best way to store marijuana seeds

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.

Cannabis seeds can withstand very low temperatures, but air humidity and fluctuations in temperature should be avoided at all times. 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.

When storing cannabis seeds properly, your seeds remain fresh and viable. Curious how to take care over storing cannabis seeds, and how long you can preserve your weed seeds? Read on and learn how to store weed seeds!

Storing cannabis seeds for a long term

To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.

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.

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.

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 the seeds properly.

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.

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.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

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.

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, 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.

These are small cylindrical containers with conical bottoms, made of polypropylene, and with hermetic seals. With this method of micro conservation the containers full of seeds are protected individually, in such a way that, even if there are variations in the outside atmosphere, inside the container the humidity conditions are constant.

Note these two temperature limits to calibrate the range in which you operate. Keep in mind that the ideal temperature to store seeds is around 6 to 8° C. Hence, the most expert growers have a refrigerator just for this purpose, with low temperatures being constantly maintained. The same is true with regards to humidity: if you do not want your seeds to suffer any damage it is advisable to keep them in places with a relative humidity of around 20-30%.

Humidity control via micro conservation in Eppendorf tubes

Another threat that can ruin all your efforts are insects. Just one in your container is enough to render all the seeds inside useless. To prevent this it is advisable to spread diatomaceous earth where you store them. D.E. is a kind of sand with a fossilised algae base. It is inert and non-toxic, and functions as an invaluable natural insecticide. If you keep your seeds in your fridge with other foods, this will not be a good place to use this type of substrate. However, if you have a refrigerator just for this purpose, or a simple closet, you will be able to use this trick.

To keep your seeds in a cool place you’ll only have to make some space for them in your refrigerator at home (if it is a no-frost model, and in the fruits and vegetables crisper, even better), though ensuring that it is dry enough for their proper preservation will be a bit more complicated.

To ensure this we place small pearls of silica gel inside the tubes so that, even if the outdoor humidity rises, or the temperature varies, we can be confident that the air is completely dry inside. The cap of the Eppendorf guarantees that no humidity gets in, but the silica gel also ensures that, if any were to penetrate it by accident, it would be immediately absorbed by this material.
