Both the historical and actual ET data is collected from a weather station located at the City of Santa Barbara’s Municipal Golf Course. This station was selected because of its long history of data and its average weather location in the County.
The watering run times (expressed in minutes per electric valve or per station and the number of days of watering per week), which are set by you or your gardener, reflect your particular climate. The Watering % Adjust simply specifies the value at which the percentage adjust feature should be set as climatic conditions change. The change in percentage value will automatically change the run times as the climatic conditions change.
