16m
In this episode of the Agronomy Answers podcast, Zach Hefty sits down with Heidi Arneson, a Registered Seed Technologist who runs the Hefty Seed testing lab, to break down the difference between warm and cold germination scores. They cover why the warm germ on your seed tag reflects ideal 77-degree conditions, why Hefty runs its cold test at 40 degrees instead of the industry-standard 50, and what a variety needs to score to earn the 40 Series label. If you’ve ever wondered what’s really behind the numbers on a seed tag, or why cold germ scores matter so much for early planting in the North, this episode is packed with practical insights.
