OVERVIEW ® Rain Bird ET Manager TM The New Standard in Weather-Smart Irrigation. Although over-watering has always been something homeowners, public water agencies, property managers and landscapers tried to avoid, increasing water scarcity has brought this problem into the spotlight. No matter how efficient an irrigation controller’s watering schedule is, however, it must take into account constantly changing weather conditions – specifically evapotranspiration (ET) and rainfall.
OVERVIEW Healthier Landscapes Increased watering schedule control means your irrigation system delivers water only when the landscape needs it. Best horticultural practices recommend deep, less-frequent watering. The ET Manager does just that. Through a process known as “Managed Allowed Depletion,” it allows your soil’s moisture balance to reach a user-set moisture level that increases oxygen and promotes deeper, healthier root systems.
