Remember, modern fridges are very dry. It’s super important your seeds aren’t directly exposed to these conditions, as the lack of humidity can cause them to use up their nutrient stores just to stay alive.
If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.
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:
EFFECTS OF HUMIDITY ON CANNABIS SEEDS
Cannabis seeds, with their tough outer shell, seem pretty hardy. And while nature has definitely designed them to hold up to a wide variety of conditions, cannabis seeds aren’t invincible. Rapid changes in temperature and high humidity, for example, can quickly ruin a batch of seeds. Luckily, caring for your seeds is simple. Keep reading to learn how.
Yes, cannabis seeds can be stored in the freezer. The lower the temperature, the slower they decline. However, it’s usually not necessary to freeze your seeds. Meet the conditions we outlined above, and you should be able to preserve your seeds for up to five years and still get a high germination rate.
If your seeds get exposed to light or rapid changes in temperature, these conditions will trigger them to use up their nutrient stores before they ever see soil, meaning they won’t have the nutrients they need to germinate. High humidity, on the other hand, can trigger fungi to grow on your seeds.
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.
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.
Therefore, when storing your cannabis seeds, put them in an opaque container which does not allow any light in, therefore keeping the seeds away from light. Make sure that this opaque container is stored in a cool place.
Keeping them cool will also ensure that they are not exposed to too much heat which can damage them. Keep them in a cool place, and some people do use the fridge or freezer, something which we will touch on later today.
Use A Plastic Bag
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.
On that same note, even if the seeds do not germinate, excessive humidity can cause the seeds to literally rot, which will make them totally unviable for germination. Therefore, you need to keep them somewhere very dry.
First, let’s go over the 4 main factors which can cause cannabis seeds to germinate early, which for the most part are also the same factors which can cause them to take damage, to rot, and to become totally unviable for germination.
Ideally, you want your cannabis seeds to be stored somewhere totally dark and not exposed to any light at all.
