Question on the flex schedule regarding how the watering amount is working and how the lawn handles it.
Right now the zones are set to water when they go below 50%. However, the amount the system calculated to water as a norm is 100% of the inches which equals saturation. However, due to the evapotranspiration (or whatever it is called) by the end of the day it is within the 50-100% range generally.
My question is - if it starts watering in the early morning and the zone is at 30%, then the normal watering would initially make the zone at 130%. Then as the water evaporates and drains throughout the day, it theoretically goes down to some number, say 75% depending on the temp/wind/soil type for the day. So what happens immediately when it gets above saturation, does this water run off? Drain quickly through ground? Evaporate as soon as sun comes up? It would seem that the system would max the water put down in the early morning to 100%. But since the calculation is an entire day mass balance it doesn’t really show you what is going on that first part of the day when the soil is theoretically over-saturated.
