The next important factor to keep in mind here is light. Once again, in the wild, bright light signals to plants that it’s time to wake up and grow.
So, if you expose your seeds to light, it will spur on the germination process. At the same time, excessive light, even without germination, can cause damage and cause your cannabis seeds to no longer be viable.
With every passing year, or even every passing month, the viability of the weed seeds will decrease.
Remember that you do want the canister to be airtight to keep oxygen and moisture out, and generally speaking, the smaller the better. You want there to be as little room for oxygen in that canister as possible.
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.
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.
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.
Will Cracked Marijuana Seeds Still Germinate?
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.
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.
