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.
In terms of seed life, it is said that the shelf life of cannabis seeds is generally doubled in time for every 1% reduction in humidity, making moisture another super important factor to keep in mind here.
This can be hard to accomplish, but any kind of vacuum sealing or airtight container will do fine for this. As you can see, you need to keep your cannabis seeds cool, dry, in a dark spot, and exposed to as little oxygen as possible.
On the other hand, maybe you purchased cannabis seeds, and they are already fairly old when they get to you. Therefore, you might be wondering how long can you keep cannabis seeds?
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.
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.
How Long Do Marijuana Seeds Last Before They Go Bad?
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 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.
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.
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.
This obviously depends on your climate too, as there are places that have incredibly high humidity and others that are quite dry, which can directly impact how you have to store your seeds. As a general rule of thumb, we recommend keeping them in a low-humidity container, and if you live somewhere incredibly humid you might have to use specific methods to decrease humidity.
The seed is undoubtedly just as important as the final result; without quality seeds, you won’t get quality results. Keep in mind that cannabis seeds are practically living beings ready to be brought fully to life. Many new growers don’t know that cannabis seeds require specific care, and the way you store your seeds can significantly affect their outcome.
Once you have your seeds you’re going to want to store them correctly if you plan on using them down the line. In fact, when stored under perfect conditions, you can germinate 5 year old cannabis seeds successfully. Some astonishing cases have been reported of seeds lasting up to 10 years when stored optimally, although the germination times may vary wildly, taking much longer than a fresh seed. For homegrowers, storing and maintaining seeds is quite important, and even more so for seed banks; a badly stored seed may not germinate, and if it does it may not grow properly. There are various parameters you’ll need to follow in order to store seeds long-term.
Seed Storage: Temperature
There are many different factors that come into play when it comes to cannabis seed lifespan, and the most important is conservation. If you’ve obtained your seeds from a seed bank and they come in their own packaging, when it comes to storage you can simply leave them in their packaging in a dark, dry spot; seed banks usually recommend planting within the year.
Humidity is another incredibly important factor that can determine the success rate of your seeds. Relative humidity is essentially what causes seeds to germinate, so they’re quite delicate at this stage and you don’t want them accidentally germinating; keep relative humidity low in their container.
The temperature at which you store your seeds is one of the most important factors. If you’re going for something short-term, you just have to make sure that they’re in an area with a stable temperature – do not store them somewhere where there are going to be temperature changes.
When working from the start you’ll first need to pollinate the flowers on a female cannabis plant and then harvest the seeds once it’s fully matured. Once you have your seeds you’ll need to dry them out before they can be stored or even germinated – they should be ready to harvest once they’ve gone a dark brown color or start showing dark stripes. Most people opt to dry their seeds by simply drying the flowers and harvesting the seeds once they’ve dried out – it makes them much easier to remove from the flowers.
