The Most Common Ways To Germinate Cannabis Seeds
News Americas, NEW YORK, NY, Weds. May 31, 2022: Marijuana seed germination is a simple process, but it is critical for starting the crop in the best possible way.
There are several methods for germinating cannabis seeds. You can try to germinate weed seeds in a glass of water or use any other method shared below. All of them are correct, but some are preferable to others.
We must always germinate the seeds before growing them indoors, outdoors, in hydroponic or organic crops. To accomplish this, you must follow a series of simple steps ideal for effective and rapid germination.
This post will discuss the various methods for germinating marijuana seeds. We will also provide you with a summary of the benefits and drawbacks of each technique. Let’s get started!
How to germinate cannabis seeds
The first step is to summarize the conditions that must be met for adequate germination. The first thing we must control is humidity or water.
We can use tap water without issue unless it has a very high EC (from 1).
In the meantime, a small amount of distilled or reverse osmosis water will suffice.
Many growers typically add a few drops of hydrogen peroxide (hydrogen peroxide) to the water. As a result, the water contains more oxygen. In addition, hydrogen peroxide’s antifungal properties are used. This reduces the likelihood of fungi appearing.
The pH level of the water must be close to 6. The temperature should be around 22oC, and complexes or root stimulators can be added if desired.
Best seed germination substrates
- On the one hand, there’s Jiffy (pressed peat or coconut tablets)
- Rock wool cubes
- Paper napkins.
- Tacos with Root Riot Spread
Once we have the water and the medium for germinating, we must determine the best conditions for growing.
It is recommended that they be kept in a dark and humid environment, but they must be well ventilated. It would help if you also held it at 25 degrees Celsius.
There are some small greenhouses on the market that simulate ideal seed-germination conditions.
Suppose we use kitchen paper as a germination medium. We must maintain these conditions until the seeds germinate, that is, until the radicle appears, which will later become the plant’s main root.
The seeds are planted when this article is about 1 cm long, and after a few days, a tiny seedling can be seen growing.
Next, we’ll go over the various methods for germinating seeds:
Substrates and media for cannabis seed germination
Now we’ll go over the most common methods for germinating seeds. Keep in mind that the media must be wet with the previously mentioned water.
1. Peat jiffy
Jiffy is pressed, and dry peat plugs. It would help if you soaked them for some time before transforming them into a cloth bag of the substrate.
Usually, seeds are sown directly in the jiffy without first germinating. In other words, the seedlings germinate now in the jiffies where they will grow. The plant is then transplanted into a pot to begin the growth phase.
Jiffy comes in various sizes and materials, such as peat or coconut fiber. Because this substrate retains a good amount of water, they do not need to be hydrated during the germination stage.
2. Rock wool
Another germination method is Rockwool cubes or plugs, which are widely used, especially when using hydroponic or aeroponic methods. This method cannot contaminate the system with peat or coco residues, as occurs when cultivating with a jiffy.
The seeds germinate quickly in this substrate, but You must control the humidity level of the rock wool because it dehydrates, unlike jiffy, which retains moisture. As a result, a daily check should be performed to ensure that the rock wool is moistened.
3. Root Riot Spread Tacos
Root Riot’s propagation plugs are made of a sponge-like material composed of composted organic materials. Its porous structure aids in maintaining the ideal air/water ratio for root development.
They contribute to the proper balance of water, oxygen, and micronutrients. This method of germination produces excellent results. It is used in the same way that rock wool blocks are.
4. Kitchen paper
Cotton is commonly used in place of kitchen paper. It consists of moistening the folded kitchen paper in a container. It is one of the most common methods for germinating seeds.
It is one of the most common ways to germinate seeds of any plant, and it is sometimes replaced by cotton. It entails moistening the folded kitchen paper in a container (for example, a plate). The more paper you add, the more moisture is retained, and the less the paper must hydrate during the process.
When the seeds are moist, they are placed on top and covered with a thin layer of paper (this step is usually forgotten). The plate is then covered with another of the exact dimensions, with a small gap between them to allow the seeds to “breathe.” As with rock wool, we will keep the medium – in this case, the paper – moist at all times.
If the crop is to be grown outside, another option is to plant the seed directly in a pot or on the ground. This is not usually recommended because the seed may remain deeper than it should. We also push the seed deeper if we water after planting.
As a result, the soil must be watered before sowing the seed. It is also recommended to soak the seeds for one day before planting to promote seed germination.
Germinate marijuana seeds step by step
Marijuana seeds can be germinated using:
Germinate seeds in a jiffy (small bags of peat)
The jiffy must first be soaked in water for 15 minutes. When they begin to swell, They are drained slightly, and a 1cm deep hole is made. The seed is placed in this hole, with its crown facing upwards.
You can buy small plastic greenhouses with holes to allow them to breathe. The hole is filled with unpressed peat, and the jiffy is kept dry, warm, and ventilated. However, keep them away from drafts. Usually, seedlings emerge after three days. The plants took three days to hatch using this method.
Germinate marijuana seeds in Rockwool
To begin germinating seeds, we must first hydrate the Rockwool like we do jiffy. The excess water is then drained, and the seed is planted in the same manner as in the jiffy, one centimeter deep with the crown upwards and covered with rock wool. Because rock wool can dry out, we must keep it moistened daily if required. Small greenhouses are highly recommended because they keep the Rockwool moist and prevent it from drying out.
When the seedling emerges, it will be transplanted to our choice’s substrate or hydroponic system. Germination in Rockwool takes about three days on average.
Germinate seeds in Root Riot
Root riot’s seed germination procedure is very similar to Rockwool. Seedlings are born after four days using this method.
Germinate seeds on kitchen paper
To germinate marijuana seeds using this method, we take a couple of kitchen papers and fold them several times.
We moisten the paper in a deep plate or similar container with water. The seeds are then placed on top and covered with a layer of paper.
We use another deep plate with a small hole for air to enter as a lid.
It is frequently used in conjunction with one of the preceding methods. When the seed radicle appears, it is placed instantly, a cube of rock wool or a propagation block. After a few days, the seedling emerges.
Whatever method is used to germinate, specific important considerations must always be considered.
How to Germinate Marijuana Seeds the Easy Way
There are many opinions about how to germinate marijuana seeds.
Some people advocate putting cannabis seeds in between two wet paper towels.
Others say put them in a glass of water.
Such methods force you to handle your seeds when they’ve just sprouted.
The seeds have to be carefully plucked from the paper towels or water, and just as carefully placed into a growing media.
The extra handling creates opportunities for germinated seeds to be damaged.
The simplest methods that work well are always the best methods.
That’s why I germinate marijuana seeds in the media they’ll grow in.
If the final destination for my seedlings is soil, soilless mix, or coco coir, I put the appropriate material in a JiffyPot and water them from the bottom with reverse osmosis water at 6.1 pH.
You may notice it’s impossible to get accurate pH readings on zero parts per million reverse osmosis water.
I add beneficial microbes such as Voodoo Juice, Piranha, and Tarantula until I get enough parts per million to make my pH readings accurate.
The added benefit of using beneficial microbes products is they protect cannabis roots and root zones, and speed up root development.
If the final destination for my marijuana seedlings is a pure hydroponics system such as deep water culture or an ebb and flow hydro system using rockwool, I plant my seeds into a rockwool cube.
Not the smallest size ones either. I like the larger sizes.
Look here for detailed information that helps you germinate marijuana seeds using rockwool cubes.
Note that rockwool must be pre-treated before use to get its pH where you want it.
Look here for instructions on how to condition rockwool.
The best depth for planting marijuana seed is 3/8 th to ½ inch below the surface line.
The best temperature range to germinate marijuana seeds is 74-76°F, but they can germinate up to 80°F. Warmer than that is too warm.
If you don’t have precision temperature control where your seeds are germinating and temps are too cool, you could use a seedling heat mat.
Be careful to control the seed zone temperature when using a seedling heat mat.
It’s best to get a seedling heat mat with built-in thermostat.
Don’t Drown Your Cannabis Seeds
The biggest mistake growers make when they germinate marijuana seeds is overwatering.
The rockwool cube, soil, soilless mix, or coco that you germinate marijuana seeds in shouldn’t be soaking wet.
The media should be totally damp, but not soaking wet.
If the media is too wet, seeds might rot or drown.
If you have healthy seeds, they should germinate in 2-5 days.
Old or inferior seeds can take as long as 10-11 days.
If they’ve been moist that long and haven’t germinated, they’re most likely not going to.
If your seeds are old or otherwise not fresh or reliable, look at this kit that can help them germinate.
As soon as your seeds germinate, put them under a Hortilux PowerVeg lighting fixture, or some other T-5 or low-power LED, for at least 2-3 weeks until you’re sure your seedlings’ root systems and leaf structures can handle full HID, LED, or sunlight.
Rather than using the paper towel or submerse in water methods, this method we’ve given you to germinate marijuana seeds is direct, easy, and doesn’t require you to handle, transplant, and possibly damage a sprouted marijuana seed.

Where to find marijuana seeds ideal for growing in rock-wool?
Here is how rockwool is used in the cultivation of hemp
Many cannabis lovers wonder where to find ideal cannabis seeds for rock-wool cultivation: but are you sure you want to grow marijuana seeds in rockwool cubes? Before you do, there are a few things you should know.
PSYCHO XXL AUTOMIX
First of all, growing cannabis in Italy is illegal: the hemp plant produces inflorescences containing THC, the active ingredient of marijuana, which is illegal in percentages above 0.5%. For this reason, the cultivation of hemp is prohibited, even if it is no longer a criminal offence in case of small cultivation for personal use: what is legal is instead to sell and buy cannabis seeds. But what is the reason?
You should know that weed seeds do not contain THC in themselves and an inactive state is therefore considered in the same way as the common seeds of other types of plants.
The legal problem arises when they are germinated, as they would give birth to a hemp plant that would produce flowers with a high THC content.
So, if you are wondering where to buy marijuana seeds, the answer is in a grow shop, physical or online, such as SensorySeeds, and if you want to germinate them, you take a significant risk. Theoretically, the uses of marijuana seeds in Italy are as follows:
The use of stone wool as a substrate for the cultivation of hemp is a very particular technique and has, like all the others, pros and cons. Let’s see what it consists of and what are the advantages and disadvantages of growing cannabis seeds in rock-wool.
Growing cannabis seeds in rockwool: what is it and what are the advantages and disadvantages of using it
You’ve probably already heard of rock-wool but didn’t know it was also used to grow cannabis seeds and it wouldn’t be so strange if you didn’t have the slightest idea what it is. Rockwool cubes are, contrary to popular belief, an artificial product, created by man to imitate a typically Hawaiian natural phenomenon.
Pele’s hair is basaltic glass filaments born from the volcanic eruption of Kilauea, in the Hawaii islands. Due to the strong wind, the lava solidifies into a filamentous form that resembles blond hair, just like that of the god Pele. Artificially, therefore, this natural process is reproduced, solidifying basalt slag in filamentous form, using air flows, to obtain rock wool cubes.
The advantage of this type of substrate for the cultivation of cannabis seeds is linked to its humidity gradient, capable of retaining and distributing all the nutrients nebulised on it homogeneously. However, rock-wool tends to dry quickly on the surface, remaining more humid on the ground, so it should be continuously monitored.
Another great advantage of rock-wool cubes for growing marijuana seeds is that they can be placed in larger cubes as the plant grows, without disturbing its roots in any way. It will avoid having to move the cannabis seedlings from one pot to another, protecting their good health.
This type of substrate is very often used in professional hydroponic marijuana crops because of the absorbing power of its filaments. However, if it goes well in professional hydroponic systems, it presents risks in the management of home growing, which is legal in some municipalities of Spain.
The absorbing power of the filaments is a double-edged sword: if poorly handled it can lead to overloading of liquids underneath or excessive dryness since in a few hours they tend to slip away. If used outside of a hydroponic system, rockwool should be followed very carefully from this point of view, both to prevent it from staying dry for too long and not to have an overload of nutrients in the plant.
Now let’s see what the main steps are for growing ganja seeds in rock-wool.
Growing cannabis seeds in rockwool – that’s how to do it
As said before, growing weed seeds is not legal in our country, as they would lead to the production of high THC flowers. However, there have been cases where the law allows the home growing of marijuana for personal use, as it happens in some cities in Spain.
If you were to choose to grow marijuana seeds in rockwool cubes, you would first need to know how to handle this type of substrate. While it has a high absorbency power, it also has a rapid “slip” of liquids underneath, which you should keep under control to avoid nasty surprises.
First of all, you should know that rockwool has an average pH of 7, which is too alkaline to grow cannabis seeds, so it needs to be treated before using it. What you need to do is to soak the rock-wool cube in a nutrient solution with pH at 4.5 and CE (electrical conductivity) at 0.4-0.5, to stabilise the PH of the cube properly.
To be sure that you have obtained the appropriate value for growing marijuana seeds, the cube must be soaked in a nutrient solution with pH 5.5 and the PH of the runoff from the filaments measured: if it remains the same, it is ready. On the contrary, if it is still too high, it will be useful to re-immerse it in the first solution for a few hours and then redo the test until the desired PH is reached.
Once this is done, you can finally place the cannabis seed in the rockwool cube, after having previously soaked it in warm water or moistened it in the previous 24 hours using absorbent paper, all strictly in the dark. Once activated, in a few days the maria seed will hatch and the first cannabis bud will be born, which will soon open its cotyledons, the first two round leaves, and will harpoon its rootlets to the filaments of the cube.
As soon as the seed is placed in the rock-wool, it will be useful to keep it at a constant temperature of 20°-25°, which can be obtained if necessary, with a suitable lamp, lit above the cube. Maintaining humidity is very important, so unless you have created an automatic hydroponic system, you will often need to check the level of impregnation of the stone wool cube.
Once well rooted, the hemp seed can be relocated, without having to extract it from the first one, in a larger rockwool cube, previously treated as we have seen before. At this point, the hemp seedlings will be ready to be exposed to artificial light in a cultivation room.
