In commercial marijuana production, producers will often sow many seeds of a single strain and select the best plant.
How to Germinate Cannabis Seeds Fast & Reliably
Like any early stage in the cultivation of marijuana, carrying out a good germination is decisive in obtaining shoots that develop rapidly and obtain powerful seedlings.
In this guide, we will discuss how to germinate your seeds so they sprout in good condition, and how to treat them when they do.
Before you start, make sure you have your growing environment ready and time available to spend. Once the growing process begins, the plant will not wait for you.
Introduction To The Cannabis Seed
If you germinate a seed the right way, it will swell until it breaks the shell. The first thing you will see sprouting is a small white dot called a radicle. This is where the root of your marijuana plant will develop, and will be responsible for absorbing water.
The radicle will grow and push the seed up. Next, the first “leaves” called cotyledons will sprout, and these will finish breaking the seed until it can fully open. At this point, you should already have the plant in a medium where it can grow.
Next, the first characteristic marijuana leaves will emerge — the cotyledons are not really leaves, and they eventually dry out and fall off — as the root begins to develop.
Congratulations! Your plant has been formed correctly.
How Do I Know if a Seed is Healthy?
It is possible to germinate marijuana seeds found in a joint you got on the street. But the best way to ensure you have healthy seeds is to buy them from banks with a good reputation and history, and choose varieties of marijuana seeds for the type of crop you desire.
In general, any seed that is dark and does not break easily is a healthy seed that will germinate well. If the seed is white or pale green, it is likely that it will not germinate.
Obviously, it is always better to do the test before deciding to discard it: If a plant is born, it was a healthy seed.
How Do I Know If It’s Female or Male?
There is no physical difference. If you don’t know where the seed came from, it will be impossible to know the gender of the plant.
You will have to wait for the plant to grow and begin its flowering stage to know if it is male or female.
To ensure that the plant will be female, you can buy feminized seeds from a bank. If you don’t want to buy online, you can get seeds from a growshop in your city, which resell seeds from these same banks. In countries where legalization is more complicated, you will need to resort to donations. You can search for phone numbers for cannabis organizations or try Facebook groups.
I also wrote a guide about types of seeds.
What Does A Seed Need To Germinate?
– Moisture is the first thing the seed needs to activate; the radicle will break the shell in search of more moisture.
– Heat (just enough), the ideal temperature is between 70ºF to 75ºF (21ºC to 24ºC), which emulate spring conditions.
– Leave it alone while you wait for the radicle to appear.
– Be careful when you touch or move it. It is very fragile and can break.
– Oxygen is necessary for the plant to be able to breathe, not to be flooded with water.
– Darkness is not totally necessary, but it is good for the radicle to not have direct light.
Overall, humidity and temperature are the most important factors for a healthy plant.
Water is essential for seeds. You must always keep the germination medium moist — without flooding. If the plant dries out after activating, it will die. On the other hand, if you drown it, the plant won’t be able to breathe properly.
The plant will germinate better if you keep it warm. You can put a “normal” bulb close to it to give it heat — but remember that the root should not receive light. Even better, put the germination medium on top of the power supply of your Play, Xbox, laptop or the like you have. I do not recommend using 3DS, PS Vita or Nintendo Switch
The plant can develop in as quickly as 12 hours, or it can take up to two or four days. If more time passes, it will not germinate. In any case, do not underestimate the speed of seed growth. Have your growing environment ready and check the seeds a few times a day — without fiddling with them.
Marijuana Germination Methods
There are several methods to germinate seeds that are very simple and work perfectly. In the following section we will examine three of the most popular:
Activate them in Water
Letting the seeds soak in water overnight is one of the most widely-used methods by marijuana growers. Simply fill a glass with lukewarm water — between 70ºF to 75ºF (21ºC and 24ºC) — and drop the seeds inside.
Let them rest quietly until they open and the radicle comes out, at which time you will take them out of the water, taking care not to touch the radicle with your fingers, and plant them.
Some seeds take longer to sprout than others, but after 24 hours they could drown. If time passes and the seed has not sprouted, I advise you to transfer it to another germination medium and leave it near a heat source.
The following video on germinating with peat tablets (which I explain in the next section) explains the process of activating seeds by submerging them in water.
The most popular method, and the one I use most frequently, is to allow your seeds to sprout on kitchen paper:
- Put several layers of paper on a plate or a Tupper,
- Dampen the entire paper with a sprayer,
- Important! Drain the excess water in case there is too much; you do not want water to accumulate on the plate,
- Deposit the seeds on the paper, leaving a few centimeters of separation between them,
- Cover them with several other layers of paper and moisten again, and
- Cover them with another plate or lid and secure them so they don’t separate.
When everything is complete, place it on a warm surface. A good trick is to deposit it on a power supply like that of a laptop or a PlayStation as mentioned above. It should not be something that will be moving in the coming days.
If you can’t find a power supply, you can heat the paper up by bringing it “normal” lamps, and putting them on top of the refrigerator or anything that emits a little heat.
Now is the time to leave the seeds alone for a few days. Separate the papers only a few times a day to make sure you keep the paper damp, and to monitor when they begin to sprout.
Once the root has emerged from the seed and is beginning to open, it is time to transplant it into the growth medium.
Dehydrated Peat Pellets
If you don’t like crafts, one of the best methods is to use peat pellets or “germination pills” — they can be bought in nurseries, grow shops, etc.
Peat pellets are specific to start seeds of all kinds; they are very easy to use and will give the seeds the perfect condition to germinate.
- Activate the seeds by immersing them in water, which can be beneficial for using peat tablets,
- Once activated, the tablets are immersed in water — in a different container — to hydrate them for about five minutes so they take shape,
- Then make a hole in the pill and bury the seed, taking care that the root is down and the top is not buried more than 5 millimeters.
Transplanting Marijuana Sprouts To Soil Once Germinated
If you germinated on kitchen paper or a similar method, or activated the seeds in water, it is time to transplant them into a growth medium once the radicle expands. They are still very delicate, so this transplant should not be the only one, but the first.
Small pots or disposable plastic cups are a good option for growing the sprouts. I don’t recommend that you plant the seeds directly into soil or a pot because it will be more difficult to maintain the conditions you need to finish the process properly. A small medium will help you to regulate humidity and temperature.
You will need to get a good substrate, airy and loose. If you use soil from your garden, which is not the best medium, make sure that it does not form mud when it is wet and that it does not remain hard when it has dried either.
Transplanting Step by Step
- Fill your pots or cups with substrate.
- It is important to make holes in the cups for excess water to drain,
- Moisten the substrate without soaking it. Using a sprayer makes things easier,
- Make a hole in the substrate with a pencil or pen deep enough for the radicle to enter completely, but for the top to be barely buried at about 5mm,
- To transfer the sprout, take it gently and insert it into the hole with the radicle down,
- Cover the hole gently with a little soil so it can come out smoothly, and
- Moisten the top of the soil a little.
When planting the seed/sprout, try to use small tweezers so you don’t have to touch them with your hands. If you don’t have any, be very careful when handling it and do not touch the radicle with your fingers.
If you germinated the seeds in peat tablets, you can transplant the whole tablet into the glass or small pot. As for humidity, the same rules apply, moisten without soaking.
Make sure the substrate is always wet as time passes. The top will dry quickly, so stay alert and keep it moist, but be careful not to water it if it’s still wet.
Light: Now It’s Time!
This is when you must give them light. When the plants are outside, they open their cotyledons quickly to make way for their first leaves. Or you can put them indoors if you are growing that way.
If you are growing your plants outdoors, make sure the sun is not too strong; if the pot or glass heats up too much, the plants will burn. Put them where they receive sun indirectly, in a window, for example.
It may take a few hours or a few days, but in a short time the seedling will come out of the substrate looking for light. If after ten days it still has not left, it is likely that it will never do so.
Before moving to the final growth medium, wait until the seedlings are stable and have at least 4 leaves so that they can withstand the last transplant without too much stress.
The good thing about plastic cups is that you can cut them out, which makes it easier to transplant.
Common Germinating Mistakes You Should Avoid
Looking at them too much
Constantly uncovering the seeds to see how they’re coming along can stop the whole germinating process. You must be patient with marijuana and let nature do its work in peace.
If the growing environment is not warm, the seed will know that it’s not the right time to sprout. As mentioned above, the ideal temperature for the seed to grow is between 70ºF and 75ºF (21ºC and 24ºC).
Touching them with your Hands
Putting your finger in the radicle can cost you the crop. It is very fragile and easily separates from the seed. Always grab it by the part of the shell or, failing that, the cotyledons, and always do it delicately.
Too few water
I never tire of mentioning that marijuana seeds must be in a humid and moist environment 24 hours a day for it to grow. If you let the environment dry, the seed will die.
Too much water
Once the seed is open, it needs oxygen to live – if you don’t let it breathe it will die. If you use a water sprayer it will be easier for you to avoid going overboard. You should also always make sure to drain the excess.
Hard pipe water
Some cities have water that is loaded with salt or lime. In these cases, it’s better to use bottled water (and if you plan to irrigate your crop with this water you should find ways to clean it as it will also affect the growth of the plant).
The plant does not need fertilizers or stimulants during its first weeks of life. Compost soil could burn it. So, a quality growing soil will be necessary.
Planting them too deep
The seed must be buried deep enough so that it is barely covered and can easily break through. The ideal height is about five millimeters.
Using Moisture Domes?
According to the Mandala Seeds bank, it is not recommended to prevent ventilation using domes because it can quickly cause fungi in the germination medium.
On the other hand, Sensi Seeds bank does recommend them but you should take care not to use them for a long time. It also mentions the importance of ventilation.
Thank you for reading
Any of the methods listed in this guide will achieve a germination percentage close to 100%. But remember, there will always be seeds that do not germinate; even the most prestigious banks cannot guarantee that all their seeds will sprout.
The interesting thing is that although some will be unsuccessful and others may take longer, some will open quickly and grow strong. This will tell you from the beginning which are the most vigorous plants, and they are probably the ones you will choose if you want to have mother plants to make clones or your own seeds.
Now that you know how to germinate and transplant the seedlings, the next thing to study is how to take care of your plants in their first weeks of life. Everything has to do with the growing environment you have prepared before starting to germinate, or you will not have enough time to treat your seedlings properly.
In a short time, I will write guides on preparing your growing environment — whether you are going to grow outdoors or indoors — and on the treatments for the first week of vegetative growth. If you want to be alerted when they’re published, sign up for my mailing list below.
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.
PSYCHO XXL AUTOMIX
Here are 3 practical tips to protect the health of the seeds to be germinated (where cannabis home cultivation is allowed).
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.

A Simple Guide To Germinating Cannabis Seeds
You can grow your cannabis from either a seed or a clone. In commercial marijuana production, producers will often sow many seeds of a single strain and select the best plant. During the cannabis grow stages, producers will take clones of that particular plant, allowing for uniform genetics in large production.
Since marijuana is legal in your state, you can purchase seeds or clones from the local dispensary or several seed banks online.
When is the Ideal Time of Year to Start Growing Marijuana Seeds?
The beginning of spring is the optimal time to germinate cannabis seeds for outdoor growing. Cannabis plants are annuals, meaning they will grow throughout the spring and summer before flowering in the Autumn as the days become shorter. If you’re growing your seeds inside, you can germinate them whenever you want as long as you provide them with the necessary atmosphere.
Duration Taken in Cannabis Seeds Germination
Sprouting can take anything from a few days to a week for your seeds to begin to sprout and grow into plants.
Will Seeds Germinate in a Paper Towel When Placed in The Dark?
Yes, to put it briefly, a seed will often sprout with a bit of moisture, warmth, and darkness.
A substance called phytochrome is the key to this. In light, phytochrome exists in one form, and after a time of darkness, it exists in a different form. After a few HOURS, the light form decreases to a dark state; after several MINUTES in the light, it is converted back. As a result, a seed on the soil’s surface receives enough light to maintain the dark state of phytochrome low for long enough to prevent germination. The dark version of phytochrome is only active long enough to cause germination when the seed is in complete darkness.
The tissue will help keep your sprouts moist, but it will not provide additional nutrients. They’ll have enough food to get started from seed, but they’ll require soil or food for happy roots and light to create strong green leaves.
Remember to distinguish between what a seed requires and what your seedlings require; thus, examining the plant’s requirements after germination is an intelligent idea.
What are the Optimum Temperature and Light Settings in Germination of Cannabis Seeds?
Seeds require appropriate warmth, humidity, and air to sprout efficiently. Marijuana seeds like a temperature range of 70°F to 90°F for sprouting. It’s why cannabis grow tents are dark on the outside to increase temperatures. Seeds do not require light to germinate, but seedlings need good lighting to grow.
Why Won’t My Cannabis Seeds Sprout?
When growing cannabis from seeds, seeds may fail to sprout because of various causes, including age or dryness, improper storage, incorrect cannabis germination methods, and difficulties at the seed bank.
I do not recommend disturbing or attempting to shatter the seeds at this time because they are very fragile and could be damaged. To “activate” your seed, use the “glass of water” procedure. It’s best to wait for now and be patient, ensuring they have the best sprouting conditions.
How Deep Should I Plant My Cannabis Seeds?
Direct planting is even more natural than soaking in water. Sow your seeds 1/2 inch to one inch deep in damp soil or a similar medium. Not subjecting your seedlings to transplant shock is a significant advantage of this method. They will have adjusted to their surroundings because they have grown up in them.
When you want to germinate cannabis seeds, patience is essential, and this step is no exception. Taking notes is a great way to keep track of your progress and figure out what’s working and what isn’t. Refrigerate your seeds until you’re ready to start. It takes a little research and experimentation to grow cannabis, but it’s not rocket science, and it’s a VERY satisfying experience.
