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.
To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.
How to store weed seeds?
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.
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.
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.
The temperature at which you store your seeds is quite important. You’ll need to store them at around 6-8 celsius. You can keep them in your home fridge or even your freezer (however it’s usually not necessary).
Before talking about how to store seeds we need to remember you that your cannabis seeds are alive. Before they germinate they are kind of in a state of hibernation, and like all living things, they can die.
If there is as low as 8% humidity in the container it can cause fungi to appear inside and outside your seeds, at 40-60% your seeds will sprout and beyond that, they can drown in less than a day.
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.
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.
When stored under perfect conditions, cannabis seeds can be viable for up to 10 years successfully. Seed storage is important for many reasons, either you’re a home grower waiting for the special occasion to grow that unique strain you just bought or seedbanks who need to stock seeds for the eventual sale.
Tip: When storing seeds in the fridge or freezer you can add silica gel sachets to ensure they’re completely dry.
