For long-term storage, it’s best to keep your seeds in a sealed container inside the fridge. Remember that opening the door of your fridge can actually cause some pretty dramatic temperature shifts. If you happen to have a second fridge that gets used less often than the one in your kitchen, use that one to store your seeds.
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.
EFFECTS OF HUMIDITY ON CANNABIS SEEDS
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.
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.
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.
With the correct method of storage, cannabis seeds could remain viable for 5-10 years! Seed storage is important for many reasons. Someone who just created their own, high-quality genetics, may want to keep the seeds to reproduce the strain.

WHY IS PROPER SEED STORAGE NECESSARY
A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.
Frequent inquiries from new growers are often related to cannabis seeds. How can they be stored safely? How long will they last in storage? Will they retain the same qualities as newer seeds? When stored appropriately, yes, you can grow prime cannabis plants with decade-old seeds, just as you could with seeds that are only a few months old.
If only being stored for a few months, cannabis seeds should do fine in a grip-seal bag, placed in a mason jar or some other type of airtight container. For more long-term storage, a vacuum-sealed package is a much more popular option. Many seasoned seed-savers like to add a food-grade desiccant to their package as well.
After the hard work of germinating your seeds, it may be tempting to just toss your leftover beans in a bag for next time. However, you may be in for a rude awakening when it comes time to germinate your next batch. If stored improperly, cannabis seeds may no longer be suitable for planting.
The humidity and temperature of your storage environment are perhaps the most important factors. Cannabis seeds will absorb moisture from particularly humid environments and will dry out in particularly dry ones.
Why Is Proper Cannabis Seed Storage Important?
If stored correctly, cannabis seeds can still germinate up to 5 years or more after being harvested. Growers should be careful to protect their seeds from light and oxygen, as well as fluctuations in temperature and humidity. Read on to find out how and where to store your seeds for optimal preservation.
Ideally, you should stick to glass containers whenever possible. Glass containers are excellent for both short-term and long-term seed and bud storage. Just don’t forget to cover them up so as to protect your seeds from light.
The ideal temperature for storing cannabis seeds is between 6–8℃. It is believed that the lower the temperature, the slower their vitality and ability to germinate decreases. For this reason, many large-scale growers choose to keep their seeds in a refrigerator specifically set to this temperature range. If the humidity level is appropriate, you may even be able to store them in a cool, dark corner of the fridge in your own kitchen.
