How to germinate cannabis seeds
So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.
What is germination?
Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.

When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.
It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.
Preparing to germinate cannabis seeds
Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.
The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.
How to germinate cannabis seeds
The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.
How to germinate seeds in soil
Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.

First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.
Place the soil in a small pot and use your finger or a pencil to push a small hole in the dirt, a bit more than half an inch deep. Insert the seed into the hole and bury it with soil. From this point on, don’t touch your seed. The young plant is fragile and knows how to position itself in the soil bed.
Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.
Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.
When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.
How to germinate seeds in water
You can also germinate your seeds by placing them in water. It’s slightly faster than the soil method, but you need to adjust your environmental factors accordingly. Remember, successfully germinating seeds requires a perfect balance of ideal growing conditions. When germinating in water, seeds need only 24-48 hours to pop their stems, though cultivators can keep them soaking for up to a week as needed. Water germination is faster because the seed gets all the moisture it needs immediately, and the shell softens and cracks more easily after soaking.
To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.
The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.
The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.
How to germinate seeds using paper towels
The paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.
To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.

Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.

The paper towel method also has its risk, as the fragile seedlings can be damaged during the potting process. The tiny roots can also get tangled in the paper towels, so make sure to move the seeds to potting soil before roots grow too long. Use your hands or tweezers to gently remove each seed from the paper towels and place them in a prepared growing medium.
How do you germinate seeds indoors?
Whether you’re planning an indoor cultivation or outdoor grow, it’s best to germinate your seeds indoors. It’s easier to maintain proper temperature, light exposure, and moisture inside, and you can protect your seeds from the elements. Indoor germination, whether using soil or paper towels, will ensure your cannabis seeds have the best chance for survival.
To germinate seeds indoors, use any of the methods described above. Within a few days, you’ll have popped seeds ready to transfer to a growing medium.
Do you need to germinate seeds before planting?
While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.
Once your seeds have sprouted roots, they should be planted in soil, a soil-less medium, or in your hydroponic setup. Make sure not touch the root, caring for and navigating the seedling so that the roots face downward. Plant the seed about one inch deep in your growing medium, cover lightly, and allow for about a week for the seed to emerge from the soil. If the seed hasn’t poked through by day ten, it likely didn’t survive.
How to germinate cannabis seeds in paper towels
Cannabis seeds are surprisingly hardy little things, and there are dozens of ways to successfully wake them up and make them grow. However, if you’re now nervously fiddling with the first pack of beans you’ve ever bought, you want the simplest and most reliable method, right? This is to germinate cannabis seeds using paper towels.
Germinating cannabis seeds in paper towels is as easy as wetting the towel, squeezing out the excess water, and placing one or several seeds between two layers. After that, you should only make sure that the towels don’t dry out and stay in a dark warm place until the taproot appears.
Step 1. Buy Good-Quality Cannabis Seeds
Trying to make old seeds germinate can be a nightmare for a first-time grower, so buy fresh, viable seeds from a reputable seed shop such as Herbies.
Step 2 (Optional). Use Hydrogen Peroxide
Water is the only thing you really need for sprouting weed seeds in wet paper towels, and if you’re a novice, you probably should stick to the basics. After all, the more complicated the process, the more room for mistakes. On the other hand, using a weak solution of hydrogen peroxide (H2O2) in place of plain water will kill any infection that may lurk on the surface of seed shells.
Pharmacies sell a 3% solution of hydrogen peroxide, and you’ll need about 0.5-1%. So, water the solution down by mixing one part hydrogen peroxide with five parts water. If you’re confident you can mix a solution of the required strength, go ahead. As an added bonus, according to research. using H2O2 increases the speed of germination in the first 24 hours.
Step 3. Wet the Paper Towel
Use water of drinking quality. If your tap water is chlorinated, it’s not the best option for starting marijuana seeds in a paper towel. Let it sit overnight so that chlorine evaporates.
Wet your paper towel and then squeeze out the excess water. The towel should never be dripping wet, just thoroughly moist.
Step 4. Place Your Seed(s) Between Layers of the Paper Towel
The secret to the success of paper towel germination is that layers of paper surround the seed from all sides, creating the perfect environment for sprouting. It provides enough moisture to seep in through the shell and ‘turn on’ the embryo inside, and there’s enough oxygen for the seed not to suffocate.
Hint: If you grow seeds of different varieties, label the strains from the start.
Step 5. Place Everything Between Plates
Don’t let the moisture evaporate before the germination takes place. The easiest way to ensure this is to place the paper towel between plates and put them in a dark warm place, such as a kitchen drawer. Darkness and warmth are essential because this emulates the seeds’ natural environment – the moist soil in late spring.
Step 6. Check Your Pot Seeds Every 12 Hours
When germinating cannabis seeds in paper towels, you want to plant them as soon as they show taproot. Some growers prefer that it reaches about a half-inch (1cm), but it usually needs just a few hours after cracking to grow this long. You may want to do the first check after 24 hours and then every 12 hours after. Good viable seeds usually take no more than 48 hours, with a germination rate of above 90%.
What to Do After Seeds Germinate in Paper Towels
When you germinate pot seeds using the paper towel method, you have the advantage of knowing within the first day or two that your seeds are not duds but very alive and healthy. Then you can breathe out and put your germinated beans in the medium of your choice.
Place the seed half a centimeter (a quarter of an inch) deep into the medium (soil, coco, jiffy plug, rock wool, etc.) and cover it with more medium. Make sure it’s moist but not soaked with water. At this point, you may start to monitor the pH. It should be around 6.0-6.5 for soil and 5.5-6.0 for soilless mediums. The correct pH levels will help your seedling with absorbing the nutrients.
As soon as the seedling shows above the surface, it needs to receive light. You may also want to help it shed the shell by wetting and gently removing it with tweezers or your fingers.
How long does it take to germinate cannabis seeds using paper towels?
Depending on the quality of the seeds and whether they’re fresh or old, it usually takes about 12-48 hours for most seeds to germinate. In extreme cases, it could take up to 7 days, but then there’s no point waiting. In this situation, learn about the tricks of making old seeds germinate.
When to transplant seeds from paper towels?
You can transplant germinated seeds as soon as they crack and their taproot is visible, but you might want to wait for several hours more so that the taproot grows to something like 1cm (half an inch). After that, there’s no point in delaying the transplant.
What to do if seeds are not germinating in paper towels?
If you have trouble germinating seeds, check the conditions. Paper towels should be moist, the seeds should be kept in darkness, and the temperature should be reasonably warm – around 25°C (77°F). Of course, weed seeds can germinate well outside this range, let’s say 18-28°C (65-82°F), but the speed and success rate won’t be as good with temperatures too warm or too cold. If the conditions are fine but the beans still fail to sprout, maybe the shell is too hard for moisture to seep in. This happens a lot with old seeds that have dried out too much. Use sandpaper to scarify your seeds or very gently crack them along the seam. Then repeat the whole germination process.
How to germinate with the paper towel method
Daily we reveive the questions like “what is the best way to germinate” or “how do I start germinating”, We know this is for lots of people not an easy thing said…. So we tought to make it as a subject in the next weeks
First of all we want to say there are really a lot of ways to germinate seeds and each one definitely has his/her best way for a 100% succeed …
Germinating with Kitchen paper and tupper
This is a pretty easy way to do it, you only need a vacuum closeable tupper or what you can find in the kitchen to keep things vacuum, then you take the kitchen paper and you fill the bottom of the tupper with a layer of the paper, then you spray the layer with water from around 23 degrees Celcius until it is wet but not soaken wet .Then you take the seeds and put them slowly and careful on the wet layer with each a good distance between the seeds so they can´t get strangled .then you put another layer of kitchen paper above the seeds so they all are covered and then you also spray this layer wet, but again not to wet (this all to avoid rotten or mold) .You close the tupper and you put it in a total dark place with a temperature around 21 to 24 degrees Celcius.In around 36 to 72 hours you will see the seeds are popped and they can go in to soil for further rooting and growth .
Under here we show you a video tutorial how to do it .
