How do you best program systems to deal with odd/even ratering restrictions? Every other day is too often for my lawn, I like to put down 1/2" every 3 or 4 days depending on temperature. Every 4 days is OK most of the time, but in the hotter spells, when I would have watered every 3 days, would it be better to run 25% longer every 4 days? Or 25% shorter every 2 days? I am leaning towards running longer every 4 days, I want deep roots and less weeds. Does that sound right? I am in MA with temps getting to the mid 90s during the day and down to 60s to 70s at night, standard seed micture for MA which I think is rye and fescue, some of my Lawn gets up to 8 or 9 hours of sun per day, some is pretty shady and may just get a couple of hours.
