My house came with an existing Rachio installation for 10 zones. One of the first things I did once I started optimizing water consumption of the system was converting the existing fixed schedule to flex daily. When I created a Flex Daily schedule and saw the total run hours being in double-digits I freaked out and adjusted down the total time by a factor of 2 or 3.
Now that I have a somewhat better grasp on Rachio, I’m starting to wonder about the ramifications of that adjustment. As far as I understand the algorithm now, decreasing the total “daily” run time should simply increase the frequency of watering because the fundamental measure of how much water is needed hasn’t really changed. Is this understanding correct?
If so, that also means that instead of minimizing water use, I’m actually making things worse over the long run by keeping the runs shorter than needed and not letting water propagate to the levels specified by the root depth setting (i.e. keeping water near the surface where it evaporates faster, plus not training the plants to be more drought resistant). Am I on the right train of thought here?
