Marijuana seeds can be preserved for a minimum of 3 years without any loss in germinating power. Probably even for much longer, only time will tell.
It’s obvious weed seeds germinating power decreases as the years progress. Therefore you should allways store some additional seeds. Will seeds still germinate after 100 years have progressed? No one knows.
Storing cannabis seeds in the freezer is the right choice if you want to store the seeds for decades or longer. Can this do any harm? No, in nature, seeds freeze all the time, after that spring begins and germination starts. Make sure the weed seeds are totally dry before freezing.
Storing marijuana seeds in airtight pots.
The germ that hides behind the tough seed outer shell can survive for years feeding on food reserves it inherited from the mother plant. Food supplies consisting of fad starch and sugar keep the germ alive as long as these reserves are available. Maximum lifespan is around 6 years but seeds that survive for a longer period of time are no exception.
So, now that you know the enemies, you need to learn how to defend yourself and keep your weed fresh. Thankfully, it’s a fairly simple process, and you may already have everything you need to start storing your weed for a long period of time.
Lost THC won’t be the only consequence of keeping your weed in a warm spot. As it gets weaker, it’ll also taste and feel harsher upon smoking. This, of course, is a result of the terpenes drying out over time. Excessive light and moisture will bring about their downfall as well.
Keeping cannabis fresh is simple when you’re armed with the right knowledge.
If you’re more inclined to smoke CBD-rich strains, you may wonder whether any of this applies to you. Well, since CBD is also a cannabinoid, and since the buds also have terpenes, it too can degrade with age. The high isn’t a factor, but you’ll miss out on the other potential benefits of CBD.
Before we go deeper into that discussion, though, we want to offer you a deeper understanding of what happens when your weed starts to age.
You have to maintain a very precise balance when it comes to humidity and cannabis. If your storage method introduces too much moisture, you run the risk of mould infestation. If it isn’t humid enough, though, the terpenes and cannabinoids will end up withering away. While they’re quite different outcomes, the unpleasantness is equal between them.
