Germinating cannabis seeds isn’t a complicated process, although it does require a few specific parameters in order to happen successfully. If you’re reading up on how to germinate weed seeds, you’re in the right place; it’s a relatively easy process, you just need to have some patience on hand. The first thing to keep in mind is that your seeds are going to need water, heat and air in order to germinate.
How to Germinate Weed Seeds – Basic Parameters
Moisture is one of the three elements required to successfully germinate cannabis seeds; it essentially helps the seeds to expand and therefore break their shell. Over-watering at this stage can be fatal for your seeds, although harder-shelled and older seeds can take longer to soak through, so some patience is required.
This can be the hardest thing to work with, because temperatures that are either too cold or too hot will mess with your seeds and they won’t germinate. Springtime temperatures are generally what you should be aiming for – seeds can still germinate in colder temperatures, although they can take longer.
How to Germinate Weed Seeds – Germination Methods
There are many different germination methods that growers tend to use, all of which involve water and heat, although they’re not all as effective as others. Some people prefer germinating by planting straight in the ground, using starter cubes or by letting them soak overnight, although our preferred and recommended method is the paper towel method using either plates or an opaque kitchen container. We’re going to give you a brief rundown of the other methods, alongside their pros and cons.
This method is more reliable than others, and they make germinating quite easy. All you have to do is place your seed carefully in your seed plug and follow the instructions when watering; different brands and models have different watering instructions.
Some cubes are made out of peat and soil, and you can move them straight into your flowerpot once they’ve popped. However, hydroponic growers can use rockwool cubes which can hold quite a lot of moisture.
One of the downsides to using starter cubes is that they’re not very handy if you only want to germinate one or two seeds, because they’re usually sold in packs of 50 or more, and once they’ve been opened most cubes tend to dry out within a couple of weeks. Another downside to Rockwool specific cubes is that they’re bad for the environment, can be bad for your health when inhaled, and they’re not the best method for new growers.
Other growers prefer to get rid of the middle man and plant their seed straight into their first flowerpot – it’s essentially how it would be done in nature, so why not follow the natural order? One of the pros when it comes to planting straight in your growing medium is that you don’t have to stress out your little seedling when transplanting, although it can be a bit harder to get the humidity right and you need to bury it just the right amount so that it can sprout.
We highly advise against using this method, as it’s incredibly easy to accidentally drown your seeds. This method involves soaking your seeds in a glass of lukewarm water – it can be any type of cup, although people usually use a normal glass. This method can be effective for much older seeds or for seeds that have abnormally thick shells.
There are a few myths surrounding germinating in water overnight – some people say that if your seeds sink, they won’t germinate, however the truth is that most seeds start off by floating and then as they soak, they sink to the bottom of the glass. This has nothing to do with germination indication.
How to Germinate Weed Seeds – Paper Towel Method
This method is the method we recommend all readers and customers use, as it’s the one that has proven to give us the highest germination rate. We’re going to give an in-depth step by step guide on how to use this method. Keep in mind that you can skip the rooting hormone part if you prefer all natural results, although X-Seed does provide impressive results to start with.
Material Needed to Successfully Germinate seeds
- Kitchen paper
- Opaque plastic Tupperware or two plates
- X-Seed by B.A.C.
- Viable cannabis seeds
We’re going to go through the X-Seed method – if you want to skip this, you can simply skip the steps involving X-Seed and place your seeds straight into your paper towel as stated in step 4. Before you start, make sure you have everything you need at hand, so that you don’t have to waste any time looking for stuff.
Step 1: Soak the seeds
Submerge your seeds in your B.A.C. X-Seed liquid for an hour. Give it a stir every now and then so that the seeds are thoroughly soaked.
Step 2: Germination
While your seeds are soaking, you’ll need to prepare your paper towel and plates (or opaque Tupperware). Make a makeshift “bed” on the bottom plate with damp kitchen paper, but make sure it isn’t soaking. We tend to use 3 layers of kitchen paper; wet the paper and let it dry without wrinkling it, hanging it out kind of like a t-shirt so that all of the excess water can easily drain out. No need to worry about drying it, as you want the kitchen paper to be damp.
Step 3: Separation
After your seeds have been in the B.A.C. X-Seed liquid for an hour, by using a spoon you can carefully extract the seeds from the liquid and spread them evenly across the bottom of your plate or container. An even spread is important, so as the roots of each seed do not get tangled – about an inch apart is good.
Step 4: Cover the seeds
Once you have all of your seeds nicely placed on your plate or in your container, cover the seeds with another layer of damp kitchen paper, similar to the first layer that you put on the bottom. At this point, your seeds should be completely covered.
Step 5: Take care
Once you’ve finished covering your seeds with paper towel, cover them with another plate or put the lid on your container; if doing this in a container, the paper shouldn’t dry out as fast. A mistake made by many growers is that they add too much water to their paper towels if they’ve dried up, but by using a spray bottle you can moisten it some more without overdoing it. If your container is transparent, all you have to do is line the inside so that absolutely no light can get in.
Step 6: Temperature adjustments
Once you’ve isolated your seeds from light, you should leave it somewhere with a nice, neutral temperature. During winter it’s often harder to find a good spot, so you should try and find a heat source that isn’t excessive. You can use a computer modem, or even a softly powered electric blanket. Items like play-stations can get too hot and could end up cooking your seeds, so take care where you put them.
Step 7: After care
Once your seeds have opened up they’ll shoot out a small, white root. This means you need to be extremely careful when handling them. Don’t leave them for long because once they’re open they should be moved to soil.
Step 8: Moving to soil
Now that your seeds have officially germinated, you need to move them to the medium in which they will remain for the rest of the growing process. Germinated seeds are generally moved to soil, but they can also be planted in rockwool for hydro growing, or in a coco jiffy if you want to cultivate in coco coir. In this article we’ll be dealing with the most common method: planting seeds in soil.
How to Germinate Weed Seeds
Start by filling a small pot with soil, no more than half a liter. Water it before even thinking about planting your seed. Once the soil is damp enough to weigh down the plant pot, use the tip of your finger to create a small 0.5-0.1cm hole in the middle of the soil, and deposit the seed in the hole with the root facing downwards. Then, cover the seed with a little soil so that it’s just under the surface. The last step in this process is to put your plant pot in the sun or under your lamps (wherever you’re planning on growing it). Within a couple of days you should see that first sprout, that will keep on growing right until the end. In some cases, it may even take a matter of hours.

Figuring out how to germinate weed seeds isn't that hard, but choosing the right method can determine exactly how high your success rate is.
You bought beautiful Premium Pro Seeds from Suzy Seeds and of course, you want to get started. First, you have to germinate the seeds. Below, I will discuss my favorite way extensively, but also suggest other good methods. Suzy Seeds exclusively sells feminized cannabis seeds, so you don’t need to remove male plants, which applies also to autoflower cannabis seeds. It’s good to know that a cannabis seed does not need light to germinate. What is important, though, is a humid environment and an ambient temperature of around 20 °C. In general, there are three ways to germinate cannabis seeds: – In a cup of water – On a damp surface – In soil. My favorite way to germinate the seeds is to put them in a cup of water and then between a damp paper towel. This goes well in 99% of the cases. How long does it take cannabis seeds to germinate in general? Or how do we germinate autoflowering seeds? The time depends on the strain or type of seed, but autoflowering seeds germinate in the same way and time as feminized or regular cannabis seeds. That is why I will more extensively describe this first way.
We recommend not to touch the seeds or the seedlings with your hands. If you do anyways, make sure your hands are clean and if possible use plastic gloves.
Suzy’s favourite germinating procedure
Maintain an ambient temperature between 20 and 25 °C, otherwise, the seeds will not or at least not optimally germinate. Fill a cup with water and put the cannabis seeds in it. Get the seeds out of the water after 12 to 24 hours and spread them on a plate between two layers of damp paper towel. Put the plate in a dark and enclosed place. It’s important to make sure that the paper towel remains damp. I moisten the paper towel every 6 to 12 hours. Do not use too much water. The seeds only need to be damp. Within 48 to 72 hours, the seeds should pop open. But be patient, because it can take longer (6 days at the most). When the root becomes visible (the white sprouts as you can see on the picture above), you need to plant the germinated seeds. If you do not plant them in due time, the root can be damaged.
Suzy’s Tip: Try your germintion method on a couple of seeds (maximum 3). This way, you can test if your method works well. Often a wrong germinating method is used and the seeds don’t germinate. Do you want to germinate your seeds in a different way? Continue reading.
Germinating cannabis seeds in a cup of water
Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Fill a cup with water and put the cannabis seeds in it. After 3 to 5 days, the seeds should pop open and a tiny root should come out. As soon as the sprout is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Planting the germinated seed has to be done with lots of care and attention. Put them 0.5 to 1 cm in the soil with the root down. This way, the root (the white sprout) will more easily grow downwards.
Germinating cannabis seeds on a damp surface
Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Put the cannabis seeds on a surface that holds moisture, like wadding, paper towel or tissues on a saucer. Moisten the surface well, but avoid making it too wet. The moisture evaporates quickly at room temperature, so check during the period that the seeds will germinate if the surface is still damp enough. You can also cover the seeds with damp wadding or tissues and another saucer on top. Because of the moisture that gets into the seeds, they are activated and start to germinate. As soon as the germ is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Put them 0.5 to 1 cm in the soil with the root down. This way, the root will more easily grow downwards.
Germinating cannabis seeds in soil/compost
Direct germination of cannabis seeds in the soil is a commonly used method. You don’t have to handle the fragile plant, so it is not disturbed in its growth process. However, the chances that the seeds will germinate are lower than when applying the other methods. When using this method, it is important to use good soil. You can inform yourself about the different types of soil at your local grow shop. Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or not optimally germinate. Put the cannabis seed about 1 cm deep in the soil. Cover the hole with some soil and gently press. The soil needs to be light so that the plant can easily grow to the surface. Solid soil is hard to penetrate for the roots and will cause a delay. The seeds will germinate under the ground and will come to the surface after 4 to 10 days.
- – Be patient, the time it takes to germinate may differ according to the strain.
- – Germination of cannabis seeds in soil can differ between 2 days and up to 4 or 5 days in some cases.
- – Make sure that your hands are clean when you touch the seeds.
- – If you spread the seeds on wadding or tissues, moisten the surface well and keep it moist until the seeds start germinating.
Best way to germinate the cannabis seeds is to put them in a cup of water and then between damp paper towel. Direct germination of cannabis seeds in the soil is a commonly used method. To germinate autoflower seeds we apply the same methods.
