At this point, you can transplant the seed into its pot. Use a pair of tweezers and handle each seed carefully, being careful not to touch the taproot. The taproot is fragile and may break if you’re not delicate; furthermore, touching it with your hands may contaminate it.
After germination, you’re good to go. Remember to check back as the plants mature to make sure you haven’t got any male cannabis plants.
Disclaimer: Don’t perform this test unless you’re ready to germinate the plants right away. The water could damage the seed and ruin a perfectly healthy plant if you dry it out afterward.
Method #4: The Germination Test
There are several easy methods for testing cannabis seeds. Most of them can be performed before germination, saving you some time and resources. Let’s find out how to check your seeds.
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.
Cannabis seeds are surprisingly beautiful. They have a mottled brown appearance with patches of light and dark, and sometimes gorgeous tiger stripes. The seeds are also quite shiny if you view them close enough.
The sign of a bad seller is that their seeds are consistently old, dead, and covered in powdery mildew. That said, don’t be too harsh on a seed bank if a couple of their seeds don’t work from time to time when they’re generally reliable.
I think it is both overwatering and the light being way too close.
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.
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.

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
Removing the ridge not only makes it easier for the seed to open, it helps with water absorption.
In a life or death situation, surgery may be the only option. Meaning—only do this if nothing else has worked because this technique ruins as many seeds as it saves.
Scarification, or scuffing the shell, can also help water pass through an older seed’s tough outer shell.
3. REMOVE THE RIDGE
As cannabis seeds age, their protective outer shell hardens and prevents water from passing through. Unless the tiny, dormant embryo that lives inside the shell detects moisture, it doesn’t know that the conditions are right to sprout. As a first step, pre-soak your old cannabis seeds for about 12 hours to see if that does the trick.
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.
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.
As you proceed through these steps, the risk of damaging your seeds past the point of recovery increases. Between each suggestion, give them a few days to a week to germinate. Allow the outside to dry each time to prevent rot. Do not try all or multiple techniques at once.
