Germinate marijuana seeds
The seeds should also be kept in a dark place while this germination process is in the works. If all goes well, it should never take longer than 5 days for this process to occur. What you also need to know is that not all weed seeds will germinate. Some may just be dead ducks in the water. You can usually tell if a seed is healthy by examining in.

How Long Does It Take To Germinate Marijuana Seeds

If you have considered growing your own pot plant, you might have heard about germination. Yes, the germination of marijuana seeds is essential to any grower’s success. You cannot grow a weed plant without first germinating the seeds.

So, how long does it take to germinate marijuana seeds? Usually, it should not take more than 5 days for the germination process to happen from start to finish, and there are various methods you can use to do this which we cover on this article to help you.

What Is Seed Germination?

Ok, so the important thing to remember here is that you do need to germinate your weed seeds before you can plant them and start growing a plant. You cannot just stick a marijuana seed in dirt and expect it to start growing.

Now, germination is the process in which the food which the seed has stored inside of it is converted into sugars, so that the interior can begin to grow break through the shell of the seed and begin sprouting roots, the root system which your plant will need to grow.

A marijuana seed requires water to be applied to it in order to bring it out of its dormant state and begin its growth process.

Once you add moisture to the equation, the seed will break open and increase its size, this beginning the root growth process. Once again, you cannot start growing a pot plant without first germinating the seeds.

How Long Does Germination Take?

Generally speaking, with the right temperatures and the right amount of moisture, a marijuana seed will take between 2 to 5 days to fully germinate. What you need to know here is that you do need to apply a fair amount of water to get this process started.

Moreover, the temperature for weed seed germination needs to remain at a steady 20 to 22 degrees Celsius, or about 68 to 72 degrees Fahrenheit.

The seeds should also be kept in a dark place while this germination process is in the works. If all goes well, it should never take longer than 5 days for this process to occur. What you also need to know is that not all weed seeds will germinate. Some may just be dead ducks in the water. You can usually tell if a seed is healthy by examining in.

Generally speaking, a dark green seed should always germinate, whereas a pale or white seed is a good indication that nothing will happen. When it comes down to it, usually between 60% and 90% of seeds will germinate. If you do this right, you can expect about 4 out of 5 seeds to germinate.

However, there is really no way to tell until you actually do it, because all seeds are different. Sometimes they might all germinate just fine, and sometimes you might get a batch where none germinate.

It does kind of come down to chance, seed health, and the conditions. Trial and error and repeated tries are things you will have to deal with if you are going to attempt marijuana seed germination.

How To Germinate Marijuana Seeds – Common Methods

Now that you know how long it takes for a marijuana seed to germinate, you probably want to know how to germinate them in the first place. Well, there are several common methods used for weed seed germination.

Let’s quickly go over each of them, how well they work, and what you need to do in order to achieve success with each germination method.

1. In Soil

The first and most commonly used marijuana seed germination method is by germinating the seed directly in soil. Germinating marijuana seeds directly in soil works well because it allows for minimal root interference and damage.

In other words, you are germinating the seed in the same medium or place that you will begin the growth process.

This means that you can germinate your seed and start root growth, without having to transfer that fragile seed, with fragile roots, into potting soil. It minimizes the risk of having your weed seed’s root system being damaged.

The Right Kind Of Soil Is Important

First and foremost, when using the soil germination method, you need to ensure that you have the right kind of soil. You can’t just use the dirt from your garden or backyard. It needs to be mildly fertilized, only very mildly as too much fertilizer will cause burns and result in the quick death of your seeds.

The soil should have a pH level of roughly 6.0. Good potting soil can allow your seed to germinate and even provide it with enough nutrients for roughly the first 2 weeks of growth.

Place the potting soil in a small pot and then use your finger to make a little hole, about 1.5 cm or 0.6 inches deep. Take a seed, place it in the hole, and then cover it with soil, but don’t pack it down very hard. It should be somewhat loose.

Do not push the seed down further or mess with it in any way.

Don’t Forget Plant Sprayers

Use a plant sprayer to moisten the soil, ensuring that water gets down to the seed. However, make sure that you don’t apply too much water, as you can easily drown a marijuana seed and kill it.

Some people will begin to provide fluorescent or other types of lighting already at this stage, but technically this is not necessary until you see the plant sprouting from the dirt.

2. In Paper Towel

Another commonly used method for marijuana seed germination is using paper towel or cotton pads. The benefit here is that germination process is very easy to keep an eye on, it tends to be fairly safe, and is very easy to get started. Now, be sure to pick good cotton pads or paper towels, ones that are smooth.

You don’t want to use overly porous materials here because once the roots start to come out of the seed, you run the risk of having them grow into the porous paper towel. The result here will be that the roots are hard to remove from the paper towel, potentially damaging them before you get the chance to transfer them into good potting soil.

All you have to do here is take some of that paper towel, a double layer of it, and fold it in half. Now, take your marijuana seeds and place them in between the paper towels, where you folded it in half.

Once again, use a plant sprayer or just drip some water onto the paper towels to moisten them. Be sure to get them wet enough so that the seeds inside get moisture, but don’t soak it to the point of dripping because you will drown the seeds.

Use A Plastic / Sealable Bag

Here, most people will choose to place the paper towel in a plastic and sealable bag. Don’t worry, there will be enough air in there for a few days. The good part about this is that you can keep an eye on the process. Yes, you can open up the bag, unfold the paper towels, and check to see if the germination process has started.

However, do not do this more than once or twice. For instance, you can check on day 3, and then on day 4 after you have started the process.

Darkness is best for this, so don’t keep them open for long, only long enough to check if the roots have started sprouting.

IMPORTANT: Wait For 4 MM Before Moving To Soil

Once the roots have sprouted, and are about 4 mm long, you then have to place them into soil. Do not place them into soil if they are shorter than 2 mm, and don’t wait until the roots are longer than 5 mm, as the roots will start to grow into the paper towels and cause you trouble.

Just be careful when transferring the germinated seeds to soil, as the root system will be fragile.

3. In Water

The next commonly used method for germinating weed seeds is by placing them directly in water. This method does usually work quite well, but it can also be a hit and miss depending on who you ask.

Most people would say that placing your seeds in water for germination provides them with both too much water and light, thus potentially drowning and killing them. Although, depending on the seeds you have, it can work.

This tends to work best if you leave the seeds in the water for about 1 day. This method is usually pretty quick with germination, and can jump start the process, often only taking a single day for germination.

However, if nothing has happened in the first 3 days, chances are that the method has failed you, and the seeds may have drowned.

Take some normal tap water and fill up a glass, making sure to maintain a steady 18 degrees Celsius, and keep replacing the water every day. The seeds should sprout and the seeds need to be transferred to soil before the roots are longer than 5 mm.

There is the risk here of damaging the roots during transfer, the risk of the seeds getting too much light, and of course, the risk of drowning. Some people do prefer this method, but we find it to be way too risky when compared to the others.

4. In Peat Pellets

Actually one of the easiest ways to germinate marijuana seeds, especially for beginners, is to use peat pellets. Peat pellets are great because they have a high germination rate, usually between 80% and 90%, and they are great for the roots too.

For one, peat pellets already have some nutrients in them, they retain water well, provide a dark place for germination, and you can just take the peat pellets once germination has occurred and plant the whole thing in soil, this protecting the root systems of the seeds.

Simply take the peat pellet, soak it in warm water for a couple of minutes, plant the seed about 1.5 cm deep in it, and then place the peat pellet in a fairly dark area with the proper temperature level.

Once you see the plant beginning to sprout out of the peat, you can then take the entire peat pellet and put it right into your potting soil. It’s a really easy method with a good success rate.


As you can see, if you want to grow your own marijuana plants, the beginning is actually quite easy. Yes, you do absolutely have to germinate your weed seeds, but it is a fairly easy and straightforward process with many available methods. Just choose the one which suits you best, and you are well on your way to having a happy and healthy weed plant.

Germinate marijuana seeds
Put the seeds directly, about 0,5cm deep, into the soil and place a lamp above. If you are using wet cotton wads, place them in the dark, at around 20-22 degrees (soil/water temperature) and make sure to replace the water daily.

How To Germinate Cannabis Seeds

Before we start with the germination there is one crucial thing to keep in mind: cleanliness is a big factor when working with your offspring and it is not limited to the tools and materials you work with, but it includes YOU! For example, if you are a (tobacco) smoker . did you know nicotine is poisonous to cannabis plants just as it is to you? So, work like a surgeon and use antibacterial soap to wash your hands before every operation. Tweezers, scissors, pots, buckets – it ALL must be clean for maximum results at the lowest possible risk of contamination.

For a perfect start for your seeds, you should place them in a moist, cosy environment. Instantly after breaking through the shell, the little root will seek for moisture, so make sure to provide a moist environment for the new life; if you don’t, the seed will die. Keep a high humidity throughout the whole germinating process.

How To Easily Germinate Cannabis Seeds In Soil

While there are a number of cannabis seed germination methods out there, such as the “paper towel method” or germinating seeds in a glass of water, we tend to recommend simply germinating seeds in soil. It is simple, efficient, and how nature intended it to be.

Then you plant your seeds directly in soil, you don’t need to repot or move them, which helps to avoid damage to the seedling. In addition to this, planting seeds directly in soil is very easy. Simply put the seed about 0,5cm deep into the soil and cover the seed lightly. Keep an eye on the environment and keep it warm and humid – 20°C is the ideal temperature. Keep soil moist, but don’t saturate it – waterlogged soil can do more harm than good. You can place a lamp above the seed to provide the adequate temperature for germination. Your precious cannabis seed will happily sprout within a few days!

Molasses is a powerful, yet often overlooked tool when it comes to growing cannabis. Properly used, it can strengthen and boost the very.

Take note that your seeds do not need any nutrients, at least for the first two weeks of growth. New growers often make the mistake thinking they are helping by adding nutrients in this early phase of growth. DON’T! The seed contains everything it needs to grow for a couple of weeks. Add additional feed runs the risk of burning the seedling out before it has had the chance to even begin growing. Feeding your seedling with plain water ensures that it will grow strong roots. If you really want, you can use a root stimulator although it isn’t absolutely required.


The Smart Start seed germinating kit provides the easiest and “smartest” method of cannabis seed germination – with very little risk and with the highest chances for success. This kit contains everything you will need for germination. It comes with 20 small seed pots filled with compost and a packet of Stimulator Mix. The included stimulator activates the essential microbial life in the compost for a fast and healthy growth of your cannabis plants! All you need is some water and of course some seeds, and you’re ready to go!

Whether you are using a warming light, placed over your babies or a heating pad, keep your seeds warm. Basically, there are three components to successful germination: warmth, moisture and darkness. And even after stepping out of the dark period your seedlings will need high humidity. There are various methods to successfully germinating cannabis seeds, but we’ll limit it to three here; the three easiest and almost dummy proof.

Three proven germination methods to kick start your cannabis grow

Let us help you with the first step toward a heavy marijuana harvest. Of course, there’s more than one way to germinate your precious cannabis beans. In fact, we would like to share three of the very best methods and some useful tips to get your marijuana garden off to a flying start.

Cannabis seeds are classified in two distinct categories regular or feminized. Of course, there is a myriad of different strains, hybrids, and even autoflowering varieties. But at the end of the day, they will fall into one camp or the other and hopefully not somewhere in between as is the case with hermaphrodite or intersex plants.

Before you even contemplate germinating your choice of cannabis seeds it’s important to understand what you are dealing with. Regular seeds are cannabis seeds of both gender, meaning the packet is a mixture of male and female cannabis seeds. While feminized seeds will be all females, well 99% of the time they will be.

Occasionally a hermaphrodite will make an unwelcome guest appearance in the grow show. Intersex means a plant which displays both male and female characteristics, usually observed, to the horror of the grower. This rogue pollen has the potential to self-pollinate and/or pollinate the rest of your crop.

If you are growing your own cannabis, you are doing it to produce some prime bud. For this reason, it is extremely important to identify.

Hermies can turn top shelf buds into seeded schwag with just a few pollen granules. Early detection and removal of the culprit is the only course of remedial action. Excessive Stress can induce the condition. If this occurs, the grower is at fault. When cultivating feminized beans ensure you purchase from a reputable breeder and if it goes wrong you have only yourself to blame.

You really do “reap what you sow” when it comes to cannabis cultivation. Getting it right from the very beginning of the grow and following best practice is the most effective way to avoid pitfalls later in the grow.

Before we get into specifics let’s get one thing straight, cannabis should be germinated in darkness, and only a damned fool or a liar would recommend germinating your beans in the light.


Perhaps the simplest no-fuss method of cannabis seed germination is to plant the seed directly into your selected medium. The grower has many choices depending on what type of crop you want to cultivate: soil, Rockwool, coco or hydroponics. Organic purists prefer planting directly into soil or coco, or a blend of the two.

Digging a finger nail depth hole in the medium to place the seed in and cover over before applying a splash of water to moisten the medium is sufficient. Then it’s time to play the waiting game for usually 3-7 days before you see a seedling emerging.

It’s best the medium remain moist, but not waterlogged. Keep a spray bottle of pure water handy to maintain an effective wet-dry cycle from the start. Cannabis roots best in a moist medium with a 20-22C temperature range. Ideally, humidity should be high between 50-70% and maintained in this range throughout vegetative growth right up to the bloom phase.

Our silver bullet solution to cannabis seed germination is the Smart Start kit. It’s a particularly useful starter medium for novice growers and more experienced growers that like to experiment. All you need is a pack of high-quality cannabis seeds and some water to get started.


Our second germination technique is the old “Paper Towel Method”. Simply place your cannabis seeds between two sheets of kitchen roll, grab your spray bottle and moisten but don’t soak the towels and voila!

We recommend placing the moist paper towels in a lunch box with the lid off, then stand the lunch box on its side and allow gravity to also assist the germination process. As with all germination methods, they are most effective in complete darkness at room temperature. The bathroom cabinet is an ideal place to store your lunchbox of magic beans.

Bathrooms are damp and cabinets are dark, so it really does make sense. Give the odd spray of water to keep the paper towels constantly moist and in no time literally 24-48 hours you will be seeing tap roots bursting out.

The only tricky part with this method is that it requires a steady hand to transfer your freshly germed beans into pots or containers without damaging the fragile tap root. Burrow a hole in the medium with a nail or screw 2-3cm deep then insert.

Handle with care and try to pick up the seedling head first and gently transplant easing the roots into your hole in the medium. If you happen to be a total klutz don’t worry simply lay your beans, gently atop of the medium and cover them over carefully with just a pinch of top soil.

PLEASE NOTE: We do not recommend this method because, more often than not, the paper is too wet and the seeds simply suffocate or begin to rot.


To complete our trinity of germination methods we have the Glass of Water Method. Simply drop your beans into a glass of pure water and wait for the emergence of a tiny rootlet. This method is not very scientific nor is it 100% effective, however, it is nonetheless an often used method of germinating seeds quickly.

Sure you may get a few kills but so long as you don’t spill or accidentally drink the water the majority of your beans will be good to go in 2-3 days. We don’t recommend placing the glass next to your night stand, especially if you get thirsty during the night.

The journey to every heavy harvest begins with the germination process. Get it right, and you’ve made the first step toward achieving your objective. Get it wrong and your cannabis grow is done before it’s even begun. So please follow our friendly advice and get it right.

PLEASE NOTE: This is not our preferred method, as seeds placed in a water glass are very likely to suffocate or rot.

The cannabis industry is ready to advance into the rapidly approaching year of 2019. Get ready for some fresh and powerful genetics to hit the scene.

Our advice as a summary: Use Method #1

This first technique is the technique we recommend. We recommend to use the ‘Smart Start’ to germinate seeds. A lot of mistakes are usually made using the first and second germination technique.

Put the seeds directly, about 0,5cm deep, into the soil and place a lamp above. If you are using wet cotton wads, place them in the dark, at around 20-22 degrees (soil/water temperature) and make sure to replace the water daily.
