Growing Degree Unit Calculator

A look ahead.

This Growing Degree Unit (GDU) calculator will allow you a glimpse into the future to see how your crop will progress throughout the year. We use a combination of recorded weather data, a 7-day future forecast, and 30-year historical weather information to highlight the season-to-date as well as a forecast of how the rest of the season will progress. You'll find information specific the the Wyffels Hybrids you are planting to help you plan and improve management of these hybrids throughout the season.
