How to prevent the death of cannabis seeds and seedlings

Causes of death in cannabis plants

Every grower, almost without exception, will have occasionally suffered the death of a plant during cultivation, just when it seemed that everything was going along nicely. In this article, we'll focus on the main reasons why seeds may not germinate properly, or why seedlings may end up dead in the first weeks of life.

Seeds dying before germination

Cannabis seeds can die even before we start to grow them, in which case, when the grower comes to germinate them, they won't open up and sprout at all.

The seeds of the cannabis plant, like many other types of seeds, must always be kept in the correct conditions, especially if you want to save the leftover seeds for later use and ensure that they germinate well in the future.

The same goes for unopened whole packs of seeds that have been purchased to store for later use. Sometimes, certain varieties are in high demand and there is limited stock, so the more astute growers will make sure they grab a few packs to keep in the vault until they find the time to germinate the cannabis seeds.

What to do with leftover seeds or unopened seed packs

Cannabis seeds need very low relative humidity and relatively low temperature for their proper storage, so the best plan is to keep them in a "no frost" refrigerator, in which both the humidity and temperature are maintained at very low levels for better conservation of food.

If we want to keep a seed package that's still sealed, simply put the whole unopened pack into the fridge. The best place for its conservation is usually the small shelf where the eggs or butter are kept, although really any part of the fridge is ideal for storage.

If we want to save the leftover seeds from a pack for later use, we recommend storing them in the original Eppendorf tube or container used by the bank. In the original packaging, these Eppendorf tubes hold the seeds and usually also contain a few small silica gel balls, included to maintain very low humidity (10 to 20%) and help to ensure that the seed does not lose any germination viability.

If, however, we leave the seeds for a long period of time in any corner of the house it is possible that over time their viability to germinate will decrease, and when we plant them they may take a long time to germinate or indeed not germinate at all. it is also important to protect them from sunlight.

So if you wish to save the seeds in the best conditions, always keep them in the refrigerator, well protected from air, light and moisture.

Death during the germination of cannabis seeds

Death during the germination of cannabis seeds is one of the most frequent failures suffered by every grower over the course of his or her cultivation career. There are several possible reasons that can lead to the seeds dying before they even open and begin to grow, which we'll examine here.

Not all seeds have the same resistance to the errors that may occur during the germination process. Just as not all siblings are not all equal, neither are all seeds. By this, we mean that in the case of one seed germinating and the rest of them not doing so, it doesn't necessarily mean that those that didn't germinate were not strong or resistant, but simply that they were less so than the one that did germinate. If this occurs, we must ask ourselves why they did not germinate and look for any possible failings in the process.

Death by drowning the seed during germination

We start from the basic premise that the seeds require moisture, oxygen and a suitable temperature for germination; If one of the three aspects is not taken into account, it is quite likely that the seeds won't end up germinating.

Putting the cannabis seeds in a glass of water and waiting 24 to 48 hours for their germination can be a fatal error for them. Re-hydrating the seeds in water is a good idea as long as they are not out of contact with the air for long, as they will be deprived of oxygen and most of the time they will end up dying; so if we use this method, we only leave them to re-to hydrate in water for a few minutes, although, preferably we will avoid any previous soaking or re-hydration (which in any case is not necessary).

We must ensure the correct levels of humidity for germination
We must maintain suitable levels of humidity for germination

The reason for this is that tap water contains chlorine, which sterilises the water to make it suitable for domestic use. However, this chlorine disappears by evaporation after a few hours, so if the water then gets contaminated, the seed can be attacked by any number of pathogens and eventually die. This example also illustrates why we must always touch the seeds with clean hands; If the seeds are handled with dirty fingers, it can lead a fungal or bacterial infection to contaminate them and severely compromise their development.

The same can happen in other germination media such as jiffy plugs, where the most common mistake is usually not draining away the excess water after re-hydrating the compressed peat. To this error, we can add that of burying the seed at more than twice its own depth, in which case it may not emerge despite having germinated perfectly well, but instead, simply end up rotting due to excess water and lack of oxygen. This error is also frequent in growers who germinate directly in the soil because when they first irrigate, the seed can be washed down into the soil resulting in them being buried too deeply, which makes it difficult for the seedling to reach the surface. It is always better to wet the substrate first, before sowing any seeds.

If you want to sow the seed directly into the soil and do it properly, when growing outdoors you must also act to prevent seed predators. Ants, birds, and many other animals or insects are another common cause of seed failure during germination. In the case of ants, they eat the small, delicate root, leaving the plant unable to develop and condemning it to imminent death.

Placing the seeds between moist serviettes/paper towels is one of the best germination methods for beginner growers. Since you can easily see if the seed has taken root or not. But we must also bear in mind that the germination medium, the kitchen paper, is made of cellulose, meaning it is an organic material that will decompose and rot, just like any product of this type.

Planting the germinated seed is also a vitally important moment
Planting the germinated seed is also a crucial moment

It is, therefore, obligatory to change the napkins every day and a half, more or less, to avoid the seeds being contaminated by the pathogens that can appear as the napkins begin to rot. For this reason, we recommend placing the napkins in a deep plate and covering it with another one, leaving a small gap between the two so that air can enter, oxygenate the microclimate that is created during the germination of the seeds and avoiding them rotting.

Seeds dying due to lack of moisture

Just as excess water is one of the most common causes of germination problems, the lack of moisture is equally detrimental to the process.

If outdoor temperatures are around 20 to 24ºC, then we shouldn't need do much more than start the seeds to germinate and wait for them to open, following the precautions already discussed. But in case of having warmer or cooler temperatures, we must act to raise or lower the environmental temperature for optimal germination, and find the best location for germination to be successful.

If it is winter, the plates holding the seeds are often placed on top of a low heat source to raise the temperature. We must, however, be careful: if this heat source emits hot air, the paper towels will dry out and the seeds will run out of moisture, affecting germination. If you realise this in time, you can re-hydrate the seeds and they will usually recover from and continue to germinate, although it is also possible that there will be consequences that may affect the subsequent development of the plant during its cultivation.

Not long after sowing the seed, we will see our little plant emerge from the soil
Not long after sowing the seed, we will see our little plant emerge from the soil

If we haven't noticed soon enough that the seeds have been left without moisture, we can assume that they will have dried up completely, with their consequent death, and this is even more likely if the seeds had already opened up to show the root. This can also happen very easily if we germinate during summer when temperatures are high and humidity is usually very low compared to other times of the year.

Death of the plants during the growth period

The start of the growth period is a very important stage in a plant's life, so several aspects must be taken into account so that it does not die of any of a number of causes.

One of the most frequent problems is root rot due to excess irrigation and lack of oxygen in the substrate. Up till now, this has been one of the most common causes of plant death during the growth period, especially with beginner gardeners who lack previous cultivation experience. In addition, the likelihood of this happening increases considerably in crops with auto-flowering varieties; we'll explain what to do here.

When the plant emerges from the substrate, leaving behind its germination stage, it is crucial to take care with any excess water and the lack of humidity in its aerial parts such as leaves, stems and branches.

The proper conditions guarantee good germinación
The proper conditions guarantee good germinación

When the plant is young and only has a very small root, its needs are few, it feeds and drinks very little. If we saturate the substrate with too much water, apart from halting the growth of the root (leading to little or no growth in the aerial parts), it creates the ideal conditions for the small roots to slowly rot. If the plant loses a part or all of its tiny root system in its first stage of life, it is almost guaranteed that it will die within a few days.

If we use a small 0.5L to 1L plant pot for the first part of vegetative growth, before transplanting them to a bigger pot, we will be covering our backs in case of any excess of irrigation, since the substrate will dry out again much faster than in larger pots. For this reason, this issue is very common for novice growers who are cultivating auto-flowering cannabis plants, where the use of 20L pots is recommended from the start.

It is often said that you must irrigate with an appropriate amount of water and nutrients for the size of the plant. As this is often complicated to carry out, as a rough guide we can irrigate the plants with an amount not more than 10 or 20% of the plant pot's capacity. So, if they are 1L pots we will water from 100 to 200ml as long as it is not an auto-flowering plant.

If the plan is to grow automatic varieties, then during the first two weeks we water with 100 to 350ml per irrigation, every 1 or 2 days. Remember that the substrate must maintain a minimum of humidity to allow the plant to feed and continue to develop normally. If it is raining and the plants are outdoors, it's a good idea to move or cover them, to prevent the substrate from getting soaked, which could easily lead to root zone problems.

My auto seeds are just starting to poke through the soil in my solo cups( no cotolydons yet) Can I move them outdoors to get sun. I plan to grow them outside. Thank you

Alchimia Staff

Tim Alchimia 2021-05-27
Hi, thanks for your comment. I'm glad to hear your seeds have popped up! You can definitely put them outdoors now and they'll develop even faster than they would indoors. Try and make sure that they are well protected from potential pests such as mice, slugs, snails and birds - all capable of killing your baby plant before it develops its first set of true leaves. It's a good idea to place the seedlings in a semi-shaded area for the first few days, and if they're outdoors from day one they'll quickly adapt to full sunlight. I hope that helps, best wishes and happy growing!


Natalie 2021-03-31
Hey I germinated a couple seeds successfully but one of the sprouts was knocked off in the process of planting it :( Will it still grow? What should I do?

Alchimia Staff

Tim Alchimia 2021-04-01
Hi Natalie, thanks for your comment. Sorry to hear about your misfortune. It probably won't grow I'm afraid, losing the taproot is pretty much the end for the seedling. If I were you I'd germinate another seed to replace it ASAP. Best wishes and happy growing!


KoolBreeze420 2020-12-30
Have you ever had to remove the seed shell manually? If yes how? My seedling has come out of the soil wearing a hat should I leave it will it push it off or when should I intervene? I read that a seedling can die if it can't shed its hat.

Alchimia Staff

Tim Alchimia 2020-12-31
Hi, thanks for your comment and question. It's happened to me quite a few times and how I deal with it depends largely on what the seed is. If it's an expensive or rare seed that I really want to keep then I will gently ease the seed casing off the seedling, being very very careful not to damage the cotyledons (the seed leaves). Misting the head of the seedling with water beforehand will help the process. If, however, it's not a particularly special seed or it's one that I have more of, then I'll just leave it to its own devices, reasoning that if it's strong enough to shed the seed casing by itself then it'll survive and if not, then it wasn't really tough enough or vigorous enough to warrant investing my time and energy to grow it! I hope that helps, best wishes and happy growing!

What reasons could there be for a sudden and continued failure to germinate after years of germinating in the same way, always successfully?... My friend has changed nothing whatsoever, germinating, as always using the paper towel method yet the last three times she attempted this, all have failed, at most popping and showing their insides but not developing or hardly developing a taproot? She's tried changing seed suppliers, different types of water, from tap to distilled to bottled, tried several different paper towel types and all are failing. Any ideas? It's mystifying!

Alchimia Staff

Tim Alchimia 2020-11-02
Hi Bob, thanks for your comment and question. It's a curious situation and there are so many different factors that could affect the outcome. The first things to examine are the temperatures at which the seeds were stored and the temperature for germination. Ideally, seeds should be stored in the fridge, and high temperatures or poor sorage will definitely affect the viability of the seeds. Next, if the temperature for germination is too high or low, that will also have a negative effect. From 20-26ºC is ideal. The next thing to examine are the humidity levels, it's important that the germinating seed doesn't dry out or become waterlogged, both of which would halt growth and most likely kill the seed. If the seeds are opening but not developing any further then this may be the cause. Personally, I never really liked the paper towel method, so let me share the germination method that I use with almost 100% success, for hundreds of seeds, year after year: I take a small cup, jar or shot glass and fill it with water (it can be RO water, distilled water, mineral water or spring water) and then add a generous splash of 3% Hydrogen Peroxide before adding the seeds (this helps to sterilise the water and to add oxygen to it). I place the glass in a warm, dark place and within 24-36 hours I usually see the seeds opening and the root tail emerging. Incidentally, I've read that if the seeds float in water then they're not viable but this is completely false as most seeds will germinate perfectly while floating on the water surface. Once the tail is out, I transfer the germinated seed to a jiffy pellet of a small pot with substrate, planting it 0.5-1cm below the surface, with the root tail pointing downwards. I normally see the seedling poke it's head through the substrate after another day or two although sometimes they can take uo to 4 days to emerge. While you wait for this it's vital to monitor humidity and not allow the seed to dry out or become too wet, taking great care not to over water as this can easily cause the root to rot. I hope that helps, please let us know if this works for your friend. Best wishes and happy growing!


Korp borp 2020-08-12
Is it a good idea to leave some type of clear solo cup on top of where the seed was planted because it keeps that one area very moist but I don’t know if that’s a good thing or should I remove the solo cup P.S. I have holes poked in solo cups and spray inside with mist bottle water ph to 6.5

Alchimia Staff

Tim Alchimia 2020-08-17
Hi and thanks for your comment. The method you describe can be really helpful to protect the germinating seed if conditions are particularly dry, but it can also lead to very high temperatures if, for example, the full midday sun hits the solo cup directly. If you can place the cup out of direct sun then I think it's a great little mini-greenhouse to start your plant off. Just don't let the humidity get out of control, you might not need to spray inside the cup very often to keep levels in the comfort zone... too much moisture and you may well end up with stem rot or Fusarium issues! I hope that helps. Best wishes and happy growing!


Bittu 2020-08-11
Saplings sprouted but 3-4 days later the stem bends and thins out and dries Like the stem bends day 1 and the next 3 days it's dead what do I do :)

Tim Alchimia 2020-08-11
Hi, thanks for the comment, It's hard to tell from your description but it sounds like a case of a fungal pathogen infecting and killing the young plants, the most likely culprit being Fusarium which can be caused by overwatering or by using infected soil. The first few weeks are crucial and if the plant has too much or too little water it will die. Using beneficial microbes like Trichoderma in the soil can really help avoid these problems happening. I hope that helps, best wishes and happy growing!


annoymous 2020-08-06
Hey so I checked on the seeds again and the root feel off and with a little squeeze the whole seed turnt to white mush and it smelled. Is that normal?

Alchimia Staff

Tim Alchimia 2020-08-07
Hi, thanks for your comments, I'm really sorry to hear about your seed! It sounds like some kind of fungal pathogen was responsible for the germinated seed rotting. Did you plant it in new soil or reuse old substrate? Old soil can often carry spores of harmful pathogens like fusarium, which can cause the problem you've experienced. This, possibly combined with slight overwatering, could have been responsible for the death of your seed. Using fresh substrate and adding some hydrogen peroxide to the irrigation water could prevent it happening next time. I hope that helps, best wishes!


annoymous 2020-08-05
Hey so I germinated my seed but when I planted them in a small pot they wouldn't sprout and its been 5 days already. I opened the soil to see the seed and it's still the same(seed a top with an inch whitetail.) it refuses to sprout even though i followed most guidelines of not overwatering, not to plant too deep ect and I don't know what to do now. Any ideas? Thanks


Di Is an Alchimia client 2020-07-18
I am a newbie. I live in Spain. Is it too late to grow from seed please. Every seed I have planted this year has died after growing it's first leaves.

Alchimia Staff

Tim Alchimia 2020-07-20
Hi Di, thanks for your comment and question. I'm sorry to hear about the trouble you've had with your seedlings, hopefully, you've picked up some useful info from our post! we find that overwatering and over-fertilising are by far the most common reasons for plants to die at a young age, so be aware of that next time you start... most of the time, the plants will grow just fine on their own and too much "care" can be a bad thing! Our Growing Guide has lots of articles that can help you, including a whole section on growing outdoors. As for this season, if you plant Indicas or fast-flowering varieties now, they will begin to flower at a very small size and give rather low yields, due to the photoperiod, so if you really wanted something of that sort then you'd need to plant a lot of seeds to compensate for low yields, making it a fairly expensive proposition. If however, you have good weather well into Autumn then you could probably grow something Sativa or at least Sativa-dominant, which would begin to flower a bit later and hence get more vegetative growth, reaching a larger size and delivering heavier yields per plant. I'd highly recommend going to our Seed Selector and selecting the filters "Sativa Indica" or "Sativa" (or maybe Haze genetics too) along with "Easy To Grow" and any other filters relating to effect or flavour that might appeal to you. I hope that helps, best wishes and happy growing!


Trygrow2 2020-05-30
Hi, I have had a problem where my seedlings sprout but the seed casing is still intact and compressing the leaves of the seed. They go several days partially stuck inside the seed casing and it seems to stunt their growth and progress. One even toppled over from the weight of the seed and died. Should I be helping the sprouts out of the seed case? The one that died did not root at all.

Alchimia Staff

Tim Alchimia 2020-06-01
Hi, thanks for your comment and question. What you're experiencing is a fairly common occurrence, and how to deal with it depends on each grower. Some growers will gently and carefully open the seed casing to help the plant to sprout while others will simply leave the seed casing on, reasoning that if the plant is strong and vigorous enough then it will fight its own way out! Personally I prefer to go for the second option, because if a plant can't break its own way out of the seed then I'm not sure if it has the necessary vigour to be in my garden. However, there are times when it's a special seed or a variety that I only have very few seeds of, then I will help it out of its shell. You'll need to be very very careful indeed because it's quite easy to damage the stem or the cotyledons (seed leaves) during the process. A damaged cotyledon will slow development but isn't terminal, a damaged stem often is. I hope that helps, good luck and happy growing!


Mrmail 2020-05-30
I try to growing twice. First all my seeds grow up healthy but stay in seedling. Then they never grow up and die. Second they stay in germination .after ten days nothing happens . Just two of them germinate but I am not wishful. I use good mixed soil planter irrigation andetc. Temperature is about 38 c humidity is low. I put them directly in sunlight outdoor. I change my seeds twice .I m confuse and angry now. What is wrong?

Alchimia Staff

Tim Alchimia 2020-06-01
Hello and thanks for your comment, I'm sorry to hear you've not had much success so far. I think you will have better results with your plants if you can keep the temperature and humidity conditions within the comfortable limits for cannabis seedlings. Between 20-25ºC is a perfect daytime temperature, a little cooler at night, with humidity levels of 65-70%, particularly important in the early stages of the plant's life. 38ºC is really far too hot, especially for young and tender seedlings, and this, accompanied by the low humidity meant that they never really stood much chance, I'm afraid. Once the plants are passed the seedling stage they can deal with higher temperatures and lower humidity, but these conditions are vital at the beginning. Strong sunlight can also badly damage young plants, so it's best to start off in a semi-shaded area and allow plants to gradually get used to the sun's rays. More isn't always better! I hope that helps, best wishes and happy growing!


Deedo 2020-04-07
Hello I recently bought 5 plants and named them after the TMNT and their master, our one plant, micheal angelo, grew very strong as its first few days and even grew out of its two baby leaves, recently the stem has gotten skinny and the top half is wilting, do you thing it can be saved. Master splinter he is standing tall, but the middle of his stem is skinny and dehydrated and i was wondering how i could fix this

Alchimia Staff

Tim Alchimia 2020-04-08
Hi Deedo, thanks for your comment and question. I like the idea of naming the plants after the TMNTs, nice one! I'm afraid it's going to be difficult for me to guess what's wrong with the plants without some more information on their growing conditions, so if you could provide further details then I will do my best. Probably the most common cause of problems in these situations is over-watering, so I would recommend checking that isn't the case here. Allow the pots to dry up slightly between waterings and avoid keeping the soil wet all the time, this reduces oxygen in the soil and can lead to all sorts of issue with the plants. Over-fertilisation is another very common issue, and for this reason, we often recommend to use half-strength doses of nutrients, especially in the early stages of plant growth. I hope that helps, but if you can tell me some more about the growing conditions I'll try and help more! Best wishes and happy growing!


Fireman420 2020-03-18
First autoflower grow,I was wondering if it is normal for the newly sprouted girls to have there " heads ` downwards toward the soil ? Didn't recall this behavior from reg seeds, thank you for your time and input

Alchimia Staff

Tim Alchimia 2020-03-19
Hi and thanks for your comment. When the seed germinates and the plant first pokes its head above the soil surface, it's usually bent over and curved so that the tips of the leaves are facing downwards, towards the soil. Don't worry, this is perfectly normal and ensures that the leaf tips don't get damaged as they push through the substrate. Within a short time, the plant will start to point skywards as it develops. I hope that reassures you! All the best and happy growing!


Sophia Williams 2020-02-26
I had a small seedling growing around the height of the little plant you have in one of your pictures. I accidentally tripped on it and it hit the floor and spilt over. Some of the soil around the seedling came out because it took a hard fall. Would it die from the impact because the layers of soil, peddles and sand have been mixed up and there are pebbles appearing at the top?

Alchimia Staff

Tim Alchimia 2020-02-27
Hi Sophia, thanks for your question. Sorry to hear about your little accident! As long as the seedling itself hasn't been broken at the base or along the stem it'll probably survive fine. I'd just water it gently to settle the soil back in place and then wait for the plant to recover. They really are quite resilient and can put up with a fair amount of abuse. The accident may well delay its development for a short while, but in the correct conditions, it should be growing again soon as long as no serious damage has been incurred. I hope that helps, all the best and happy growing!


Jay 2019-10-30
I have a new shoot that was growing fine, and sprouted two leaves, but then it started to wilt and the leaves curled and shrank. It's still green, but the upper half of the stalk is shriveled (the lower half looks robust). I am not sure what went wrong, but the top half looks like its health is declining quickly. Is there anything I can do to save it or restore growth? Can in transplant the section with the leaves? Again, the bottom half looks fine, but the top half of the stalk is shriveled.

Alchimia Staff

Tim Alchimia 2019-10-31
Hi Jay, sorry to hear about your plant. You say the upper part has wilted but the lower part looks healthy for now, but are there any leaves or nodes on the lower part or is it just stem? If there is a set of leaves or more on the lower part then you can remove the unhealthy part and see what happens. If, however, all that's left is stem with no leaves, then I'm afraid it's curtains for this plant, it needs a leaf node for it to be able to continue growth. You mention transplanting, but what are you hoping to achieve by that? Do you think the issue is with the substrate you're currently using? If not then it'd be better to leave it where it is and avoid more stress for the plant. It's hard to be sure but it sounds to me like the problem could be "damping-off" or Fusarium wilt in which case it's probably best to start again with new soil and clean pots, taking great care with hygiene and treating the soil with beneficial microbes like Trichoderma which will help to protect plants from fungal pathogens. I hope that's some help, please let us know how you get along. All the best!


Eren 2019-10-11
I was wondering if it’s possible to save seeds in the fridge for a few months after they already germinated? I placed a Moist paper towel in a small plastic container and put the seeds in the middle of the paper and covered them up so the moisture doesn’t escape. Would they survive for about 5 months or so as long as I kept the paper towel moist and replaced the paper every so often?

Alchimia Staff

Tim Alchimia 2019-10-14
Hi Eren, thanks for your question. I've never tried to do what you're suggesting, but I'm afraid I can't see the seeds surviving for very long at low temperatures once they've germinated. When the seeds open, the whole biological process of plant growth is initiated, and while we can slow these metabolic processes down with low temperatures, after a certain time the young plant will suffer cell damage and die, or it will be weakened sufficiently to allow fungal infection, with the same final effect. If you've already germinated the seeds, and you don't have anywhere to plant them, then, by all means, you should experiment and see what happens if you try to keep them dormant in the fridge, you may well learn something important that could be of use to all of us! Please let us know how you get on. All the best, happy growing!


Sarah Packer 2019-08-19
My sister and I have heard about cannabis seeds and how beneficial they are, so I wanted tips and ideas on storing them once we get some. I didn't know cannabis seeds need low humidity and temperatures to be stored safely. I'll have to keep that in mind and ask the supplier if the seeds are safe to have around my dogs, thanks to this post!

Alchimia Staff

Tim Alchimia 2019-08-19
Hi Sarah, thanks for your comment. Low temperatures and low humidity are absolutely essential to seed conservation if you're keeping the seeds to grow, the best way is to vacuum pack them with some silica gel beads and store in a dark container in the fridge. If we're talking about hemp seeds for ingestion, then the same storage guides apply but we can be a little less rigorous as we aren't trying to store for long periods of time and preserve germination vigour, but usually storing short term before eating. I don't think you need to worry about the seeds being safe to have around dogs, there's no risk of any harm coming to animals if they should ingest some seeds, quite the opposite in fact (unless the animal should be unfortunate enough to choke on a seed, heaven forbid!), because cannabis seeds, like hemp seeds, are highly nutritious and contain a wide range of essential fatty omega acids, among other beneficial properties. If however, you want to feed them to your animals I'd recommend getting some cheap hemp seeds rather than the relatively more expensive cannabis seeds we sell for growing! I hope that helps, all the best and happy growing!


Thomas Jameson 2019-07-17
It's good to know that cannabis seeds need low moisture and temperature for their proper storage. My wife and I would like to grow some cannabis, so we'll need to properly store the seeds that we aren't using. We'll be sure to look further into our cool and dry storage options.
