As this will keep them away from oxygen, moisture, light, and it will keep them cool too. The freezer is better for long term storage than the fridge. If you do freeze your seeds, make sure to defrost them slowly at room temperature.
What is definitely not recommended is to use a plastic bag, as these don’t do too well when it comes to keeping out light, moisture, and oxygen.
Keeping them cool will also ensure that they are not exposed to too much heat which can damage them. Keep them in a cool place, and some people do use the fridge or freezer, something which we will touch on later today.
Fridge or Freezer
The more time goes on, from the very second the seeds are harvested from the parent plants, the chances of successful germination decreases. Let’s talk about how long you can keep cannabis seeds for, and how to best store them to preserve them for as long as possible.
Another factor which can cause cannabis seeds to germinate prematurely is humidity. You see, weed seeds are fairly dry, and in order to split open, germinate, and start developing the root system, they need a good deal of moisture.
Well, it all does depend on how you store them, as well as the quality of the cannabis seeds and the strain, but generally speaking, 5 years is the maximum amount of time cannabis seeds can be kept without them going bad.
Yes, to keep weed seeds cool, many people will put them in the fridge or freezer, which is fine in terms of cool, and even dark for the most part, as there is no light inside of a fridge or freezer.
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.
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.
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?
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.
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.
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.
