How long can I keep cannabis seeds stored?

When stored properly, seeds can germinate many years after they were harvested.

They don’t come with a use-by date, but the longer they are stored, the lower the chances of successful germination. Seeds stored improperly may also take longer to germinate, up to a week in some cases.

Basically, the best thing to do is plan your grow around obtaining the seeds. The fresher the seed, the better your chances of a prosperous grow.
