How do I edit intervals on Flexible Monthly Schedules?

Editing Flexible Monthly Schedules

Flexible Monthly Schedules recommend a predictable monthly schedule using historical ET data to adjust the watering interval and duration on a monthly basis to follow seasonal change. This creates increasing watering frequency winter to summer and decreasing frequency summer to winter. Currently this schedule mode does not allow you to edit/change the recommended interval. This article will help explain how a simple adjustment to your zone settings will affect the automated frequency recommendation.

In this example, we will use a cool season grass zone based in Denver, Colorado. Here are a couple of months with their watering frequencies.

Notice that April is on an 4 day interval, while June is on a 2 day interval.

If you'd like to adjust your zone to eco-hero mode (water less frequently), or maybe the other direction where you have set it to a lush mode (water more frequently), the only Advanced Zone setting that we recommend changing is your crop coefficient.

How do I change the crop coefficient?

Crop coefficient is the ratio of evapotranspiration (ET) observed for the crop. ET is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. So, each crop has an adjustment factor for ET on how quickly water transpires. To adjust, select the zone you wish to edit via the Zones tab on the Navigation bar, then select the Advanced settings and scroll to the bottom of the screen; now you can adjust the crop coefficient. We recommend you test small (+/-10% increments) and then navigate back to the calendar view to see the actual affect. In this example we started at 80% and moved the crop coefficient dial down to 70% (net -10% adjustment). 

Now look at our new intervals for both months. April is now at an 5 day interval and June is at a day intervaljust by modifying crop coefficient. One simple dial can affect your entire year of watering.
