Alright, so you have purchased cannabis seeds, but don’t want to use them right away. On the other hand, maybe you purchased cannabis seeds, and they are already fairly old when they get to you. Therefore, you might be wondering how long can you keep cannabis seeds?
Well, it all does depend on how you store them, as well as the quality of the cannabis seeds and the strain, but generally speaking, 5 years is the maximum amount of time cannabis seeds can be kept without them going bad.
How long can you store cannabis seeds?
The consensus is that cannabis seeds should last up to a couple of years stored in a cool, dark place — or even up to 5 years if stored really well.

In fact, even with beans much older than that, if they’ve been well stored, apparently it can be worth giving sprouting them a try — cannabis is pretty hardy. But we wouldn’t aim for that!
Generally, the fresher the seeds the better, in terms of maximum chance of germination. Up to a few months is probably ideal.
So, on the one hand, there’s no real ‘use by’ limit for cannabis seeds.
But generally, the longer they’re stored, the lower the germination rate. However, up to a couple of years, the risk of non-germination is still pretty low.
The key: the storage conditions
First, you have won half the battle if you were careful with the original storage. Seeds must be kept in a cool, dry place. Therefore, the best option is to store them in refrigerators at a temperature between 6 and 8 degrees Celsius, and with relative humidity levels between 20% and 30%. And sheltered from light, of course.

For all this you will need an airtight container or canister, or an opaque plastic bottle in which, in addition to the seeds, you should place little pouches of silica gel, to reduce the moisture. With regards to the best place in your refrigerator, the crisper is a good choice, as it is a little warmer than the rest of the fridge. Also, one last tip: if you store several strains in different bottles, it is a good idea to label them, so that you won´t have to open them to see which is which when you decide to plant them.
