How to Germinate Cannabis Seeds
An in-depth guide on how to germinate cannabis seeds. Discover different techniques on how to germinate marijuana seeds to ensure a successful cannabis crop.
Everything has a beginning.
Cannabis seeds, like all seeds, must undergo the germination process before it can grow into a weed-yielding beauty.
Countless cannabis germination guides litter the internet. However, none go as in-depth as our seed germination tutorial. Read along to learn how to germinate marijuana seeds like a pro.
You’ll discover everything you need to know about the art of germinating marijuana seeds. From the necessary equipment to different germination methods and everything in between, we’ve got you covered.
The Chemistry Behind Cannabis Seed Germination
Cannabis seeds require the right conditions to sprout.
Without the proper temperature, moisture level, or oxygen saturation, weed seeds will not germinate. Although you can readily germinate seeds outdoors, nothing beats controlled germination indoors.
Let’s take a look at the three primary elements that influence the germination rates of marijuana seeds.
Water is the key player in the process of germinating marijuana seeds.
The outer-layer of the cannabis seed acts as a protective casing that provides a two-fold defense — prevent damage to the inner embryo and prevent minimal moisture from premature germination.
However, if the marijuana seed is saturated with water, it will eventually absorb the moisture and kick-off the germination process.
Once the embryo activates through water saturation, it requires oxygen to jump-start the respiration process. Oxygen fuels respiration, which unlocks food stored within the embryo.
After the respiration process, the embryo consumes the food stores, which in turn produces energy. Energy is the necessary product that propels the germination stage onwards.
Even if cannabis seeds have access to water, oxygen, and energy, it’s all for nothing unless it has access to warmth.
As long as cannabis seeds experience 72-78°F during the initial germination process — they’ll burst forth from the ground and spread their primordial leaves under the sun or artificial light.
The three most important elements for successful weed seed germination
Why It’s Important to Germinate Weed Seeds Indoors
At its core, the germination process lays the foundation of cannabis plants.
Overall, marijuana plants will underperform without proper germination techniques compared to those that experienced ideal conditions during the germination process. Therefore, it’s always best to harness an indoor environment when germinating marijuana seeds.
What to Look For Before Germinating Marijuana Seeds
Before you begin the germination process, there are a few things you must look for.
Let’s take a brief look at each.
Damaged Marijuana Seeds
Ordering feminized or autoflowering cannabis seeds online is the best way to acquire top-shelf genetics.
The seeds, however, may experience a few bumps on the road during the shipping process. With this in mind, you must look over each seed to ensure there isn’t any damage.
As long as each weed seed is undamaged, the germination process will be smooth.
The Cannabis Seed’s Age
Next, it’s a good idea to write down the date on each seed pack once received.
By doing so, you’ll have a clear understanding of a seeds’ age. Like all things, cannabis seeds lose their luster as the years go by. Cannabis seeds may remain viable for decades. However, germination rates decrease over time.
Therefore, you should only germinate seeds that are properly stored for a maximum of 6-months.
The Cannabis Seeds Color
Lastly, you must check the cannabis seed’s color.
Cannabis seeds come in different sizes and exhibit various markings across the outer seed coat. However, the seed’s color is an excellent indicator that represents seed maturity.
In other words, light green to pale white seeds are immature and are likely unviable. Therefore, always make sure that your cannabis seeds are light to dark brown color before germination.
Take a close look at the seeds that you receive for damage or discoloration
Should You Use a Seedling Heat Mat?
Many new cannabis cultivators ask if they should incorporate a seedling heat mat into the equation.
Although seedling heat mats are excellent tools to ensure fast germination, they are not always necessary. Seedling heat mats work by producing a gentle warmth that won’t rapidly dry cannabis seeds during the germination process.
However, they may be overkill if you utilize them during hot days, such as those during the summer months. Alternatively, they are essential during colder months during the winter. Therefore, you can choose to harness a seedling heat mat based on the time of year that you choose to germinate marijuana seeds.
Three Easy Methods To Germinate Cannabis Seeds Indoors
Now that you have a broad understanding of germinating marijuana seeds let’s get some weed seeds poppin‘ with a few different step-by-step tutorials.
You’ll have a better idea of which germination technique to choose once you’re done reading this section.
1. How to Germinate Marijuana Seeds in Soil in Five Easy Steps
If you want to germinate weed seeds au natural — there’s no better option than using soil.
Here’s a list of what you’ll need to germinate cannabis seeds in soil:
- Feminized or autoflowering cannabis seeds
- Eco-friendly “starting” container
- Heat mat (optional)
As you can see, the list above isn’t extensive in the least. In other words, germinating marijuana seeds in soil is incredibly affordable.
First, fill an eco-friendly starting container with soil.
The golden rule? Don’t pack down the soil. Remember, the soil you choose must exhibit a loamy consistency. Hardpack soil does not allow proper water drainage and oxygen circulation, which, as you learned previously, are critical components for the seed germination process.
Furthermore, if you choose to use a heat mat, place the eco-friendly containers on top to warm the medium adequately.
Label each container.
The last thing you want to do is forget what seed you placed into each container — especially if you’re germinating multiple cannabis strains at once.
Now, it’s time to sow the cannabis seed.
Create a small hole that’s roughly 0.25-inches (6mm) deep. Gently place the seed inside the hole and cover it. It does not matter which direction you put the seed — believe us when we say that the seed and gravity will sort things out.
It’s important to note that each eco pot should contain a single cannabis seed.
Gently pour a small amount of water into the area where you buried the cannabis seed.
At this point, you must ensure that the cannabis seed never dries out. Once the germination process begins — there’s no turning back. Therefore, allowing cannabis seeds to dry will guarantee inadequate germination or premature death.
Ultimately, you must monitor the soil and continuously apply water until the seed sprouts.
The final step is patience.
The moment the seed is planted, most beginners ask: how long does it take to germinate cannabis seeds, or how can I germinate my seeds fast?
Healthy cannabis seeds typically break the surface within 2-4-days. Older seeds, however, may take upwards of 12-days to sprout.
The germination phase is an incredibly vulnerable moment for cannabis seeds. Therefore, Do not — we repeat — do not dig up the seed to “check on it.”
This is what you can expect after you successfully germinate your cannabis seeds in soil
2. How to Germinate Marijuana Seeds Using Paper Towels In Five Easy Steps
One of the most popular germination techniques is the paper towel method.
Here’s a list of what you’ll need for this low-budget method:
- Feminized or autoflowering seeds
- Dinner plate
- Paper towels
- Spray bottle
- Heat mat (optional)
Now that you’ve gathered the necessary supplies let’s get crackin‘.
Place two to three sheets of paper towels on top of a clean dinner plate. If you decide to use a heat mat to increase the temperature, place it under the dinner plate.
Label the dinner plate with the name of the cannabis strain of choice.
Place up to 10-seeds per plate.
You must make sure that a minimum of 1-inch adequately separates the seeds.
Spray water on the seeds until the paper towels are completely saturated. Once done, place a new layer of 2-3 paper towel sheets on top of the seeds. Use the spray bottle to soak the new paper towel addition.
Remember: the paper towels must always remain saturated with water. If allowed to dry, the cannabis seeds will fail to germinate.
The germination process should occur within 24-48-hours. After 48-hours, gently peel back the upper paper towel section. If the seeds germinate, you will see cracked-open seeds with an emerging radicle.
At this point, it’s time to move the germinated seed to its new home with a pair of tweezers. This final step requires extreme care because the radicle is fragile, and if broken, the embryo within will die.
Be careful when you use the paper towel method and make sure to label each plate
3. How to Germinate Marijuana Seeds Using Rooting Cubes in Five Easy Steps
Germinating weed seeds with rooting cubes is the ideal method for beginners and professionals alike.
Overall, rooting cubes provide the ease of the paper towel method and the soil technique’s efficiency. Let’s take a look at everything you need to when germinating marijuana seeds with rooting cubes.
- Feminized or autoflowering seeds
- Rooting cubes
- pH 6.0 water
- Rooting tray
- pH meter and pH up or down
- Heat mat (optional)
First and foremost, place the rooting cubes in the rooting tray. If you decide to use a heat mat, place the tray on top.
Next, label each rooting cube or tray with the appropriate name of each cannabis strain.
Use a pH meter and pH solution to achieve a pH of 6.0.
The amount of water you pH depends on the number of rooting cubes. Start with one cup of water if you are germinating less than ten seeds.
Germination cubes require a pH of 6.0 because they are typically made from peat moss, rockwool, or other soilless-based mediums. Therefore, a pH of 6.0 will ensure the best possible results once the seed germinates.
Each rooting cube is equipped with a pre-made hole.
Place one cannabis seed per hole. You may tear off a small piece of the substrate to cover the opening. Once done, saturate the rooting cube with pH 6.0 water.
You must make sure that the rooting cube never dries out. Remember, cannabis seeds must remain moist until they sprout to the surface.
Once again, patience is the final step when you learn how to germinate cannabis seeds with rooting cubes. Overall, cannabis seeds may emerge from the rooting cube within 2-4-days. However, germination may take as long as 7-days.
There are a lot of rooting cubes to choose from, but the germination process remains the same
How to Germinate Old Cannabis Seeds
Now that you understand how to germinate healthy cannabis seeds let’s quickly discover how to germinate old marijuana seeds.
As you become infatuated with the world of cannabis, you’ll soon begin to stack an extensive seed collection. Don’t worry; we’re all seed hoarders at heart because there are so many incredible cannabis genetics out there.
Eventually, however, you’ll notice that you have more than a few old cannabis seeds. Luckily for you — all is not lost.
Here’s our tried and true technique to give your old seeds a boost during the germination process.
Cannabis Seed Scarification
Scarring cannabis seeds is incredibly simple.
All you need is a nail file or a piece of sandpaper. Use the file or sandpaper across the surface of the seed in question. You do not need to use an immense amount of force, but instead, a few good scrapes to scar the seed’s outer shell will do.
The point of seed scarification is to allow water to penetrate the seed coating easily. By doing so, the embryo receives a jump start that initiates the germination process.
Once the seeds are scarred, you may choose one of the three above mentioned techniques to complete the germination process.
A few readily available tools to get your cannabis seed scarification done
The Best Way To Germinate Marijuana Seeds
Now that you’re done reading this guide on seed germination — which method will you choose?
The soil, paper towel, and rooting cube methods are all tried-and-true and provide excellent germination rates. Remember, cannabis seeds are an investment, and you must use the best germination method possible to ensure a healthy cannabis crop.
You have one chance to germinate each seed the right way, and by using this guide, you’ll make each seed count.
The best way to germinate cannabis seeds!
With this guide, we would like to explain to you, how to germinate a cannabis seed most successfully. There are three common methods of cannabis seeds to germinate. Properly executed, they will be successful in almost every case.
- Germinate hemp seeds directly in soil
- Activate cannabis seeds with water
- Germinate cannabis seeds in damp cloths
So that cannabis seeds can be germinated under optimal conditions, in all three breeding types, some basic rules have to be considered. Before we describe the methods exactly, we first want to talk about these basics; The first golden rule is for example, not to treat cannabis seeds with bare hands to avoid the chance of contamination with bacteria or fungus. We strongly recommend the use of clean gloves and some disinfected tweezers!
Germinate weed seeds – The quality of the water:
The water temperature should be around 20 degrees and have good quality. The quality of the water can be tested with a PH meter and an EC meter. Recommendation: Osmosis water or drinking water very debil (with little salts and mineral arm).
The ideal substrate to germinate weed seeds:
You can work with different substrates. The most common are earth (light mix), coco and rock wool. Even with the substrates, the soil and ambient temperature should be right. A light mix is specially adapted to sensitive plants such as hemp. Most mixtures contain nutrients and minerals for a few weeks, which the young plant absorbs when it needs them.
For Coco substrate, before working with it, you should test the EC content, as most Coco substrates have a very high value. To lower the value, wash the Coco once with mineral water (osmosis water).
Breeding for coco and rock wool is also referred to as hydroponic cultivation, which means that significantly more air circulation at the roots is created. But the nutrients that are then fed to his plants are more directly absorbed by them. The risk of over or under-fertilization is greater but also the expected yield. Breeding on hydroponics is what gardeners with more experience.
Required air, light, and temperature for germination:
In order not to endanger the germination capacity of the seed, it should be stored in a dark and cool place (6 ° – 10°).
Before the seed is germinated, it must not be exposed to light and the air temperature should not be below 20° C (68° F) nor exceed 30° C (86° F). Maintaining a temperature around 25°C (77° F) is ideal. For outdoor cultivation, it’s recommended to germinate indoors, letting the seedlings grow for a few weeks, and don’t set plants outside too early.
Method 1. – Germinate hemp seeds in soil
- Prepare material (fill small flowerpots with soil).
- Lightly moisten the potting soil with good water. (Too much moisture = mold and fungal danger).
- Place the seeds in a 0.5cm recess in the center of the pot. Make sure that the seed is transverse and not upright, this can affect the germination rate. Nature has not shaped the seed without reason oval. If you set the seed transverse, it will easily position itself properly in the soil after germination! When you work with jiffies it works something similar. The jiffy is only soaked in water until it swells apart, then the water is expressed again without crushing it until residual moisture is over. At Jiffy, the factory usually prepares a slight depression for the seed.
- Lightly cover the seed with soil so that no light can shine directly on the seed. Also with the jiffi one covers the seeds with a little material. Wet but not wet! Now pour no more that could flush the seed back up and the amount of water is also difficult to control.
- In case of too little moisture, we recommend wetting the plant with a spray bottle.
- Now put the plant in a safe place and depending on the variety and genetics can be expected in the next 36 to 72 hours with a first result. In some cases, it can take up to 6 days.
Method 2. Germinate cannabis seeds in a paper towel.
- For preparation, we gonna need two plates, some sheets of kitchen roll, good quality water as described above, and our seeds.
- Put two sheets of kitchen paper on one of the plates and moisten them with water.
- Put your seeds on the damp cloth and put two more kitchen towels over it.
- Moisten also the upper cloths. Runoff excess water that the wipes are only slightly saturated.
- Put the second plate on the other plate like a shell.
- Store in a dark place and check daily that do not dry out the kitchen towels and of course to see if the seedlings are already broken. Once it is germinated, a small white shoot comes from one side. Now the time has come, the seed can be placed in the substrate of your choice. Carefully remove the seeds with tweezers from the cloths and carefully place them diagonally with the small germ downwards into a prepared hole. Only so deep that the seed is slightly covered with soil (max 5mm).
7. Wait, wait, wait and then be happy.
Method 3. Germinate cannabis seeds in a cup of water
This method is particularly suitable for activating seeds that have been stored for a long time
The addition of hydrogen peroxide is suitable for softening the husk of the hemp seed. About 3 – 5 drops per 100 ml of water are sufficient.
- Prepare a cup of water at a temperature of about 12 degrees Celsius (54 degrees Fahrenheit).
- Put the seeds into the water for 12 hours.
- Prepare to plant the seed in a small flower pot. Exactly as we described in method 1, under point 3.
- After planting, cover the seed with the substrate and moisten again with water.
- After about 2 – 3 days, the germ should gradually see daylight.
Cannabis seeds do not germinate? These are the most common mistakes:
- The pH of the water is too high or too low. Regardless of the method used to germinate the cannabis seeds, the pH should always be between 5.5 and 6.5.
- The EC value of the water is too high, it should be below 0.8.
- The water temperature was ignored, it should be between 20 ° and 22 ° celsius.
- If you let the hemp seeds germinate into soil, it may be that too much water was used, the soil was fertilized too much, or that the seed was pushed too deep into the soil, or was placed upside down.
- The seeds were exposed to strong temperature differences during transport.
This information is only of interest to customers who live in a country where cultivating and cultivating cannabis seeds is not a violation of the law.
Understanding pH and How It Affects Cannabis Plants
In the world of cannabis growing, pH affects and is affected by everything. Indeed, the entire process of growing plants is a study in the physical dance of pH balance. Read on for an in-depth overview of pH as it relates to growing quality cannabis.

Biochemistry – Genetics – Molecular Biology – Microbiology
While it can be a daunting topic to try and wrap your head around, understanding soil pH is key to growing healthy cannabis plants. In this article, we’ll outline all you need to know about soil pH and how to get it right when growing weed.

What Is Soil pH?
pH is a measure of how acidic or alkaline something is. The pH scale ranges from 1–14, with a pH of 7 being neutral (the pH of pure water). If pH is lower than 7, a substance is considered acidic (think vinegar or lemon juice). If the pH is higher than 7, the substance is alkaline, as is the case with soaps, bleach, and ammonia.
In more scientific terms, pH level has to do with the concentration of hydrogen ions, say in the water you give to your plants. The pH scale is logarithmic to the base 10, which means that water with a pH of 6 is already 10x more acidic than water with a pH of 7.
Below is a basic chart of the different pH levels of common items:
1.0 – Battery acid 2.0 – Lemon juice and vinegar 3.0 – Orange juice and soda 4.0 – Tomato juice 5.0 – Black coffee and bananas 6.0 – Urine and milk 7.0 – Pure water, not tap or bottled water
(the pH running or bottled water can vary considerably)
8.0 – Seawater and eggs 9.0 – Baking soda 10.0 – Milk of Magnesia and the water of the Great Salt Lake, Utah
Why Is pH Important When Growing Cannabis?
So, you now know what pH is. But how exactly does the pH of your growing medium affect the growth and health of your plants?
As you already know, all plants require nutrients for healthy growth. They require the macronutrients nitrogen, phosphorus, and potassium, as well as micronutrients and minerals including calcium, magnesium, iron, copper, and a whole lot more. If plants cannot access these nutrients, it will lead to deficiencies and other serious health problems.
The issue with cannabis plants is that they are only able to take up nutrients within a small pH window, which ranges from about 6–7 when growing in soil. If the pH is lower or higher than that, the plant cannot take in nutrients, even if they are present—thus spurring nutrient deficiencies via “nutrient lockout”.
In those places where cannabis thrives in the wild, the soil is normally slightly acidic; therefore, homegrown cannabis plants also prefer a slightly acidic environment. However, the way that you grow cannabis also plays a role in the optimal pH level for your plants. Cannabis grown hydroponically or without soil needs an even lower pH than a soil grow.
The Benefits of Maintaining the Perfect pH
The benefits of caring for and maintaining your plants’ pH is pretty straightforward; you’ll have healthier plants that demonstrate more vigorous growth and, as a result, produce better harvests. Plus, you’ll also ensure that the time and money you’ve spent fertilising your plants is paying off.
By regularly checking the pH of your growing medium, you’ll be able to ensure that your plants are able to take up all the nutrients you’re giving them. You’ll also be able to catch any pH imbalances early, minimising your risk of running into nutrient deficiencies later on in your grow (more on that below).
The Problem With pH Imbalances
pH imbalances are one of the most common causes of nutrient deficiencies in cannabis plants. As we mentioned earlier, cannabis plants can only take up certain nutrients within a small pH window. If the pH of your medium shifts below or above that ideal window, your plants won’t be able to take up the nutrients in their fertilisers and will start to show signs of a nutrient deficiency.
Understanding and Preventing Nutrient Lockout
Nutrient lockout (sometimes referred to as “nutrient lock”) occurs when your cannabis plants can’t absorb nutrients from the soil or the fertilisers you’re using to feed them. One of the primary causes of nutrient lockout is pH imbalance, but it can also be caused by salt buildup near the root zone as a result of feeding with mineral fertilisers (which tend to have a high salt content).
The Best pH for Growing Cannabis
We’ve alluded to it already, but the best pH for growing cannabis resides within a narrow window. But, within that window, is there an optimal reading you should try to achieve? And, does that reading change depending on how you choose to grow? Let’s explore further.
Soil pH range: 6.0–7.0
If you grow in soil, the optimal pH level for the root zone is between 6.0 and 7.0. However, there is no set number within this range that is “best”. Instead, it can be good to allow for some natural fluctuation within this window to support optimal nutrient uptake.
So, as you adjust, try a slightly different reading each time. You can, for example, adjust your pH to 6.2 for one watering, then 6.6 the next. As long as it stays within 6.0–7.0, you should be fine. Soil is also more forgiving when it comes to pH imbalances, but it can only give so much.
If you grow purely organically—where you do not administer mineral nutrients—pH is less of an issue. If you’re using amended or composted soil with organic matter, the microorganisms within will make the nutrients more available to the roots. However, most growers using standard potting mixes and mineral nutrients will indeed have to reckon with pH.
Go Organic and Forget About Measuring pH
At RQS, we’re big proponents of organic cannabis growing; not only because it delivers a far superior product, but because it takes some of the hassle out of growing, especially when it comes to pH.
While using chemical nutrients might seem simple, it can actually take some time and practice to get the hang of properly fertilising your cannabis plants with liquid mineral fertilisers. Organic nutrients, on the other hand, naturally promote the health of your plants by supporting the development of healthy microbial life within your medium.
Using natural fertilisers like compost, worm castings, and bone meal creates a breeding ground for healthy bacteria and fungi that keep the conditions of your soil optimal, so there’s usually no need to monitor the pH of your soil as closely as you would otherwise.
Hydroponics and Soilless pH range: 5.5–6.5
Hydro and soilless grows are a different beast when it comes to pH. If you grow soilless, say in coco, the optimal pH level at the root zone should be somewhat lower than in soil, between 5.5–6.5. The same goes for all methods of hydro.
With these methods, it is just as important that you allow the pH level to fluctuate across the acceptable range to support nutrient uptake. For example, in hydro, calcium and magnesium are mostly absorbed at pH levels above 6, while other nutrients like manganese prefer a slightly lower pH.
Then again, this shouldn’t be an issue since pH levels will naturally fluctuate slightly with each feeding in a hydroponic setup. You will only need to correct if the pH level exits the optimal 5.5–6.5 range.
When growing in coco, perlite, or hydroponically, you are in charge of administering nutrients directly to the root zone via the water, which means huge pH fluctuations are more of a risk than in soil. The inert media used in hydro and soilless grows merely retains water and provides support for the roots. So, when administering nutrients, be careful that you don’t overload your plants.
How to Test Cannabis Soil pH
Managing pH level means testing the water or nutrient solution and adjusting it accordingly. This may sound complicated, but it really isn’t.
To test pH, you can use a digital pH meter or a pH measurement kit with drops. Opinions here differ as to which method is “best”. Some prefer digital pH meters because they are accurate and easy to read, while others like the drops as they are super simple and don’t require calibration. Try them both and see which you prefer.
Cannabis pH — FAQs
Let’s break down some of the most common questions related to cannabis pH. Feel free to refer to these if you encounter any pH-related issues during your grow.
Questions & Answers: Ph
Do I Test the pH of My Fertiliser Before or After Adding My Nutrients? Always measure the pH after you add any nutrients or amendments as they will change the pH value of your water. After you mix your nutrient solution, use a pH meter or drops to test its pH level.
If you are growing hydroponically, test a sample from your water reservoir a few minutes after you add your nutrients. Do I Need to Measure the pH of My Runoff After Feeding My Plants? Yes. Always remember to test the pH of your nutrient runoff as this will give you an idea of the pH of your medium. How Exact Do I Need to Get My pH Levels When Growing Cannabis? Don’t get flustered if your nutrients are slightly below or above the optimal conditions we mentioned above. Only react to big changes in pH that may inhibit your plant’s ability to uptake nutrients.
Measuring pH With Drops
pH measuring kits usually contain a test tube, a bottle of testing solution, and a colour-coded pH chart. Testing the pH of your soil with these kits is super simple:
- Prepare your fertiliser as per usual and stir it gently. Be careful not to over oxygenate your fertiliser as this may throw off your pH reading.
- Half-fill your test tube with your fertiliser and add 3 drops of testing liquid into it.
- Gently shake the test tube to mix the pH testing solution with your fertiliser.
- Use the colour chart to read the pH of your fertiliser and, if needed, use pH up/down products to adjust it.
- Repeat this process with the runoff from your fertiliser. If the pH reading from your runoff is far below or above that of your fertiliser and in the danger zone (below 5 or above 7), you may need to regulate the pH of your soil.
Measuring pH With a Digital pH Meter
Measuring pH with a digital pH meter (like our pH tester) couldn’t be any more simple. After you’ve calibrated your device, simply stick it into your fertiliser, runoff, and soil to get an accurate reading of the pH in your garden.
