What Does it Mean to Germinate Cannabis Seeds?
Germination is the natural process by which a particular organism grows from a spore or seed. In this case, the term is referring to the sprouting of a cannabis seedling from a seed , which can be encouraged by help from the cannabis grower. Germinating your seed is the first crucial step in the cannabis growing process, and it can be surprisingly simple with the right tools. Even though the process of getting a seed to sprout and bear a healthy plant is a challenge for some growers, it doesn’t have to be when you start with a grow kit from a Pot for Pot. With our help, your plant will sprout and start growing in no time!
What to Understand About Germination and Endosperm
The first thing to understand is that seeds come naturally equipped with their own starting food- endosperm. It plays an essential role in ensuring your plant reaches its full potential. As a seed begins to sprout, this starchy blanket around the embryo provides nutrients to a growing plant. If it doesn’t seem like a lot, don’t be fooled- there’s enough starch there to feed humans.
That starch is only part of what you’ll need, however. You’ll also need to provide specific temperatures to germinate your seeds. Ideally, you’ll want to keep the temperature around 25 degrees Celsius (77 F) for the best results.
What Happens During Germination?
The process of germination is when plants start to sprout from their seeds, and it’s relatively the same throughout the plant kingdom. A little bit of moisture makes the tiny plant inside crack open its outer shell and sprout upwards while pushing its root downwards. Once it’s cracked through the shell, you’ll need to give your little babies a bit of water and some love for the fun to begin.
Your seeds will need the right conditions to break through their shell and continue to grow, however. Otherwise, they may take longer to germinate. Our seedling starter kit can help you create those perfect conditions. It makes sure your seed has just the right amount of water (so that it stays moist, but not too wet). Once it has germinated and grown enough to sprout its third set of leaves, simply move your young plant into the a Pot for Pot fabric pot for continued healthy growth.
It’s best to germinate seeds indoors where you can better control the temperature. Seeds are more likely to sprout in a warm and stable environment.
How to Sprout Marijuana Seeds
Marijuana plants start as a seed . That tiny thing resembling a pebble is a whole plant securely stored with a supply of food to support itself for a few days. In the germination process, the food converts into sugars, which the plant uses to cut the shell and develop its root. Identifying a healthy seed is, therefore, the first thing that you need to do.
The sprouting process is the foundation of your marijuana plant, so do not take this step lightly. Other than starting with a high-quality seed, you need to ensure that your conditions are optimal. It is challenging to optimize the natural mediums, which is why a medium such as Jiffy Pellets comes in handy.
Different Ways to Germinate
There are many ways to germinate seeds, but we recommend using peat pellets. Not only is it the safest way to start your seeds, but it’s also the easiest. Jiffy is hands down one of the best brands of peat pellets on the market , and if you are thinking about germinating using peat pellets, this is the way to go. This method is great for avoiding the risk of damaging new roots. We’ll get into more detail about the wonders of Jiffy Pellets in a later section of this article. But first, let’s explore the benefit of peat pellets in general, along with some other mediums growers can use to facilitate effective cannabis germination.
Peat pellets are comprised of decomposed vegetable matter which your plants will absolutely love. When you add water, it expands, creating a nutrient-dense medium that is a good replacement for soil. When the roots are visible, you can transport the whole pellet into a Top Soil mix with fortified a Pot for Pot Superb Soil so it can continue developing without accidentally causing root damage.
Basic Mediums for Marijuana Germination
There are many different germination methods, and results will vary. Here are some basic ways to sprout your seeds :
Sprouting marijuana seeds in regular soil is a common practice. Soil is a natural medium and can protect the seeds as they develop their fragile roots. For this option, be sure to start with the right type of soil for marijuana. Use a seed starter or fertilized potting soil with a pH of around 6- 6.5. Soil has both minerals and spores that support growing marijuana plants. Soil can have too many nutrients for fragile seeds so take care when doing this method that your soil isn’t too hot.
Water is another method for sprouting a marijuana seed. Soak seeds in a cup of water in a dark place for 24 to 48 hours. Plant after 48 hours whether or not the seed has sprouted a tail or not. The advantage of using water is that you can ensure adequate moisture for germination. The plant will also have an easier time breaking its shell compared to when it is in a soil medium. It is really important that your water is chlorine free and ideally pH neutral to slightly acid. (with a pH of 6.5- 7.0)
This mineral wool comes from volcanic rock and other materials such as limestone and basalt. To make this material, the ingredients are heated into molten lava and rapidly spun into threads. These threads then undergo compaction, curing, and finally, cutting.
While Rockwool is a suitable environment for germination, you’ll need to adjust it a bit for growing marijuana. First, you’ll need to add fertilizers- around 600 parts per million. You’ll also need to reduce the pH, which is too high to support sprouting. It’s also a bit dangerous to use, so please wear gloves and protect your mouth and eyes while handling it.

The Best Marijuana Germination Medium: What to Know About Jiffy Pellets
For the best results, you need a precise understanding of how to get started growing your marijuana plant. As stated a few sections above in this article, choosing Jiffy Pellets as your initial medium is probably the best way to go. Every a Pot for Pot kit includes a Jiffy Pellet, so you don’t need to worry about purchasing it separately, and if you run out, you can order some refills or one of our expansion kits .
What is a Jiffy Pellet and How Does it Work?
A Jiffy Pellet is a natural, biodegradable growing medium conveniently available as little compact discs that help sprout seeds into seedlings. Jiffy Pellet composition includes peat moss, a mesh, and other ingredients such as lime, fertilizer, and ammonium to help seedlings grow.
Jiffy Pellets are both a container and a potting mix for sprouting seeds. Peat moss is a medium that’s rich in organic materials, and the mesh securely holds the peat moss in place. Using Jiffy peat pellets either indoors or outdoors is an effective method to grow healthy and robust marijuana plants.
To use a Jiffy pellet, water it first. Then, place your marijuana seed a bit below the surface level. When the plant is strong enough, transplant the entire pellet to a larger pot.
What are Jiffy Pellets Composed of?
To help you better understand the advantages that Jiffy Pellets can provide to your seed germination efforts, let’s take a moment to explore the various beneficial components they contain and how they work to benefit your plants.
Technically, a Jiffy peat pellet is a small disc made of compressed material. However, Jiffy pellets enlarge up to seven times their original size when you add water , creating a suitable environment for the sprouting process. The fine netting keeps the Jiffy pellet ingredients in one place as your seed sprouts. Said ingredients include:
Peat is an organic medium that provides plenty of nutrients for sprouting seeds. It is made from sphagnum peat moss, which has a high water-holding capacity as a result of its fluffy and light texture. Peat provides excellent root aeration, making it easy for roots to grow without interference.
Lime, Ammonium, and Fertilizer
Jiffy pellets are primarily made from peat moss. However, peat moss on its own is not ideal for sprouting seeds. That’s why they also include lime, which raises the pH of the medium. Jiffy Pellets have a pH of 5.5, compared to peat moss’s 4.4.
Jiffy Pellets also include fertilizer that provides seedlings with all their required nutrients for the first 1-2 weeks. You won’t need to add anything else as your seed sprouts. After transplanting, you can apply fertilizer, if desired.
How Big are Jiffy Pellets?
Jiffy pellets come in diameters of 24 mm, 33 mm, 41 mm, and 70 mm. The sizes vary to cater to the various needs of different seedlings. The larger Jiffy Pellet sizes are convenient to handle and are ideal for marijuana.
How to Germinate With Jiffy
Jiffy pellet instructions are easy to follow and will take you less than 20 minutes to set up, ensuring you’ll be able to start your cannabis seed germination project quickly and easily without wasted time or effort.
Choose Your Container
The first step is to place your pellets in a container. Ideally, you can use a Jiffy pellet tray. Ensure they do not overlap and leave a small border for water retention.
Water Your Jiffy Pellets
You can use tap water or distilled water. Keep in mind, tap water may have chlorine, which is harmful to your plant and can cause it to dry out faster. However, you don’t have to buy distilled water to prevent chlorine problems. Evaporate the chlorine by pouring your water, and let it rest for some time. Use very warm water, around 95oF, to help the pellet expand faster.
Plant Your Weed Seeds in the Jiffy Pellets
Place the seed in the middle of the enlarged pellet. Don’t place the seed too deep, or it will not sprout.
Cover Your Seeds
To avoid moisture loss, use a plastic cover – this usually comes with the pellets. You can also use plastic wrap. If you don’t have a Jiffy pellet dome, you will need to water again after around seven days. Avoid dropping water from the top; otherwise, you will disturb the developing seeds.
Transplant Your Plant into Some Soil
The seeds are usually ready for transplanting after two weeks. To do this, simply make a hole in the soil and place your pellet directly in that spot.
An Alternative to Jiffy Pellets to Consider
Coir is a popular alternative to Jiffy pellets , with Coconut Coir leading the trend. This material is made from coconut husks. If you choose this medium, use a coir Jiffy Pellet tray to hold it. Coir has water retention capacities similar to peat, but not as good, and it is more airy which means you will want to water it more often and make sure it is compact.
Coir also repels insects and is reusable , so it can help you if you choose to expand your growing operations to include more cannabis plants.
What to do After Germination
After your seeds have germinated, they need to go into a pellet so the roots can spread out and grow. You may be wondering just how far in the jiffy pellet the seeds should be planted once it has germinated. You’ll want to drop the seed about a half-inch to an inch. If the seed has not sprouted, it’s okay to place it in the jiffy pellet – as long as it has soaked for at least 12 hours, but no more than 24 hours. If it has sprouted, drop the white root downward, so that the head of the seed is about an inch below the surface.
Damping-Off With Hydrogen Peroxide
Once your seed becomes a tiny plant, it’s now known as a seedling. This is great, except that seedlings are very delicate. You’ll want to be on the lookout for the number one seedling killer: damping off. Damping-off occurs when something (such as fungi or other diseases) causes the nutrients in your plant to stop being transported properly. The stem becomes mushy and falls over, and your plants will die young. The risk increases when there is minimal direct sunlight and air circulation, combined with warm temperatures and high humidity.
Eventually, your plant will be able to protect itself, but until then hydrogen peroxide is an excellent solution to this problem before it can begin. Hydrogen peroxide provides oxygen to the soil and reduces the chances of fungus spores developing.
To effectively prevent damping off, combine 1 tsp. of hydrogen peroxide with 2 cups of water. Use this solution to water the plants. Or you can soak the seed in 1% hydrogen peroxide before planting.

Germinating seeds safely
You can find different methods to germinate seeds of marijuana of sure form, but the primordial thing to consider is the temperature of the place where they are going to germinate, since the ambient temperature is what is going to guarantee the success of a harvest, since so much by excess or by defect, your varieties of marijuana can suffer the variations, therefore the best thing is to contribute a stable environment, watching that the seeds are between the 26ºC and 27ºC.
To germinate seeds of marijuana securely, put to soak your seeds of marijuana a few hours before, and in a tupper, places a base of wet napkins, without they get to soak, distribute the seeds above and cover them with other napkins in the same way. Close the tupper and place it on a heat source that does not become very high, an electronic device for example, and that does not receive much light. After a day or two, when you see that the root begins to emerge, you can pass them very carefully to a small pot.
For your seed plantation to be effective, you have to follow a series of steps, obviously, as with all plants, you have to provide them with water, to which you can add oxygenated water, which has anti-fungal properties and helps the water have more oxygen. Then you have to decide where you want the germination to take place, and make sure that the environment and temperature of the place is the right one
⭐ How to germinate marijuana seeds in an easy and homemade way?
A very easy and useful process, is to put the seeds in a glass of water and let them rest until you see that the root begins to come out, when this happens and very carefully, you can transplant them without introducing them very deep into the ground, allowing them to come to light.
How to germinate marijuana seeds in propagators?
- There are some discs of pressed peat where the seeds can be germinated and it is one of the most used means.
- In first place it is necessary to moisten the seeds in water, better if it is bottled, because the one of the tap contains lime that can spoil the seeds and let rest in a dark place during 48 – 72 hours until they throw the root.
- Hydrate the germinators with mineral water and wait for them to swell, then make a small hole and put the root, leaving the head of the seed flush..
- To maintain the humidified seeds, to a temperature of between 21ºc and 23ºC and under a powerful light..
- To germinate seeds of marijuana in flowerpot, is another of the methods used at the time of germinating your roots, since it makes that the phenomenon known as gravitropismo takes place, that makes that in addition to growing to a more accelerated rhythm, causes the basipetal growth of the roots and that the leaves of the plant grow upwards
- Leave the seeds to soak for at least 12 hours to properly hydrate the shell and sterilize the soil with quality substrates such as worm humus.
- You should put one seed per pot, so that they do not get in the way, moisten the soil and introduce the roots. Leave the pots in a warm and dark place until you see that the plant begins to emerge, at which point you can place it in the light..
- A very habitual practice between the Cannalovers, it is to conserve seeds of marijuana, in a box of conservation like for example the Box 00 Box, and later passed a time to germinate them, they are the known commonly as “old marijuana”, but it is necessary to take into account certain aspects before you begin the culture.
- If you’ve been careful about saving the seeds, you shouldn’t have any problems. I always use the 00 Box, which, with its humidity control, provides an unparalleled conservation habitat.
- -You will also have more options to germinate if the seeds do not have more than a year and a half, from that time, the shell is hardening and the chances of the root coming out dive.
In this video you can see how one of our experts gives you some basic tips on how to germinate your marijuana seeds
When is the best time to germinate marijuana seeds?
The best time to germinate marijuana seeds is spring. The temperature is warm but without being exaggerated, avoiding that your plants suffer an excess of light and heat that spoils them. In spite of it, if we have precaution, we can germinate seeds throughout the year.
Time of germination of seeds of marijuana
The time of germination of the seeds of marijuana, can be faster or less. It varies in function of many aspects, temperature, environment, genetics and age of the seed, method that you use for the germination, humidity, light, etc.
The seeds of marijuana can take to germinate, between 2 or 10 days, alone you must have patience and to watch that the conditions of the seed are the suitable ones, see, it is humidified and in a dark place.
✨ What are the different ways to germinate? Which is the best?
First, I’m going to do a review of the basic conditions that we must meet before we begin to germinate your marijuana seeds. The first condition to take into account to germinate your marijuana seeds, is to provide humidity, that is to say, water. This can come from the tap as long as its EC does not surpass 1, in addition its PH will have to be placed in a value near the 6, with a suitable temperature of approximately 22 degrees.
Later you must choose the method with which you want to germinate your seeds, which can be:
– To germinate seeds of marijuana by means of Jiffy o or Presses of Peat.
They are dehydrated and pressed peat tablets, are left to soak until they become a bag full of substrate. There are different sizes and coconut fiber instead of peat, and its main characteristic is that it retains a large amount of water, so during germination you should not water again.
– To germinate seeds of cannabis by means of Cubes of Wool of Rock.
If you opt for a hydroponic cultivation, no doubt germinate marijuana seeds in cubes of rock wool, is your best option, as they do not dirty the cultivation system and the seeds germinate very fast with this method. It dries very quickly, so you will have to constantly monitor the humidity.
– To germinate seeds of cannabis with Napkins of Paper.
This system is the most used by all to germinate marijuana seeds, especially because it is the cheapest and simplest. It simply consists of placing kitchen paper on a container such as a plate and humidify it, the more kitchen paper you put, the greater the humidity will be retained and less will have to hydrate later.
Once moistened, the seeds are placed on top and covered with another plate leaving space between them so that the seed breathes well. You have to keep in mind, that never ever the paper dries, so you have to be aware of the humidity.
– Germinate marijuana seeds with Propagation Tacos Rootit
The Rootit propagation blocks are like small sponges so that the seed takes root well. They are totally biodegradable. Their use is similar to rock wool taco.
How to germinate marijuana seeds in soil?
Germinate marijuana seeds in soil, is the method most used by the vast majority of growers, especially among growers who are not professionally engaged in growing cannabis. I am going to give you a series of advices and indications, so that you can germinate your seeds of marijuana in ground, without making mistakes and is everything a success.
- Control the PH of the water and of the earth, with specific apparatuses for the measurement of the PH.
- Prepare all the material before starting, Don’t forget anything! You must have all the fertilizers and fertilizers you will need prepared.
- Analyze your climate and the characteristics of your seeds, it is very important that you choose well. Because, you must know perfectly the characteristics of your seed, in order to get the best out of it.
If you use mother earth to germinate your marijuana seeds, you will obtain many better results, and if you place it in the zone of the suitable garden where it receives the hours of light that they need to grow strong and healthy, you will obtain a much greater productivity.
The most commonly used method of germinating is soil.
How to germinate with coconut fiber?
Germinating marijuana seeds with coconut fiber, is very effective thanks to the oxygenation capacity of the coconut, which helps a lot to the development of the roots, getting to obtain a 90% germination level. We are going to go step by step:
- It works well the coconut fiber with the hands, so that not even a single compaction remains, to later place it in the flowerpot where we are going to make the germination.
- Hydrate the coconut fibre very well, with quality water.
- Once well hydrated, make a hole of no more than 1 cm to place the seed.
- Cover the seed well, and add a couple of drops of water.
Now simply maintain a good hydration and stable temperature, leaving nature to run its course. The fundamental advantages of coconut substrate, is that they allow a greater root growth than other types of substrates, and collect moisture very well, your seeds will grow and become larger plants and therefore with higher levels of productivity.
How to germinate with jiffys?
To germinate seeds of cannabis with Jiffys is one of the most effective methods, and with more rate of success of all. The Jiffys or pressed peat are some germinators that are introduced in a hermetic receptacle and they are humidified until they reach their complete size, next a small hole is made in the center and the root of the seed is introduced that previously we will have left in soak during 24 hours in a glass of mineral water, that contains a PH of 6,5 to a temperature of approximately 20 degrees. This step is not essential, but it helps the seed to open more easily afterwards.
Then we must cover the container and let it rest in a dark place and at a warm temperature.
Jiffy or Peat Presses retains a large amount of water
Toilet paper, napkins?
Without a doubt, to germinate seeds of marijuana in hygienic paper will not be possible, since the hygienic paper is designed to dissolve to the contact with the water and not to block the pipes of house, whereas the kitchen paper, is designed to absorb the greater amount of water possible, and this is what will cause that your seeds of marijuana germinate correctly..
Ah! I forgot, always bear in mind when you start the germination of your marijuana seeds with blotting paper, place 30% more of the seeds you want to germinate, because these methods are not infallible and some may not germinate.
Do we use a tupper?
The answer is yes! germinate marijuana seeds in a tupper, it will help you to conserve the humidity of the napkins where we have placed the seeds and in addition it will maintain safe in an environment where the temperature can be controlled much better than if you use a plate. In winter remember that it will be ideal, if you place the tupper on top of the TV, and you will get a pleasant interior temperature of about 20 degrees.
How to germinate with alcohol?
The use of alcohol to germinate marijuana seeds, can lead to the seeds die or burn, it is much better method to use oxygenated water where we will soak them, this will provide the seeds more nutrients and oxygen and will help in their growth
How to germinate in cotton?
To germinate your seeds of marijuana in cotton, has a procedure that is basically the same as in humid napkins, the only difference is that it is not necessary to cover the seeds above with another layer of humidified cotton, of this way, although they are in a closed receptacle, it is not necessary to open it neither to remove the layer of above to see if the roots of our plants have begun to leave, which is more favorable at the moment of allowing them to sprout.
To germinate with light or without light?
To germinate your marijuana seeds, it is necessary that they are in the dark, and once the roots have begun to sprout it is time to finish the process of germination of your marijuana seeds placing your plants under the light of the sun or under the focuses of your indoor culture, but until then, the plantation must remain in a closed and covered container and in a dark and humid place.
To germinate your marijuana seeds, it is necessary that they are in the dark
How to germinate with water?
Another of the methods to germinate your marijuana seeds, is using a glass of water, much more comfortable and easy to manipulate that to germinate your marijuana seeds in plate. You must place it in a temperate and dark place between 20-22 degrees, adjusting the PH of the water between 6,0 and 6,5 and later the seeds are sowed. You will have to change this water every 24 hours, or to throw a drop of oxygenated water to avoid that it rots
During the initial process of the germination of your seeds of marijuana in jar with water, these will float on the same one, but as soon as they begin to open between 24 and 72 hours, they will precipitate to the bottom. Once it has appeared already the root, it takes out of the water the cotton or the napkins, and plant them in the flowerpot to a depth of 0,5 to 1 cm.
Remember, that to germinate your seeds of marijuana in water, it is necessary that you use mineral water, although if the water of the faucet of your zone fulfills the requirements of PH you can use it also, but for quality I remain with the mineral water.
Why use hydrogen peroxide?
Using hydrogen peroxide in the process of germination of your cannabis seeds, brings benefits widely demonstrated and I’m going to detail. In the first place, in the case of opting for a germination of your seeds with water in jar, to contribute a drop of oxygenated water to him, avoids that the water rots, and it is necessary to change it every 24 hours. It also eliminates fungi and bacteria thanks to its anti-fungal properties, if you choose to pour water from the tap.
Adding a drop of hydrogen peroxide eliminates fungus and bacteria.
How to germinate with autoflowering seeds?
The autoflowering seeds, are the most cultivated varieties of the moment, especially for the short periods of flowering, and the strength that they present in front of their feminized sisters, and in times in which speed and time dominates our lives, they are acquiring an important notoriety.
Their germination process is identical to that of feminised or regular seeds, so you won’t have to do anything different.
✅ How to germinate marijuana seeds fast step by step
Below we are going to see a daily monitoring of the germination of marijuana seeds between napkins, since from our point of view it is the fastest and safest way. Let’s see a couple of tricks that speed up the process and greatly increase the chances of success:
- We recommend germinating the seeds inside a heated propagator or greenhouse, if possible with a temperature of around 25º C. (This is a slightly higher temperature than recommended, but this accelerates the activation of the germ) and a humidity around 90%.
- We place a plate inside the greenhouse, put a napkin or kitchen paper on top of the plate, put the seeds on the napkin (Separated at least 2 cm between them so that the roots do not get entangled)
- We put another napkin on the seeds and now we have to moisten the whole with a nutrient solution that contains water, root stimulator, and 2 drops of hydrogen peroxide. (It can be moistened with water only, but this mixture accelerates germination and hydrogen peroxide also acts as a disinfectant) Moistening does not mean soaking, in the case of excessive humidity, the ideal would be to wring the napkins a little.
- We close the propagator or greenhouse with its lid and leave its openings or windows closed to maintain humidity and heat, we introduce a thermo-hygrometer or its probe, and we plug the cable into the network to activate the heating.
- From this moment the germination phase of the seeds begins, and you will say, How long does it take for a marijuana seed to germinate? It can last between 2 and 10 days, but as a general rule commercial seeds usually need between 3 and 6 days. It is recommended to open the greenhouse every day to check the condition of the seeds, and in passing we will check the humidity of the napkins in case it is necessary to moisten again.
- Day 1: After approximately 24 hours we can open the greenhouse and carefully separate the napkin located at the top, and I say carefully because some seeds may stick or fall. The first day of the germination phase, as a general rule, hardly any changes will be seen, but if you look closely, some seeds will have acquired a darker tone, it is the sign that they are beginning to hydrate. Other seeds will look exactly the same as before they were put to germinate, because the shell that covers them can be different thicknesses, and those that are very thick take more time for moisture to penetrate.
- Day 2: We opened the greenhouse and the whole to check the condition of the seeds, and the normal thing will be that those seeds that had not begun to hydrate, now look darker, and those that looked darker yesterday, today will be a little bigger, and if you look closely you will see that they start to open a little. The seeds have an oval shape, and if you look at their ends you will see that one of them ends up in a more pointed shape than the other, and that’s where they start to open.
- Day 3: When you open the greenhouse you may notice less humidity than the previous days, and you may have to moisten the napkins. Keep in mind that by maintaining a moderately high temperature (approx. 25º C) the humidity evaporates more easily, but it is really worth it because you can save several days of germination. Those seeds that had begun to open yesterday, today already show the tip of the primary root showing, and you have 2 options, sow them in the substrate now or wait for more roots to show. The writer of this likes to wait until at least 1 cm of root is visible to pass it to the substrate, but there are also people who prefer to wait until they see 2 cm or more. It is advisable to take the seeds with tweezers without touching the root, and remember that the seeds are buried in the substrate with the root facing downwards, at a depth of between half a cm and approximately 2 cm, and it is recommended to water with root stimulator and microlife without soaking the substrate. The seeds that yesterday had barely begun to hydrate, today we can see them larger and already opening, so we leave them germinating, close everything and continue waiting.
- Day 4: We reopen everything to see the state of the seeds, and at this time the most normal thing is that all of them have already hydrated, and those that have not done so may never do so. The small ones usually germinate before the big ones, especially because of the thickness of their shell. If you have large seeds that after 4 or 5 days of germination continue without signs of hydration, you can try a trick that helps in these cases, which is to crack the seedwith your teeth as is usually done to open a sunflower seed. The seeds that have already taken root can be sown just like we did with the first ones, and the first few days in the substrate it is advisable to keep the humidity between 80% and 90%, so it may be a good idea to put the pots in the same greenhouse.
- Day 5: The germinated seeds that we planted in the ground 2 days ago begin to sprout from the ground showing their cotyledons, and from this moment it is crucial to put them under light so that they do not sprout. The ideal is that the first day the light is located at a distance of about 1 meter, the second day at 60 or 70 cm, and from the third we will bring the light source as close as possible as long as it does not exceed 24 or 25º C. We check the state of the napkins to make sure they are not dry or too wet, and we look at the seeds to sow those that have already taken root. Some seeds never germinate, since their viability depends on many factors such as age, conservation, germination method, or even the genetics of the plants, since degeneration influences germination power.
- Day 6: The seedlings that have sprouted from the substrate will be watered with root stimulator and microlife every day or every 2 days, carefully moistening the substrate around the stem but without wetting the entire surface of the pot. Like every day, the germinated seeds that can be transplanted into the substrate are sown, and the rest are left to germinate. We review the data to verify that the humidity and temperature continue in the ideal parameters.
- Day 7: If there are seeds that have not shown signs of hydration, it is very possible that they are not viable and will no longer germinate, because in some cases the embryo stops being dormant due to different problems. However, you can keep trying for a few more days, but as I said before, the vast majority of commercial marijuana seeds need between 3 and 6 days to germinate correctly. Normally, after 7 days this phase can be concluded, since most of the seeds will have germinated and will already be growing, so it is possible to move on to the vegetative growth phase.
Is there any difference according to the strain?
The germination of seeds of marijuana, is the same independently of the race, it will only vary the period of germination that has each variety, but the processes or methods of germination, are all universal, although some of them as we have seen above, they are specially indicated for certain type of culture, because it is where greater yield obtains.
How to use the lunar calendar to germinate my seeds?
For thousands of years the human being, used the different phases of the moon, for agriculture, and today the lunar calendar, is very important to be able to get the highest possible yield from your cannabis plants.
The phases of the moon can exercise a different force based on its position, in many aspects of life, including the cultivation of marijuana and all its stages, including the germination of cannabis seeds
The ideal lunar phase to germinate your marijuana seeds according to the lunar calendar, is the Fourth Increasing phase. During this stage the moon increases the power of its rays, to which the plants respond with increased foliage and root. The end of this stage is the perfect one to germinate your seeds, thus you will begin to plant it the first day of full moon.
We have an application of the lunar calendar that you can download HERE. With it you will know which is the best time to germinate and perform any action related to the crop
⛳ What to do if our seeds do not germinate?
If your seeds do not germinate, it can be the result of several badly executed actions, such as abusively moistening the seeds, or having the temperature above or below what is necessary. It is also possible that the seeds used were not prepared for planting. When these cases occur, we must start again with other seeds.
Remember that if you buy them at PevGrow, we guarantee germination (here more information). If they do not germinate and you have used a suitable method, simply return them to us in the original package and we will replace them immediately.
What to do after germinating?
When your marijuana plant has already germinated, you must pass it already to plantation. Be patient, because during the first week you will see practically no progress, but from then on, the events shoot at a crazy speed.
Is there a difference between winter and summer?
Evidently yes, to germinate your seeds of marijuana in summer, is the logical thing especially if you opt for a culture of outside, since the seeds of marijuana need to have a warm climate and a good dose of solar light, to be able to grow strong and vigorous.
It is always more advisable to start planting well into spring, as temperatures are ideal for the seeds to grab and can deliver their best version.
Also exists the possibility of germinating your seeds of marijuana in winter but for it they are necessary the greenhouses, or that during this epoch, you opt for cultivating your seeds of marijuana in cultures of interior.
All these rooting systems can be purchased in your trusted Grow shop and do your own tests to see which method works best for you personally, since as we have indicated only three of the forms of germination of cannabis seeds … and as they say out there, “every teacher has his booklet”. ?

Like almost everything else about growing excellent Cannabis, germinating your seeds successfully is pretty simple. We’ve used this very basic, inexpensive method for many years and have shared it among thousands of growers worldwide who have all had excellent results with no issues.
First make a mix in the ratio of 1/3 3% hydrogen peroxide to 2/3 distilled water.
It’s important to use only distilled water – some of the common chemicals in tap water can stunt, warp or kill your plant even well past seedling stage when you’ve already spent weeks tending it.
Then soak your seeds in the distilled water/hydrogen peroxide mixture overnight. If you’re growing multiple varieties, be sure to soak them separately. (Don’t laugh. It’s happened.)
Next, pour some of the soak water onto really absorbent paper towels, then wring or squeeze them out lightly and lay them flat. We use 2-3 towels layered together to make a nice thick absorbent nest.
The best seeds often sink and compromised seeds sometimes float, but there are always exceptions to the rule.
Then sprinkle the soaked seeds, using a clean spoon or gloved fingers, onto the moist paper towels, not crowding the seeds.
Then fold the moistened towels over the seeds to make a flat little package.
If you’re sprouting more than 12 seeds at a time, make more than one package – don’t crowd them.
Then put the moist towel and seeds flat inside a closed, unzipped storage-size plastic baggie, laying it flat somewhere away from direct light at room temperature.
In two or three days the seeds will sprout – maybe not all at once, but that’s not a problem because within 24 hours of the first seed sprouting all the others will have sprouted too. Keep your inspection peeks short as not to dehydrate the paper towel.
When the seeds each have a 3/4” root and the halves of the shell are beginning to open noticeably, meaning the embryo leaves are swelling inside, they’re ready.
You then want to move each sprouted seed into a Jiffy Cube you’ve prepared by making a small hole using a pencil or chopstick. Again – be sure you used distilled water to hydrate your Jiffy Cubes and of course use it everywhere else during germination.
Replanted into Jiffys:
Using your fingers, pick up the seed very gently by its shell, and avoid touching the sprouting root as you transfer it into the jiffy cube.
Also remember what’s unfolding inside that little shell as you handle it, be super delicate and stay conscious of the life emerging inside.
Now place the sprouting seed root-down in the hole letting it settle in naturally with the top of the seed even with the top of the hole – never push it down.
If it doesn’t nest right in, lift it out and poke the hole a little deeper. The cells at the tip of that little root hold the most miraculous ecosystem of emerging life one can imagine and while they are incredibly tough in nature they are also vulnerable to our mis-handling.
Now all you have to do is let the new sprouts do their thing they do so well, with a little help from their friends. With a day or so they will raise up their first leaves. Keep them lightly misted if you’re in a dry environment but don’t over-do it.
In a couple of days when they’ve developed their first set of true leaves, not the embryo leaves, it’s time to put them into larger pots with living soil and a mild fertilizer and then let the plants fully establish themselves.

Is using distilled water really important for germination?
Using distilled water is probably the most important part of the germination process because well water, tap water, bottled water and even rainwater contain traces of contaminants that can inhibit germination and later vegetative growth and flowering.
High chlorine in tap water, herbicides in well water, phthalates in bottled water, as well as many other kinds of common water contaminants can kill or damage germinating seeds and will definitely affect your plant’s health, yield and flower quality.
Can I remove these contaminants with a garden hose filter?
Yes most of them you can. There are a variety of relatively inexpensive filters that screw onto the end of the garden hose that you use to fill containers and water your plants. Some have replaceable screens, while others use granular activated charcoal.
There are also screw-on systems with carbon block filters that run $20-$30 and are very effective at reducing chlorine and chloramine, and at removing pesticides, heavy metals, and herbicides.
What’s some of the science behind using Hydrogen Peroxide for germination?
Here are two core articles from the PubMed database:
