Seeds are living things therefore how you store them will affect percentages of germination once you want to grow them.
The best storage conditions are the exact opposite of what makes a seed want to sprout. Seeds will sprout when temperatures go up and exposed to light.
Seeds stored in an container away from sunlight, with a temperature under 50*F with a couple of desiccant packet ( moisture-absorbing gel ) is an excellent method to keeping your precious seeds safe.
Storing seeds in the dark, dry, low even temperature is how to protect your seeds for the highest germination possible.
