Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.
To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.
The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.
WET KITCHEN TOWEL METHOD
Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.
Regardless of where you get your seeds from, it is best to give them a slight (and delicate) inspection before planting. Most of the time, all seeds will germinate; however, poor-quality seeds will produce a weaker plant. Unfortunately, that is something you will not find out until well into the vegetative and flowering stages.
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
The last method is just taking a small knife or scalpel and cutting around the seed till the seed shell breaks off, but you should be very careful not to damage the seedling if it is still alive.
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.
There are basically two methods of germinating autoflower seeds and they are natural seed germination and germination without growing medium. In nature autoflowering cannabis seeds usually drop down in the autumn, then they survive the winter and in the spring when the temperature reaches optimal level and the surrounding area gets moist they start to germinate. Autoflowering seeds don’t like overly wet conditions and if the seeds drop into a puddle or any other water reservoir or even a swamp then they usually start rotting and die. Looking from the other extreme when a cannabis seeds germinate it looks for a wet environment and if the tap root encounters a dry environment it shivers and dies. From the environments that these seeds encounter in nature we can see that they need to be really strong to survive different conditions and that is why autoflower growers in perfect conditions can achieve more than 99% seed germination.
One of the disadvantages is that you cannot control every aspect of this germination process and you can’t know which seeds will germinate and which won’t.
You also need to put your seed germination tray in a dark room and twice a day check if the paper towel has not dried yet. I will give an autoflower germination guide (wet paper towel method) at the end of this article.
This method requires a lot more work than just putting seed into the ground. Basically there are more things that can go wrong.
This not knowing also creates a need for more pots and ultimately can cost you money because some seeds will not germinate and you can’t tell which will, but you need to plant each of them inside a different container.
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).
Have in mind that it’s possible to drown the seed, so we need to keep an eye on moisture levels, also making sure it doesn’t dry out.
Using them along with the germinating chamber has an advantage, being easy to transplant to the next medium or container.
You can place the pellet or cube directly in any type of medium or hydroponics chamber, after sprouting, the roots will continue to grow down, even if they reach the end of the Rockwool or peat pellet.
As you may know, cannabis plants need certain conditions depending on the stage they’re in, maintaining these conditions are the best way to ensure your plants will thrive, and when talking about seeds and germination, it’s no different.
Place the container in a slightly warm and dark place.
