HOW TO GERMINATE MEDICAL CANNABIS SEEDS Before starting to grow your own medical cannabis, you should read some important information about the process of germination. Basically, the process The most known methods to sprout your seeds and get your grow cycle going in no time. 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 MEDICAL CANNABIS SEEDS
Before starting to grow your own medical cannabis, you should read some important information about the process of germination. Basically, the process involves soaking the seeds in distilled water or stone wool blocks. You can also try jiffy pellets. However, be sure to avoid exposing the seeds to direct sunlight. The right moisture balance is the key to germinating medical cannabis seeds successfully.
Soak Medical cannabis seeds in distilled water
The first step in germinating your medical cannabis seeds is to soak them. The same process is followed as with any soil-based growing medium. The benefits of soaking cannabis seeds in stone wool blocks are that they retain moisture and do not need to be watered at all, especially during the early stages of germination. Once the stones have been soaked and dried, place them in a plastic tray or tub with a lid. Large cake tubs work well for this task.
Soaking cannabis seeds in distilled water is a simple and effective way to get ready to plant your flowering kush. Make sure you soak them overnight. To do this, fill a glass cup with about three-quarters of water. It should be pH neutral and lukewarm. Also, you should soak them for several days if you intend to grow a large plant.
Soak Medical Cannabis Seeds In Jiffy Pellets
Once you have soaked your marijuana seeds, you can transplant them into a pot or direct-seed your plants in the soil. Seedlings will develop a root zone and spread through the jiffy pellet. They will begin to develop “true leaves” – these are larger than suckers and look more like typical cannabis leaves. This is a sign of future growth and establishment.
Avoid putting cannabis seeds in direct sunlight
Some horticulturists recommend sterilizing the soil before planting cannabis seeds into it to germinate. Sterilizing the soil can be achieved by placing it in a convection oven at 200F for 30 minutes or by using a microwave on high for two minutes. You can also do this step outside in the sun for ten days. Water the soil, then make a small hole with a pencil eraser and plant the seed. After about a week, it should sprout its first tail.
Orient medical cannabis seeds
Orient cannabis seeds are similar to most marijuana seeds in that they are slightly oval in shape. At one end, they have a point, and at the other, they form a crater. These two ends are called the crown, and the crown should be facing upwards when you plant them. Imbibing water is the most important thing to remember when you germinate cannabis seeds. If you do not, the plant will grow runty and will never reach the light.
Check pH of water
Before germinating your cannabis seeds, you should check the pH of the water. Cannabis prefers a pH range of 5.8 to 6.2, but higher values may result in Fe deficiency and interveinal chlorosis in the upper leaves. Attempting to lower the pH of your substrate can be challenging and may not result in the desired outcome. However, using an acidic-based fertilizer will moderate the pH of your water over time.
In preparation for the seedlings, you need to test the soil for its specific characteristics. For example, the soil should be between six and seven pH, have the right amount of water retention, and allow air to pass through. Some soils are so compacted that they are not conducive to growing cannabis. The best location for the cultivation of cannabis seeds is a sunny, flat area, with lots of privacy.
Transplant cannabis seeds
Transplanting cannabis seeds is easy, but there are some tips you should remember. First of all, make sure that you don’t transplant too soon – this will seriously damage your plant’s rootstock. Second, always prepare your new growing medium properly to avoid soil nutrient imbalances and pests. Lastly, make sure to recycle your old earth to maintain pH levels. It also helps to loosen the soil and increase oxygen levels.
Germination Guide for Autoflowering Seeds
Seed germination is the first part of a successful grow cycle, to help you start your cannabis plants with the right foot, here’s an autoflower germination guide that can be used not only for cannabis but for tomatoes, mangos, strawberries. you name it!
Sebastian Good is talking about the best way to start your autoflower seed and germinates Strawberry Pie Auto.
So here’s how to germinate cannabis seeds with the best-known methods and a couple of tips that will get you harvesting in no time.
1. First Things First: Know the anatomy of your cannabis seed
The process of autoflower germination can take up to 10 days, in order to do everything correctly and know if everything’s going well, we need to know a little bit more about the seed. First of all, we need to understand the anatomy of a cannabis seed. The cannabis seed has a dark brown, hard, and often striped, shell, this shell is what protects the insides which are extremely fragile.
When germinating, we need to hydrate the seed, this will soften the seed’s shell and allow water to reach the embryo, when the water reaches it, the embryo will “activate” and start developing.
Have in mind that it’s possible to drown the seed, so we need to keep an eye on moisture levels, also making sure it doesn’t dry out. With a softened shell, it will be easier for the radicle to come out and this is when you’ll see the white taproot slowly appearing, and once it reaches 2-3cm, it’s time to plant it.
As soon as the seedling comes out of the medium, you’ll often see the shell stuck on top of the cotyledons, which are the tiny round leaves that you’re able to see once the shell has detached from the seedling. Those leaves are responsible for feeding the plant until the first set of true leaves appear. Also, there isn’t the best way to germinate marijuana seeds, you can do it any way you want, as long as you keep proper conditions, your seeds will germinate. So, if you’re wondering how do you germinate autoflowering seeds? Read along for the best methods.
2. The Best Conditions For Germinating Seeds
As you may know, cannabis plants need certain conditions depending on the stage they’re in, maintaining these conditions are the best way to ensure your plants will thrive, and when talking about seeds and germination, it’s no different.
Obviously, you can grow cannabis plants in less-than-ideal conditions and they will still grow but it may end up affecting the yields or quality of your harvest.
When talking about germinating auto seeds, germinating in less-than-ideal conditions will decrease the chances of sprouting, so unlike growing cannabis in bad conditions, which will still grow but can affect the harvest, germinating in bad conditions can end up killing your seeds. So when germinating autoflowers you should keep the temperature between 21-26°C and the humidity as close as 90% as you can.
3. Top Tricks For Germinating Old Seeds
As said above, germinating in the ideal conditions will guarantee successful germination but sometimes seeds may be old or have been kept in bad conditions and can be hard to germinate. So, to help you germinate old seeds, here are a couple of tricks that will increase the chances of germination. But first of all, you need to know the best conditions to avoid these problems.
How To Properly Store Seeds
If you are storing seeds for your next grow cycle, you need to keep them in ideal conditions. If you’re going to germinate them during the next couple of days there’s no need to do anything extra, other than keeping them in a cool place and in complete darkness but if you’re planning to store them for months or even years, you should keep them in the fridge.
You should keep your seeds in an airtight container in a fridge set at 6-8°C with a relative humidity of between 20-30%, if you can’t set your fridge to the temperatures mentioned, just keeping them in the fridge will increase the chances of germination. Just have in mind that the better the conditions, the longer your seeds with last.
Soak in supplemented water
As cannabis seeds get old, the shell hardens and can make it hard for the water to reach the embryo, and if the water doesn’t reach the embryo, your seeds won’t sprout so if you’re dealing with old seeds, you can soak them in supplemented water.
To do this, you can fill a glass cup with water and add around 30ml of hydrogen peroxide and leave your seeds soaking for 12hs, this should do the trick. You can also use germination boosters that you find in grow shops but usually, hydrogen peroxide works, also, make sure the water is around 22°C and it’s not getting direct sunlight.
Scarification is a method used to make ridges on the seed to help water pass through, to do this properly, you will need a piece of sandpaper but you can improvise and do it with a matchbox. The goal is to thin out the shell so that the water can reach the embryo easily, just make sure you don’t overdo it and end up harming the embryo inside.
Slightly Open The Seed
As you may have seen, the seed is made out of two halves and has a ridge around it, if your seeds are old, that ridge may end up hardening too much and the seed won’t sprout. So to help your weed seed germinate, you can use a knife or any other tool with a thin point to gently insert it in between the ridges and slightly separate it, after this process, you can soak your water and germinate it like you normally would.
4. Paper Towel Germination Method
The paper towel method is the easiest of all methods. You’ll need :
- 2 paper towels
- a plastic container or plates
Moisten the paper towels and wring them out so they’re damp but not completely wet.
Place the seeds on the paper towel, fold it over the seeds and place it in a plastic container, cover it with the lid to keep moisture in (can also use two plates instead of the plastic container, place the paper towel on a plate and use the other one to cover).
Place the container in a slightly warm and dark place. Remember to check on it daily, we must ensure the paper towels never dry out, the seeds need to keep absorbing moisture, it’s likely that the seeds will never germinate if they don’t. Sprinkle a little bit of water if needed, you’ll know they’re ready to be transplanted when the radicle is around 1-3cm long.
If the paper towel starts having a bad smell, it’s a sign of too much water, let it dry for a couple of days, and if the papers continue smelling bad, change the paper towels.
5. Soaking Overnight In A Glass Of Water
After many years of experimenting and looking for the best way to germinate our Fast Buds seeds, we must say that this is definitely one of the most effective ways.
This method is especially effective for seeds with a harder shell or older seeds. You’ll need:
As the title says, grab a glass cup and fill it half with water.
Place the seeds in the glass and leave it in a dark place, let the seeds soak for up to 32 hours.
Most viable seeds will sink after a couple of hours and you should see the radicle after a couple of days. Remember that some seeds may need longer until you see the radicle coming out. If they haven’t sprouted after 72 hours, add a few drops of hydrogen peroxide to kill accumulated bacteria in the water and return to the darkness for 2 more days.
6. Using A Germination Chamber
When you get a bit more experienced, you’ll wanna look for more professional tools and the germination chamber is one of them. It consists of a plastic base with small square cells (can come with up to 256 cells, each cell supports 1 seed), on top of a heat mat, also comes with a humidity dome, basically looks like a small greenhouse. They’re very cheap and you can make one at home.
The chamber can be used with any type of medium, Rockwool cubes, peat pellets, coco fiber, perlite, or even soil and they keep the best environment for sprouting seeds and the first days of the seedling.So how to germinate a marijuana seed in a germination chamber? To start germinating, make a small hole (1-2 cm) in moisten medium, cover without applying pressure, turn on the heat mat and spray the humidity dome, it should take a couple of days to see the seedling coming out.
7. Rockwool Cubes And Peat Pellets
Rockwool cubes are small cubes made of rock and sand fibers, with the consistency of cotton candy almost, they absorb a lot of water and usually are used for germinating seeds and clones. Using them along with the germinating chamber has an advantage, being easy to transplant to the next medium or container.
Rockwool and peat pellets are an easy way to germinate seeds but can be easier to overwater your seeds.
They also can be used along with clay pellets in hydroponics. One of the bad aspects of Rockwool cubes is you can easily overwater and get root rot. Peat pellets are similar to the Rockwool cubes but are made of compressed peat moss and come in a small disc shape. To germinate in either one of them, we will use the same technique explained before, moisten the Rockwool or peat pellet, make a little hole (1-2cm) and place the seed inside, cover it gently without applying pressure and you’re all done. You can place the pellet or cube directly in any type of medium or hydroponics chamber, after sprouting, the roots will continue to grow down, even if they reach the end of the Rockwool or peat pellet.
8. Planting Directly In Medium
Sometimes the simplest way is the better way. As it happens in nature, we can also sprout our seeds in our medium of your preference (coco, soil, perlite, etc..) Just grab a pencil, or even with your fingers, make a little hole (1-2cm deep), and place the seed in it, the medium must be moist but not soaking, then cover with soil without applying pressure.
Every time you transplant a seedling, it needs some time to readjust and can cause stress, thus one of the biggest benefits of this method is you don’t have to worry about damaging your seedling when transplanting or shocking it because it already is in its final place.
9. Top Tips to Improve Seed Germination
Planting the Seeds Correctly
Cannabis seeds have an oval shape with one of the ends being sharper while the other has an indent known as the crown. When germinating cannabis seeds, it’s recommended to plant the seed with the crown pointing upwards as this is the end where the cotyledons usually come out from.
Don’t Let the Substrate Dry Out
The germination process relies on moisture to activate the biological processes that provide the energy the seedling needs to break through the seed shell and start growing. This means that the more moisture absorbed, the better. Note that the keyword here is moisture, you definitely don’t want to drown your seeds. Anyway, once the seed is in the paper towels and the germination process has begun, make sure to check regularly to ensure it’s still moist, and to help with this, it’s recommended you keep it in a warm damp place.
For better germination rates, you can opt for a heating mat and/or germination chambers, but it really doesn’t matter if you’re germination your seeds in the soil, jiffy’s, Rockwool cubes, paper towels, etc… Make sure to keep the substrate moist and you will have great results.
Planting the Seed at the Right Depth
One of the bigger issues among beginner growers is planting the seed at the right depth. These problems can get worse if you are watering the substrate after the seeds are planted. Remember, burying the seed too deep can cause it to not develop while not burying deep enough can cause the taproot to over-bend and develop a weak stem, and sometimes stunt growth.
This is why we recommend burying the seed at around 2 cm deep. You can do this by using a ruler, marking the 2 cm mark on a straw, or any other utensil that allows you to do this. Then plant your seed and cover it with the substrate without pressing too hard.
Avoid Planting several Seeds in the Same Pot
Sometimes you may not have enough substrate or pots, typically, this is when you would plant multiple seeds in the same container but they usually do not develop correctly due to several reasons. Now yes, you’re saving space and substrate but you’re definitely not helping your plants thrive as first of all, the roots need enough space to grow, and germinating in the same pot can cause the roots to fight for space.
Apart from fighting for space, if all the seedlings make it to the vegetative stage, they will continue competing for light and by doing this, you will not get the most out of each plant. Lack of light can also cause the stem and branches to grow weak which can cause problems during flower so make sure to plant one seed per pot unless you’re growing in 100-200L or bigger raised beds.
10. In Conclusion
There’s no such thing as the best way to germinate marijuana seeds, a successful germination is considered when you see the first leaves, known as Cotyledons, cannabis seeds germinate correctly with relatively high temperatures and humidity. To successfully reach the flowering stage you’ll have to use different techniques, not only for sprouting but to keep the plant happy and healthy until harvest.
Whether deciding which germination method to choose or getting ready for your first successful grow setup, our advice for beginner growers will be to start with autoflowering strains. If you look for something easy, quick, and easy to maintain, like Zkittlez Auto and Gorilla Glue Auto, there’s nothing better than choosing to grow autoflowers.

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. Find the best strains at our Cannabis seeds – Buy Marijuana Seeds section.
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.
