long term marijuana seed storage

Humidity is easily one of the biggest threats to your seeds. Here is how different levels of humidity (% relative humidity) affect your cannabis seeds:

Many people forget this, but it’s true—your cannabis seeds are living organisms. Before they germinate, however, they are in a state of rest (much like some animals when they hibernate). And like all living things, seeds can die. When storing your seeds, you’ll want to give them the optimal conditions to ensure they hold through until you’re ready to germinate and plant them.

In a last attempt to germinate your seeds, creating a small cut in the seed’s shell may help. However, this is no miracle cure, and you’ll need to be careful to avoid damaging the inside of your seed.

The ridge is the slightly elevated side of your seed. Like other parts of the shell, this ridge can become extra tough over time. Removing it gently with a sharp Stanley blade can help your seed sprout.

Properly storing your seeds is crucial to ensuring the health and success of your next crop. Keep reading to find out how to properly store cannabis seeds so they last as long as possible.

Not only must you provide ideal environmental conditions for your seeds, you must also maintain them. As such, it is never advisable to open your seed container for any reason other than to plant your seeds. Apart from potentially exposing them to threats such as pests and bacteria, fluctuations in temperature or humidity can also be detrimental to the health and longevity of your seeds in general.

How Long Can Cannabis Seeds Actually Be Stored For?

In theory, there is no hard limit or expiry date on cannabis seeds. When it comes to germination, the fresher the seeds, the greater your chances of success. Ideally, seeds should be planted within a few months of being harvested. However, even seeds that have been sitting around for years can still be successfully germinated. Just remember, the longer a seed has been stored, the lower its germination rate.

Additionally, seeds that have been improperly stored will require longer to germinate. While healthy seeds normally take between 48–72 hours, improperly stored ones may require as long as 5–7 days.

If you are planning on storing your seeds for longer than this, you should consider a refrigerator. Refrigerators are great for keeping your seeds at the low temperatures they require. Moreover, most of the time, fridges are also pretty dark and dry.
