Why is my drip zone not being watered when it drops bellow allowed depletion (50%)? The Moisture level graph seems to think the allowed depletion is set to 100% not 50%.
According to that chart, it has not dropped below depletion yet.
Allowed depletion of 50% is the bottom yellow line.
Your current moisture balance is 0.78", which is 31% of that allowed 50%, which means that overall you are at ~66%.
When your current moisture balance reaches 0 (zero), that means your depletion is at 50%, and it is time to water.
