Don’t Learn it the Hardway

A long time ago, as first-time growers, we had no idea what we were doing. It was overwhelming and tempting to skip over this first phase; we were excited for the result, after all.

We had to learn the hard way, but a high-quality seed is only as good as the growing circumstances and the environment you provide.

The germination process is where it all begins.

It turns out that germinating weed seeds isn’t all that difficult.

With a little know-how and preparations, you’ll be well on your way to being a successful parent to a little seedling.

What Is Germination, Anyway?

Once you’ve planted a weed seed, it goes through a period of dormancy. When the seed splits or shows a root, this indicates successful germination. This occurs under specific conditions that involve:

  • Light.
  • Water.
  • Oxygen.
  • Temperature control.

How successful the germination process is depends on the conditions mentioned above. For example, if there’s not enough water, the seed won’t germinate.

Conversely, too much water can virtually drown the seed by restricting its access to oxygen.

When the needs of the seed (see what we did there?) are met, the first thing it does is take in oxygen and water. Its coating will break, or pop, open and a root will emerge.

A single plant shoot then appears to finalize the process.

Such a simple process! Once you have the basics down, you’re ready to tackle that first seed.

Germinating Weed Seeds

From seed to harvest, a marijuana species go through a specific set of steps that ensure a fruitful result.

In brief, they are:

Indoor

  1. Choosing your seed.
  2. Germination: 3-7 days.
  3. Vegetative: 1-2 weeks.
  4. Flowering: 8-11 weeks.
  5. Harvesting/drying: 1-3 weeks.

Outdoor

  1. Choosing your seed.
  2. Germination: 3-7 days.
  3. Seedling: 2-3 weeks.
  4. Vegetative: 3-16 weeks.
  5. Flowering: 8-11 weeks.
  6. Harvesting/drying: 1-3 weeks.

On average, the entire process takes around 3–5 months, sometimes longer, depending on the species and if you’re growing indoors or out. The latter tends to take more time, given the conditions are much less controllable.

Germinate Weed Seeds: Get the Basics Right

Nailing the basics sets you up for a good grow and successful germination from the get-go. One of our primary concerns here is the quality of seed.

What makes a premium weed seed?

  • Color: The best weed seeds will be light to dark brown. Green seeds indicate they were harvested early and/or contain no embryo inside — useless!
  • Texture: Look for seeds that are hard to the touch. Soft, squishy ones indicate they’re not ready for planting.
  • Storage: Any seeds you purchase should be kept at a temperature of around 71-77 ℉ /21-25 ℃

In regards to other conditions, lighting won’t be such an issue just yet, as germinated seeds won’t require it until the root has popped and the first plant shoot has appeared.

You may be wondering if size plays a role as well?

As tempting as it may be to assume the seed’s size is equivalent to how large the plant will be, don’t do it.

For example, a small Sativa seed might turn into a monstrous species once grown.

Germination Methods

Now for the juicy stuff! Today, we focus on five different options to choose from, depending on your needs and available resources:

  • Glass of water.
  • Wet towel.
  • Directly in soil.
  • Stone wool blocks.
  • Using the Spongepot starter kit.

Method 1: Glass of Water

Also referred to as “pre-germination,” this method involves soaking the seeds in water. It’s used particularly for older seeds to try and “wake” them up.

  1. Soak the seeds: Soak your seeds in lukewarm, chlorine-free water overnight.
  2. Float or sink: Seeds that initially float show better chances of surviving.
  3. Check for germination: You’ll see that a white root has “popped” or germinated. This should happen within 1 to 3 days.
  4. Retrieve your seeds: Gently remove the seed and dry it on a kitchen towel.


Pros

  • May be able to revive old seeds

Cons

  • Risky
  • Should only be attempted with seeds that might die otherwise.
  • despite 1 to 3 days being the norm on average, in practice, this can sometimes take up to 7 days.

Method 2: Wet Towel

Similar to the method above, using a wet towel is another pre-germination method.

  1. Wet a paper towel: Do so until it’s completely covered but not dripping.
  2. Fold your seeds inside: Tuck your seeds into the paper towel securely.
  3. Plate it: Place the towel on a paper plate with another plate on top.
  4. Leave in a warm place: Leave for at least a day and up to a week, checking periodically for any popping.

Pros

  • Old seeds might have a chance here.

Cons

  • Seeds may suffer from a lack of oxygen.
  • Mold and mildew might show up.
  • Seeds can become too nimble for a successful transplant.

Method 3: Directly in Soil

This sounds like a more natural method to use. because it is! No fooling around with pre-germination tricks, here:

  1. Use an 8-10 cm/ 3-4 inch pot: Take your pot and fill with seed and cutting soil. Press down.
  2. Make a hole: Use a narrow, pointy object to make a 3-5mm/ 0.20 inch hole in the middle.
  3. Put the seed inside: Place it gently in the hole.
  4. Use chlorine-free water: The soil should be moist but not overly saturated.
  5. Place in a proper location: Find a warm enough area for the seeds to rest.
  6. Find balanced temperature: Too cold and the seeds won’t budge, but too hot and they might dry out. If you’re in a cooler climate, use lighting for warmth. As recommended earlier, 71–77 ℉ /21-25 ℃ is ideal.
  7. Wait three days: It will take, on average, between 3 and 7 days for germination.

Pros

  • Mimics a natural setting.
  • Requires little equipment.

Cons

  • Takes a bit of a green thumb.

Method 4: Stone Wool Blocks

These are the little blocks you’ve probably seen at your local garden shop; nicely organized and packaged for root cuttings and germinating seeds. They’re also perfectly suitable for weed seeds!

  1. Immerse the cubes: Cover them with water with a pH of 5.6–5.8.
  2. Gently squeeze: Do this to wring out any excess water.
  3. Place the seeds: Plant the seeds horizontally within the pre-formed hole.
  4. Cover the hole: Use an extra piece of the soft wool to do this. Make sure it’s not packed too tightly, in order for oxygen to reach the seed.
  5. Choose a warm location: Use the temperature range listed under the soil method above.
  6. Water the cubes: With the same pH as stated in step one, water every 1 to 2 days.
  7. Wait three days: It should take around 3 to 5 for germination to occur.


Pros

  • Similar to a natural process.
  • Easy-to-find supplies.

Cons

  • Cubes may harbor moisture, leading to dead seeds.

Method 5: Using a Starter Kit

A starter kit is a convenient method that gives you everything you need for successful germination. With the Spongepot, you’ll receive a package of 20, 48 or 96 pots to get you started.

The instructions are, more or less, foolproof:

  1. Put supplied bacteria in water: Dissolve the bacteria in a liter of water.
  2. Water the Spongepots: Use the bacteria-water to water the provided Spongepots.
  3. Drain: Drain away any excess water that accumulates in the process.
  4. Plant seeds: Plant one seed per pot, about 3-5 mm/ 0.20 inch deep.
  5. Maintain temperature: Place the Spongepots in a place between 71 and 77 ℉ / 21-25 ℃
  6. Time to wait: Seeds should germinate between 3 and 7 days later.
  7. Transplant the seeds: Once the seeds finish, you can transplant them to their pot to begin their seedling phase.


Pros

  • Easy to use.
  • Includes a soil enhancer.
  • Organic soil mixture with useful fungi.
  • Promotes healthy roots.

Cons

  • Only available through online order.

We at Marijuana Seed Breeders not only care about your seeds but the success of their germination. This gemination method is our favorite! It gives us the highest success rate.

You can see how to germinate with Spongepot in the video below or on the Spongepot product page.

How Long Does the Germination Process Take?

From start to finish, the germination process can take anywhere between 1 and 7 days.

Note that this is an average and the actual time frame depends on the individual seed quality and the growing conditions we discussed earlier.

For example, is the seed large or older? Maybe the temperature is a bit cooler? Seeds with these conditions may take up to more than a week to pop.

Seeds in the ideal temperature range should germinate within a week, maximum.

When Can I Pot My Seedlings?

We understand your predicament. You want to take the best care possible but, at the same time, you don’t want to become impatient and risk the entire process.

The good news is that it doesn’t take long! Once the seeds have popped and you see that root coming through, it’s time to pot your seedlings.

This, of course, will depend on the method you’ve used, but also the state of the seed from the beginning.

Generally speaking, you’ll be ready to do this anywhere between 3 and 10 days after the start of the germination process.

Once your newly-germinated seeds are ready to go in their special medium, you will continue looking over the seedling phase from there.

Depending on the size of your plant, you may need to switch to a larger pot at some point during the process. If this isn’t done, you could experience something called “root bound,” which means the rooting system has grown beyond the pot.

How to tell? Here are some signs:

  • The new growth is fragile and weak-looking.
  • There’s discoloration on the stem.
  • May appear to be underwatered.

Another distinguishing trait to look out for that may indicate your plant is ready for a new pot includes how many leaves your plant has. On average, when plants have around four to five sets of leaves, it’s time for a transplant.

Common Germination Mistakes

When it comes to growing cannabis, there’s a slew of common mistakes that could stop you from achieving a successful grow. More specific to germination, pay attention to:

  • Leaving seeds for too long.
  • Incorrect planting methods.

Leaving Seeds for Too Long

Overestimating your seed’s germination needs could leave you with duds in the end. This is usually the case with pre-germination methods mentioned above, such as the cup or paper towel method.

Leaving your seeds for too long could result in overly sensitive roots that are easily damaged in the transplant process.

Avoid this mistake by transplanting your seeds when the root is approximately one to two centimeters in length.

This ensures the roots are stable but not overly saturated and prone to damage.

Incorrect Planting Methods

We see mistakes being made when it comes to the “two D’s” of direction and depth.

Direction

Placing the seed in its planting medium may seem like an overly simple task. However, there’s still a chance you could screw it up.

Avoid planting it in the wrong direction by paying attention to the seed’s crown.

This looks like a small crater shape located at one end of the seed. The other end has a point, so they’re easy to distinguish from one another.

Make sure that the seed’s crown is facing you when you plant it, which leaves the pointy end facing downward.

This way, when the seed germinates, it’ll sprout properly, sending the root down versus the opposite scenario of resulting in a failed seedling.

Depth

The planting depth matters, too. This will differ depending on the type of seed you’re planting and the medium it’s going in.

Generally speaking, we want to avoid planting seeds too deep, which could result in a seedling never showing up.

The opposite of this, planting too shallow, may also pose a problem. Doing so could result in weak plant stems that may not allow the seedling to grow.

Avoid either scenario by aiming for about 3-5 mm/ 0.1- 0.2inch in depth when you plant.

Germinate Away

As you can see, germinating weed seeds is a basic procedure that if done with a little care and forethought, should be a successful one.

Have a designated location ready that’s warm but not too hot. If you live in a cool climate, use lights for warmth, and make sure your germinating seeds stay wet but not saturated.

It might be tempting to use a pre-germination method, such as the cup or paper towel, but we recommend avoiding these as much as possible.

Using a starter kit, instead, will enable you to have high-quality resources at your fingertips that cover you from A to Z

Pay attention to any root growth or “popping” to indicate germination is complete.

By following our guidelines, you’ll be transplanting your baby plants in no time.

I have a passion for nutrition, organic supplements, and (mental) health. After learning about the beneficial properties of marijuana, I dedicated myself to writing articles that will teach you everything there is to learn about this miraculous plant. I’m looking forward to sharing with people how they can incorporate the benefits of marijuana into their healthy lifestyle: you don’t have to smoke to consume marijuana.

Germinating seeds, how warm water to use and do you keep them in dark?

Just two fast questions about germinating seeds, i’m planning to use the soaking in water -> paper towel method (unless someone knows better methods ofc).

How warm water should i use to do this, and should i keep the glass of water/paper towel thing in dark or light? I read that you should maintain ambient temperature between 68-78f (20-25c) when doing this.

How you guys do it and what’s the success rate? Cheers.

I use very warm water and a splash of peroxide (to kill any fungus or bacteria that may be on the seed)
I only soak for 12 hours tho and keep it somewhere warm around 70 degrees.
I then put them in a paper towel and once again keep them warm.
Usually sprouts withing 24 to 48 hours after that.
The only time I’ve ever had an issue with seeds not sprouting was two strains, and I believe it was the breeders fault and not of my own since others had the same issue. (Maybe the seeds were too fresh or too old..idk)

What would you consider “very warm” water to be, like almost steaming hot or? I wanna be sure before making something stupid haha. 70F doesn’t seem to be “that” warm, my room temperature is between 74-77F, that should be okay without any extra warmers?

I just put them straight into soil, water them in, and leave them alone. I normally get 100% germination. Messing with paper towels and all that is a waste of time. By the time you germinate in paper towels and then plant in what you’re growing in a seed that was planted straight into soil is already developing the roots. You can do the paper towel method but it’s not necessary.

Holy cow. Paper towel, h2o2, water temps, best methods.

The best method is straight to the medium you are using as by default the most important aspect would be colinization of root from bacteria and fungi.

Once you master this lets talk a 12-24 hour soak as the whole paper towel thing is ameture’ish imo. Im pretty certain once the seed is 100% hydrated it is at 100% max growth, soaking just speeds up hydration and past that i can see no futher benefits to keeping it in a paper towel over its new home.

Some may see different but in all ways the soak and plant is the quickest.

Mj isnt really that temp dependant so any water and any temp so long as its .either too hot or cold. For paper towels natural unbleached type, hemp if ylu think that makes you even more supercool.

I use the soak to get more precise timimgs and suggest there is no rush until you have everything down

Little things like those leaf curls and serrations pointing up or down pissed me off about flourescents and such lights in general. Did i find more light made for less of that idk but felt that way at the time

I don’t even pay attention to a little curling when seedlings are this young. They grow out of it and a week from now you won’t even know. Too many people obsess when the plants leaves are not perfect and start trying to fix something that will resolve itself. I just leave them alone and let them grow. I germinate many seeds from many different plants. All of them at times will have weird looking leaves sometimes. In the end they all grow just fine. But that’s probably because I don’t freak out and start dumping stuff on them, worrying about runoff pH, spraying with CalMag, etc.

Cannabis is an easy to grow plant. There is absolutely no need to do anything special to get it to grow. I start my seeds the same way I do with tomatoes, peppers, squash, cucumbers, flowers, etc. I put the seed in some dirt and give it a little water. Keep it in a reasonably warm location. No need for paper towels, heat mats, domes, etc. I know you know that. But too many others don’t and follow some convoluted process for starting seeds.

How to Germinate Cannabis Seeds Fast & Reliably

Like any early stage in the cultivation of marijuana, carrying out a good germination is decisive in obtaining shoots that develop rapidly and obtain powerful seedlings.

In this guide, we will discuss how to germinate your seeds so they sprout in good condition, and how to treat them when they do.

Before you start, make sure you have your growing environment ready and time available to spend. Once the growing process begins, the plant will not wait for you.

Introduction To The Cannabis Seed

If you germinate a seed the right way, it will swell until it breaks the shell. The first thing you will see sprouting is a small white dot called a radicle. This is where the root of your marijuana plant will develop, and will be responsible for absorbing water.

The radicle will grow and push the seed up. Next, the first “leaves” called cotyledons will sprout, and these will finish breaking the seed until it can fully open. At this point, you should already have the plant in a medium where it can grow.

Next, the first characteristic marijuana leaves will emerge — the cotyledons are not really leaves, and they eventually dry out and fall off — as the root begins to develop.

Congratulations! Your plant has been formed correctly.

How Do I Know if a Seed is Healthy?

It is possible to germinate marijuana seeds found in a joint you got on the street. But the best way to ensure you have healthy seeds is to buy them from banks with a good reputation and history, and choose varieties of marijuana seeds for the type of crop you desire.

In general, any seed that is dark and does not break easily is a healthy seed that will germinate well. If the seed is white or pale green, it is likely that it will not germinate.

Obviously, it is always better to do the test before deciding to discard it: If a plant is born, it was a healthy seed.

How Do I Know If It’s Female or Male?

There is no physical difference. If you don’t know where the seed came from, it will be impossible to know the gender of the plant.

You will have to wait for the plant to grow and begin its flowering stage to know if it is male or female.

To ensure that the plant will be female, you can buy feminized seeds from a bank. If you don’t want to buy online, you can get seeds from a growshop in your city, which resell seeds from these same banks. In countries where legalization is more complicated, you will need to resort to donations. You can search for phone numbers for cannabis organizations or try Facebook groups.

I also wrote a guide about types of seeds.

What Does A Seed Need To Germinate?

– Moisture is the first thing the seed needs to activate; the radicle will break the shell in search of more moisture.

– Heat (just enough), the ideal temperature is between 70ºF to 75ºF (21ºC to 24ºC), which emulate spring conditions.

– Leave it alone while you wait for the radicle to appear.

– Be careful when you touch or move it. It is very fragile and can break.

– Oxygen is necessary for the plant to be able to breathe, not to be flooded with water.

– Darkness is not totally necessary, but it is good for the radicle to not have direct light.

Overall, humidity and temperature are the most important factors for a healthy plant.

Water is essential for seeds. You must always keep the germination medium moist — without flooding. If the plant dries out after activating, it will die. On the other hand, if you drown it, the plant won’t be able to breathe properly.

The plant will germinate better if you keep it warm. You can put a “normal” bulb close to it to give it heat — but remember that the root should not receive light. Even better, put the germination medium on top of the power supply of your Play, Xbox, laptop or the like you have. I do not recommend using 3DS, PS Vita or Nintendo Switch

The plant can develop in as quickly as 12 hours, or it can take up to two or four days. If more time passes, it will not germinate. In any case, do not underestimate the speed of seed growth. Have your growing environment ready and check the seeds a few times a day — without fiddling with them.

Marijuana Germination Methods

There are several methods to germinate seeds that are very simple and work perfectly. In the following section we will examine three of the most popular:

Activate them in Water

Letting the seeds soak in water overnight is one of the most widely-used methods by marijuana growers. Simply fill a glass with lukewarm water — between 70ºF to 75ºF (21ºC and 24ºC) — and drop the seeds inside.

Let them rest quietly until they open and the radicle comes out, at which time you will take them out of the water, taking care not to touch the radicle with your fingers, and plant them.

Some seeds take longer to sprout than others, but after 24 hours they could drown. If time passes and the seed has not sprouted, I advise you to transfer it to another germination medium and leave it near a heat source.

The following video on germinating with peat tablets (which I explain in the next section) explains the process of activating seeds by submerging them in water.

Paper Towels

The most popular method, and the one I use most frequently, is to allow your seeds to sprout on kitchen paper:

  1. Put several layers of paper on a plate or a Tupper,
  2. Dampen the entire paper with a sprayer,
  3. Important! Drain the excess water in case there is too much; you do not want water to accumulate on the plate,
  4. Deposit the seeds on the paper, leaving a few centimeters of separation between them,
  5. Cover them with several other layers of paper and moisten again, and
  6. Cover them with another plate or lid and secure them so they don’t separate.

When everything is complete, place it on a warm surface. A good trick is to deposit it on a power supply like that of a laptop or a PlayStation as mentioned above. It should not be something that will be moving in the coming days.

If you can’t find a power supply, you can heat the paper up by bringing it “normal” lamps, and putting them on top of the refrigerator or anything that emits a little heat.

Now is the time to leave the seeds alone for a few days. Separate the papers only a few times a day to make sure you keep the paper damp, and to monitor when they begin to sprout.

Once the root has emerged from the seed and is beginning to open, it is time to transplant it into the growth medium.

Dehydrated Peat Pellets

If you don’t like crafts, one of the best methods is to use peat pellets or “germination pills” — they can be bought in nurseries, grow shops, etc.

Peat pellets are specific to start seeds of all kinds; they are very easy to use and will give the seeds the perfect condition to germinate.

  1. Activate the seeds by immersing them in water, which can be beneficial for using peat tablets,
  2. Once activated, the tablets are immersed in water — in a different container — to hydrate them for about five minutes so they take shape,
  3. Then make a hole in the pill and bury the seed, taking care that the root is down and the top is not buried more than 5 millimeters.

Transplanting Marijuana Sprouts To Soil Once Germinated

If you germinated on kitchen paper or a similar method, or activated the seeds in water, it is time to transplant them into a growth medium once the radicle expands. They are still very delicate, so this transplant should not be the only one, but the first.

Small pots or disposable plastic cups are a good option for growing the sprouts. I don’t recommend that you plant the seeds directly into soil or a pot because it will be more difficult to maintain the conditions you need to finish the process properly. A small medium will help you to regulate humidity and temperature.

You will need to get a good substrate, airy and loose. If you use soil from your garden, which is not the best medium, make sure that it does not form mud when it is wet and that it does not remain hard when it has dried either.

Transplanting Step by Step

  1. Fill your pots or cups with substrate.
  2. It is important to make holes in the cups for excess water to drain,
  3. Moisten the substrate without soaking it. Using a sprayer makes things easier,
  4. Make a hole in the substrate with a pencil or pen deep enough for the radicle to enter completely, but for the top to be barely buried at about 5mm,
  5. To transfer the sprout, take it gently and insert it into the hole with the radicle down,
  6. Cover the hole gently with a little soil so it can come out smoothly, and
  7. Moisten the top of the soil a little.

When planting the seed/sprout, try to use small tweezers so you don’t have to touch them with your hands. If you don’t have any, be very careful when handling it and do not touch the radicle with your fingers.

If you germinated the seeds in peat tablets, you can transplant the whole tablet into the glass or small pot. As for humidity, the same rules apply, moisten without soaking.

Make sure the substrate is always wet as time passes. The top will dry quickly, so stay alert and keep it moist, but be careful not to water it if it’s still wet.

Light: Now It’s Time!

This is when you must give them light. When the plants are outside, they open their cotyledons quickly to make way for their first leaves. Or you can put them indoors if you are growing that way.

If you are growing your plants outdoors, make sure the sun is not too strong; if the pot or glass heats up too much, the plants will burn. Put them where they receive sun indirectly, in a window, for example.

Wrapping Up

It may take a few hours or a few days, but in a short time the seedling will come out of the substrate looking for light. If after ten days it still has not left, it is likely that it will never do so.

Before moving to the final growth medium, wait until the seedlings are stable and have at least 4 leaves so that they can withstand the last transplant without too much stress.

The good thing about plastic cups is that you can cut them out, which makes it easier to transplant.

Common Germinating Mistakes You Should Avoid

Looking at them too much

Constantly uncovering the seeds to see how they’re coming along can stop the whole germinating process. You must be patient with marijuana and let nature do its work in peace.

Little Heat

If the growing environment is not warm, the seed will know that it’s not the right time to sprout. As mentioned above, the ideal temperature for the seed to grow is between 70ºF and 75ºF (21ºC and 24ºC).

Touching them with your Hands

Putting your finger in the radicle can cost you the crop. It is very fragile and easily separates from the seed. Always grab it by the part of the shell or, failing that, the cotyledons, and always do it delicately.

Too few water

I never tire of mentioning that marijuana seeds must be in a humid and moist environment 24 hours a day for it to grow. If you let the environment dry, the seed will die.

Too much water

Once the seed is open, it needs oxygen to live – if you don’t let it breathe it will die. If you use a water sprayer it will be easier for you to avoid going overboard. You should also always make sure to drain the excess.

Hard pipe water

Some cities have water that is loaded with salt or lime. In these cases, it’s better to use bottled water (and if you plan to irrigate your crop with this water you should find ways to clean it as it will also affect the growth of the plant).

Fertilized Soil

The plant does not need fertilizers or stimulants during its first weeks of life. Compost soil could burn it. So, a quality growing soil will be necessary.

Planting them too deep

The seed must be buried deep enough so that it is barely covered and can easily break through. The ideal height is about five millimeters.

Using Moisture Domes?

According to the Mandala Seeds bank, it is not recommended to prevent ventilation using domes because it can quickly cause fungi in the germination medium.

On the other hand, Sensi Seeds bank does recommend them but you should take care not to use them for a long time. It also mentions the importance of ventilation.

Thank you for reading

Any of the methods listed in this guide will achieve a germination percentage close to 100%. But remember, there will always be seeds that do not germinate; even the most prestigious banks cannot guarantee that all their seeds will sprout.

The interesting thing is that although some will be unsuccessful and others may take longer, some will open quickly and grow strong. This will tell you from the beginning which are the most vigorous plants, and they are probably the ones you will choose if you want to have mother plants to make clones or your own seeds.

Now that you know how to germinate and transplant the seedlings, the next thing to study is how to take care of your plants in their first weeks of life. Everything has to do with the growing environment you have prepared before starting to germinate, or you will not have enough time to treat your seedlings properly.

In a short time, I will write guides on preparing your growing environment — whether you are going to grow outdoors or indoors — and on the treatments for the first week of vegetative growth. If you want to be alerted when they’re published, sign up for my mailing list below.
