Germination is key to start our cannabis cultivation on the right foot. Therefore, any self-respecting cannabiculturist must know everything about this process: from the optimal conditions and means for the cannabis seed to germinate to the first care of the seedling. After reading this article, you will discover that beyond taking your marijuana seed and putting it in water or in the ground, there are a series of steps that you must take into account if you want your plants to grow strong and healthy.

Germination conditions

First of all, to activate the process, we must put the seed in contact with water. The liquid enters its interior until it reaches the embryo. Then, the seeds swell and what is called a germ appears, which in a few days will become what we will call a seedling.

This small bud is highly sensitive, so it will need to be treated carefully. There are even experts who recommend not to manipulate it until they reach between 5 and 10 millimeters. Also, the seed itself requires careful handling, and you must avoid not touching it with your hands. The most recommended is to use tweezers to catch it.

In addition, as we have already pointed out, the use of water is critical in the process. Now, you have to be precise with the quantity. One must not overuse water or fertilizers. Believing that these will accelerate growth is a mistake, and its use is not even recommended until after the first three weeks after the plant germinates. This is because the abuse of nutrients could burn the plants, as they are weak in these early stages.

As for the water, you can use the tap. Some cannabis growers, to ensure that their levels are correct, add a few drops of hydrogen peroxide. This manages to increase the amount of oxygen, in addition to eliminating fungi and bacteria that affect the process thanks to its antifungal properties.

Also, pay attention to temperature and humidity. For this, the ideal environment should be between 20 and 25 ºC, with humidity percentages between 70 and 100%. Furthermore, the entire process should preferably be done in the dark. Exposing the seed to a direct light source could slow down germination and will only be allowed when cotyledons begin to appear, that is, the first leaves of the seedling.

Finally, you have to be patient. There is no standard period after which the seeds begin to germinate. Of course, if you do everything correctly, you will soon see the outbreaks. Still, don’t despair if it takes a little longer than expected.

Care after germination

We may have made our seeds germinate, but not with the best result. Cotyledons sometimes have a hard time getting out, or the shell (or its thin inner membrane called the cuticle) does not come off. In these cases, we must help them out. To do this, with the help of tweezers, we will gently remove the shell so that the cotyledons open freely.

Thus, when the seedling has the precise size, we can transplant it into the culture medium. In it there should be light, heat and humidity, which will favor the growth of the foliage.
