Can Cannabis Seeds Go Out of Date?

Yes, cannabis seeds can expire and go out of date. It’s not an easy question to answer, and there are a lot of variables that will factor into how long cannabis seeds last for. If you’ve been sitting on some old cannabis seeds and you’re wondering how long they’ll be good for then this guide will answer all of your questions.

Germinating a seed only takes around two days, so the best way to find out is to try germinating it (check your countries laws as this is illegal in some places). But if that is not an option then we can give you some rough guidelines on how long you can store cannabis seeds along with some top tips to ensure longevity.

Your best option is to learn about how to store cannabis seeds correctly. Physically they’ll last for years, but how effective they will be at germinating and growing into a plant will reduce as they age. Some people claim that cannabis seeds can last years, while others believe that they’re no good after just six months.

how long do cannabis seeds last before they go bad

The difference in how old cannabis seeds can be whilst still working is all about how you have stored them during their life span. If they have been out indirect light then your cannabis seeds will go bad after about 6 months. If you have correctly stored your cannabis seeds in a cool dark place without fluctuating temperatures then your seeds could be good well over one year.

Let’s take a look at how long cannabis seeds last and some of the factors which will influence how long they last, such as storage conditions and how you look after them!

Will cracked seeds still germinate if planted?

If you have cracked seeds, there’s a good chance that they’re not going to germinate. Once the outer shell of the seed has been cracked or broken, the genetic information or material inside the seed is compromised. If you already had the seeds, then it might be worth an experiment to see if they germinate, but if you’re relying on them germinating, it would be best to throw them away and buy cannabis seeds fresh from a shop, such as ours!

Cannabis seeds are quite hardy and can withstand long amounts of time in storage if you take the appropriate steps to protect them. For more information on storing your marijuana seeds check out our guide.
