how long can you keep cannabis seeds

However, seeds stored in the fridge will normally last about a decade, while seeds stored at room temperature will have a shorter lifespan.

Germination rates will naturally decline the longer seeds are kept.

When all is said and done, simply put, the fresher the weed seeds are the better. Fresh weed seeds that are harvested from the parent plant are best used within 2 or 3 months, but yes, storage, both short term and long term is an option.

The next important factor to keep in mind here is light. Once again, in the wild, bright light signals to plants that it’s time to wake up and grow.

Remember to store this canister in a cool, dry, and dark place. An opaque canister that does not let light in is needed. If you have a glass mason jar, cover it up with something that will make it opaque.

How To Tell When Cannabis Seeds Are No Longer Viable?

Therefore, when storing your cannabis seeds, put them in an opaque container which does not allow any light in, therefore keeping the seeds away from light. Make sure that this opaque container is stored in a cool place.

If you are going for long term storage, say more than a year, the best method is to vacuum seal the seeds using a vacuum sealer. This will remove all possible air, oxygen, and moisture from the equation.

Well, the easiest way to tell if your cannabis seeds are still viable or not, is by simply trying to germinate them. Now, healthy weed seeds are usually pretty dark, a nice dark shade of green, and they should be fairly round and smooth.

So, if you expose your seeds to light, it will spur on the germination process. At the same time, excessive light, even without germination, can cause damage and cause your cannabis seeds to no longer be viable.
