@daveinmass, good morning! Happy to help recommend a watering schedule for you. Do you happen to know what type of grass seed you have?
I assume this is the total watering time for all of the zones on the watering time? Remember, the Iro doesn't decrease the duration if you change the watering frequency from every 3 days to every day. We'll need to override that manually. Let me know if you need help with this.
It's important to keep the grass seed wet, but do not want to drown it, or worst, have puddling which causes the seed to lift away from the dirt and float away. Do you have anything covering the seed? i.e. light layer of hay/straw, grass clippings, etc?
