In 2012, with a financial contribution from his friend Andrew MacMillen of Hawkfeather Web Design, Mike purchased a weather station from Davis Instruments and installed it in his vineyard.
Mike has built a web-based system around this data, that facilitates weather condition warnings via txt or email, and tracks/plots Growing Degree Days, etc. Most significantly, it extrapolates Powdery Mildew growth from weather conditions and warns the owner that it's time to spray.
Once other local growers learned of this system, many wanted "in". The system now serves a handful of small vineyards in the Puget Sound AVA, each with their own local weather station. The project is available at no cost, more info at the project home page.
