Before your marijuana seeds germinate, they are in a similar state to animals when they hibernate. Like all living organisms, your seeds can die if you don’t take care of them correctly. The good news is that cannabis seeds can last for five years after harvest with proper storage.
If you want to store your seeds for at least six months, use a vacuum-sealed container. You can achieve this effect by removing all the air from a Ziploc bag. There are also special vacuum-sealed containers available online. Put the sealed bag in a dark container and put it in the fridge.
Keeping Light Away from Your Marijuana Seeds
For short-term storage, place the seeds in a container with desiccant. Seal it, and place it in a cool, dark place.
Also, you should note that modern fridges have low humidity levels. If the humidity is too low, your seeds will begin using up nutrients.
When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients.
Older seeds often have an extra tough outer shell. Gently scratching this shell with some sandpaper can help moisture and warmth enter your seed at the time of germination. Try gently scarring your old cannabis seeds just before soaking to help them sprout.
For long-term storage, it’s best to keep your seeds in a sealed container inside the fridge. Remember that opening the door of your fridge can actually cause some pretty dramatic temperature shifts. If you happen to have a second fridge that gets used less often than the one in your kitchen, use that one to store your seeds.
We’ve all found an odd seed somewhere at the bottom of an old drawer or cupboard. Here are a few tips on how to germinate old cannabis seeds:
CAN YOU STORE SEEDS IN THE FREEZER?
In a last attempt to germinate your seeds, creating a small cut in the seed’s shell may help. However, this is no miracle cure, and you’ll need to be careful to avoid damaging the inside of your seed.
Cannabis seeds have three main enemies:
For short-term storage, a dark cupboard or drawer with stable temperatures is usually fine. Try to keep your seeds out of areas of your house that are susceptible to the natural temperature changes of your local environment.
When you’re ready to germinate your seeds, inspect them and germinate any seeds with damage to the outer shell first. The outer shell of your seeds is designed to protect the volatile genetics inside. Seeds with cracks in the outer shell are a lot more vulnerable and shouldn’t be stored.
Another factor which can cause cannabis seeds to germinate prematurely is humidity. You see, weed seeds are fairly dry, and in order to split open, germinate, and start developing the root system, they need a good deal of moisture.
If you are going for long term storage, say more than a year, the best method is to vacuum seal the seeds using a vacuum sealer. This will remove all possible air, oxygen, and moisture from the equation.
Yes, cannabis seeds need oxygen in order to germinate, so, without oxygen present, they won’t germinate. Moreover, bacteria and all sorts of parasites all need oxygen too, so if you don’t want your seeds being infested by pests, keeping oxygen to a minimal level will be beneficial too.
Ideally, you want your cannabis seeds to be stored somewhere totally dark and not exposed to any light at all.
If your weed seeds are really pale in color, even white, or they look all shrivelled, chances are that they will not longer germinate.
One of the most important things to keep in mind is that temperature will cause seed germination, and super high temperatures may cause your seeds to rot from the inside out.
A humidity level of no more than 5% at most is recommended for both short term and long term marijuana seed storage. Yes, this can be hard to accomplish depending on where you live, but we will provide some tips for this later on today.
