Keep your cannabis seeds in good shape

Simple Tips to Keep Your Cannabis Seeds in Good Shape

The attention you give your cannabis seeds will decide how well your plants develop and how successful your harvest will be. Because we’re dealing with a natural product that needs to mature, the conditions in which it’s stored will affect its eventual yield. Even though marijuana seeds are tough and self-sufficient, you need to take action immediately if you want to prevent problems when planting them.

Below are some simple but useful ways you can keep your cannabis seeds in perfect condition.

Labelling the Seeds

This is an important thing to note: don’t forget to label the many strains you have. It would be best if you only opened the containers to plant the seeds once they have been stored. It’s not ideal for opening and closing the container you are using because the protection provided to your seeds is quickly lost as it is opened. Temperature and humidity changes can also be harmful.

If you can’t see the seeds, labelling the strains you have is even more important. This could be the case if you take some growers’ advice and store your seeds in analogue film tubes. It can be as simple as slapping a little label on it and writing the name of the strain in each tube with a pen or marker. Each tube should then be placed inside a piece of secure container to protect its contents from deteriorating.

Ideal Storage Temperature

The ideal temperatures for storage and germination of your cannabis seeds are 6° C and 24° C, respectively. To calibrate the range in which you work, take note of these two temperature restrictions. Keep in mind that the best temperature for storing seeds is between 6° C and 8° C.

The most experienced producers have a refrigerator dedicated to this function, with low temperatures maintained at all times. The same is true in terms of humidity.

If you don’t want your seeds to be damaged, keep them somewhere with a relative humidity of around 20-30 per cent. To keep your seeds cool, all you have to do is make room in your refrigerator. However, ensuring that it’s dry enough for good preservation will be a bit more difficult.

Humidity Control

It’s a good idea to have some sealable containers on hand to keep humidity levels low for your cannabis seed storage spaces. Eppendorf tubes are a highly recommended solution for this.

These tubes are a standard piece of laboratory equipment used to store liquid samples. They’re distinguishable as small cylindrical polypropylene containers with conical bottoms and hermetic sealing. This method of micro conservation protects individual seed containers in such a way that, regardless of changes in the outside environment, the humidity levels inside the container remain consistent.

You can insert little pearls of silica gel into the tubes, ensuring that the air inside remains perfectly dry even if the outside humidity rises or the temperature changes. The Eppendorf’s cap ensures that no humidity gets in, but the silica gel assures that any that does get in will be quickly absorbed by this material.

If you don’t have any of these containers, some opaque and sealed plastic bottles would suffice. Along with the seeds, some dry rice or silica crystals should be placed inside. Be sure to separate the seeds using a cotton ball or paper. These elements will absorb moisture from the atmosphere, which can range from 25 per cent to 100 per cent, depending on your location.

Light Control

It’s important to remember that light is another aspect that has a direct impact on seed germination. As a result, you must ensure that light does not shine on the seeds that you will subsequently plant. They lose a lot of their germinative power when exposed to light. You can keep your seeds for several years if you follow these tips. Some scientists even believe that under perfect storage circumstances, seeds can live up to a decade.


While storing cannabis seeds properly takes a lot of care, making sure you address specific concerns such as light, temperature, and humidity will reward your efforts with healthy seeds ready for planting. If you’re still a newbie to the cannabis industry, it can help if you approach experienced growers and ask for more advice.
