However, if stored correctly, your seeds can last for up to a decade! To last that long, they need to be high-quality and be stored in a refrigerator.

How Long Are Cannabis Seeds Viable?
The bigger the collection, the more options you have to choose from.
The phenotype is influenced by the environment it was grown in and has many effects on its color, smell, and potency.
First, look at the website and the location of the seed bank.
Marijuana seeds should be kept in a cool, dark place such as a basement or in your refrigerator. They should be in an air-tight container and must stay dry. Putting a cotton ball in with the seeds before storage can help suck up any extra moisture (this is why you often see little bits of cotton in seed breeder packs).
Heat and moisture ‘signal’ to cannabis seeds that it’s time to sprout, so as long as you keep the seeds in a dry, dark environment they can remain viable for years. I have heard cases of seeds sprouting after being in storage for 5 or even 10 years. However, you will notice that older seeds take longer to germinate than fresh seeds and a few of them may not sprout at all. As time goes on, fewer and fewer of the seeds will successfully germinate.
