It’s a stage that begins the life of the plant. Germinating cannabis seeds is a vital step in the 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.
How to germinate marijuana seeds
Seeds. Such a gift to this world. From something so small, may we grow ourselves, our own food, shelter and in our case, medicine! So really, it seems only fitting we give them the best odds at a successful start in life. In this post, our collaborator Light Addict explains how to germinate cannabis seeds in order to be successful.
Having said this, let’s look at how compost inoculant teas can be used to help nullify the risk of unwanted bacteria and pathogens encountered once the cannabis germination/planting process has begun. This is managed through the introduction of beneficial bacteria and mycorrhizal fungi to the process via compost teas used for either pre-soaking your plugs, cubes, potting medium etc. or drenches to the media shortly after germination. These beneficial bacteria and mycorrhizal fungi colonize the rootzone creating a symbiotic relationship with your cannabis plant roots, leading to improved levels of nutrient/water uptake, general plant health and resistance to stresses.
Now a cannabis seed only needs 3 simple requirements to germinate:
So why are there so many different methods bandied about? Simply put, there are lots of different ways to give your cannabis seeds these 3 basic environmental requirements. So, within these simple basic provisions, what are the best ranges to promote a successful germination of your cannabis seeds? With moisture: you’re looking for a medium level of dampness, never soaking, (water method not inclusive). Temperature wise: you’re seeking to provide a range somewhere in the vicinity 23-26C/75-80F. Then lastly, darkness; total light deprivation isn’t truly a requirement. However, as it’s so simple to provide, it’s the option most of us choose. With all 3 of the above requirements, maintaining consistent levels can also aid in success.
Methods to germinate cannabis seeds
One of the oldest, most widely-known methods to germinate cannabis seeds for small-scale growers is the paper towel method. Using some folded up paper towel, we create a bedding layer for the seeds. Place this bedding layer inside an opaque container of suitable size, then dampen it with water via a spray bottle. Place your seeds on top, before covering with more paper and spraying once again with water. Close your container up and then place it somewhere warm to await germination. Once the tap roots have shown, simply plant it in chosen medium.
For simplicity, methods don’t come much easier than this, although again it’s only really suited for the small-scale grower. Drop your seeds into a shot glass, then fill it around 3-quarters with water, before placing your glass in a warm, dark area. You may need to return after a couple of hours, just to tap any remaining seeds that are still floating down to the bottom. Wait once more until the tap root has shown, before planting it to medium. However, please keep this in mind: if germination hasn’t begun within 36 hours, I’d recommend removing the seeds from water and placing them in paper towel to prevent your seeds drowning.
Seed plugs, rockwool cubes and peat pellets
These 3 different starting mediums share the same basic process when it comes to actual seed germination and are all suitable for any size of operation, although some require a little more care and caution when being prepared.
Versatility here is key, as they’re suitable for use with any medium or style of growing utilized further along in the growth process. Root plugs are specifically designed to make the germination process simple and successful, being made of a composition that holds moisture levels within an ideally suited range. Another big plus when it comes to root plugs is that generally they’re made from composted and broken down organic materials. Yet please, check your chosen brand ingredients for yourself. Take your seed and insert into the plug’s hole. Tear a small section of the plug away from a corner or the bottom section and stuff this into the hole to cover the seed. Then place your plugs into your germination space or propagator, using a constant light source and again remembering to keep an eye on moisture levels as you await germination.
CAUTION. Rockwool is a hazardous material. Somewhat like fiberglass, its dust can be breathed in, yet not expelled from the lungs. It also happens to be an irritant. So, both gloves and a face mask should be used when handling it. Rockwool is an inert medium, suitable for all general growing practices. This means, soaking your cubes in pH-adjusted water prior to use is a necessity. Once soaked and let drain, drop your seed into the hole, then tear a corner section off your cube and use it to cover the seed up from the light. Then place your cubes in your propagator under your chosen light source and wait.
Peat pellets are quite similar in appearance and design to the plugs once expanded. One major issue with peat pellets is that peat is not a sustainable source of material, or an eco-friendly one. Peat pellets come dried out, making pre-soaking them necessary. Once ready, they’ll have expanded to over double their original size. Then just make your own little insertion into the top of the pellet, before dropping your seed in and then covering over with another section you’ve torn off your pellet.
Seed, straight to medium
Take your desired pot of media and water an hour beforehand (pH’d, if required, as with soilless). Make a small hole, 0.5-0.75 of an inch is a good depth, then place your seed in and cover over. Finally, place your pot under your light source and wait. As with the other methods, keep an eye on your moisture levels as required. Although we strive to keep moisture levels at a constant, please remember that overwatering the medium can sometimes cause failure of germination. Then take into consideration the feeding requirements for new seedlings: no nutrients are needed in the first week or so of a seedling’s life, even if using an inert medium such as Coco or Rockwool. This is because the seed will be using its own stores of energy up.
5 Ways to Germinate Cannabis Seeds
Have you ever thought of germinating your cannabis seeds? It’s a stage that begins the life of the plant. Germinating cannabis seeds is a vital step in the growing process, and it’s the foundation of all marijuana plants.
There are several ways to germinate these seeds, and we will talk about five of them in this post. But before you proceed, it would help to determine the marijuana cultivation laws of your locality. Whether you use paper towel rolls or plastic containers with holes cut out for drainage, there are ways to do it that work best for your environment. Let’s get right on them.
Germinating Cannabis Seeds in Soil
You can readily try most trusted online retailer to buy DMT Online and germinate your cannabis seeds using soil. It’s the natural place where the plant will grow in the wild to protect the fragile roots. Also, this method has a better growth rate than others.
You can follow these steps to growing cannabis seeds in soil:
- Take a transparent plastic container and fill it with moist soil
- Place it on top, root side down (pointy end facing downwards)
- Keep the soil moist by spraying it with water but not soaking it
- Put the container in a dark warm place (for example, on your refrigerator or near any other appliance that emits heat).
Germinating Cannabis Seeds Using the Paper Towel Method
The paper towel is a simple, easy-to-manage method of germinating cannabis seeds. You will need a non-porous paper towel roll or two, depending on how many germinating cannabis seeds you have, and two clean plates.
The non-porous paper does not allow water or air to pass through, which helps develop seeds without being damaged by air particles. The non-porous towel can help your seed grow without getting stuck on the surface of the towel.
The Paper Towel Seed Germination Process
Here’s a step-by-step process of germinating cannabis seeds using the paper towel germination process:
- Place the non-porous paper towel on a plate.
- Pour water into another plate, and place it below the non-porous paper towel to catch leaks from drainage. It is crucial that you do not pour directly onto germination seeds, as this can cause them to go stale or rot too early in their development. The cannabis seeds must become as moist as possible.
- Place the cannabis seeds on top of the paper towel. Make sure you spread them evenly, as this allows for more exposure to moisture and air throughout their development process.
- Cover your germination dish with another plate. It will help keep moist air around your cannabis seeds during germination periods by blocking off any light.
- Now you’ll have to wait until your seed grows. In most cases, it takes two to four days to grow when put under the right sprouting conditions. If you see a root growing, that means germination has occurred.
- When the roots have emerged from the seed’s shell, it is time to transfer your cannabis seeds into the soil or another container for germinating plants. Please make sure you plant them deep enough not to expose their roots when watered with tap water and plant food mixed in.
Germinating Cannabis Seeds Using Starter Cubes
Starter cubes are small growing mediums consisting of peat and organic materials to germinate cannabis seeds. The cubes come in different sizes, and it would help if you chose one according to your preference. The best ways to grow cannabis seeds using starter cubes include:
- Soaking the peat cube in water before filling it with soil gives your seedling something stable to hold on to while its roots form.
- Sow the seeds into the plug and some water, and the rest of the germination process will take care of itself.
Germinating Cannabis Seeds in Rockwool
Rockwool is an ideal medium for growing cannabis. But before you proceed with this method, it would help to know the dos and don’ts. If you follow it, you’ll discover that it’s one of the best cannabis germination mediums.
It’s made from melted rock and recycled glass, minerals, and other materials. It has a pH of about seven, supports root development, drains well, which suits cannabis well during germination. It also comes in cuboid shapes that make it easy to transplant in soil-based systems or into hydroponics.
All you need to do is soak the cube in water for ten minutes before placing your seed inside it and covering it with more Rockwool cubes or potting soil. Use an anti-algae solution to prevent algae growth and keep the cubes moist but not soggy.
Germinating Cannabis Seeds in Jiffy Pellets
Jiffy Pellets are natural, biodegradable growing mediums conveniently packaged in compact discs. They are effective because they help sprout seeds into seedlings and have an effective survival rate than other methods.
To help seedlings grow, you can formulate the Jiffy Pellet with peat moss, mesh, lime, fertilizer, and ammonium. These pellets are both containers and potting mixes for sprouting seeds.
The mesh securely holds the peat moss in place, and the peat moss is a rich medium of organic materials. Growing marijuana indoors or outdoors with Jiffy peat pellets is an effective method for fostering healthy plants.
The five methods we’ve covered should give you plenty of options for germinating your cannabis seeds. However, if you want to proceed independently, it would be best to follow these important ways.
How to Germinate Weed Seeds – Tips and Methods
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
- 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 open 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. Now you need to move them to the medium in which they will remain for the rest of the growing process. Germinated seeds usually grown in soil, but rockwool for hydroponics is also a good option growing. Or even 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 0.5-0.1 cm 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.
