#75The lower the temperature, the less likely your seed is to germinate. However humidity plays in this too.
<8%: The seeds will attract insects and other pests.
9 – 20%: Your seeds are more likely to develop fungi inside and out. They begin sweating at below 20% humidity. However, 8-10% is a ‘sweet spot’ for long-term storage in the right conditions.
21 – 30%: The ideal humidity level for cannabis seed storage.
31 – 60%: This is the germination zone, particularly once the humidity level goes past 40%.
61%+: You are endangering your seeds the higher the
humidity level goes.
Once it reaches 80%, your seeds will wilt and die in approximately 12 hours.
If you want to store your seeds for at least six months, or longer, 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.
You also have the option of placing the seeds in the freezer. Remember, though; you need to germinate them immediately upon removal.
You must keep your seeds in a location that is cool, dark, and dry. It is best if you keep the seeds in their original packaging. When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients.
Cold. Dark. Dry. That’s all is needed really. Don’t use moisture absorbers. They will dry the seed out beyond repair.
I would love to grow Afghan… I’ve heard it’s wonderful for making dabs
