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.
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.
Why is it important to know the age of cannabis seeds?
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.
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.
Once you have received your ordered cannabis seeds, most growers start their grow right away. After all, your seeds are fresh, and you want to prevent t. Read more
Cannabis seeds can withstand long amounts of time in storage, as long as they are well protected. A cool, dark environment with no humidity or strong aromas is good to store the seeds for a few months, but if you want to extend the shelf-life of the seeds, then they must be refrigerated.
How long your seeds will last can vary. If great care is taken for the seeds to be protected from humidity and light, and provided a cool environment the center of the seed will remain dormant, making the marijuana seed last longer. That way, the only thing needed to germinate the seed will be to soak them overnight in water then place them in a damp tissue or Jiffy plug and germinate normally.
There is plenty of debate surrounding how long do marijuana seeds last before they go bad. Some people say that they can last for years if they are kept in the correct conditions, while others disagree and state that they can only be used within 6 months to 1 year after packing. So the question is, how long do marijuana seeds last?
How Long Do Marijuana Seeds Last Before They Go Bad?
Unfortunately, the answer to will a cracked seed still germinate is No. It cannot germinate as the valuable internal part of the seed that contains the genetic information of the plant is exposed, then the seed will no longer germinate. Great care must be taken to ensure the seeds are not damaged or crushed, including putting them in vials stuffed with cotton wool to ensure they don’t rattle around and harm each other.
As we mentioned before, marijuana seeds can be made to last very long if they are refrigerated. Without any interference, marijuana seeds can last a few months before they go bad, even up to a year if they are kept in a cool, dry and dark place, but if they are refrigerated, marijuana seeds can last up to a decade.
In some cases the latter may be true, if they are weak genetics or the seeds have been kept in adverse conditions. How long the seeds will last depends totally on the conditions they are stored in. If the seeds are humid or exposed to light, they will not germinate from being damaged internally. It is also essential to add that the seeds must be protected from being crushed.
So, how long marijuana seeds will last depends on the care you take to conserve your marijuana seeds in the correct way. If you are very careful marijuana seeds last you for ages. You can even stock up on strains to have your own collection and at the same time, remain self-sufficient throughout the year.
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.
