I have just setup my rachio system. Loving it so far! What a breeze it was to setup! Configured for 9 zones here in southwest Florida. Initially, I have configured all sprays to run for 12 minutes and all rotors to run for 20 minutes. When the zones ran for the first time, all sprays ran for 6 minutes and the rotors ran for 10 minutes? Any idea why? Is it because of the type of soil for each zone I chose? Thank you in advance!
