how long will weed seeds stay good

There is no denying that the right storage is important, and you can read more about how to correctly store marijuana seeds in our useful blog here. If seeds are stored in direct sunlight or damp, humid conditions, it is unlikely that they will germinate if they are over a year old. Seeds that are cracked or crushed will also fail to sprout into seedlings, so it is vital to keep unused seeds in a safe container. Those little sachets of silicon balls that you find in new bags are very useful at absorbing any moisture that could lead to damp and mold.

How to store weed seeds?

Why is it important to know the age of cannabis seeds?

No, although there is a considerable variation in the appearance and color of cannabis seeds, the outward appearance gives little indication to the health and viability of the strain. As long as the seed’s outer casing is smooth and intact, the inner genetic material will be protected.

Make sure that the water is lukewarm – about 22° C and ensure that the glass is kept away from light sources. Keep a close eye on the seeds during this time, as if they start to open, you will need to take them out quickly, or they will ‘drown’.

Older seeds are less predictable than younger seeds. The older the seed, the lower the chance that it will successfully germinate. Even if they have been carefully stored according to all the expert advice, the time it takes for them to germinate varies hugely. If you are planning to cross your own plants and develop your own strains, it is essential to get organized and to record the age and variety of your weed seeds to avoid wasting time in the future.

Marijuana seeds should be kept in a cool, dark place such as a basement or in your refrigerator. They should be in an air-tight container and must stay dry. Putting a cotton ball in with the seeds before storage can help suck up any extra moisture (this is why you often see little bits of cotton in seed breeder packs).

Heat and moisture ‘signal’ to cannabis seeds that it’s time to sprout, so as long as you keep the seeds in a dry, dark environment they can remain viable for years. I have heard cases of seeds sprouting after being in storage for 5 or even 10 years. However, you will notice that older seeds take longer to germinate than fresh seeds and a few of them may not sprout at all. As time goes on, fewer and fewer of the seeds will successfully germinate.
