First we’ll cover the ideal condition for seeds, so that you can maximize their shelf life. Then we will cover all of the best containers and locations for actually storing seeds. We’ll also mention a few common ones that are less than ideal.

The ideal temperature is between 42° and 46° F, which is approximately 6° and 8° C. You can certainly store them in warmer temperatures, but it will reduce the shelf life. If you plan on keeping them for a long time without germinating them, you’ll want to keep them cool.

When putting desiccant in the container with the seeds, it is best to keep the two separate. You can create a boundary between the weed seeds and the desiccant by using wool or cotton.

Seeds are best stored in a cool, dry, dark location. That basically describes a fridge. With one caveat. You can’t open the door all the time.

Before you seal your container up tightly, make sure to check it carefully for pests. You do not want a single insect in the jar with your seeds, because it could potentially do serious damage to them. Once you’ve confirmed the container is pest free, seal it up tightly to ensure it stays that way.

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.

Yes, cannabis seeds can be stored in the freezer. The lower the temperature, the slower they decline. However, it’s usually not necessary to freeze your seeds. Meet the conditions we outlined above, and you should be able to preserve your seeds for up to five years and still get a high germination rate.

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.

KNOWING WHICH SEEDS TO PLANT AND WHICH TO STORE

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:

When you’re ready to germinate your seeds, inspect them and germinate any seeds with damage to the outer shell first. The outer shell of your seeds is designed to protect the volatile genetics inside. Seeds with cracks in the outer shell are a lot more vulnerable and shouldn’t be stored.

Older seeds often have an extra tough outer shell. Gently scratching this shell with some sandpaper can help moisture and warmth enter your seed at the time of germination. Try gently scarring your old cannabis seeds just before soaking to help them sprout.

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.
