5 Common Mistakes When Germinating Cannabis Seeds – Philosopher Seeds
While germinating cannabis seeds is a relatively simple and quick process, there are a number of important factors to consider in order to achieve the highest possible germination rate. We are also interested in germinating the seeds as quickly as possible, but above all, without any problems, such as fungal infection or a too low germination index.
In our article on how to germinate marijuana seeds we already explained step by step what you need to do to obtain a successful germination. Today we offer you to know the main errors made during this process, errors which, as we will see, can be solved very easily. We will then see why many growers fail when it comes to germinating their seeds, a good way to learn what not to do if we want to get the most out of our seeds.
Let the germination medium dry
By putting the seed in a moist culture medium, a whole series of reactions, allowing it to germinate in a few hours or days, will then begin. Whatever substrate we use to carry out the germination, we must ensure that it never completely dries out, because most likely the seed will cease its activity, no longer being able to capture humidity in the surrounding area, and therefore will never germinate.
In this way, it will be necessary to check daily that the germination medium is permanently humid, particularly when heat sources are used in order to obtain a higher temperature and therefore a better germination index, the heat will cause faster drying. of the substrate, something to keep in mind in order to avoid unpleasant surprises. In the case of hydroponic cultivation it will always be preferable to germinate in rock wool cubes, which of course must remain permanently humid.
Germinating seeds for too long
Another common mistake, in this case of germination in baking paper or something similar, will be to let the seed germinate until the cotyledons appear. If this is the case, repotting will be very difficult, and it will be very likely that the root will be damaged during this stage. Also, too much exposure to air and light will damage the root, so it’s best to repot before this happens.
In order to avoid any problems, the best will be to plant the seeds when the radicle of these will measure approximately 1cm, 2 at the most. It will be much easier for us to plant and will not harm the development of the roots, which will be able to spread without delay in the new culture medium.
Germinate directly in the ground or in a pot
This is a common mistake that will result in zero germination, especially if there was no watering before setting the seed, or it was done later. By burying the seed directly in the substrate, we will take the risk that it remains buried too deeply, especially if we water the growing medium after putting the seed to germinate.
We will obtain much better results by placing the seeds in kitchen paper, jiffis or in cubes used especially for rooting the cuttings, and transplanting them into the ground or pot once the small seedlings are born. Also, in this way, we will be able to germinate a large number of seeds in a very small space, such as a mini greenhouse, with which we will have a much easier time providing the correct temperature and humidity.
Temperature and humidity for germination
Cannabis seeds germinate well with relatively high temperature and humidity values. It will be necessary, especially during certain times of the year, to use a heat source in order to obtain a temperature of around 26-28ºC. For this, there are several options on the market, such as thermal cables or mini greenhouses, heated. The latter are particularly interesting because they provide a high level of humidity, and they are ideal for the germination of seeds.
The ideal will be to maintain the germination medium at around 26-28ºC and at 70% humidity. Lower values will result in slower and less successful germination, while higher values may cause fungus or mold problems.
Planting the seed incorrectly
If you look closely at a cannabis seed, you will see that it has a slightly oval shape, ending in a point at one end and forming a small “crater” at the other, which is called corona (crown). When planting your seed (whether it’s a seed you want to germinate, for example, in a jiffi, or whether it’s a seed germinated in kitchen paper) you will need to keep in mind that this crown should always be placed facing up.
Thus, you will need to plant the seed with the tip down and the crown up, facing you. Once the seed germinates, the crown will act as a hinge, as the seed will open at the tip end and let the radicle stick out. If the seed has been placed incorrectly, the radicle (root) will grow upwards and the seedling downwards, something to be avoided at all costs because the seedling is likely to fail to grow.
Depth to bury the seed
Often the seed buries itself too deeply (a problem we have already seen in the case where the watering is carried out after planting the seed), so the seedling will not be able to emerge. Otherwise, that is, if we bury the seed too close to the surface, it may be that the germination faces well but the stem grows weakly, bending, not allowing a good development of the little one. plant.
To avoid this kind of problem, it is best to bury the seed about 2cm deep. Also, as the seedling grows, we can bury the lower half of the stem so that it gains stability and produces new roots along the part of the stem we buried. In this way we will obtain an acceleration of the growth of the plants.
Plant several seeds in the same pot
Although it may be tempting, germinating multiple seeds in one container may not work well. In addition to the difficulty of planting the different seeds correctly in the same pot, once germinated they will compete for the little space available for their roots. Cannabis, which does not like having restricted root growth, will grow more airy and with greater internodal distance.
The scarcity of space between plants will also cause competition for available light, something not very advisable if we want maximum yield from each plant. Plants will produce few lateral branches, and will concentrate their growth on a weak main stem with too long an internodal distance, which will affect the final flower production.
We hope this article will help you avoid problems when germinating your seeds, it is very frustrating to start a crop with a lot of illusions and end up with problems before you even start! Do not hesitate to leave us your comments and questions, we will be happy to answer them.
