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.
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.
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?
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.
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.
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.
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.
How to germinate weed seeds properly?
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
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.
How to rescue old seeds?
Another useful trick to encourage the germination of old seeds is to scrape off the seed’s outer layer with sandpaper. This creates micro-abrasions that similarly allows water to permeate. Here’s a good technique as you don’t want to overdo it. Get a piece of the finest grain sandpaper and roll it up into a small tube with the rough surface on the inside and stick it together with some tape. Pop the seeds inside and use your hands to cover the ends. All you have to do is gently shake for a few minutes.
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’.
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.
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.
Experts recommend planting your seeds in the first three years.
However, if stored correctly, your seeds can last for up to a decade! To last that long, they need to be high-quality and be stored in a refrigerator.
How To Tell If Your Cannabis Seeds Are Still Good
Now that we have covered everything there is to know about how long marijuana seeds last and how to store them, you are all ready to begin your growing adventure.
Just like in human beings, characteristics of parent plants are passed down into their offspring.
You will also want to make sure that your fridge is “no-frost” or has a no-frost area to shield seeds from frost damage.
