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.

How to germinate pot seeds in soil

Germination is the first step in the growth cycle of each plant. This process brings the seed out of its hibernation period and begins the growth process of the plant. All of this begins when the seed receives the necessary environmental conditions and is in the right setting to start growing.

There are several different methods of germination growers use, but today, we’ll focus on one particular method: germinating cannabis seeds in soil.

Advantages and Disadvantages of Germinating Cannabis Seeds in Soil

Starting cannabis seeds in soil is an easy and natural method of germination, as this is where seeds would germinate if they were to grow out in nature. There are several pros and cons to using this method, so let’s check out what those are.

The advantages of germinating marijuana seeds in soil include:

  • Safety.
    In the wild, it’s the soil that protects the germinating seed and its roots from outside interference, offering the seed a safe space where it can grow and develop.
  • Natural method.
    This is the most natural method of germination that occurs out in the wild.
  • No added stress.
    Soil not only provides the perfect medium for the seed to germinate but also to grow, meaning it doesn’t need to be interrupted by transplanting it into a different growth medium, avoiding unnecessary stress.

The disadvantages of germinating weed seeds in soil include:

  • Less control.
    When using other germination mediums such as damp paper towels, you have better control over the process – namely, the ability to monitor and adjust moisture and temperature levels accordingly. You can also watch the root closely as it grows and be able to know when the perfect time is to plant your seed
  • No control over diseases.
    When working with soil, you’re not working with a sterile environment such is the case with paper towels, meaning that your seed could encounter certain diseases and pathogens that might prevent it from sprouting. To avoid these issues, purchase sterile soil rather than using it straight from your garden

What is the Best Soil for Germinating Cannabis Seeds?

When deciding to use soil to germinate your seeds, the first thing you need to do is make sure you get the right type.

The type of soil that would work best has spores and minerals that help when you’re starting cannabis seeds in soil directly. These minerals will be enough for your young marijuana plants to thrive in their first couple of weeks, so you don’t need to add any nutrients during this time.

Here’s what to look for when purchasing soil for germinating cannabis seeds:

Soil Texture

The perfect soil for germinating cannabis seeds needs to be light and airy and have the following or similar ratio of components:

  • 4 parts compost
  • 1 part perlite
  • 1 part vermiculite
  • 2 parts peat moss

You can also go with a pre-made starting mix if you don’t want to make your own.

Soil Nutrients and Amendments

You don’t need to add nutrients and minerals to your soil mix, at least for the first couple of weeks, as the potting soil you use will have enough nutrients to sustain your plant’s life and help it grow during this timeframe.

Soil pH

The potting soil you use should be mildly fertilized, or you can also go with a pre-made seed starter soil mix. No matter which you choose, your soil should have an approximate pH of 6.

How to Germinate Weed Seeds in Soil: Step-by-Step Guide

Now, let’s check out the process of germinating cannabis seeds in soil step by step.

Step 1 – Prepare the Soil

When germinating weed seeds directly in soil, the first thing you need to do is get the right potting soil or seed starter. When it comes to the texture of your starter soil, you can follow our guidelines on the ratio above. Next, place the soil into small pots, depending on how many seeds you’re going to be germinating.

Step 2 – Plant

Use a pencil or stick to poke a small hole in the soil that’s around half an inch (1cm) deep. Plant the seed into the hole and lightly cover it with soil. Once you’ve completed this step, don’t touch the seed or disturb it in any way – just let it position itself and start germinating.

Step 3 – Maintain the Right Grow Conditions

Keep your pots away from direct sunlight, but in a warm area with a temperature range of 70 to 80°F (21-26°C).

Place your pots under a fluorescent lamp and water them gently using a spray bottle. Use distilled water instead of tap water so as not to compromise your seeds with unwanted minerals and substances that can be present in tap water.

Let your seeds germinate, and when their stems reach 2-4 inches (5-10cm) in height, you can start transplanting them into bigger pots.

Pro tip: Use peat moss pots or another type of degradable pot so you can transplant your seeds along with the pot without disturbing their root systems.

Remember, the quality of the seeds you purchase plays a huge role in how successful the germination process will be. If you’re looking for the right seeds to plant, look no further than Herbies. At Herbies, you can find the best viable, vigorous, and fast-growing seeds with high cannabinoid content from seed banks around the globe. All seeds are stored in perfect conditions and are inspected by experts before shipping.

As you can see, the process of germinating cannabis seeds in soil is pretty simple and straightforward. However, for those of you who are still left with a few unanswered questions on this topic, we’ve composed a list of the most commonly asked ones on the subject to help clear things up.

The perfect temperature range for germinating cannabis seeds in soil is 70 to 80°F (21-26°C).

How long does it take for cannabis seeds to sprout from soil?

It can take from two days up to a week for your cannabis seeds to sprout from the soil, depending on their quality, viability, and other factors.

Germinating cannabis seeds in soil vs. peat pellets – which is better?

Peat pellets offer fast results, are easy and convenient to use, and make planting a super easy and fun process. Soil, on the other hand, provides seeds a more suitable medium in some cases, mostly because it’s the most natural method. Soil doesn’t dry out as fast as peat pellets do and it’s more economical, as you can make your soil mix yourself.

Can i put seeds straight into soil?

I was wounder if i could put my seeds straight into soil to germinate and keeping the soil moist and in a dark place?

In my opinion that is the bestway to do it, usually sprout in 3 – 5 days, I prefer straight in the soil compared to the paper towel method. More people prefer the paper towel method but I figure the less you handle the seeds the better your results will be. Plus I’m still under the impression that the less amount of stress you put the plants under the more females you will get.

alright sounds good but how long would it take until u noticed the seed sprouted and did uses use any light while uses done it or just kept it in the dark?

If you plant straight into soil the plant will adjust to any light you have, you don’t need to worry about burning it which is another good thing, you could start it under a cfl or 1000 watter and the plant will be adjusted, no worries there. After you plant I’d just start whatever light cycle you planned on using and the plant will adjust itself.

I use the paper towel method as I like to be able to check the seeds’ germination progress (i’m impatient) but you certainly can.

i use this much light to start the seeds on 18/6

Thats the natural way, yes. I would not put them in the dark however. Have the lights on, it will give the plant something to “reach” for AND it will tell the seed/seedling “time to grow dammit.”

yeh thanks fer the quick replies iam thinking on putting about 5 seeds in jiffy cups and placing them into one pot of soil under a 40w cfl or should i get more light and what light schedule should i use?

If that’s the case I’d get a white 5 gallon bucket and put the jiffy pots in the bottom and get a board to put across the top of the bucket with the cfl inside the bucket and mounted to the board. It will keep the plants warm and the white bucket will reflect the light. Use a 42 watt daylight CFL and you will have great success until the plants out grow the bucket. That’s the best route to go.
