run 2.5 hours. 150 minutes divided by the number of days you want to water will give you the run time per day. Spray heads have a a lot higher precipitation rate and will only need to run for 12-15 minutes.
