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:
“Different Modes of Hydrogen Peroxide Action During Seed Germination”
How to germinate cannabis seeds?
Germinating marijuana seeds can be done in different ways. Each experienced grower has his own prefereces. Before we dive into the diverse methods it’s a good idea to contemplate a little on how nature deals with this.
After the female cannabis plant has been pollinated by the male cannabis plant pollen, the female weed plant starts to produce seeds. This takes 9 weeks on average. When the seeds have matured the weed plant starts to rot causing the seeds to fall to the ground, winter begins.

It starts to freeze, then thaw setts on and the weed seeds start to germinate. This proces teaches us multiple things.
- Climate conditions needed for germinating marijuana seeds.
- How does nature store it’s marijuana seeds?
Cannabis seeds germinate in nature after the freezing stops. A moist cold period, especially low above ground where the seeds reside.
The cannabis seeds are stored during winter. This teaches you to store your cannabis seeds in a cold environment for them not to lose their ability to germinate.

Cannabis seeds germinate in a glass of water.
Throw the marijuana seeds in a glass filled with slightly lukewarm water and wait. Is it really that easy? Yes! The glass filled with the water can be kept at room (ambient) temperature. The water will quickly become dirty. Therefore it is neccessary to refresh the water in time in order to prevent the seeds from rotting
Because the seeds are in the water for quite some time, the germs are very fragile. Keep this in mind when repotting. With multiple species, it is important during germination to label the glasses so you don’t forget which species of cannabis resides in which glass.

Since the water needs to be replenished, this is the most labor intensive germination method
Germinating cannabis seeds on a moist surface
A heavily used weed seed germination method is using a moist surface. This surface can consist of moist absorbing materials like kitchen roll paper and cotton. This is often done at living room temperatures which makes the moisture vaporize quickly. A commenly made mistake is underestimating the speed at which the moisture vaporizes. When the seeds lay dry, nothing will happen (they will not germinate).
To prevent dehidration the moist surface can be placed within a closed wrapping, for instance in between two dinner plates creating condensation. Also, it is possible to spray the surface with fresh water on a daily basis in order to prevent dehidration.

A recently discoverd video shows a do-it-yourself method that doesn’t need any maintenance. Set it and forget it.
Germinating cannabis seeds in soil.
Germination marijuana seeds in soil is the easiest approach in our view. What is important? Right, MOISTURE! Don’t let the soil get dehidrated but also do not make it ludacrisly wet. Put the seed about 5 milimeter deep and moisturise the soil. Keep at room tempurature. Check the soil daily for dehidration. The perfect soil is special sawing soil but regular potting soil or even garden soil are also fine. As long as the seeds are not put to deep into the ground and do not get dehidrated things will work out fine.
Why using this method? Repotting is not neccessary as the seed is allready in soil and so no chance of damages during repotting occurs. Just occasionally check soil humidity, that’s all.
Germinating old, hard to germinate seeds
- Do you keep old seeds from the 80’s or maybe earlier in your fridge?
- Do you keep seeds in your desk that have been stored incorrectly?
These are two examples of seeds that are hard to germinate.
Research shows hydrogen peroxide stimulates germination of seeds. Healthy seeds will germinate in a hydrogen peroxide bath within 24 hours. Hydrogen peroxide is for sale at your local pharmacy for just a couple of euro/pount/dollar etc. Hydrogen peroxide is normally used for: rinsing when have olcers, oxidising, bleatching (hair), disinfection (in dencer concentration) even of drinking water.
Mix the hydrogen peroxide with regular tap water and put your seeds in it. Proportions: 1 part of hydrogen peroxide (3%) compares to 5 parts of water = 0.5%. Learn more about it at this post at the weed forum
General information on cannabis seeds germination
In the above explanation germination seeds at room tempuratures is regularly discussed. Research shows seeds like warmth and moisture that makes for the perfect germination conditions. When we look at nature, this is not a neccessity. Outdoor growers are advised to saw directly on full open soil so the roots will not be hindered while developing.
Be aware of the fact that the hatchlings need protection from snails, birds, rabbits and other leaf eaters when germination from open outdoor soil. Germs can quickly turn into a nice snack for these anymals. Therefore you need to saw extra seeds, and put a transparrent cup over the germs. Use a copper ring to protect the germs from snails
Snails hate copper.
- Is to much moisture possible? YES! To much moisture can make your seeds or germs rot so keep this in mind.
- Don’t forget to lable.
- Cannabis seeds like dark conditions.
- Germation periods vary among species and conditions, up to a two week diffence.

Study on Best Way Germinating Marijuana Seeds
Here at Marijuana Seed Breeders, we get many questions. From Beginner to Expert.
We love helping growers.
In fact, we try to address frequently asked questions into articles so that everyone, even non-MSB Growers can benefit.
One of these questions is about germination: what is the best way for germinating marijuana seeds?
Interesting one, because perhaps is our best way, not your best way. Therefore we created the article How to germinate weed seeds.
In the article we give steps for 5 frequently used cannabis germination methods:
- Glass of water
- Wet towel
- Directly in soil
- Stone wool blocks
- Using a starter kit
We also give pros and cons to every method. So this should give you enough information to determine what is the best fit for your next growth.
Which Germination Method is the most used?
Every spouted seed counts. To more plants the better, right?
That’s why we are interested to understand how marijuana growers around the world germinate their cannabis seeds.
When we ask people this question we get a lot of different answers. Which germination method is the most used one?
We had an idea, but we didn’t know for sure.
It was time for a survey amongst our beloved MSB Community. We also reached out to experts in the field to learn more about their preferred method.
We were blown away by the number of enthusiastic replies! Both from our MSB community as well as the experts.
Yes, sure we received replies, just confirming one of the 5 methods.
But the larger group of people actually took the time to reveal their ‘secret’ to cannabis seed germination!
But first: let look at the statistics from our own research.

Dr. Dina, The Queen of Cannabis, Co-Owner of AHHS WeHo
When someone gets a nickname from Snoop Dogg, and when that person is referred to as The Queen of Cannabis, the Mona Lisa of Mary Jane as well as The Queen of Weed AND the main character of the 8 season series Weeds is based on their person, then you know that you are dealing with a true expert.
I prefer to germinate My seeds in root gel (clonex) and stick them in cubes. Paper towels work well too, but I think the root gel gives the seeds the extra push to become a strong plant.

I use starter trays and plugs from iHort – EXcel T-50 and 32 Star Excel trays to start seeds. They come pre-moistened, with a little hole to drop a seed.
I use the 50 per tray when I will be transplanting within two weeks and the 32 per tray for growing up to 3 weeks.
When I’m using fresh seed, I just drop them into the hole in the cube.
With stale seeds, first I soak them in a 0.5% hydrogen peroxide (H2O2) solution for 3-4 hours. The recipe is 1 part drugstore 3% H2O2 to 5 parts water. This sterilizes their surfaces. Then they soak in mycos and liquid kelp solution for about 6 hours. Then they are placed in the cubes.
Upon first signs of germination, I water them with mycos and kelp to promote root growth. The next day they are watered with a weak combo of veg and flowering formula about 400 PPM.

James Loud, Founder of Loud Genetics
Well it’s a loaded question because it depends on scale.
I sterilize in an h2o2 Soak then germinate in a jiffy #7 typically. However, large scale I prefer a needle/vacuum seeder to place the seeds evenly in the substrate.
Well and with autoflower I believe direct sow in optimal conditions can yield better results.

I use coco plugs. I gave up the wet paper towel method years ago because managing the moisture was too cumbersome.
I buy coco plugs that come in the 50-cell sheet, make a light nutrient mix, put all of the plugs in a pitcher of the nutrient mix, squeeze them to fully saturate them with the mix, put them back in the cell sheet, push a seed into each hole, and put a dome on the tray under the light.
Then I just keep the plugs moist. The seeds start to pop in about 3 days. Some take up to a week. I leave them in there until they overgrow the tray, then transplant into 3″ pots.
Jesce Horton, Founder and CEO, LOWD
I’m a water glass guy. I like to know before planting which seeds are more vigorous and then assess based on that benchmark throughout the growth process.
I carefully pull the seeds with a spoon and drop them into a coco mixture a day or two after they pop.
