| Month | Soil Moisture Depletion (%) | Hours To Operate | Days Between Irrigations | Rainfall Delay
If it rains prior to next irrigation then delay the number of days listed below. Delay is based on rainfall amount equal to the midpoint of each interval (e.g., 0.00-0.24″ = 0.12″; 0.25-0.49″ = 0.37″). |
