12 Tips for Sprouting Cannabis Seeds
Every tiny cannabis seed represents a potential pound of cannabis flower. It’s crazy to think that so much abundance springs forth from such a small thing. If you’re looking to grow cannabis plants this summer, get started now with a visit to KindPeoples’ award-winning Genetics Department, where you can browse hundreds of strains in seed and clone form and pick the perfect plant to grow.
Once you’ve found the plants you’re looking for, getting started with growing cannabis is easy.
Simply follow these basic tips for germinating your seeds and planting them in soil.
- Look for viable, plump seeds with a telltale “tiger stripe” on the side that indicates maturity. Larger seeds tend to yield more vigorous and hardy plants.
The most common reason for lack of germination is overwatering. Don’t let your seeds get too wet or they can drown, and don’t soak for too long or they will begin to rot. If the seeds haven’t sprouted after 48 hours, let them go another day, but after 5 days the seed is most likely dead.
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.
A germinating cannabis seed
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.
We hope that this article will help you avoid problems when germinating your seeds, it can be very frustrating to start a grow with all the enthusiasm and excitement, only to run into problems straight away!

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!

Reasons Cannabis Seeds don’t Sprout
Top Reasons Your Seeds Aren’t Sprouting – And What You Can Do About It
Seeds are designed to sprout, but that doesn’t mean it’s easy. Some seeds sprout just about anywhere, whereas may need very specific conditions before they will crack. When it comes to marijuana seeds, sprouting should be easy, but there are times when the germination rate just isn’t what it should be. When this happens, it’s crucial to look at every part of the setup to determine what went wrong and what can be done to get the seeds to sprout.
Diseases or Mold Killing the Seeds Before They Get Started
Seeds can suffer from diseases and mold just like the plant can once it starts growing. Diseases can kill the seed before it gets the chance to start growing, and mold can cause the seed to die during the germination process. Fungi can also be an issue, as it can cover the seeds and prevent them from being able to sprout. Once diseases, mold, or fungi start to grow, there isn’t much that can be done to save the seeds.
What to Do About It:
Seeds can be soaked in diluted hydrogen peroxide for a few hours before planting. This kills any diseases that could be growing outside the seed so they have the best chance to grow. Watering should be done only as needed to prevent the growth of mold and fungi. The humidity in the room should also be carefully monitored to prevent the growth of mold and fungi and growers should ensure they have good ventilation if they are growing weed from seeds indoors.
Bugs or Other Pests Eating the Seeds or Seedlings
When growing outdoors, it’s easy for pests to devour the seeds. Bugs like to eat the seeds, and birds will often look through the garden and pick out any seeds they can find. Birds are often one of the biggest pests when planting seeds, even though they will be beneficial once the seeds have sprouted by eating caterpillars and bugs that might like to eat your sour deisel seeds or gelato seeds marijuana plant. Birds can destroy an entire crop of marijuana before it even gets started because they will search the area carefully and eat all of them once they know the seeds are there.
What to Do About It
The best option to protect seeds from pests is likely to germinate the seeds indoors. Once the seedlings are a couple of inches tall and they have their first set of true leaves, they can be transplanted in the garden and the birds will leave them alone other than to check and see if there are any bugs on the plants that they can eat. Another option is to use row covers. These can be inexpensively made and will cover the seeds completely until they start to grow. There are plenty of options for keeping birds away from the garden to protect the seeds, depending on what’s already on hand and what is more effective.
Seeds Aren’t High Quality
When seeds are low quality, they’re not going to have a high germination rate. Very few of the seeds are going to sprout and those that do may grow a plant that dies quickly or that suffers from issues while it’s growing, leading to a reduced crop. Buy cannabis seeds, purchased from a reputable seed bank, are designed to have higher germination rates and lead to much healthier plants. They have been tested for higher germination rates, so growers have one less thing to worry about when they’re starting the seeds.
What to Do About It
There likely isn’t much that can be done about low-quality seeds to get them to sprout. It may be possible to soak them in water to soften the shell so they will sprout, but the resulting plant might not be healthy either. Even with that trick, it can be difficult to get low-quality seeds to sprout at all. Instead, it’s best to always purchase high-quality
cbd seeds or thc seeds from a reliable seed bank to ensure the germination rate is as high as possible.
Seeds are Too Old
Seeds should be planted soon after they’re purchased, but many people will order seeds early and wait to plant them. Depending on how long they wait, the seeds will likely be fine. However, seeds will become less likely to grow if they are stored for years before being planted. If you find old feminized weed seeds or other random unlabelled pot seeds in an old cupboard that have been stored for a significant amount of time, the germination rate simply isn’t going to be what it would be if the seeds were planted earlier. High-quality seeds can be stored longer, but still may not sprout.
What to Do About It
Seeds should ideally be planted within a year or two of purchase to ensure the best germination rate. The length of time before a seed is no longer viable can vary, but most seeds will still have at least a decent germination rate if they are stored properly and used within two to three years. The germination rate will decrease further with time. Proper storage means the seeds are kept in a cool, dark place and away from moisture until they will be planted.
Too Much or Too Little Water During Germination
Water is necessary for seeds to sprout, but too little or too much can make a huge difference in the chances of success. Too little water means the shell will be too hard, so the seedlings won’t be able to push their way out. Too much water for seeds started in soil can lead to the growth of mold. Seeds can be started in water to help them sprout faster, but once they begin to sprout, they should be planted in soil to prevent issues.
What to Do About It
Water only when needed. If the soil starts to feel dry, go ahead and water it to ensure there is water for the seeds. Never let the soil dry out completely before watering it again. If the soil still feels moist, there is enough water for the seeds, so wait another day or two to water. Keep a close eye on this during the summer months especially to ensure the soil doesn’t completely dry out during the hottest days.
Seeds Are Getting Too Much Light
Marijuana Seeds should be not just be dropped in the soil and covered with just a light layer of soil on top of them. This not only welcomes seed-hungry pests like birds into yoru garden, but also doesn’t give you much control over the consistency of water and light that they are provided. You wan’t to mimic the conditions that nature provides for idea seed growth: moisture, warmth, and darkness.
What to Do About It
Follow our i49 germination guide and sprout yoru seeds in a damp paper tower. This setup should be kept in a awarm and dark place like a cupboard inside your laundry room or in a box on top of your fridge. If possible some ventilation is helpful rather than a tightly enclosed space, and it is also a good idea to rinse yoru seeds periodically to prevent the development of mold. As soon as you see a taproot emerg, you can remove from the paper towel and transplant to a small amount of growth medium.
The Weather Isn’t Right for the Seeds
When your autoflower weed seeds are planted directly in the soil outdoors, the weather can have a huge impact on reducing the germination rate. If the seeds are planted too early, it may be too cold for them to sprout. If the seeds are planted too late, it could be too hot. Marijuana seeds prefer a warm temperature to sprout and may not start growing if it’s below 60 degrees or above 80 degrees Fahrenheit. Some seeds may start to sprout despite the temperatures, but the germination rate will likely be far below what is expected if it is too hot or too cold for the seeds.
What to Do About It
Always germinate your i49 seeds using our recommended germination methood. This will help give the seeds the best chance to grow. Indoors, the temperature can be more carefully controlled and once the seedlings are large enough and the temperature outside is warm enough, the plants can be transplanted to the outdoor garden.
The Bottom Line
If you’re planning on growing marijuana in the USA, use the tips here to ensure your seeds are more likely to sprout and that you’ll have a higher germination rate. The proper preparation can make a huge difference in how successful you’ll be and can help you cut down on many of the potential problems and frustrations that could lead to seeds failing to sprout.
