How to prevent the death of cannabis seeds and seedlings
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.
Cannabis seeds must be stored in the correct conditions
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.
How do we store leftover seeds to grow at a later date?
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 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 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
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
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.

What To Do With Marijuana Seeds
When and if you find seeds in your flower, there are several options for utilizing them in ways that do not involve a trash can.
As cannabis consumers, you may occasionally find seeds in your bud due to hermaphroditism, stressed plants, light pollution, inexperienced growers, or just the luck of the draw. Before you call the dispensary and ask to speak with the manager to complain, relax. Don’t panic, either.
Seeds in your weed means that the buds have been pollinated — either from another male plant or from the plant’s own hermaphroditic male clusters (those dreaded banana-looking growths). When you buy feminized, autoflowering store-bought seeds, they are hand-selected and almost always better than random seeds found in bud by accident. This is because there are higher chances that the seeds will yield female end products. Regardless, when and if you find seeds in your flower, there are several options for utilizing them in ways that doesn’t involve a trash can.
Leading cannabis horticulturist Ed Rosenthal, who has grown and experimented with cannabis his whole life, was able to lend a hand. When we asked Rosenthal what the best course of action is in the event that you come across seeded cannabis, he told MERRY JANE, “Be sure to pick out all of the immature seeds. You don’t want to smoke those. And set aside the healthy mature seeds for later, which may be worth growing.”
The larger, darker, viable seeds are distinguished in appearance from the smaller, whitish, immature seeds, which are a little harder to find inside the bud. Seeded cannabis is generally lower quality than top-shelf sinsemilla, but it’s best used in edibles, says Rosenthal. This is because all seeds will be removed in the process anyways.
Now that you have picked out your seeds and separated them from the cannabis, there are a lot of different things you can do with them. Here are five ways novices can use leftover seeds.
Grow a Pot Plant
Why not test out your cultivation skills with a hobby plant grown in your window sill? While you shouldn’t expect a high yield, or even expert-level cannabis, experimenting with plants is fun. Look at master cannabis bonsai growers like Budzai or Bonsai Empire for inspiration. The possibilities are endless, and the stakes are low.
Spread a little love on your next hike in a hidden wooded area — Johnny Appleseed-style. Then, simply walk away. Let nature run its course from there! Who knows? You may start noticing flourishing wild patches of cannabis wherever you dropped them. Or, if you’re inclined, plant the seeds somewhere public, like a park, and see what happens. Just don’t take credit for this, as it’s likely a felony!
Return the Weed
Try to return the seeded weed at the dispensary. In almost every case, the budtender will say “no.” That would be like trying to return fruit at the grocery store. But seeded cannabis is weighed down by the seeds, making it lesser quality, so inform them of the sub-par cannabis and move forward.
Save Them and Eat Them
Can you eat cannabis seeds like hemp seeds? According to Quora, yes. They can be unshelled, shelled, or roasted. Like hemp seeds, there are some benefits, though not the same benefits as, say, an edible infused with THC and CBD. Rich in Omega -3 and Omega -6 fatty acids, eating seeds can help protect your brain. It may also help prevent mental health issues, dementia, or Alzheimer’s. Seeds are also rich in vitamins A, E, D and B, plus they are chock full of minerals like sodium, potassium, iron, zinc, and sulfur.
Sell Them (check local laws first. )
As a consumer there aren’t many ways to distinguish one cannabis seed from another. Reputable seed sources are trusted for their consistent quality, but buying seeds off the street is pretty much a no man’s land. Perhaps someone you know could use seeds for one purpose or another. Be careful, however, because the murky definition of the legality of cannabis seeds depends on what state you live in.
Ambitious Bonus Tip: Start a Seed Bank
Grab a journal like Gold Leaf’s grow planners, or take a more modern approach with a growing app like GrowBuddy. Those notebooks can be used for seed data, too. Jot down your notes, and store seeds according to the strain that you found them in. Mystery seeds are great for future experimentation!

Step Two: Germinating Marijuana Seeds and The Seedling Stage
December 31, 2018
Germinating marijuana seeds means “activating” the seed,. which is the first step to start growing your weed (or technically the second step after building your grow room ). The seed contains not just the embryo, but also the food that plant will use during its very early stages of life. When exposed to moisture and warmth, the seed will naturally “activate,” and begin using its stored food to develop a taproot and push up from the grow medium. In order to achieve successful germination and rapid early growth, it is crucial to maintain ideal conditions for your germinating seeds.
If you are new to growing cannabis, and would like some extra help germinating your cannabis seeds. Then check out this awesome video from Percys Grow Room . It will take you step by step through the germination process.
Where to get your cannabis seeds from? (Seed Banks That Ship to USA)
Marijuana seed can be obtained from many sources (online and offline), the quality and the and genetic diversity can vary based on where you’re getting cannabis seeds from. Online seed banks are your best bet if you’re not located in a region with recreational legalization established.
There are many reliable outlets sell high quality seeds, here is a list of The Best Online Seed Bank for Feminized Seeds that ship to the USA, in the industry. These seed banks have strong reputations and are known for providing high quality genetics.
If it’s your first time growing, it also pays to get feminized seeds. Dealing with identification and removal of males is an additional complication that inexperienced growers can avoid simply by purchasing feminized seeds.
The choice is always up to the grower, but I strongly believe feminized seeds are a justified expensive and recommend them for any new grower.
Mature Cannabis Seeds, This Is What You Need to Do
Once you get your marijuana seeds, you will want to check if they’re matured. If you use a good seed bank, like the ones in the list above, then you will most likely receive quality seeds that are ready to be germinated.
Matured marijuana seeds shell tends to be very hard, darker brown or deep tan, with lighter accents (stripes). If they look fresh and green, it means they didn’t reach full maturity, they’re pretty much useless .
How to Germinate Marijuana Seeds
Before you plant the seeds, you need to germinate your cannabis seeds, and to do so, you will need three main things; water, heat, and air, like every living being on earth. There are a few common methods for germinating seeds, and some seed banks provide detailed instructions for how to germinate the seeds you purchase from them. Some banks also provide a guarantee on germination rates, and will provide replacements or refunds, but only when their instructions have been followed.
Although we recognize a number of methods as being successful means to achieve germination, always follow your provider’s instructions when applicable, particularly so that you may take advantage of any guarantees included with your purchase.
Now, how to germinate marijuana seeds ; the following method (paper towel germination) is the most common, and one of the most simple. Here is what you need:
- Clean plate, and another one to be used as a cover (optional)
- Paper towels
- Marijuana Seeds
And here is the method:
- Soak 6 paper towels sheets in a distilled water.
- Take 3 of the soaked sheets and put them on the plate.
- Put the marijuana seeds on the soaked sheets, each seed should be an inch or more apart from the one next to it.
- Cover the marijuana seeds with the remaining 3 of the soaked sheets.
- Now, if you need to create a dark environment for the seeds, you can take another plate (the same size) and flip it over to cover the seeds/paper towel sandwich. This is not necessary if you have a dark place to put the seeds, such as a cabinet, drawer, closet, etc.
- Finally, as for how long to germinate marijuana seeds in paper towel: just give it some time. The germination period is different from one seed to another. Some seeds germinate quickly, others can take up to a week.
Check your germinating marijuana seeds at least once a day. You will probably need to add more distilled water as they begin to dry out. You don’t need to completely drenched the paper towel, but it should always be damp to the touch. Once the seeds split, you will see a single taproot coming out (see the picture below). You will know that your beloved cannabis seeds are successfully germinated.
Once the tap root is approximately 0.25-0.75 inches (0.6-2.0 cm) it’s time to move them into a starter medium (rockwool cube, peat moss plug, etc.) or soil and straight to your grow room.
Important tips to ensure successful germination for the marijuana seeds:
- Keep the seeds in a warm environment, between 70-77°F. High humidity is also preferable; germination rates tend to be higher at around 70-80% RH.
- Make sure to keep the paper towels sheets soaked all the time. If them seem like they’re getting dry, simply add some distilled water to keep the sheets saturated.
- Open the plate’s only once a day to check the progress.
- As the seeds begin to split, do not, I repeat, DO NOT touch the seeds or the tap root. It’s very important to keep this area clean and sterile.When you are ready to transplant them to the medium, use sterilized tweezers if possible.
Moving Your Germinated Seed to A Pot
Due to the limited root system the germinated seeds have, best practice is to plant the germinated seeds in small containers. This will increase the plants’ accessibility to oxygen and nutrients by avoiding overwatering.
When plants are initially placed in large pots, they cannot use all of the water and nutrients around them very quickly. This results in damp conditions that facilitate the growth of mold and certain pests. Thus, we prefer to start our seedlings in small containers like solo cups, then transport them to a bigger container when they start developing a larger root system (once they hit the seedling stage).
Here is what you need to do:
- Acquire a small 2 inch pot (or solo cup) for each germinated seed
- The soil you will be putting in the pot shouldn’t be dense. It has to be rather loose and airy. You generally want a mixture of potting soil and perlite, roughly 70:30 to 50:50.
- Dig a hole approximately 0.5 inches, or one knuckle deep, in the middle of the pot using a pen, and drop the germinated seed in it ( tap root faces down ). Make sure to transfer the germinated seed gently and carefully, I usually avoid using my hands to move the seeds; a pair of tweezers would do the job.
- Lightly cover the hole/seed with soil (enough to block the light without obstructing the seedling when it emerges).
- Now, add a little bit of water. Make sure the soil still covers the seed after watering it. Not much water is necessary, and you shouldn’t need to water again until after the seedling emerges.
Final Steps – Marijuana Plant Seedling Stage
Place the small pot(s) in your grow room, and turn the lights on. The seeds technically don’t need the light at this point, but they immediately do once they pop out of the soil. Having the light on and waiting for the plant will assist the young plant to develop better and faster. You can leave a fluorescent light close to the surface (a couple of inches away) from the plant since fluorescent lights don’t emit a lot of heat, but HID or LED should be at least 24 inches away, if not further. Refer to the light manufacturer’s instructions to see if they provide a recommendation for distance from the canopy at various stages of growth.
Here are a few other things to keep in mind for germinating your seeds:
- The temperature should be around 73 F at all times . Warmer temps will not cause any problems, at least until closer to 90 F. Cooler temps, however, can stunt growth in early stages.
- Humidity should be around 60-70% RH.
- When you water the pots where you planted your seeds, you want to make sure giving them just the right amount of water without over saturating the soil, which may cause suffocating the sprouts and kill it. Using a spray bottle can do the job; they do not need much water early on..
- Make sure your pots have holes in the bottom to allow water to drain.
- Do not overwater! It is really easy to overwater and cause severe stunting or even kill the seedlings. If you can feel any moisture at all when you touch the soil, they do not need water yet.
- In 3 to 7 days, you should start seeing the first signs of your newly born cannabis plant.
- Once you see the first sprouts; have your fluorescent lamp running 18 hours on, 6hours off in 24 hour intervals.
- In 3 to 4 weeks, the cannabis plant should be around 4 inches high, which is big enough to be moved to a bigger pot; this is the true start of The Vegetative Stage ! If you are using a solo cup, the plant’s fan leaves should now be stretching over the edges of the cup. This is a good indicator that you are ready to move up to a larger pot.
