How to store cannabis seeds!
The seed is not only alive, it is the beginning of everything: every new plant, every harvest. Whether you're a hobbyist or a professional, seed quality determines how your cannabis plants will develop, and this can affect your harvest when it's time to harvest it.
Therefore, how you store and protect your marijuana seeds is critical.
Storing cannabis seeds is a way to keep them viable for a long period of time. Proper storage can make the difference between high germination seeds and seeds that become sick, rot or die before reaching their germination potential.
When storing cannabis seeds, you want to prevent germination, but at the same time create conditions that will maximize germination when the time comes. Light, heat, and moisture all signal to seeds that it's time to germinate and grow.
The good news is that marijuana seeds are pretty easy to store: Just store them in a cool, dark, and dry place.
Let's talk storage containers
Ideal storage container
Temperature, humidity and light are the main factors to be controlled when storing cannabis seeds. However, before proceeding with this, it is necessary to select containers for storage.
If you're not going to use the seeds right away, it's best to store them in the original container and just find a cool, dark place. Some growers store cannabis seeds in plastic containers or even glass vials.
For short term storage, an envelope can be a good option. However, for long-term storage, the best storage containers are opaque, sealed, and made from the same material. For example, you should not choose a glass jar with a plastic lid.
Mixed-material containers are not ideal because different materials react differently to temperature changes, which means less control over storage conditions. Ultimately, you want as much control over the environment as possible.
Plastic is a little porous and doesn't meet sealing requirements for long-term storage, and airtight glass containers tend to be mixed materials.
One of the best storage solutions is a vacuum mylar bag: This is one material, it is opaque and the vacuum seal prevents moisture from entering. Glass containers with rubber stoppers are the only exception to the mixed materials rule and are recommended for seed storage.
Whatever you choose to store your cannabis seeds in, add something to keep the moisture levels low, like a bag of silica or uncooked rice wrapped in cotton or paper.
One of the most important variables to properly consider when storing and preserving cannabis seeds. If the humidity is too high, the seeds may begin to germinate before you're ready. Or, even worse, the hard outer shell of the seeds may begin to soften, reducing their viability.
Too low humidity is also undesirable. If the humidity is too low, your seeds will start to dry out and dry out. Remember that your cannabis seeds are alive and every living organism needs a certain amount of moisture to stay alive.
The ideal humidity for long term storage is somewhere in the 25-40% range - even then 40% can be overkill.
The good news is that you don't need to purchase special humidity measuring instruments. Because modern refrigerators are so dry that if you store cannabis seeds in the refrigerator, the humidity level will likely be normal.
Temperature is another variable that needs to be controlled when storing marijuana seeds. The main thing to remember is that
you want to maintain a constant cool temperature.
A dark cabinet or drawer can be a good enough option for short-term storage.
You can extend the shelf life of marijuana seeds by storing them in the refrigerator. Just as the refrigerator helps to reduce excess moisture, it is also a good place to store cannabis seeds, as the temperature in it remains consistently cold.
Sometimes it is recommended to use a freezer as a place to store seeds. Be careful with this option, as freezing the seeds can make them dry and brittle.
The last of the three main storage control variables for cannabis seeds is light. Light is a signal to seeds that it's time to grow and turn into a plant.
If short-term storage is planned in a closet or drawer, light may not pose much of a problem. If you choose this option, make sure you choose the darkest and least visited area in your home or nursery.
Again, room temperature is not always ideal, even for short-term seed storage. Refrigeration allows better temperature control. The problem here is that if you don't have the right storage container, your seeds can be exposed to light every time someone opens the fridge.

When trying to limit the amount of light that hits cannabis seeds, it's best to choose an opaque container. You can buy Mylar bags on Amazon, just make sure they don't have a transparent window.
If you choose storage glass, it is best to purchase amber or cobalt colored glass to limit exposure to light. Alternatively, you can wrap the glass jars with something opaque and be done with it.
Treat growing and cultivating cannabis as a kind of scientific experiment. Even deciding how to store seeds can be part of this process.
If you find that your seeds are not germinating or producing the desired yield, play with the variables to get the right conditions. If your seeds seem too dry, check to see if your container is really airtight. If the seeds seem to germinate too early, check the temperature and humidity levels.
If you store your seeds in the freezer and find that the outer layer has cracked when it's time to germinate, that's a sign that the freezer isn't the best storage option. You may even find that different seed varieties respond differently to the same environment.
