Store them incorrectly, however, and you run the risk of spoiling your entire growing season. Seeds can die, be damaged, or simply lose their efficacy if stored poorly.
All great cannabis plants begin with quality seeds. Unfortunately, many growers overlook the simple fact that seeds are living organisms that need preserving to remain in tip-top condition. Store your seeds in haphazard ways, and you run the risk of affecting both quality and germination. Luckily, proper storage is easy to do as long as you know how.

Seeds need to be stored in cold but not freezing conditions. The ideal temperatures are around 6 to 8C. These lower temperatures prevent the seeds from germinating and slows their vitality, allowing them to remain useful for much longer. That’s why longer-term storage is recommended in fridges where temperatures can be set and controlled. Whatever environment you are using, it’s important that temperatures don’t fluctuate, as this can ruin seeds. Avoid moving your seeds from location to location, and never leave them baking in the sun or near a radiator.
Lastly, place your container in a cool, dry environment for storage in the short to medium term. Ideal places include dark cupboards and drawers. Choose an area that isn’t affected by day-to-day changes in temperature. More longer-term operations will need to be stored in the fridge. In this case, remember to cover whatever container you are using in opaque material so that it’s shielded from light. Ideally, a second or less-used fridge is best.
If you’ve sown your seeds and still have some left over, this guide will ensure that those extras never go to waste. With these top tips, you’ll never run afoul of the seed storing gods and can enjoy your favorite seeds in the many months to come.
If there is as low as 8% humidity in the container it can cause fungi to appear inside and outside your seeds, at 40-60% your seeds will sprout and beyond that, they can drown in less than a day.
If you’re storing seeds for a couple of weeks it’s okay if you leave them in the original package as long as they are in a dark, dry, and cool place.
If you’ve ever germinated cannabis seeds before, then you know that light is an important factor when it comes to the probability of the seed germinating or not. If your seeds are exposed to light for too long they may end up germinating before you’re ready to plant them.
This obviously depends on your climate as there are places that have incredibly high humidity and others that are quite dry, which can directly impact how you have to store your seeds.
There are various parameters you’ll need to follow in order to store seeds long-term.
Tip: When storing seeds in the fridge or freezer you can add silica gel sachets to ensure they’re completely dry.
When storing seed you want to provide optimal conditions to ensure they are still good until you’re ready to sprout them.
Ideally, you want to store your seeds in a cool, dark, and dry place. Whenever possible, keep your seeds in their original packaging. At Royal Queen Seeds, we’ve specially designed our packaging to protect our seeds until you’re ready to plant them.
In a last attempt to germinate your seeds, creating a small cut in the seed’s shell may help. However, this is no miracle cure, and you’ll need to be careful to avoid damaging the inside of your seed.
IDEAL CONDITIONS FOR CANNABIS SEEDS
Humidity is easily one of the biggest threats to your seeds. Here is how different levels of humidity (% relative humidity) affect your cannabis seeds:
Many people forget this, but it’s true—your cannabis seeds are living organisms. Before they germinate, however, they are in a state of rest (much like some animals when they hibernate). And like all living things, seeds can die. When storing your seeds, you’ll want to give them the optimal conditions to ensure they hold through until you’re ready to germinate and plant them.
If your seeds get exposed to light or rapid changes in temperature, these conditions will trigger them to use up their nutrient stores before they ever see soil, meaning they won’t have the nutrients they need to germinate. High humidity, on the other hand, can trigger fungi to grow on your seeds.
