storing weed seeds in the fridge

When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients.

Here is a quick overview of what will likely happen to cannabis seeds at different humidity levels:

What’s the Right Storage Temperature?

The best temperature to store your cannabis seeds at is between 43- and 47-degrees Fahrenheit. The lower the temperature, the less likely your seed is to germinate unexpectedly. Experienced growers tend to have special refrigerators to store their seeds. Ideally, your fridge is a no-frost model. If you can place the seeds in the fruit and vegetable section, that is even better.

Imagine paying $100+ for seeds, going to the trouble of storing them, only to find that insects ruin them. Unfortunately, all you need is one insect in a container to destroy all of your seeds. The first consideration is to avoid exposure to ultra-low humidity. However, for long-term storage, this is precisely what you are supposed to do!

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

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.

YOUR SEEDS ARE ALIVE

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.

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.
