how long marijuana seeds last

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.

In our article How to germinate weed seeds, we will teach you various germination methods that can make even the Methuselah’s among seeds sprout.

There are a few tips and tricks to apply in order to increase your chances of successful germination.

The fact remains, that seeds exceeding that storage period are significantly harder to germinate.

What is the best place to store your seeds?

So, there you finally have your answer as to how long do marijuana seeds last. Properly storing your seeds takes a little more effort than one would think but I ensure you, that extra care will pay off.

The short answer is several years or up to 5 years, depending on the circumstances.

If you, like yours truly here are suffering from FOMO (for the non-hipsters among us: that’s short for “Fear Of Missing Out” 😉 and subscribed to a plethora of newsletters from various seedbanks to never miss out on a solid bargain, a certain luxury problem could occur: What do you do with all these newly acquired treasures when you don’t have an immediate use for them?

You should bear in mind that humidity and temperature are the two most significant agents to have a quality storage system of marijuana seeds. Indeed, marijuana seeds are susceptible to their surroundings, since they dry out easily in a dry atmosphere and absorb moisture in a humid area. In every 1% reduction in the confined moisture, the life of the cannabis seeds inside the container in also prolonged.
