How to store weed seeds?

Once you have received your ordered cannabis seeds, most growers start their grow right away. After all, your seeds are fresh and you want to prevent the cannabis seeds from germinating in an uncontrolled way. However, if you can not or do not want to start with your cultivation immediately it is important to store your seeds properly. When storing your seeds properly, your seeds remain fresh and viable.

Curious how to store your cannabis seeds and how long you can preserve your weed seeds? Read on and let us tell you how to store weed seeds!

General rules for storing cannabis seeds

Keep in mind that marijuana seeds are living organisms. When the seed makes contact with water, the nutrients in the seed that trigger the germination process will be released, so to prevent unused cannabis seeds from germinating or getting damaged, you have to keep your seeds in a cool, dark and moisture-free place. Cannabis seeds can withstand very low temperatures, but air humidity and fluctuations in temperature should be avoided at all times.

Below you find more information about the best way to store weed seeds for a short and long term.

How to store cannabis seeds for a short term?

The best way to temporarily store weed seeds (several days, weeks or months) is to place the seeds in a dark, lockable (plastic) container in the refrigerator.

Please note: once you have decided to use the marijuana seeds, place the seeds in the box for 6 hours outside the refrigerator so the seeds calmly reach room temperature.

How to store cannabis seeds for a long time?

Of course it’s also possible that you have bought several cannabis seeds and that you want to keep a part for, for example, next year. The best way to store cannabis seeds for a long term is to freeze the seeds. Make sure you vacuum pack the seeds, place the seeds in a dark lockable (plastic) container and put them in the freezer. If done right, you can store your seeds for years.

Note: seeds that are stored in the freezer should be germinated immediately after you take the seeds out of the freezer. Do not let the seeds thaw first.

How long can you store marijuana seeds for

You can store your seeds in the refrigerator for up to a year. When freezing, the seeds remain viable for up to 2 years and even longer.

How To Properly Preserve Cannabis 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.

YOUR SEEDS ARE ALIVE

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.

IDEAL CONDITIONS FOR CANNABIS SEEDS

Cannabis seeds have three main enemies:

  • Light
  • Humidity
  • Temperature changes

Ideally, you want to store your seeds in a cool, dark, and dry place. Whenever possible, keep your seeds in their original packaging. At Royal Queen Seeds, we’ve specially designed our packaging to protect our seeds until you’re ready to plant them.

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.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

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

WHERE AND HOW TO STORE YOUR CANNABIS SEEDS

For short-term storage, a dark cupboard or drawer with stable temperatures is usually fine. Try to keep your seeds out of areas of your house that are susceptible to the natural temperature changes of your local environment.

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.

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.

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.

Ziplock bags, for example, are great because you can remove all the air from them to create an almost vacuum-sealed container for your seeds. Once vacuum-sealed, put your bag inside a dark plastic bag or dark container to protect your seeds from your fridge light.

Remember, modern fridges are very dry. It’s super important your seeds aren’t directly exposed to these conditions, as the lack of humidity can cause them to use up their nutrient stores just to stay alive.

CAN YOU STORE SEEDS IN THE FREEZER?

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.

KNOWING WHICH SEEDS TO PLANT AND WHICH TO STORE

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.

At Royal Queen Seeds, we take pride in our work and want to ensure every grower only has the best genetics in their garden. That means we inspect all of our seeds before packaging. If you notice any damage to your RQS seeds, get in touch with our customer service team immediately.

TIPS FOR GERMINATING OLD CANNABIS SEEDS

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:

  • Pre-soakingwith enriched carbonated water

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.

  • Scaryour seeds

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.

  • Remove a seed’s ridge

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.

  • Slice openyour seed

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.

Remember, some old seeds just won’t germinate no matter how much you try. Whenever possible, avoid buying more seeds than you plan to plant so as to avoid having any issues at the time of germination.
