Germination of cannabis seeds is a relatively simple process and does not require a sublimate of hassle. But that is not to say that we should not carry there rigorous follow -up. By respecting the important factors for good germination, a high germination rate is obtained and the risks of surprising a fungal infection are reduced. 

Unfortunately, for lack of information, some people make serious mistakes during the germination process, which are sometimes lethal of the seeds. As a potential cultivator of cannabis seeds, you surely don't want to get there. Discover with us the behaviors harmful to the development of your cannabis seeds and at the same time, get some tips to avoid them.

Excessive or non -existent watering

The most common seed germination problems are linked to the amount of water (and the germination technique) used in cannabis plants. Many problems of germination of seeds of cannabis are caused when the seeds are too watered and soaked or vice versa. 

What characterizes excessive watering of cannabis seeds?

Soak the seeds, or give them an environment with too much water, causes their stagnation and stops their growth. When a cannabis seed germ, a small white root emerges. This is a seed of Sativa cannabis or Cannabis Indica. However, if the cannabis seed is soaked too long, the root will stop growing and will eventually rot. 

An indication of root rot is a brown coloring on the root or the end of the root. Cannabis roots need oxygen and humidity to produce the Cannabis leaf. But if these roots are soaked for too long, there is not enough oxygen for their health to be maintained and the rot will therefore begin. 

What characterizes an insufficient watering of cannabis grains?

Conversely, seed germination problems are also observed when the cannabis seeds dry up due to insufficient humidity. This can happen when producers try to germinate their seeds between damp cottons, but forget to put them in a sealed container. For example, it can be a plate sealed with a transparent kitchen film. 

Without humidity, the cannabis root dries up and simply dies. When the seed begins to germinate, you will notice that the swivel root is covered with many delicate radicular hairs. These dry out and die unless the root is preserved in wet conditions (but never soaked). Just like with a too watered seed, once the root shows discoloration and dies, it is often damaged beyond any repair.

How much water should we use for successful germination?

The watering aims to keep the soil moist and prevent it from drying out. As a result, the small root of cannabis will have to absorb very little water at the start. If you germinate your cannabis seeds between slightly sprayed cottons, the buffers only need 5 short sprays to moisten them. 

Remember that the key principle is to provide a healthy environment with humidity and a little air. If you try to germinate your cannabis seeds In an environment saturated with water for too long, the roots simply rot.

Germination of cannabis seeds outside

Many people like to germinate the seeds of cannabis Outside, especially outdoor/greenhouse growers. Why not ? This is how the seeds have evolved over the millions of years to germinate. However, it should be noted that in nature, a plant can produce hundreds/thousands of seeds, but only needs a few to overcome germination so that the next generation survives. 

Cannabis producers, on the other hand, like to see germination rates of 90 to 100 %, especially if they bought First quality cannabis seeds For their specific needs. Unfortunately, these producers may find it difficult to achieve good germination rates if they are counting on the germination of outdoor seeds. The best thing is to buy specially outdoor cannabis seeds. The reason is that the conditions can fluctuate considerably, in particular during unpredictable meteorological upheavals and affect the seeds of cannabis unsuitable.

What consequences on your seeds?

Temperatures and/or weather conditions can significantly oscillate between night and day, reducing germination rates and killing lower sowing.

  • If the weather is cold and humid with persistent rain, the seeds can simply rot in the soil and never emerge. Even if your cannabis seeds manage to develop, slugs (snails, birds), can reach sowing before you. 

  • If the start of the season time produces a heat wave, your seeds can dry if the roots have not been able to reach humidity enough. 

Germination of cannabis seeds Outside can work for certain seeds, but it is not recommended to obtain very high germination rates. Those who germinate cannabis seeds outside in containers may find that the containers receive very hot indirect light. 

Temperatures around (or superior) to 35 ° C/95 ° F can kill seeds by excessive heat. This is why many outdoor cannabis producers who succeed prefer to germinate the cannabis seeds inside. There, the conditions are more favorable to minimize the problems of seed germination.

What is the best temperature to germinate cannabis seeds?

The temperatures found in an average house, from 20 ° C to 25 ° C, are perfect for germination of seeds of cannabis. They are also ideal if the finality is to make it Therapeutic cannabis

Many serious outdoor cultivators end up opting for the germination of seeds inside to maximize germination rates. One of the many tips mentioned by outdoor growers is to push their sowing inside in artificial light for a few weeks to give them the best possible start before risking them outdoors. It is the best way to avoid problems of seed germination and to ensure that a maximum number of your cannabis seeds precious will make healthy adult plants.

Overheating sowing with heated carpets

For good germination rates of cannabis seeds, you need both humidity and heat. The seeds that could germinate at room temperature inside in summer may not germinate so easily in winter in a cold part of your home. Sometimes, during the coolest months, the interior temperature may require a little help. 

This is why many producers use a plug -in electric heating carpet. This can be set to a specific temperature to provide the heat necessary to bypass seed germination problems. For their part, the pots of plants, or propagators, simply rest on the heating carpet. They can be an excellent solution for cold periods in winter. However, cases are encountered where heated carpets are used all year round. 

What consequences for your seeds?

In summer, using heated carpets is not necessary and can cause overheating of plant containers and seeds that will be damaged/destroyed by high temperature.

When interior temperatures are already 20 to 25 ° C, there is no reason to risk adding additional heat, especially if it cannot escape. Danger is overheating of the soil and obtaining sterilized seeds. In combination with excess humidity/excess water, cannabis seeds And the delicate fabrics inside are slowly cooked and destroyed. This can happen if the excess heat of the carpet cannot escape and accumulates in the containers of the factory over time.

Can we use a heated mat for germination?

Yes of course. You can use a heated mat for germination but use it only during colder periods such as winter. Due to the heat that can accumulate in the soil or in a propagator, be sure not to adjust the too high temperature. Temperature settings of around 20 to 25 ° C should ensure a pleasant and hot environment, without risk of overheating. You can also use a thermometer to confirm that temperatures are held in the favorite beach of 20-25 ° C.

Incorrect fertilization of cannabis sowing

When sowing germinate for the first time, they are very sensitive to their growth environment. A strong short -range light easily damage their delicate foliar tissues. Extreme temperatures and large temperature variations/cold nights can also be fatal. However, poor diet will have greater repercussions. This is why you have to take a careful look at the nutrition of your sowing in the first two weeks.

What are the consequences of incorrect sowing fertilization?

A current error observed by experts in the field is an excessive fertilizer diet administered to sowing. Producers of cannabis Often use a wide variety of nutrients/fertilizers to cultivate their plants. Sometimes they make the mistake of adding to abundance during the first stages of growth. In the worst case, this can permanently slow growth or kill the plant. There are two things to know.

  • Sowing and their delicate root systems cannot very well manage an environment rich in nutrients.
  • They naturally acquire during their growth, everything they need for a healthy initial germination and development within the seed itself. 

So when the seeds germinate for the first time, they don't need fertilizers at all.

When should you use nutrients with germinated cannabis seeds?

Many producers prefer not to add fertilizer or additives during the first week of growth. Your sowing will not need it for the moment and will only be damaged if it is exposed to an excess of nutrients or fertilizers. If you cultivate in good quality soil, you may not need to add additional nutrients for a week or two. Even in this case, you should only consider low/start -up nutrients and slowly increase concentrations.

Choice of bad type of soil to germinate the seeds

Use a little earth from their rear garden to germinate cannabis seeds is something that most cultivators do. It is generally a beginner's error or an attempt to save money. But it is really not recommended. Avoid using too sandy soil (or too heavy with a high clay content). Sometimes the soil is quite healthy and the seeds germinate without problem. But in many cases, it is too arenaceous or too heavy with a high composition in clay.

What consequences on your seeds?

The garden floor is not suitable for your seeds. Indeed, it contains:

  • molds;
  • Mushroom ; And 
  • Unnecessary parasites. 

At worst of cases, it can be strongly fertilized. Often, the pile of producer compost is used for sowing. The logic is that it is fresh, natural and perfect for culture. However, the freshly composted soil is very rich in nutrients. Perfect for mature plants, but toxic for sowing, which are delicate and only need light nutrition (if applicable). In other cases where garden soil has been used, you can see mold developing on the ground surface, which gives it white discoloration. Sowing affected by mold may have a high risk of damping and death.

What type of soil should you use to germinate cannabis seeds?

For an optimal result, be sure to use clean and fresh land. This allows you to have cannabis with CBD and THC reasonable. This soil can be found in a gardening center or a culture store. On the other hand, do not use a strongly fertilized soil. Normal soil is often good to use. But for convincing results, we recommend a 50/50 combination of light mixture and coconut substrate. This mixture is very easy to cultivate for roots and contains the ideal proportion of nutrients so that sowing can develop properly. When your sowing lasts 1 to 2 weeks, the roots and the plant may contain more nutrients and a very light power program can be used. Regarding nutrients and young plants, be very careful. It is preferable to nourish plants with low nutrients and gradually increase nutrient concentrations. It is much better than starting with strong nutrients that can potentially damage or kill young plants.

Now that you are aware of the mistakes not to make when germinating a cannabis seed, what are you waiting for to have your first experience?
