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 in 2012.
Mike has built a 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 winegrowers learned of this system, many wanted "in". The system now serves about a dozen small vineyards in the Puget Sound AVA, each with their own local weather station (see below).
