New seed

Troy’s method above is the simplest.

But if you want to do it with only one schedule, I suggest this:

Daytime Watering Only?

I think you could do this by setting up a fixed schedule with manual cycle and soak. For example, you would set it to start at 6am in the morning. The cycle could be 10 minutes and the soak would be 50 minutes. And you want it to end after 10 hours. Then when the duration for the zone pops up, set the duration for 10 times 10 minutes, or 100 minutes (which you’ll have to put in as an hour and 40 minutes). That should work and you can play with your timing. Just make sure that you pick a nozzle …

I think there is a limit to the number of schedules you can have, so Linn’s method may be necessary if you have maxed out the number of schedules. It may be a bit complicated to understand, but once you have it setup, you’re good to go from now on.

Unlike most, I don’t put down mulch on top of the seed. Therefore I have to water more frequently (but shorter duration) to keep the seed moist until it germinates. So my schedule waters every hour for two minutes. It starts at 6 am and ends at 7 pm. The end time is determined by the start time plus the total duration, taking into consideration the number of zones you have.
