How Long do Marijuana Seeds Last?
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?
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.
Will Cracked Marijuana Seeds Still Germinate?
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.
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 Do Marijuana Seeds Last With Great Care?
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.
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 Long Are Cannabis Seeds Viable?
Good quality seeds last longer, but how long marijuana seeds last depends on their care and storage.
Ideally, seeds should be planted as soon as possible.
Although older seeds do germinate, the amount they do is significantly decreased as time goes by.
Experts recommend planting your seeds in the first three years.
Factors like light, temperature, and humidity will affect your seeds.
If your seeds are exposed to any of these, they will begin to start using their energy stores before they are planted and will eventually not germinate.
High humidity can lead to fungus growing and destroying your seeds.
This is why storage in a cool and dark environment is a must.
How To Tell If Your Cannabis Seeds Are Still Good
You can tell if your seeds are healthy by examining them closely.
Investing in high-quality seeds is the first step to getting a good yield.
Healthy seeds are dark in color and appear to have a waxy coating on the outside when examined under lights.
They feel firm and sturdy to the touch and do not break under slight pressure.
Old or low-quality seeds are weak and will likely crack or crumble easily under small amounts of pressure.
You do not want to waste your time growing these seeds as they will likely crack in storage and never germinate.
Seeds that are too young are lighter in color, like green and white.
These seeds will either take a very long time to germinate or not germinate at all.
A surefire way to check if your seeds are still good is to try and germinate them.
Seeds take around 3 days sprout. If your seeds do not germinate, they’re of no use!
Will Cracked Marijuana Seeds Still Germinate?
No, seeds that crack or get damaged will not grow.
When a seed cracks, its insides are exposed to light and air and thus, it cannot germinate.
Make sure you store your seeds in a way where they do not rattle around or hit each other.
You can also stuff your containers with cotton wool to prevent damage.
One time when people sometimes intentionally crack the outside of a seed is during germination.
This is done to allow for the taproot to sprout before planting but is not a method used by everyone.
How To Make Your Marijuana Seeds Last Longer?
How long marijuana seeds are viable for depends on several factors.
The temperature you store them at must be low.
Higher temperatures can lead to germination and even rotting.
The ideal temperature for storing seeds is 5 degrees Celsius and lower.
Light also signals the seeds to start growing and must be blocked.
Humidity or moisture feeds plants and helps them grow.
This is why your stored seeds should be far away from a humid environment.
Most experts recommend a humidity level below 5%.
Lastly, try to reduce the amount of oxygen the seeds are exposed to as much as possible to avoid the growth of bacteria and parasites.
Use A Reliable Seed Bank
Anyone can build an attractive website and sell seeds, but how do you know that you’re getting high-quality stuff?
First, look at the website and the location of the seed bank.
If it is an offline retailer, check out the address of the shop and make sure its legitimate and not just some P.O box.
You can also check the reviews online.
If it is an online business, look at the website and its reviews.
Sites that have several positive reviews can be trusted.
Next, look at the shipping details of the company.
How long will your seeds take to reach your mailbox? Do they offer discreet packaging?
Make sure that they offer a delivery guarantee.
This means that if your product is seized or damaged along the way, you will be guaranteed a replacement.
This is often the mark of a trustworthy and confident seller.
Look at the variety of seeds the store offers.
The bigger the collection, the more options you have to choose from.
Finally, a company should have a high success rate.
If they have great reviews and offer replacements, free shipping, and great customer service, you can confidently take a chance on them.
Select Strains With Strong Genetics
Good genes create good plants.
Just like in human beings, characteristics of parent plants are passed down into their offspring.
Each strain carries its unique genotype and phenotype.
The genotype is the genetic makeup or blueprint of the plant.
The phenotype is influenced by the environment it was grown in and has many effects on its color, smell, and potency.
Breeders work hard to isolate specific strains over generations of plants.
You can differentiate between strains with strong genetic backgrounds based on effect, taste, look, and smell.
Some strains also have their unique qualities due to being grown in different areas of the world over centuries.
There are thousands of strains available, with each having slightly different characteristics due to hybridization.
Do your research and make sure your seller has a good reputation.
You can find this out by reading on their website and seeing if they provide information on their breeding procedures and plants.
Store Them Properly
The type of container you store it in will affect how long your seeds will last.
Improperly stored seeds will lose their ability to germinate quickly.
It is advisable to always add a desiccant like silica gel packs or rice to remove humidity.
It also absorbs excess ethylene that is produced during the aging process and prolongs the life of your seeds.
The most popular methods for seed storage are-
A Ziplock bag works well when you want to store seeds for a short duration of around 5-6 months.
Any longer than that and your seeds may start to go bad.
Put your seeds into your bag, try to remove as much air as possible and then seal it tightly.
Then keep your bag in a cool and dark place.
Vacuum- Sealed Bag
A step further than a regular Ziplock bag, a vacuum-sealed bag will ensure that there is no air left inside your bag.
This will allow you to store your seeds for a longer period.
You will still need to ensure to keep it in a cool, dark environment.
Some seed banks deliver seeds in a vacuum-sealed package that can store them until they’re ready for planting.
Another great method for long term storage is keeping your seeds in an airtight container.
Glass containers are preferable as they are more resistant to heat and UV ray damage.
Just make sure to keep them away from light.
If you are looking to store your seeds for over a year, you can refrigerate them.
Refrigerators offer constant low temperatures and dark and moisture-free environment.
Keep your seeds at the back of your fridge so that they are away from any potential moisture or temperature changes from opening it often.
Make sure the container or bag your seeds are in is airtight and heatproof.
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.
Freezing marijuana seeds is a debated method.
Freezing is used by some to store their seeds for years on end.
Others say that it ends up killing seeds instead of protecting them.
Some growers even believe that freezing seeds can damage their internal cells.
Using special laboratories and equipment can allow for the careful freezing of seeds, but this is not a very cheap or accessible option for many.
