In this guide, we outline how to store and preserve your cannabis seeds. We focus on the following:
Keeping Light Away from Your Marijuana Seeds
Make sure your seeds remain away from light, as it can directly trigger germination.
What About Humidity?
Insects and pests also thrive in dirty storage areas. As a result, you must ensure the storage area remains clean. Otherwise, you won’t just attract pests to your seeds; microbes will form and damage the seeds. Do you want to consume marijuana from contaminated seeds?
If you provide the perfect conditions, marijuana seeds can be stored for up to 5 years and still be viable. If you give them decent conditions and maintain those conditions (i.e. no major fluctuations in the environmental conditions), you can expect the seeds to still be good after a year or two.
You can use them for short term storage, but you’ll want to find something better for a longer term solution. A vacuum sealed plastic bag that you put inside a glass jar is a great solution, however.
Seeds must be stored in the dark, because light triggers germination. If seeds are exposed to light, even if they do not have any of the other conditions required for germination, the chemical processes for germination are triggered.
To keep your seeds viable as long as possible, you need to store them in a cool, dark and dry location. The most important thing to avoid are fluctuations in the environment. You want to keep it as steady as possible. Here are the exact conditions you want to provide.
How Long Can You Store Cannabis Seeds?
You regular fridge gets opened constantly throughout the day. Every time you open it, the inside sees fairly large temperature fluctuations. The humidity level changes as well.
If you have no other option, at least put the seeds in the back of the fridge, where they are least affected by changes in temperature from the opening door. If there is a desiccant in the container with the seeds, the changes in moisture won’t affect the seeds either.
First we’ll cover the ideal condition for seeds, so that you can maximize their shelf life. Then we will cover all of the best containers and locations for actually storing seeds. We’ll also mention a few common ones that are less than ideal.
Glass jars, like mason jars, are ideal for storing seeds. Their one drawback is that most are not opaque, so you’ll have to keep them in a dark location or cover them with something, so that the seeds remain in the dark.
If a seed gets a steady supply of fresh oxygen, respiration can occur. This may lead to premature germination. To prevent this, store seeds in an airtight container. Inside a vacuum is ideal, but just somewhere that is sealed off is sufficient.
