What is Crop Coeffient?

Newbie question but what is Crop Coefficient under advanced settings? How do I determine the best setting?

Crop coefficient - Wikipedia and What type of vegetation do I have? should help. Basically it’s a “de-rating” that applies to how much water a crop loses that day.

Thank you second link was very helpful

Find a local agricultural school and they’ll have crop coefficient studies for your area and grass type.

It’s just a measure of how much water your crop/lawn/whatever needs compared to an industry standard. The higher it is, the more water required and the more water applied over time by Rachio (by watering more or less often).

Thank you

This link helped me, it was posted in the Frequency vs Duration thread:

Zone Attribute Run time Frequency
Crop coefficient * Increasing crop coefficient increases the watering frequency
* Decreasing crop coefficient decreases the watering frequency

This is a great page as it breaks down Run Time vs Frequency for each of the advanced zone settings.
