ET Analysis - 2012
The analysis compares irrigating under ET versus a conventional timer. It support recommendations from the Irrigation Association and leading experts (horticulturists, golf course superintendents, etc.) that watering under ET will save water and is one of the best ways to maintain a healthy landscape.

ET - The Proven Science
At the heart of Climate Controlled Irrigation is the proven science of ET-based irrigation - measuring moisture loss and rainfall to determine the landscapes true watering needs.
Golf courses, municipalities and the agriculture industry have been using ET-based watering for more than 20 years. Now, thanks to technology advancements and investment by ExactET in a reliable, dedicated ET-monitoring weather station network, ET-based irrigation is affordable and easily available for commercial and residential landscape use in Canada.
