If you’re going to keep seeds more than a year or two, proper storage will dramatically increase the chances of late-stage germination. Place them in an airtight container. Put the container in a refrigerator set at 6–8°C with 20–30% relative humidity. If excess moisture is a concern, add silica gel packs to the container.
To improve your chances, use carbonated water and/or add one of these supplements that help with water absorption. Fulvic acid and most boosters also give your seeds a light dose of nutrients.
To scarify your seeds, line a matchbox or other small container with sandpaper. Drop the seeds inside, shake vigorously for 30–60 seconds, then remove. You may not notice much of a difference, but the small micro-abrasions are sometimes enough to let water breach the shell and trigger germination.
4. SLICE THE SEED
The older a cannabis seed gets, the harder it is to pop. But hard doesn’t mean impossible. If you’ve been saving your seeds for a rainy day and it finally started pouring, these tips could help you get most, if not all, of your old beans to germinate.
Removing the ridge not only makes it easier for the seed to open, it helps with water absorption.
Keep the water warm, but not too hot. Aim for around 22°C. Avoid direct sunlight, and keep an eye on the glass. Do not soak seeds for prolonged periods, more than 24 hours can deprive them of oxygen and make them drown.
When your old cannabis seeds don’t want to pop, one of these four techniques could come to their—and your—rescue. Aging seeds are more difficult to grow than fresh ones and we’ll explain what you can do to help germination.
I think it is both overwatering and the light being way too close.
So, I first want to say thanks to everyone here who is always helping peolpe with their questions. I’ve read many forums and threads and without you guys’ help I would be even worse at this. I’m a COMPLETE Noob and this is my first grow ever.
I got 3 LR2 x AK47 seeds from Attitude and germinated 1 of em (Paper towel method). I then got a 8 1/4" pot, which I think may be entirely too big, after filling it with Fox Farms Ocean Forest and watered thoroughly (all extra drained water I disposed of) then I put the seed about half an inch under the moist soil and put it in my closet. There’s a fan that cirulates air and the light was put about 2" from the soil. First day after 18 hour light with a 125Watt 5u CFL, nothing. Second day, nothing, but I looked at the seed and the taproot was green but the tip was a light brown. This morning after another 18 hours, the seed shell is a light brown, and the plant inside the shell looks crispy almost. I moved the light a few inches away from the soil after making sure the soil was moist again (Seed was taken up anyway to see its "development") I’m not sure if this is overwatering or heat? I tried to make sure to have a balance, but the top of the soild and about an inch down just seemed so dry.

Forget the paper towel, just pop the seed in damp soil and leave it alone – too many seedlings are killed by growers – they know how to grow without us screwing them up
Today, we will help you work out whether your cannabis seeds are good or bad. Hopefully, this guide will help you to determine which seeds are worthy of your time and which ones are duds.
Unfortunately, you might still get some bad seeds sometimes. Plants are living beings and can be a bit unpredictable – even the seller might not be aware that some of their seeds are duds. With any luck, the majority of seeds you buy will be healthy and good to go.
What Makes a Cannabis Seed ‘Bad’?
A ‘bad seed’ is any cannabis seed that will cause problems. In some instances, this means a dud seed that never sprouts, wasting your valuable time and a few resources. While dud seeds aren’t damaging, they are irritating.
Telling good and bad cannabis seeds apart is not an exact science. Sadly, you don’t know what’s inside the seed beyond its appearance, so you won’t know what the plant is truly like until you start growing it.
