The most common mistakes when germinating cannabis seeds

Germinating the seed is the first step in any cannabis grow. It is the process during which the seed begins to develop, and the radicle emerges. There are several methods of germination and there are a number of common mistakes made in each of them, which can be easily avoided.

Here we explain what not to do during germination in each case, and we tell you that the method recommended by Dinafem Seeds is germination in Jiffy, as it is the simplest and has the lowest error rate.

Mistakes when germinating cannabis seeds in Jiffy

Jiffies are dehydrated peat discs, pressed into a biodegradable mesh which, when moistened, become tiny sacks of earth. Water is usually applied so that the wet discs swell and become mini containers of substrate where you can plant the cannabis seed so that it germinates inside the peat. What could go wrong with this method so that we don’t get to see the seedling emerging from the Jiffy?

  1. Adding too much water to the Jiffy: the disc must be moistened so that it swells, but it should not be drowned. The goal is to keep the soil in the Jiffy moist during the germination process, but never drowned. Some growers water the Jiffy too much, and more often than necessary, and end up drowning the seed because excessive moisture prevents the ventilation of the seed, stopping its germination.
  2. Covering the Jiffy so that it is too hermetically sealed: the Jiffy has to be protected, but some people shut it away in a germination greenhouse or Tupperware container with holes, increasing the moisture excessively, which leads to the growth of fungi.
  3. Burying the seed too deep: The seed should be about one centimetre from the surface. Although it is true that the depth of a Jiffy is not more than 10 centimetres, pushing the seed to the bottom of the Jiffy will make it difficult for the radicle to find its way out into the light. Just insert the seed with your finger, near the surface, and cover the tiny hole made when you insert it.
  4. Not providing it with the right light intensity: in the first germination stage, when the radicle begins to rise up, it is better to provide too much light rather than not enough, because light does not bother cannabis. Of course, in the case of the Jiffy, we must keep in mind that the light, whether from the sun or a spotlight, is linked to the possibility of drying out. So, even if it is good that the Jiffy has plenty of light, we have to make sure that this is not drying the soil too much.
  5. Subjecting the Jiffy to changing temperatures: changing the temperature for example from 25 degrees (indoors) to 5 degrees (on a terrace) will make germination impossible.
  6. Putting several seeds in the same Jiffy: these peat pellets are not big enough for several seeds. We should use one for each seed we want to germinate.
  7. Keeping the seed in the Jiffy for too long. As soon as the seedling has a pair of cotyledons, it must be transferred to the substrate. The Jiffy is small and can only be used for so long before space must be given to the roots to grow in the pot or in the soil.

Mistakes when germinating cannabis seeds in damp cotton wool or paper

The method of germination in damp cotton wool or paper consists of moistening these materials and wrapping the seeds in them. In this case, it is advisable to put these wet fabrics in a germination greenhouse or Tupperware container with holes for ventilation, so that the temperature remains the same throughout the process. So where could we go wrong in this case?

  1. Letting the radicle grow too much: if the root becomes too long, it will probably end up getting caught up in the cotton wool or paper and will then break when detached from them before being transferred to the substrate. To avoid this, we need to do two things. First, don’t let the root get too long. As can be seen in the photos, the radicle grows very fast, so we have to put it in the soil when we see that it has grown in a certain direction (we can see that it either grows in a straight line or it adopts a more curved shape). Second, do not use pure cotton wool or kitchen paper, but rather cotton fabrics such as rags or pieces of old T-shirts.
  2. Exposing the seeds to changing temperatures: if we keep exposing them to different temperatures, seeds will not germinate. We must ensure that the place where we put them is warm, between 25 and 28 degrees Celsius, and that this temperature is kept stable until we transplant them to the substrate.
  3. Leaving the root in contact with the air for too long: left in contact with the air the root will oxidise, which will in turn kill the plant. When the root begins to grow, it is best to transfer it to the substrate immediately. Or, failing that, keep it well covered with the wet fabric.

Mistakes when germinating cannabis seeds in substrate (in a pot or in the ground)

Planting the seed directly into the pot or the ground where we plan to grow is another option for germinating the seed. Let’s have a look at what is usually done wrong in this case, leading to the cannabis seeds failing to germinate.

  1. Burying the seed too deep: the seed should be one centimetre below the surface and not any deeper. As a general rule for seed germination and cultivation, it is recommended to plant the seed at a depth equal to twice the size of its diameter. It is enough to cover the cannabis seeds, which are small in diameter, with just a little soil.
  2. Over-fertilising the substrate: the soil where the seed will germinate should be porous and light in nutrients. The substrate used for a flowering plant is not the best choice to germinate a seed, because a marijuana ‘baby’ cannot assimilate the same amount of food as an adult marijuana plant. So, let’s be sparing with the diet in the soil where we have placed the seed to be ‘born’.
  3. Using a soil with an unknown composition: the soil from the park near our house, or from the vegetable garden of the house in the village are not the best options for germination. It is important to know the composition of the substrate where we are going to plant the seed. And when we take soil from somewhere else, it may contain many minerals, or many nutrients, or a lot of fertiliser, and if we have not bought it in a bag where its ingredients are listed, we will not know its composition. So, it is important to use a substrate whose composition we know, especially for this first step in growing.
  4. Watering too much: a substrate that is too wet, especially in the case of autoflowering seeds, can be lethal for germination, and for the seedling’s first few weeks of life.
  5. Putting several seeds in the same pot: unless it is a very large pot, let’s give each seed its individual space so that the roots have enough room to develop. If we put several seeds in a 14-litre pot, for instance, some seeds may end up hindering the development of the others.
  6. Planting the seed directly in the ground where the climate is not appropriate: if the weather is too cold, too hot, too dry, or too wet it will be difficult for the seed to germinate. Since we do not control the environmental conditions in an outdoor substrate, changing weather conditions can easily hinder the germination of the cannabis seed.

Mistakes when germinating cannabis seeds in water

This method consists of putting the seed in a container with warm water and waiting for it to germinate in the days following immersion.

  1. Leaving the seed in the water for too long: as soon as it has germinated, and we see that the radicle has emerged, the seed must be transferred to the substrate. Water can be used to germinate it, but never to grow it. So, as soon as we have achieved the goal of placing it in the liquid, we have to take it out of there and provide it with the substrate it needs to survive.
  2. Overdoing the dosage of hydrogen peroxide in the water: if you want to include hydrogen peroxide to prevent fungi or bacteria during germination, you have to pay attention to the concentration. Overdoing the amount can prevent germination.

Common mistakes of any germination method

  1. Breaking the radicle while trying to separate the shell from the bulb. Being very invasive in the germination process can be lethal to the seed. Once it has germinated, the seedling will generally eject the seed shell itself, so we should leave the seed to do its job. We recommend intervening only if it is really necessary, and we see that the plant is growing upwards and that the shell is still attached to some of its parts.
  2. Handling the seeds, radicles or seedlings with dirty hands. We don’t know what type of dirt we might be carrying on our hands without realising it, so we should always wash our hands before carrying out any of the germination processes. This hygiene also applies to each of the tools that are in contact with the seed during the germination period.
  3. Using dirty water. It is important to use clean tap water at all times.

What to do if your cannabis seeds do not germinate: 3 practical tips

Cannabis seeds are real living organisms and as such are susceptible to many environmental factors, such as light, humidity and temperature. If you’re wondering what to do if the seeds don’t germinate, maybe you need to freshen up on what European law says about it.

The sale and possession of seeds are legal in our country, as they do not contain any trace of THC. However, if the weed seeds germinate, they would give birth to a plant capable of producing inflorescences with a high rate of tetrahydrocannabinol, turning your culture into an administrative offence.

The marijuana seeds that you can buy online in shops like Sensory Seeds are purely collector’s items and can be used for purposes that do not involve germination, such as collecting. However, in other countries, the cultivation of hemp seeds is legal for personal use, such as in some cities in Spain.

1) Which seeds do not germinate? Here is how you can recognise them before it is too late

There are many reasons why marijuana seeds do not germinate, and it is not always easy to recognise the cause. However, there are signs that you may be able to identify those specimens that are likely to cause problems. Improper storage is one of them and can be the cause of your seeds not germinating because they are already dead.

It can happen if you have bought your cannabis seeds from unreliable sites that sell off old items as discounted products. Seeds that do not germinate may have changed colour and become significantly darker or have a white patina on the rounded end; moreover, if you open the seed, you will notice that the embryo has become soft.

For this reason, we recommend that you always check the health of the seeds as soon as they come into your hands, mainly if you are used to buying your weed seeds online. In this case, you should only turn to reliable shops like Sensory Seeds, which guarantee the health of the products in your shop window.

2) Do you want to try to germinate an old seed? Here’s what you can do

If you have an old marijuana seed in your hands or you have tried to plant it, and nothing at all has happened, you can try to make a desperate attempt to resolve the situation. There are 4 ways you could proceed, and they are as follows:

  • Soak the seeds with enhanced water
  • Seed shell rubbing (scarification)
  • Cut the joint that closes the seed
  • Dissect the seed

The first attempt to do among these is undoubtedly to soak the unsprouted cannabis seeds in a container with sparkling water or, better still, enriched with fulvic acid or growing booster. Keep the solution at a temperature of 20°-22° and away from light for 12 hours: in this way you may be able to get moisture into the dehydrated shell and give the embryo the starting input, but be careful not to exceed 24 hours of soaking.

If after this attempt the seed does not show signs of life, you can move on to scarifying the shell, i.e. its abrasion to create grooves that facilitate the passage of moisture to the embryo. Insert sandpaper into a container, tape it up and put the cannabis seeds in it: after closing the lid, shake the container for a minute or two and then try again to soak the seeds in water for a few hours.

Still nothing? Take a knife with a smooth, sharp blade and slide it along the kerb of the two halves of the seed shell until it is removed: a very thick shell can make it difficult to open the seed to get the rootlet out. If the first 3 attempts are unsuccessful, dry the seed, cut the shell with a sterile scalpel along the groove under the shell and try to germinate it.

If you haven’t managed to win the battle in this way either, you will, unfortunately, have to feed the seeds to your budgies…

3) All you have to do not cause the cannabis seeds to fail to germinate yourself

There are many causes for a hemp seed not to germinate, including fungal infection. This type of mould can attack your seeds in the following cases:

  • Poor quality soil
  • Excess humidity
  • Too much watering
  • PH inappropriate
  • Poor ventilation
  • Temperatures too low

The guidelines for storing seeds before planting are stringent:

  • The temperature of 6°- 8° C
  • Humidity between 20% and 30%
  • Keeping in the dark
  • Avoid oxygenation
  • Maintain the stability of the previous parameters

If you clumsily follow these directions, you might run into the problem we’ve been talking about. Besides, if the extreme methods of achieving germination have not been successful, you may find that the embryo is infected with liquid-looking, yellowish fungi.

Other problems can arise from using chlorine-laden tap water (it is best to let it evaporate 24 hours before use) or from breaking the semen shell due to pressure, which you should always be very careful of.

Final considerations on unsprouted marijuana seeds

Poor germination is not always your fault, as there may be external factors that make it difficult or sometimes impossible. In some cases, the soil used may have been a fungus carrier or its type was not the right one; other times the fault is due to a malfunctioning or poorly calibrated conductivity meter.

Falling into a failure to germinate is sometimes almost inevitable: in some unlikely circumstances, you may have done nothing wrong, but your seeds will still not germinate.

To make a summary, cannabis seeds that do not germinate may be defective due to external causes or inadequate storage. If the seeds do not germinate immediately, you can try using the techniques we have mentioned in this article and hope that they work.

Why Are Your Cannabis Seeds Not Germinating?

Many first-time growers and inexperienced planters often experience this problem when trying to cultivate cannabis seed. They end up languishing and wondering why their effort is not yielding since a cannabis seed has a pretty high germination rate (99%). However, many things might not promote the germination process.

Generally, cannabis seeds are powerful and grow pretty fast. If the seeds do not germinate, there is likely a problem with the germination method. This article will explore many things that can go wrong when trying to cultivate cannabis seeds.

Genetics

The chances of having a viable seed increase significantly if the genetics is good. This is pretty important as it can avoid wasting energy and effort trying to germinate a bad seed. When you buy good quality seeds from trusted banks, you can breathe a sigh of relief, knowing that your actions will not be wasted.

As a result, it is not a good idea to grow seeds that you stumbled on inside a cannabis bag you got. Such seeds could be infertile and may not germinate. If it eventually germinates, you might not like cannabis. Make sure to buy the right seed from reputable stores and increase the chances of germination.

Direct Soil Germination

This is one of the top reasons your cannabis seed is not germinating. If you do not water the substrate before sowing the seeds and water afterward, there is a high probability that the seeds will not grow. This is not surprising as the seeds could be buried too deep, and adding water after sowing worsens this.

You can obtain good results by germinating the seeds in jiffy pellets, peat plugs, or using kitchen paper and later transplant them to a pot or the soil when the small seedlings come out. Make sure to care for your tender plant at this stage. Limit irrigation, support the right temperature and use Northern lights when growing indoors.

Wrong Temperature and Humidity

The ideal temperature for germinating cannabis seeds is high humidity and high-temperature levels. It is essential for people in tropical countries to provide external support of heat to get the temperature within reasonable and acceptable ranges. This is where heated greenhouses come in. Not only do they provide the right temperature, but they can get the humidity level to the ideal range essential for germinations. A cannabis seed needs 70% relative humidity and an average temperature of about 270C for germination.

If the temperature and relative humidity ranges are lower than the ideal value specified, the growth rate will be slow and unsuccessful. Excessive range, on the other hand, can lead to fungal problems.

Seeds Planted too Deep.

The amount of energy available to a germinating cannabis seed is limited. As a result, if planted too deep, it might not have the required energy to make its way up. A seed planted underground will have no light and is not producing food yet since no photosynthesis. Planting seed too deep creates extra stress for the seedling as migration to the surface becomes an issue.

As a result, you should plant your cannabis seed around 2 to 3 cm down or half inches deep. With this, they have enough room to grow taproots. This might be one of the reasons your cannabis seed didn’t grow.

Using Old or Unsterilized Pots and Soils

A fungus is one of the greatest enemies that might affect the germination of cannabis seed. If you reuse soil and it is not sterilized, there is a high chance of mold and other unhealthy organisms like insects and bacteria. As a result, the seeds may not sprout at all. Even if they grow, these organisms might kill them after a couple of days. For instance, a sprouting seedling might suddenly bend and change color to brown in a process known as damping off. This is common when you supply the seed with too much water when there is poor drainage or the aeration is poor.

Due to this, consider planting seedlings in a sterilized pot as the tendency of containing harmful organisms is low. Also, make sure the containers are clean as it can reduce the tendency of fungus.

Planting lots of Seed in one Pot

Planting a lot of seed in a single container might seem like a good idea due to the ability to save cost. This is like shooting yourself in the leg, as it might lead to a wasted effort. Even if the seeds germinate, they will compete for limited space, nutrients, and water. A cannabis plant needs enough space for its root to travel down without restriction to prevent severe intermodal distance.

Limited space translates to severe competition not only for nutrients but light as well. This is not a good idea if you want to get the best from your cannabis seed. If the seed eventually germinates, they will be weak, which will affect the plants and overall output.

Cannabis Seed left underwater for a long time.

Some growers prefer to soak their cannabis seeds before planting them. This is an essential step to break the dormancy and soften the shell to prepare the seed for planting. With a softshell, the taproot will easily break the body and push its way out of the shell. Typically, the seed will be put inside a glass of water and left until it sinks before the grower plants it. However, this is not as simple as it sounds.

A cannabis seed needs to be continually breathing, and a fully submerged seed will not get the necessary air supply. This might kill the seed if left for long inside the water. Once the seed sinks, take them inside the paper towel as soon as possible.

Conclusion

There are many intricacies involved in germinating a cannabis seed. Getting it wrong with any of the systems might not make the cannabis seed grow. You can arm yourself with these essential tips to ensure that your cannabis plants germinate. Use these tips as a guide when trying to germinate your cannabis seed.
