how to keep marijuana seeds fresh

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.

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.

If you’re storing your seeds in a humid, improperly sealed environment with access to moisture, your seeds may rot, mold or prematurely germinate. Once water comes into contact with a seed, it produces ethylene and begins to germinate. Even just a little droplet can cause harmful mildew that can kill your seeds. Aim for an environment of 10 to 20% humidity and use a desiccant. Seeds can begin to germinate at just 40% humidity.

3. Keep the temperature constant

Labelling your seeds is crucial. This will stop you from opening your containers to check them and will provide details on both strain type and date of purchase. You can write all this simply on a small paper label and place it on the container’s exterior. Dates will ensure you can plant for freshness.

You’ve received a package of your favorite high-quality 10 seeds (from us). You’ve planted 5 of them for this season and are waiting to plant the next 5. What do you do? Store them. After all, proper storage is an essential part of being a good grower. Here’s why:

Light is one of the biggest factors that contributes to seed germination. Overexposing your seeds with too much light will force them to leave their dormant stage and begin to mutate. This is particularly true of constant fluctuations in light, which will affect the germinating power. You may end up with a seed that either grows poorly, takes far longer to grow than normal, or simply won’t grow at all. That’s why opaque containers are so important.

Cannabis seeds are naturally pretty resilient, but they aren’t invincible. Changes in temperature, humidity and light can all have very damaging effects. More drastic environmental issues, like dampness, can even destroy your seeds completely.

You must keep your seeds in a location that is cool, dark, and dry. It is best if you keep the seeds in their original packaging. When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients. This is a disaster because they ultimately won’t have the nutrients to germinate.

You also have the option of placing the seeds in the freezer. Remember, though; you need to germinate them immediately upon removal.

What’s the Right Storage Temperature?

For short-term storage, place the seeds in a container with desiccant. Seal it, and place it in a cool, dark place.

You now understand that you must store the seeds away from direct light. We have also outlined the need for relatively low humidity and a refrigerator-level temperature. Different options are available depending on how long you intend to store the seeds.

Also, you should note that modern fridges have low humidity levels. If the humidity is too low, your seeds will begin using up nutrients.

We’ve all found an odd seed somewhere at the bottom of an old drawer or cupboard. Here are a few tips on how to germinate old cannabis seeds:

The ridge is the slightly elevated side of your seed. Like other parts of the shell, this ridge can become extra tough over time. Removing it gently with a sharp Stanley blade can help your seed sprout.

Humidity is easily one of the biggest threats to your seeds. Here is how different levels of humidity (% relative humidity) affect your cannabis seeds:

CAN YOU STORE SEEDS IN THE FREEZER?

Cannabis seeds, with their tough outer shell, seem pretty hardy. And while nature has definitely designed them to hold up to a wide variety of conditions, cannabis seeds aren’t invincible. Rapid changes in temperature and high humidity, for example, can quickly ruin a batch of seeds. Luckily, caring for your seeds is simple. Keep reading to learn how.

If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.
