Do you like growing cannabis plants and don’t know how to get started! Here is what you need to know about Cannabis - growing, storing the seeds, factors affecting seed germination, and much more. Let us dive into the topic!

How to Store Cannabis Seeds

Before purchasing the seeds online, it is essential to know the key factors like how to store cannabis seeds for long-term and short-term? What temperatures does it support? Harvesting tips, and precautions. Now, let us get into the parameters that affect the growth of seeds under certain conditions.

Cannabis Seeds Storage Conditions

  • Temperature
  • Sunlight
  • Humidity levels
  • Pet-free storing locations
  • Cool, dry and dark climatic conditions
  • Placing cannabis seeds in the freezer 
  • Keep insects and rodents away from cannabis seeds
Climatic Conditions - Cold, Dry and Dark

Once you purchase cannabis seeds from local stores or online platform, it should be kept in optimum climatic conditions, i.e., cold, dry and dark. It’s an individual choice to store the seeds in a refrigerator, freezer, cabinets or drawers and keep them protected until the seeds germinate.

Also, make sure the seeds should never be exposed to the direct sunlight as it leads to premature seed germination. Ideally speaking, 7-9% of the sunlight and humidity (dry or the dark place) is preferable.

If there is an excess humidity level in your area, the seeds may damage quickly. So, it's better to control and maintain the humidity levels to low by using sealable containers or airtight plastic bottles.

High temperatures may diminish the process of seed germination. Hence, most of the growers prefer to store the seeds in the refrigerator for quick germination. The ideal temperature to store the seeds is between 6-8C. And if you do not want the seeds to damage, it is good to place them around 20-30% of humidity levels.

Sunlight is yet another important factor one must consider for securing the seeds. It is because the direct sunlight may trigger seed growth by losing the germination functionalities. Hence, it is preferred to protect the seeds by covering up with a transparent sheet or by placing in a dark place for long-lasting.
Keep Insects Away from Cannabis

Further, if you do not properly reserve the seeds; insects, rodents may spoil the seeds and make useless. To avoid such loses, spill DE (Diatomaceous Earth- a combination of sand and fossilized algae) on the surroundings. It acts as a natural insecticide and is non-toxic too. Apart from that, you can also place the seeds in a well-ventilated area to deter pests.

Once you’ve done storing, label them on the container or bottle so that you won’t get confused with other plant seeds like marijuana.
