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:

  1. Glass of water
  2. Wet towel
  3. Directly in soil
  4. Stone wool blocks
  5. 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.

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.

Ed Rosenthal, Author, Educator, Social Activist, And Legalization Pioneer

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.

Ed Rosenthal, The Guru of Ganja

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.

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.

  1. Climate conditions needed for germinating marijuana seeds.
  2. 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 germination

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.

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.

How To Germinate Old Cannabis Seeds

We can only expect to use the old seeds with the cost of seeds floating above potheads’ reach. However, improper or long-term storage of seeds can cause infertility – and they cannot germinate. However, how do we let those old cannabis seeds come to life again? This guide will help us convert the relics into a sea of green sections of robust cannabis fields!

Sorting Old Cannabis Seeds

The first step in any farming process is to make sure we have the right seeds, and the same goes for weeds. When harvesting autoflowering marijuana seeds, everything is preserved, and nothing is lost. This means that all types of seeds are ripe and immature. How do we distinguish good seeds from bad ones? You are considering the following.

Sorting Seeds By Color And Shape

Whether we obtained the seeds from a seed bank, a store, or a retailer, different cannabis seed strains have different colors. Mature cannabis seeds acquire a dark coat, while immature ones are brighter and usually white. The most visible colors are brown, tan, and sometimes black. In contrast, bright yellows and whites quickly identify immature seeds.

Cannabis seeds are known for their aesthetic properties and shape. Round and symmetrical seeds are best. Larger seeds have a reasonable rate of germination compared to small seeds, which tend to be immature.

Classification Of Seeds By Hardness

Although the seeds have taken some time inside storage containers, ripe weeds seeds’ hardness is not compromised. Hard and tough seeds with a smooth shell guarantee a reasonable degree of germination. Also, pay attention to wavy and cracked seeds. They will lose time and energy and will not germinate after planting.

Ways to Germinate Old Cannabis Seeds

Below we will go through 3 popular methods used to germinate old weeds seeds. Remember that we have to do the part by trying to keep the temperature between 26 ° C – 28 ° because that is where the clones seem to season-best. You must also ensure that the seed is kept in a dark area, as light can slow down the germination process.

Method 1 – Scarification

The first method is scarification. This includes causing injury to the seeds’ outer shell to allow water and air to enter, which is essential for germination. For manual scarification, we will need a container or box lined with sandpaper or any coarse material to scar the seeds’ outer surface. Put the seeds in a container or box and shake. After a while, we will find that the roots become dull, and we can see parts of the sources inside the container. Once we scare the outer shell of the cannabis seeds, we can germinate them as usual.

Method 2 – Carbonated water

The second method involves the use of carbonated water with a pH below 7. This slightly acidic solution absorbs the outer layer of the seeds. Put the seeds in a container full of carbonated water and wait for about two hours. The solution loosens the seed coat and allows it to absorb water, which helps germinate.

Method 3 – Mixture of hydrogen peroxide

Method 3 requires that we use a mixture of hydrogen peroxide to soften the seed’s outer skin. It would be best if we were careful when mixing the peroxide solution, as we can burn the seed, and it will never germinate.

To use a mixture of hydrogen peroxide for the germination process, use 1 to 2 drops of 99% hydrogen peroxide in a glass of water. After soaking for 24 hours, the outer shell is softened enough to germinate the seeds.

In addition to chemical and mechanical scarification, we can use other DIY methods to loosen seeds. For example, we can use a small knife to scratch or open the seed coat. We can explore different approaches as long as we do not damage the seed embryo.

  • One part 3% hydrogen peroxide with six parts water.
  • One part 4.5% hydrogen peroxide with nine parts water.
  • One part 6% hydrogen peroxide with 12 parts water.
  • One part 30% hydrogen peroxide with 60 parts water.

Always Use Clean, Fresh Water

Clean and clean water contains oxygen and hydrogen molecules. These are two life-supporting elements necessary for germination. Soaking the seeds for at least 12 hours allows water to enter living cells, a process known as osmosis. Now that the internal conditions promote germination, the semen embryo expands and breaks out of the protective sheath.

Conclusion

Old cannabis seeds sometimes pose a challenge for germination. You can sort ripe seeds, release the hard protective layer by various methods, try new chemical germination enhancers, or use biocatalysts. Similarly, soaking the clean, soft seeds in clean water will push the embryo out of its protective blanket. After trying some of the above processes to germinate the old cannabis seeds, we can be sure to grow healthy and living plants and expect good yields.
