The goal is to thin out the shell so that the water can reach the embryo easily, just make sure you don’t overdo it and end up harming the embryo inside.

Sprinkle a little bit of water if needed, you’ll know they’re ready to be transplanted when the radicle is around 1-3cm long.

Step 1

Remember that some seeds may need longer until you see the radicle coming out.

Place the seeds on the paper towel, fold it over the seeds and place it in a plastic container, cover it with the lid to keep moisture in (can also use two plates instead of the plastic container, place the paper towel on a plate and use the other one to cover).

Rockwool cubes are small cubes made of rock and sand fibers, with the consistency of cotton candy almost, they absorb a lot of water and usually are used for germinating seeds and clones.

This method is the least stressful for the little seedling as you don’t move it around and the soil acts as a buffer if there are any temperature or light fluctuations.

Autoflowering cannabis seeds are just like any regular ones and the process of germination is the same, in fact, the only differences are in the way you treat you seedling when it has sprouted. Some growers say that autoflower seeds can be germinated in colder temperatures but I have not tested this hypothesis myself and have not seen side by side tests that show temperature differences and autoflower seed germination rates.

Natural autoflower seed germination

Just take your autoflower cannabis seed and put it in a wet growing medium 2 to 3 times as deep as the width of the seed. That little plant will shoot its tap root down into the ground and with those seed leaves will try to find the light.

Germination temperature

If you tried to germinate your seeds and some of them did not crack open after 5 days or more you have one last hope and it is to gently try to crack open the seed shell hoping not to damage the seedling if it is still alive.
