how long do cannabis seeds stay viable

Before germinating your old seeds, try soaking them in carbonated water enriched with fulvic acid, germination booster, hydrogen peroxide, or gibberellic acid. For best results, use room temperature water and soak your seeds for 12 hours in a dark place.

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

Cannabis seeds have three main enemies:

CAN YOU STORE SEEDS IN THE FREEZER?

Remember, modern fridges are very dry. It’s super important your seeds aren’t directly exposed to these conditions, as the lack of humidity can cause them to use up their nutrient stores just to stay alive.

Ziplock bags, for example, are great because you can remove all the air from them to create an almost vacuum-sealed container for your seeds. Once vacuum-sealed, put your bag inside a dark plastic bag or dark container to protect your seeds from your fridge light.

For short-term storage, a dark cupboard or drawer with stable temperatures is usually fine. Try to keep your seeds out of areas of your house that are susceptible to the natural temperature changes of your local environment.

If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.

With every passing year, or even every passing month, the viability of the weed seeds will decrease.

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.

Germination

First, let’s go over the 4 main factors which can cause cannabis seeds to germinate early, which for the most part are also the same factors which can cause them to take damage, to rot, and to become totally unviable for germination.

If your weed seeds are really pale in color, even white, or they look all shrivelled, chances are that they will not longer germinate.

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.
