I hear storing in a cold environment. Such as a refrigerator is wise. I think years of storage life are expected.

I heard Bill Gates has a personal seed storage underground vault you can drive 18 wheelers into. Iceland? Somewhere like that. Very cold with a constant underground temperature.

The key is getting original unmodified heirloom seeds. (Getting harder and harder to find.. the government and people like Bill Gates are genetically modifying seeds to harm the public.. Just good enough to seem okay, but long term side effects to terminate you.) 🌱
