@torpster, thanks for reaching out. We do not recommend using Flex Schedules on new lawns (sod or seed) – sorry for any confusion. A Fixed schedule using IFTTT to automate hourly schedule runs would be your best solution. Here’s another community post that details how to setup the IFTTT with your Iro.
I’d highly recommend reverting to the default settings for root zone depth and allowed depletion. 0.5 inches (even 1 inch) is a VERY swallow root zone depth. Also, setting your allowed depletion to 90% is the opposite of what you want to do for sensitive, shallow rooted plants. Depending on your plant types, Allowed Depletion should look like this:
- For most landscape purposes, 50% AD represents a reasonable overall value for the typical soils and plants used in landscapes in which you irrigate when the soil moisture level is half depleted.
- For sensitive, shallow rooted plants (where little reserve water is available), or very heavy compacted soils, a smaller depletion should be considered (i.e. 30-50%)
- For stress-tolerant plants, such as desert plants, deep root zones, or lighter soils, a larger depletion can be used (i.e. 50-70%)
Hope this helps
