5 common mistakes when germinating cannabis seeds
Although the germination of cannabis seeds is a relatively quick and easy process, it is crucial to take into account a series of important factors in order to obtain as high a germination rate as possible. In addition, it’s in our interest that the seeds germinate as quickly as possible, and especially if we want to avoid problems like fungal infection or a low germination rate.
In our article on how to germinate cannabis seeds we explain step by step what you must do to achieve successful germination. Today we will take a look at the main mistakes made during this process, some simple errors that, as we will see, can easily be solved. Let’s see where many growers fail to germinate their seeds, it’s a great way to learn what not to do if we want to make the most of our seeds.

Letting the germination medium dry out
By placing the seed in a moist culture medium, it begins a series of reactions that will lead to germination in a few hours or days. Whichever substrate we choose for germination, we must ensure that it never completely dries out, because as the seed stops absorbing moisture, it’s likely that the seed will cease its activity and never germinate.

For this reason, it is advisable to check every day to make sure the germination medium remains moist, especially if a heat source is used to achieve a higher temperature and therefore a better germination rate; the heat will cause the substrate to dry more quickly, something that must be kept in mind to avoid nasty surprises. In case of hydroponic cultivation it is always better to germinate in rock wool cubes, which of course must always remain moist.
The paper towel should never dry out once germination begins
Leaving seeds to germinate for too long
Another common mistake, in this case when germinating in kitchen paper or similar, is to let the seed germinate until the cotyledons appear. If we do this, then the subsequent transplant is very difficult, and it is very likely that we’ll damage the root in the attempt. Additionally, the longer the root is exposed to air and light, the more damage will result, so it is preferable to transplant it before this occurs.
To avoid problems, it is best to plant the seeds when the tap-root measures approximately 1cm, or 2cm at the most. This will make it much easier to transplant and we won’t harm the development of the roots, which can be expand into the new growing medium without setbacks.

Direct germination in soil
This is a common mistake that usually results in non-germination, especially if the substrate hasn’t been previously watered before sowing the seed but is watered afterwards. By planting the seed directly in the substrate, we run the risk of it being buried too deep, made worse when we irrigate the growing medium post-sowing.
To obtain much better results, first germinate seeds in kitchen paper, jiffy pellets or peat plugs used for rooting cuttings and then transplant them to the soil or to a pot once the small seedlings have been born. Another benefit of this method is that we can germinate a large number of seeds in a very small space, such as a small greenhouse, which will make it much easier to provide the correct temperature and humidity.
Temperature and humidity for germination
Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.
The ideal is to maintain the germination medium at about 26-28ºC and at 70% relative humidity. Lower values will result in a slower and less successful germination, while higher values can bring fungal or rot problems.
A heated greenhouse is perfect for germinating seeds
Planting the seed incorrectly
If you look closely at a cannabis seed, you will notice that it has a slightly oval shape, ending in a point at one end and forming a small “crater” at the other end, which is called the crown. When planting your seed (whether it’s a seed that you want to germinate, for example, in a jiffy, or a seed already germinated on kitchen paper that you want to transplant) you must keep in mind that this crown should always be facing upwards.
So, you should plant the seed with the tip down and the crown uppermost and facing you. Once the seed germinates the crown will serve as a hinge, so that the seed will open at the tip and let out the root. In case of placing the seed incorrectly, the tap root will grow upward and the seedling downwards, which should be avoided at all costs because it is likely that the seedling will not be born.
Planting at the incorrect depth
Too often the seed is buried too deep (a problem that we have already seen in case of watering after planting the seed), so the seedling may never emerge. In the other case, if we sow too close to the surface, we can find that the seed germinates well but the stem grows weak, bending and not allowing the seedling to develop correctly.
To avoid these problems it is be best to sow the seed at about 2cm depth. In addition, we can cover the lower stem as the seedling grows, so that it gains stability and produces new roots along the length of stem we have buried. In this way we can accelerate the growth of the plants.
We should plant the seed with the root downwards
Planting several seeds in the same pot
Although it may be tempting, germinating several seeds in the same container is not usually successful. In addition to the difficulty of correctly planting several seeds in the same pot, once they are born they will compete for the little space available for their roots. Having restricted root growth does not suit cannabis plants, which will grow more weakly and with greater internodal distance.
In addition, the scarce space between the plants will also mean they will compete for available light, something not recommended if we want to get the most out of each plant. The plants will produce very little lateral branching, and will center their growth on a weak main stem, with too long an internodal distance, factors that usually affects negatively on the final yield of buds.

Comments in “5 common mistakes when germinating cannabis seeds” (49)
I’ve been growing since I was 13. I am 66. Not a boast. It just is. My comment is not so much about growing weed but rather about a lack of civility AND (not necessarily limited to only this forum). For the most part cannibis “enthusiasts” are wonderful people. Still, is it my imagination or are there a lot of condescending pricks (can I say that?) on these forums. Some of which are “Newbee Experts” criticizing anything that didn’t come out of their own mouths? When the Real Expert offers an opinion that doesn’t mesh with the self proclaimed genius’s vast knowledge base, they tend to respond with very little grace. So I guess this is more about the general state of things and what some people believe is acceptable behavior. Just a thought. Cannabis community, let’s treat each other with respect. We’ve made so much ground and it’s taken SO MANY years. Let’s not screw that up.
Just a quick poll for those of you with a few growing seasons under their belt. Have you found that your failure rate with seed germination has been increasing. I suppose it is possible that I’ve just had a bad run but my success over the last two grows has been about 50%. I’ve been doing this stuff for a long time and my technique is sound. Just seems like I have more duds lately (I have not purchased seeds from Philosofer).
I quit reading long back when the initial 100 seed results were reasoned. I’ll likely be missing many points observed. Simple opinion, for better than 25 million years of natural survival this plant has recreated itself for man to adapt to its uses in a very short 10,000 or how ever many years there’s been somebody crapping In a watermelon patch Surely it knows its way around a 2cm [email protected]&?ing hole surrounded by its predecessors environment. I would think genetically it knows what the !(@& to do. Especially if you are using a “Feminized seed”. Now, surely many observations have been made justifiable or not the laws of average are easily debatable, but I believe that the laws of average have established the standards many moons ago friends. Maybe I’ll fill up a kiddie pool 4ft Dia. @6 inches deep perlite and drop a 100 seeds through a pine bow from 6 feet high and then document the seeds position when it’s at rest in the perlite.. . I’m Extremely new to cuktuvating cannabis, my 2nd year. My first year turned out peesonally satisfiable at best simply because I planted shark cookies. I germinated in a paper towel, from there I rested the seed however it rested in a tub of perlite with an aquarium bubbler, also a circulator moving a solution of compost tea through the roots for 2 weeks, then put them in a small crawl area with a fan and a few lights for another 45 days, and then moved them to a bucket and put outside for the next 3 months and then brought back inside for another 2 weeks. So any opinions that we all have are open for discussion, but the only resolution for judgement is our own environmental abilities to nurture the development of variable genetics. Happy gardening friends..
Hi and thanks for your comment. We’re happy that your first year of cultivation was a reasonable success, we hope that this year will be even more so! Germinating seeds may seem like the most natural and easy thing in the world, and that’s how it should be, but it’s amazing just how many people fall at this first hurdle, and when the seeds are not particularly cheap, as in the case of cannabis, it becomes even more nerve-wracking, especially for beginner growers and those who have no basic experience of growing other plants like vegetables, flowers, etc. There’s no real substitute for experience in this game, and the more seeds we pop, the more confidence we get. Thanks again for your comment, best wishes to you!
Hello Good day I have some that looks like stale might be more than years old seeds. It was a given to me by a friend and I doubt it was preserved properly in proper containers. Will it still germinate?
Hi, thanks for your comment and question. The older the seeds are, the less chance they will germinate, and if they weren’t stored in good conditions (dry, cool, stable, e.g. in the fridge) then the chances of non-germination become even greater. You can try a few things to help improve germination rates, for example, the application of fulvic acid and/or gibberellic acid will give older seeds a better chance of germinating. Try germinating a few of the seeds in the normal way and then if you don’t get success I’d look at using one or both of the compounds I mentioned. I hope that helps, all the best!
I have germinated five seeds of different stains, all paper towel method. All sprouted.. All healthy.. All put in good seedling raising mix but the problem is they just sit dormant just not growing. I grow under lights. Last year.. No problems this year no growth. Seeds r less than a year old. HELP.
Hi and thanks for your comment. To work out the problem, we need to eliminate a few possibilities. First, check that the temperature and humidity levels within your grow area are suitable for vegetative growth: ideally from 20 to 28ºC with 40-60% RH. Then verify whether your lamps need changing – old bulbs put out significantly less light than new ones, which could be leading to poor growth. If all those factors are as they should be then the most likely culprit is the soil mix itself – the quality can vary from season to season, even with the best brands, so it’s always possible that there could be pests or pathogens in the soil which are preventing the seedlings from making progress. I would recommend trying with a different brand of soil to see if that makes a difference. I hope that helps. Best wishes and good luck!
I germinated in paper towel until tap root was as long as seed it curled around the seed anyway my question is if I planted in jiffy pod should I put it under light or wait till it pops up to put it in the light .
Hi and thanks for your comment & question. The newly germinated seed doesn’t really need a light source while it’s below the soil surface but as soon as it pops out it will need light to prevent it from becoming stretchy, lanky and unhealthy. For this reason, it’s probably best to keep it under a light with a photoperiod of 18 hours light and 6 hours darkness for the day or two that it takes to break the surface. I hope that helps, best wishes!
You’re incorrect, seeds should be planted pointy end up crown down.
Hi Master, thanks for your comment. I honestly don’t believe there’s a correct or incorrect way. In our time, we’ve tried germinating seeds point down, point up and also laying them on their side in the soil, and we’ve come to the conclusion that it makes no difference at all – we certainly didn’t see any real difference in the results of one method compared to another. In nature, cannabis seed dispersal doesn’t rely on the seed landing in the soil in any particular position and it’s managed to spread pretty well! That said, if you like to sow your seeds pointy end down, then that’s great, keep doing it your way if it works for you! Best wishes!
I had my seeds in the paper towel for 3 days. The tap-roots appeared(not out just showing a bit) and I planted them in the soil. 3 days have past and I haven’t seen any progress. Is there a reason why this is happening?
Hi Sean, thanks for your comment. As long as the soil is neither too wet nor too dry, there shouldn’t be a problem with the seeds. They can take a few days to pop their heads up above the surface once they’re planted, the root needs to work its way downwards and find a solid hold to be able to push the seed head out of the soil. Speaking from personal experience, don’t be tempted to dig around looking for them as you’ll probably do more damage than good. The only times that seeds didn’t come up for me were the times I overwatered them, it’s crucial that they get enough air at this moment and too much water can lead to them rotting quickly. Of course, if they totally dry out then they’re not going to survive either. At this stage, I’d just recommend patience, good luck! Best wishes!
This article has a lot of nonsense in it. From Mandala Seeds: A #1 seed killer is a closed humidity dome/mini-greenhouse. Humidity domes are only required for rooting cuttings. Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot! Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%. Btw, seed should be planted with the pointed end UP, not down. Tap root ALWAYS goes up no matter how you place the seed. It’s by the nature, goes against the gravity to create a support for itself so it can push the seed out. It you put it with the pointed end down it will have to make double turn loosing the precious energy stored in the seed.
Hi, thanks for your contribution. Mandala Seeds give some helpful advice but they don’t have a monopoly on germination methods! In my 20 years germinating seeds I’ve tried all different methods and I’ve found good and bad in all of them. except for the methods using moist paper towels, I refuse to use it these days – I found that’s a great way to get mold problems and a really bad start to the plant’s life! That definitely is far too much humidity. as for ambient humidity, we don’t specify anything in this post. What we do say is that the medium in which the seeds are germinating should be at about 70% humidity for the best results. There’s nothing wrong with using a humidity dome or mini greenhouse, as long as you know when to start ventilating. of course if it’s kept sealed all the time then problems are bound to arise! These days I start all mine in a glass of water with a few drops of H202 and then once the seeds open (usually 24 hours) they get transferred to the substrate. As for the point down/point up debate, I think I’ll need to do a side-by-side comparison to settle this in my own mind. I’ve always planted them point downwards or on their side and I’ve yet to see any weird stuff like roots popping out of the surface, or doing a loop-the-loop before the seedling breaks the surface. But it’s clear that the debate needs to be settled so I’ll do an experiment and I’ll be happy to be proved wrong! EDIT: I’ve since germinated over 100 seeds as a test, 1/3 of them went in the soil with the point downwards, 1/3 sideways, and 1/3 with the point upwards. Most of the seedlings broke the surface at around the same time but it’s clear to see that the ones that I’m still waiting for are mostly those that went in with the point upwards. The next step has to be a test in a terrarium so I can actually see what’s going on but I’m almost ready to call complete BS on this “point upwards” theory, FWIW. Thanks again for your comment, all the best!

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.

5 Fatal Mistakes For Germinating Seeds
It’s a few weeks before spring, and gardeners everywhere are starting baby plants from seed. Germinating seeds isn’t usually a difficult process, and for most veggies, the process is quite simple.
For complete instructions for starting seeds, get the seed starting guide.
But what do you do if your seeds don’t germinate?
When seeds don’t sprout, you should always take time to evaluate what happened. So I thought it would be helpful to talk about the most common reasons you might have seed germination problems.
Some years our germination is a little patchy, and occasionally whole rows of seedlings will not germinate. It is important to keep up with our germination rate to evaluate our technique and seed health.
For us, a minimum acceptable germination rate is when at least 80% of our seeds sprout. But ideally, 100% of our seeds come up, so anything less than 80 or even 90% germination rate, and we start looking at what went wrong.
Learn the 5 fatal mistakes for germinating seeds
When vegetable seeds are not germinating, there are a few common problems that you should look for.
1. You used old seeds
The first thing to consider is whether the seeds were viable in the first place. If your seeds have not sprouted within the appropriate number days (this will depend on your seeds), then you may want to consider using a pen or pencil to gently dig around in your soil and find the seed.
- If you don’t find the seed, think back. Did youforget to put the seeds into the mix? Don’t laugh! It could happen!
- If you find the seed, take a good look at it. You may see that it looks just the way it did when you put it in the soil. In this case, the cause for a low germination rate might be that it was an old seed or not properly stored.
If you have some old seeds and are unsure of whether your seeds were viable, you can always sprout a couple of them in a wet paper towel to check prior to planting.
For new seeds or seeds you saved last year:
- When you saved seed, did you put them away without letting them dry completely? This can cause seeds to rot or mold.
- Were they exposed to extreme temperatures during storage? For example, if you left seed packs in your car over the summer. High temperatures over 90 can kill the plant inside the seed.
- Was the parent plant healthy? Seeds can harbor infection from the parent plant that may prevent sprouting, however, this is not usually the case.
2. You didn’t use new or sterilized containers
Disease issues can be a factor in seed germination. Think back to last year and whether you had any disease issues with your seedlings.
- Most plastic containers can be reused for several years, but they need to be sanitized.
We clean ours by submersing them in bleach water at the beginning of the season.
If you are looking for a bleach alternative, try the environmentally friendly bleach alternatives that use hydrogen peroxide as their active ingredient.
Fungal and mold infections are the most common infection from dirty containers. If infection occurs you will notice a fuzzy growth on the top of the planting medium.
- You may also see that a seed sprouts, but then rots at its base and falls over.
This is called damping off and is caused by a funal infection in your soil. A hydrogen peroxide or colloidal silver solution can help treat fungal disease on your tender plants.
3. Your technique is not right
- If you started seeds in any mix that includes non-sterilized soil from the yard, your seeds may have been affected by disease organisms in the soil.
In order to use garden soil for starting seeds, you should sift it carefully to remove sticks and clumps. Then bake it on a cookie sheet in the oven at 180 degrees for 30 minutes. That should kill most weeds and pathogens.
You’re better off using a seed starting mix. Seed starting mix is usually a soiless mixture that has a finer grain and is free of clumps, sticks, and pathogens.
- Did you plant your seeds too deep?
Planting your seeds too deep can cause problems with sprouting. You should also avoid pressing down on top of your seeds after you plant them. If the soil in your container is too compacted, the seeds cannot sprout or form healthy roots.
4. You didn’t provide the correct temperature
The temperature of your soil is of utmost importance in getting a good seed germination.
- Temperatures that are too high or too low can cause problems germinating seeds.
Given all else is equal, even tray germination requires even temperatures. If temperatures plunge at night, or peak over 100 for a prolonged period, seeds will either remain dormant or die.
- Did you leave the heat mat too high or too low?
Even when using seed starting heat mats, accidents happen. If you forget to put the temperature probe into the seed tray, the heat mat can overheat and cook the seeds.
Sometimes heat mats get accidentally turn off, or you forget to plug it in.
An alternative to the heat mat is to put them in a sunny south facing window or on top of the refrigerator. You can also use grow lights to provide heat above, and I have even seen people use rope lights to generate warmth.
5. You watered incorrectly
Seeds need to be moderately moist to sprout.
- Seed germination is highly dependent on watering. Too dry and they won’t get the message to sprout, too wet and they will rot in the dirt.
Very young seedlings are even more tender. Seedlings do best in what we call the “Goldilocks zone.” You know Goldilocks. She likes her porridge not too hot and not too cold, but juuust right.
- Tender seedling babies can’t tolerate drying out. While young, even a short dry period can mean death after the first wilt.
On the other hand, their tender roots will be the first victim of conditions being too wet. They can’t get the oxygen they need to carry about their business, and it will stunt or kill the seedling.
