how long weed 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.

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?

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.

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.

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?

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.

Good quality seeds last longer, but how long marijuana seeds last depends on their care and storage.

Some growers even believe that freezing seeds can damage their internal cells.

Glass containers are preferable as they are more resistant to heat and UV ray damage.

This is done to allow for the taproot to sprout before planting but is not a method used by everyone.

Others say that it ends up killing seeds instead of protecting them.

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’.

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.

If you have only kept the seeds for about eighteen months or less, they should be fine to use. After this time, germination may be more complex because older seeds have harder shells, so water used to soak them will take longer to penetrate. You should, therefore, place the seeds in a cup of water with a few milliliters of hydrogen peroxide and leave for 24 hours. This will soften the shell and facilitate the infiltration of the water.

You can definitely successfully germinate cannabis after several years of optimal storage.
