How to Germinate Marijuana: Germinating my Cannabis Seeds for my FIRST GROW

In this video from my first time growing cannabis, I show you how I germinated my cannabis seeds using the paper towel method.

My seeds are from Growers Choice and are all photo-period.

How To Germinate Cannabis Seeds

  1. Soak your seeds in water for 12-20 hours (dark, warm)
  2. Place seeds in a folded, moist paper towel (dark, warm)
  3. wait 24 hours
  4. gently open moist paper towel. Plant seeds taproot down

Soaking your seeds in a glass of water is optional, but I see a lot of people recommending it.

In my first and only experience, soaking the seeds made the seeds pop open and start rooting extremely fast.

Many recommendations say to soak for a day and then leave in paper towel for 2 days. My seeds all germinated prior to paper towel. Your results may vary.

How to Germinate Weed Seeds

There are numerous phases of cannabis cultivation that must be completed before you may be greeted with copious amounts of dank buds. You won’t have a plant to harvest unless you can successfully germinate cannabis seeds.

Germination is the process through which a seed sprouts into a new plant. Often known as “popping,” germination is the first step in beginning a cannabis garden.

Picking out good quality seeds

Cannabis seeds may be obtained from a variety of places, although they are most often purchased online. Because there are so many different internet seed sellers, it’s crucial to pick one that you can trust.

Regardless of where you obtain your seeds, it is a good idea to check them carefully before planting. Seeds will germinate in the majority of cases; nevertheless, poor-quality seeds will result in a weaker plant. Unfortunately, you won’t find out until the vegetative and flowering periods are well underway.

When purchasing seeds, make sure they are ripe and have a dark brown color with lighter highlights and a firm feel. You don’t want a seed that feels fresh and seems green, as this suggests that it hasn’t fully matured. Once you’ve got your cannabis seeds, make sure you have enough room for your plants to develop and thrive.

Preparing to germinate cannabis seeds

The act of germination is important in the production of cannabis. Seed germination is the basis of every cannabis plant, and there are actions that can be performed to increase the likelihood of successful popping. Some growers, for example, increase germination attempts by soaking seeds in a compost tea for 12 hours or in a solution of 1 percent hydrogen peroxide prior to planting to eliminate any harmful bugs.

The environment in which seeds germinate has an impact on the final result. There are a variety of germination methods, however, they all require:

  • Moisture is required for the seed to swell and break free from its shell.
  • Minimal intervention to avoid accidentally breaking the fragile structures.
  • Temperatures that are similar to those of spring (between 68-72 degrees Fahrenheit).

A single root will take form in the presence of moisture before gradually growing into the cannabis plant we know and love. Seeds will begin to grow within 12-36 hours of being exposed to moisture under the correct conditions.
The length of time it takes to germinate depends on how great your germination environment is. Even the worst grower can get a seed to germinate, but it will take a few weeks and will, of course, result in a weaker plant.

How to germinate seeds in soil

The most popular and generally effective technique of germinating cannabis seeds is to plant them in the soil where they will be grown. Because the delicate root is shielded by the soil, this approach is ideal for ensuring that immature seeds have minimal disturbance. It is ideal for plants to develop in the most natural way possible.

If you’re going to utilize soil, be sure you have the proper kind. Use seed-starting or potting soil that has been lightly fertilized. It should have a pH level of around 6. This sort of soil contains spores and nutrients that aid the growth of new weed plants. At this point, don’t add any nutrients; potting soil has adequate nutrients for the first 2 weeks of the plant’s existence. If you apply any additional fertilizer, you risk nutritional overdosing and harming your seedlings.

Place the soil in a tiny pot and make a small hole in the dirt with your finger or a pencil, about half an inch deep. Place the seed in the hole and cover it with dirt. Do not handle the seed beyond this stage. Seedlings are delicate, yet they understand how to place themselves in the dirt.

The seed will have a root if it has already germinated. Place the root in a downward position. Spray water onto the soil gently using a spray bottle and place your pots beneath a fluorescent light. Seeds should be kept away from windowsills since the temperature is too fluctuating for germination. The soil temperature should be kept at 72 degrees Fahrenheit.

Every day, keep an eye on your soil and maintain it to stay wet. You should observe small stems growing from the dirt in 4-7 days.

Move your weed sprouts to bigger pots so that roots can spread out comfortably around the time the seedling stems reach 2-4 inches in height.

Germinate seeds in water

Seeds can also be germinated by immersing them in water. It’s a little quicker than the dirt technique, but you’ll have to modify your environment variables accordingly.

The key is to not soak the seeds for too long. The seeds will usually show their tail within 24 to 48 hours, but you may leave them soaking for up to 7 days without fear.

When seeds germinate in water, they sink to the bottom once they’ve been wet. Water germination is beneficial because it ensures that the proper quantity of moisture is present for seedlings to germinate. It can help shatter open the shell, pre-spouting the plant right before your eyes if done for a brief length of time. Water germination speeds up the process by removing the need for the plant to push through the soil.

Fill a glass halfway with tap water and let it sit at room temperature for a few hours to germinate. The temperature should be between 68 and 70 degrees Fahrenheit. Do not include any nutrition. Watch for any changes after dropping 2 or 3 cannabis seeds into the water. Every other day, refill the glass with fresh water while keeping it at the same temperature.

The seeds should begin to divide after 2 to 4 days. You can plant your seeds at any time, but they must be planted after the roots are 5 millimeters long.

Germinate seeds by using paper towels

You don’t have to use paper towels; there are a few other objects around the house that will do the job just as well. You can use coffee filter papers, newspaper, or cotton wool pads as examples.

First and foremost, wet your paper towel. Make sure the paper towel is thoroughly wet before placing it onto a holding container such as a plate or Tupperware. Spread a few seeds across the paper towel. Make sure there are a few centimeters between each seed so they don’t touch.

With a zip lock bag to seal your container. This essentially creates a greenhouse-like atmosphere, allowing your seeds to grow a bit faster. Place your new mini-greenhouse somewhere that will maintain a constant temperature of approximately 68 degrees Fahrenheit while being out of direct sunshine.

You should notice your seedling growing in about a week. It’s time to move them into a dirt container when you notice this. Take your time and use the tweezers; don’t touch them with your bare hands because this might cause them to be destroyed.

Germinate with starter cubes and seedling plugs

Using specially designed starting cubes and seedling plugs is a more creative approach to grow seedlings. Cannabis germination is simple with these plugs. Simply insert the seed in the cube or plug, add water as indicated, and the seedlings are automatically provided with ideal germination conditions. This is one of the most straightforward germination procedures, with little opportunity for error.

Each cube or plug already has a hole in it where you may plant your seed. Simply place your seed in the precut hole and seal the lid with your fingers. Don’t worry, you won’t be able to screw this up. You should be fine as long as the seed gets in there.

Germination of cannabis seeds

The first stage for any grower is germinating the seeds. To achieve best results, we should use healthy, quality cannabis seeds. All seeds from Philosopher Seeds come in labeled packages with a batch identification number, so the product tracking is much easier.

Although seeds do not need much to germinate, we do have to consider a few basic aspects to be successful. It’s kind of a prenatal stage in which the grower has to be very careful to meet the few needs of the seeds during this phase.

What are the needs of a seed to germinate?

First of all, we should state that healthy and viable seeds do not need any type of additive or special handling to germinate.

Germination of a cannabis seed

Basically, seeds need 3 things to germinate:

Cannabis root hairs

Different propagation media for germinating cannabis seeds

These are the most commonly used mediums to germinate marijuana seeds:

    Glass of water: Some growers use a simple glass of water to germinate their seeds. You just have to put them in the water and in few days you’ll see the radicle sprouting. This method works well especially for hydrating the seeds, but we must remember that they can’t be soaked in water for more than 2-3 days, otherwise they may rot. Using RO water is advised, although you can also use tap water (let it set for some hours so it reaches room temperature and all chlorine is evaporated). Once you see the radicle, it is time to plant the seeds in a suitable growing media. Many growers add a few drops of hydrogen peroxide to the water to accelerate the process.

Germination of cannabis seeds on paper towels

Regardless of the chosen substrate, put the seeds about 2-3mm deep and cover them with a thin layer of substrate. Always remember that seeds are living organisms and some of them may be weaker than others. We are especially concerned about customer satisfaction and always encourage you to tell us your experience. Producing seeds is a passion for us!

Grow lights for germinating cannabis seeds

Right after the seedlings start sprouting from the seeds, they need a light source for proper growth.

If you are growing cannabis outdoors, make sure that your plants have enough sunlight for proper development.

Seedlings sprouting under fluorescent tubes

On the other hand, if you’re growing indoors, use fluorescent tubes or CFLs during the first days. In some days/weeks, you can change to MH lamps or LEDs, always checking the temperatures inside the grow room.


There is a method for germinating aged seeds which have lost most of their germination capacity. Although this method is not necessary to germinate our seeds, it can be useful for some of you.

This method implies keeping the seeds at very low temperatures for a short amount of time, and then let it reach room temperature slowly. In this way, we replicate the winter-spring period, which stimulates the germination of seeds. Seeds are kept for 3 days in the freezer, 3 more days in the fridge and 3 more days at room temperature before starting the germination process.

The best method to germinate cannabis seeds

There is neither a miraculous technique to germinate seeds, nor a miraculous method to grow cannabis. Each grower has its own preferences depending on knowledge, equipment,etc. The key point is understanding the needs of the plant.

I’m just starting to learn through trial and error. I’m getting seeds from people who sell, not from seed banks. I’ve been trying about 5 seeds using variations of germinations methods – but the yield is pretty low. For peace of mind, is germination or a sprout guaranteed from every seed?

Hi GreenFramer, thanks for your comment. If a seed has been properly maintained in a cool, dark and dry environment, and all the instructions for germination are followed correctly, there’s no reason for it not to germinate. Reputable seed banks and breeders (like us) will store seeds in a specialised fridge or cold room to ensure the longest life and viability possible. When seeds don’t germinate it’s usually due to inadequate storage conditions or incorrect germination conditions. I hope that helps, all the best!

Regards John

Hi, I planted my Royal Gorilla & Wedding Cake seeds all at the same time, separately, in small jiffy-peat pots. It is winter here in my part of Australia – not so cold ( 10’c overnight low – 19’c Daytime Max) and it is mostly sunny – although where I have had my germinating box sitting only gets a few hours direct sun at present. I have kept all the little pots nice and moist – and just to be safe, I opened the two small vents on the top of the germinating box so that in the afternoon, in the direct sunlight, I wasn’t accidentally roasting the seeds to warm. I had some other seeds growing in the box to, tomatoes, eggplant and beans, which I planted on the same day using the same Jiffy-Pots. – It has been about 2 weeks now – And All of the vegetable seeds have begun to sprout – so the conditions of the germinating box must be Ok. But no sign of any sprouting activity with the Royal Gorilla or Wedding Cake. Maybe around a week ago, I made a small DIY planter pot out of newspaper and filled it with seed raising mixture, then planted a CBD Beyond Diesel seed – and I left this sitting uncovered in the same spot. It just sprouted yesterday. So I have moved my other seeds in the jiffy pots inside on my kitchen window ledge where it gets a lot more sun (Maybe should have done this to begin with!) My question: Is it too late now after 2 weeks of seeing nothing? – Or might I get a pleasant surprise now they are sitting a much more sunnier spot. Can it take this long to see a sprout?? I have kept them moist -and- they were planted correctly at about 1cm with the crown up

ive had my seeds in water for a couple of days, but still unsure if the glass should be in the dark or in light. can anyone ansa, this is my first attempt

Ando 2019-06-29
Hi,I got some seeds ( med Auto kush hindu ) I put them between 2 cotton pads and watered as per info, also had a g3 speed which sprouted almost immediately but transferred it to a clean cut cola can, wrong way round i might add and in normal compost, I over watered and managed to retrieve the seed which still had some tail left, re-planted it in canna grow dirt but as yet no show. The kush seeds 4 off have shown signs of side cracking but I think my conservatory is to hot and not much is happening, have I ruined it all or can I save them clearly a complete novice but other than the heat in conservatory in which the +G3 speed sprouted so quickly I’m not sure what the problem is, pls help..thanks

Dani 2019-07-04
Hi Ando, About the G3 seed, I’m afraid the only thing you can do now is cross your fingers and hope she’ll make it! With regard to the Auto Kush seeds, it’s advisable to replace the cotton pads every 2-3 days, using new ones moistened with fresh water. You can add a few drops of oxygen peroxide to 100ml of water and use the mix to moisten the pads, you’ll increase germination rates. Best of luck!
