You can select the new plant mode (settings->zones->select a zone->smart zone) for your zone. The "new plant" method tries to keep the moisture level very high (above 85%). The watering frequency is about every 1.5 day. We suggest watering in the early morning, since that gives the plants time to dry off before nightfall. It's cooler and winds tend to be calmer so water can soak into the soil and be absorbed by the grass roots before it can evaporate.
Please let us know if you have any further questions.
