how to preserve 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.

Before germinating your old seeds, try soaking them in carbonated water enriched with fulvic acid, germination booster, hydrogen peroxide, or gibberellic acid. For best results, use room temperature water and soak your seeds for 12 hours in a dark place.

YOUR SEEDS ARE ALIVE

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

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.

Again, whenever possible, keep your seeds in their original packaging. If you do open a pack of seeds and have leftovers, transfer the extra seeds directly into a sealed airtight container.

Whatever your reason may be for having seeds, remember that taking care of them is one of the most important things you can do for your harvest. A badly stored seed may not germinate, and if it does it may not grow properly.

Humidity is another incredibly important factor that can determine the success rate of your seeds as humidity is essentially what causes seeds to germinate. You don’t want them accidentally germinating, if they reach a certain humidity level they may start absorbing nutrients and end up too weak to grow normally, so you want to keep them in a relatively dry place.

3. Ideal Conditions for Storing Seeds

If you’re storing your seeds for a couple of months it’s better if you store them in the refrigerator. This will guarantee the seeds don’t suffer from temperature swings. By keeping them in their original package or in a light-proof container you ensure they will be good for as long as you need.

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.

Usually, the package they come in is light-proof and water-proof, as long as you leave them in a relatively cool place like a drawer or something similar they will be good.

A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.

Some people who live in regions where there is a lot of cannabis activism and reform are currently stockpiling seeds of their favourite strains to grow when it’s legal in the future. Whatever your reason may be for having seeds, remember that taking care of them is one of the most important things you can do for your harvest.

WHY IS PROPER SEED STORAGE NECESSARY

As mentioned above, seeds require cold temperatures so they don’t lose their essence. Either freezing or refrigeration will do. However, when keeping seeds in the refrigerator, keep them as far back as possible so they won’t be exposed to any temperature changes when the door is opened.

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.

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.
