How To Properly Preserve Cannabis Seeds

Marijuana seeds, with their hard outer shell, seem pretty indestructible. Even though nature has bestowed to them defences to a wide variety of conditions, cannabis seeds are not invincible. Rapid changes in humidity and temperature can quickly ruin a container of cannabis seeds. Luckily, learning to preserve your cannabis seeds is quite simple.

YOUR SEEDS ARE A LIVING ORGANISM

Lots of people overlook this, but the truth is—your marijuana seeds are alive. Before they sprout, however, they are in a state of dormancy (much like bears when they hibernate). Just like everything that’s alive seeds can die too. When putting your seeds in storage, you’ll want to give them the perfect environment to ensure they stay viable until you’re ready to grow them.

IDEAL CONDITIONS FOR CANNABIS SEEDS

Stored Cannabis seeds have three nemesis:

  • Light
  • Humidity
  • Temperature changes


Put your seeds in a container and place them in a cool, dry, dark place. Try to keep your Dagga Seeds in their original packaging. At Dagga Seeds, we use packaging to protect our seeds until you’re ready to grow them.

Keep between 20 -35 %

Exposing your seeds to light or sharp changes in temperature may trigger them to use up their stored nutrients before they ever see grow medium. This may mean they won’t have the energy to crack open and grow. High moisture, on the other hand, can cause mould to grow on your cannabis seeds.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

Humidity is probably the biggest threat to your stored seeds. Try to keep the humidity of your stored cannabis seeds between 20 – 35%. Germination can start to occur around 40%+ humidity.

WHERE AND HOW TO STORE YOUR CANNABIS SEEDS

For extra long storage, it’s best to keep your cannabis seeds in a sterile sealed container inside your fridge. If you have another fridge that gets used less than the one in your kitchen, use that fridge to store your seeds.

Whenever possible, keep your Dagga seeds in their original packaging. When you do open a pack of seeds and have leftovers, that you want to store long-term move them into a sealed airtight container.

The zip locks we ship covering the hard plastic Dagga seeds container, for example, are great because you can remove all the air to create an almost vacuum-sealed container for your cannabis seeds. Once the air is removed from the sealed ziplock, put your bag inside a larger container to protect them from damage.

Remember, modern refrigerators are super dry. It’s very important your cannabis seeds aren’t directly in contact with this dry environment. Too low humidity can cause your seeds to use up their stored nutrients just to stay alive.


CAN I STORE MY SEEDS IN THE FREEZER?

Yes, marijuana seeds can be kept in the freezer. The lower the freezer temperature, the slower the seeds decline. However, it’s usually not a requirement to freeze your cannabis seeds. Meet the environmental conditions we listed above, and you should be able to keep your weed seeds for up to five years or more and still get a high rate of germination.

WHICH SEEDS TO GROW NOW AND WHICH TO STORE

When you are ready to grow your seeds, check them and germinate the seeds with damage to the shell first. The outer part of your cannabis seeds is designed to protect the precious genetics inside. If you have seeds with cracks, it’s recommended NOT to try storing them, grow them right away.

At Dagga Seeds, we take pride in our growing and want to ensure every Cannabis Cultivator has the best marijuana genetics in their grow room. We check all of our seeds before shipping them to our customers. If you notice any damage to your Dagga Cannabis seeds, get in touch with our customer service team immediately.
