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.
The answer to the question ‘how long do marijuana seeds last?’ is one that is hotly contested by many growers. Some claim that, if stored correctly, it is possible to grow cannabis from seeds that are over a decade old. Others argue that marijuana seeds are no longer viable after a couple of years. Most seed banks advised growing seeds within a year of purchase. So who is right? As many growers find they have a few old seeds lying around or newbies may have been given some spare seeds by friends of the family and are interested in growing weed for the first time, it is a question that is worth answering.
Why is it important to know the age of cannabis seeds?
That said, very elderly cannabis seeds sometimes feel weaker when one gently squeezes them. Throw them away if the husks split open and release the dusty contents – these are seeds that are obviously no good. The best way to store marijuana seeds is in a dry, completely dark container in a cool place such as a refrigerator or somewhere with a constant low temperature. You can definitely successfully germinate cannabis after several years of optimal storage.
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.
The life of a cannabis plant begins in the germination stage. It finally starts to sprout after a period of being dormant. Even a seed that is a few yea. Read more
Mother Nature’s designed them to respond to their environment within particular heat and moisture to signal the seed when it’s time to germinate.
The short answer is several years or up to 5 years, depending on the circumstances.
Key factors for your storage conditions environment
You should bear in mind that humidity and temperature are the two most significant agents to have a quality storage system of marijuana seeds. Indeed, marijuana seeds are susceptible to their surroundings, since they dry out easily in a dry atmosphere and absorb moisture in a humid area. In every 1% reduction in the confined moisture, the life of the cannabis seeds inside the container in also prolonged.
Even if you’re organized, methodical, and careful about storing seeds, older seeds could be more difficult to germinate, resulting in more fragile plants, a thinner stem, and require more care and attention as seedlings.
The most important factors when storing your seeds are keeping them cool, dark, and dry. Maintaining a constant environment with little or no fluctuation is vital to ensure the stability of your stored seeds.
