How Long Does It Take for Marijuana Seeds to Sprout?

Growing your own weed takes time and energy, but when you obtain your first harvest, you’ll know how rewarding it is. Growing weed isn’t hard science, especially if you have previous experience with growing plants, so if you learn the basics the rest will quickly follow.

This article focuses on the germination process of growing weed, and the most common germination methods, as well as some tips for success. Whether you’ve chosen indica or sativa, or regular or autoflowering seeds, germination is crucial to the plant’s growth process and the start of its lifecycle, so keep on reading for some helpful tips and information.

How Do Weed Seeds Work?

Weed seeds are the small oval-shaped fruits of the cannabis plant. They’re covered in a subtle membrane, albumen, which keeps the center of the seed healthy until it’s time for germination. At the center of the seed you can find the embryo from which the new plant grows from. This embryo contains the plant’s genetic code and is the place from where the taproot starts forming.

Similar to other plant seeds, cannabis seeds are the fruit of the pollinated flowers of female weed plants that don’t contain any psychoactive effects. However, they can be consumed as food since they’re the source of a lot of vitamins, minerals, and beneficial proteins.

Pros and Cons of Using Cannabis Seeds

When it comes to cannabis cultivation, germinating cannabis seeds is one of the methods you can choose. This method of cultivation has a lot of benefits, but also a few downsides.

Some of the benefits of cultivating marijuana seeds include:

  • The presence of the taproot from the germinating seeds provides more support in the initial growth stages of the cannabis plant.
  • You don’t inherit pests from the mother plant.
  • As a result of the expansion of the cannabis market, you can choose from a huge variety of high-quality seeds from a lot of seed banks all over the world.
  • Seeds can be stored for a long time without going bad and still germinate.

On the other hand, the downsides when using cannabis seeds include:

  • Having to wait until the plant reaches the flowering stage in order to differentiate whether it’s a male or a female plant.
  • Seeds can take a while before they pop (germinate).
  • Germinating seeds is harder for newbie growers since it requires more skill.

Cannabis Seeds vs. Clones

Compared to cannabis seeds, cannabis clones are an example of asexual propagation, or replicating from a single parent. The cutting is taken from a stable mother plant and is grown into a genetically stable ang genetically identical plant under the right conditions. The benefits of using clones for weed cultivation include:

  • Ensuring that the gender of the new plant is female.
  • Knowing which traits your plant will have.
  • The cultivation process is several weeks faster compared to a seed that needs to sprout.
  • The clone is less delicate than the seed is at the beginning.
  • Growing clones is easier since you only need to “plug and play”, so beginners will find this process easier.

How Are Marijuana Seeds Grown?

You can grow marijuana seeds both inside and outside, depending on the conditions, space, and resources available. Generally, growing marijuana indoors requires a dedicated space and equipment, like fans, grow lights, and heating pads. This method is more private and gives you better control, but at the same time, it’s more expensive and demanding. Growing outdoors is the easiest and cheapest way to grow, provided that there’s enough sunlight – at least 6 hours of light daily. The downside is that you’ll be limited to the growing season even though outdoor marijuana yields a lot more weed because the plants grow bigger. If growing outdoors isn’t an option for you, or you want to grow all year long, you can always invest in some quality lights.

Marijuana plants usually start out as a seed, but some growers use clones as well. Basically, a clone is a cut-off from a plant that’s used to grow another plant. Growing weed from seeds is a little more convenient, especially if it’s your first time growing weed, plus, seeds give a stronger plant.

Before the seeds turn into a beautiful marijuana plant, they need to be prepped for transplanting, or in other words, they need to germinate.

What Is Seed Germination?

Seed germination is the process when a plant starts sprouting from seed and continues growing from there. During the germination process, the food reserves present within the seed are converted into sugars that the plant uses to increase in size, causing its root to start breaking through the shell. This is the first sign that they have germinated.

Once emerged, the root is crucial to the plant’s survival as it provides the necessary nutrients from the environment. After this process, the germinated seeds are ready to be planted in the growing medium of your choice.

The simplest and most common one is soil, but in recent years, hydroponics are also becoming popular – Rockwool cubes and coco, especially. The downside of these growing mediums is that you need to be well-versed in pH levels and maintain the optimal pH and nutritional status of your plant at all times.

Germinating Your Cannabis Seeds

There are three most common germination methods.

Soaking Cannabis Seeds in a Glass of Water

This is the simplest method and it’s especially helpful for older seeds as it helps to wake them up, or even seeds with hard shells. The process is pretty straightforward: you need to fill the glass with lukewarm water and soak the seeds. At first, they should float in the water, and sink to the bottom after a few hours have passed. If some of the seeds don’t sink, you can try pushing them gently to the bottom.

After you’ve soaked the seeds, put the cup of water in a dark and warm place, and leave them for 36 hours at most. The seeds that have started sprouting will have a tiny white root sticking out. If, after 36 hours some seeds have no signs of sprouting, we recommend you put them in a warm and moist place to encourage the germination process.

The Paper Towel Method

This method is probably the most popular one among weed growers. You’ll need a kitchen paper towel and two plates. We recommend you use a nonporous paper towel (usually the cheaper brands), as this will retain moisture for longer. Here’s a brief step-by-step guide:

  1. Moisten two sheets of paper towel and put them on one of the plates;
  2. Carefully place the cannabis seeds over the wet paper towels;
  3. Fold the damp paper towels over so that the seeds are well covered;
  4. Cover with the other plate to create a dark space, but make sure to leave some room for oxygen, i.e. don’t align the plates perfectly;
  5. Check on the seeds often, about every 5-8 hours, and if you notice that the paper towels have dried even a little, spray them immediately to maintain the moisture.

If all goes well, the seeds should take 24 hours to start sprouting, but if they haven’t (this might happen with old seeds), leave them for up to 72 hours and check on them constantly so they don’t run out of moisture. With this method, you’ll need to be patient, as some seeds just need a little more time.

Germinating Seeds in Potting Soil

You can also mimic nature’s way by germinating marijuana seeds directly in a growing medium. This method allows the seeds to sprout in potting soil and continue living there without the need for transplanting. The upside of this method is that the marijuana seedlings will get used to its home environment from the beginning and it’ll be easier to thrive.

To do this, you need to put the seed about ½ inch deep in moist (not wet) soil. Put some soil over the hole to cover it and press lightly. The seed will germinate under the surface and, in about 4 to 10 days, it should slowly spring to the surface.

So, How Long Until They Germinate?

As you can see, the germination of cannabis seeds depends entirely on the type of seed and the chosen method. A rule of thumb is that it takes approximately 24-48 hours for the seeds to start sprouting, however, there can be some exceptions to this rule, of course. Just remember that moisture and warmth are very important and remember to check on the seeds often.

What Do Marijuana Seeds Need for the Germination Process?

Seeds need the ideal environment to break through and start germinating. Seeing as this process is one of the most important steps in growing your marijuana plants, here’s what you need for achieving the best germination rates:

  • High moisture levels – your cannabis seeds need a lot of moisture (about 80%) to help them expand, however, be careful not to add too much water, and always make sure you use clean tap water;
  • Warm temperatures – the marijuana plant is a warm-season plant that thrives in springtime, so ideally, you should put the cannabis seeds in a warm place and maintain the temperature between 68°-72° Fahrenheit or 20°-22° Celsius;
  • Minimal interference – you’ll need to avoid touching the germinating seeds while they’re going through the process because the taproots (cotyledons) are very fragile and prone to breaking. If you must handle them, wash your hands first, or use clean gloves.

Remember that when the seeds are healthy, they will respond well to this basic setup and you won’t need to do or add anything extra to help your cannabis plants grow.

A Few Don’ts for Successful Marijuana Seed Germination

Even though seed germination is a relatively straightforward process, knowing a thing or two beforehand can help you avoid making mistakes and make the most of your seeds.

  1. Don’t let the germination container dry out. Moisture is very important to kickstart the process, but maintaining the moisture is even more important. Whichever method you choose to germinate the seeds, we recommend you check up on them daily to ensure that there is enough moisture. This especially applies when you use a heat source to achieve warmth as it may cause the water to evaporate faster than normal.
  2. Don’t leave the seeds to germinate for too long. This means that you shouldn’t wait for the taproots to grow very large, as they will be very delicate and make the subsequent transplant more difficult for you. Plus, leaving them for too long means that they’ll be exposed to air which puts them in danger of oxidation and further damage. Therefore, make sure they’re about ½ -1 inch long at most.
  3. Don’t plant the seeds too shallow or deep. This is a common mistake that weed growers make, but it’s easy to be avoided. When you plant the seeds too deep, the seedling won’t get enough air and it may suffocate deep beneath the surface. On the other hand, if you sow the seeds too close to the surface, it will result in weak and underdeveloped stems. Your best bet is to plant the seeds at about ½ inch depth.
  4. Don’t germinate seeds in the same container. Cannabis seeds need plenty of room to grow, so if you plant several in the same pot, they will compete for light, nutrients, and space, resulting in little branching and weaker roots. This will, in turn, affect the quality of your plant. So, unless the container is big enough, you should give the seeds enough room to thrive.

So, How Long Does It Take for Marijuana Seeds to Sprout?

Seed germination is an essential step in the process of growing your own weed. The average time for marijuana seeds to germinate mostly depends on the type of seeds and the germination method. However, the usual time frame is between 24-48 hours. The most important elements that support seed germination together are warmth, moisture, and peace. Finally, having patience and being diligent will help you achieve the best results.

Soil Germination Method in 8 steps

Amongst the best ways to germinate cannabis seeds, this soil germination method is a low risk, easy method that explains how to germinate your seeds in soil. Germination can take 3-10 days, depending on environmental conditions and variety

Never use soil from your backyard! It can contain pests and moulds that will damage or destroy your seeds, seedlings or plants.

How to germinate seeds in soil

Read here which 8 steps you have to take for this soil germination method.

Step 1: Prepare your soil

Prepare your pots with clean fresh soil. It is often easy to use small pots for this, and transport them to a larger container later.

Step 2: Watering the soil

Make sure your soil is wet, but do not soak it. It needs to be damp but not soaked, otherwise you risk your seeds to rot. In most countries, normal tap water is clean enough to use. Do not add any additives to the water.

Step 3: Placing the seed inside the soil

Make a small dimple in the soil and place the seed 3-5mm deep inside the soil. Don’t bury your seed too deep! When you put your seed too deep inside the soil, it will struggle to reach the surface, and have a high risk of dying before it does.

Step 4: Cover the seed and press gently

Cover the seed with soil and press the soil gently.

Step 5: Cover the pots with kitchen foil

Cover your pot(s) with kitchen foil or microwave foil (with the small holes). The foil will act like a small greenhouse, keeping the inside of your pot warm and moist. Perfect for germination.

Step 6: Poke some holes

When you use normal kitchen foil, poke some holes through the foil. This will avoid the risk of overheating and let air flow true.

Place your setup in a room with stable temperature. 20-25 degrees is ideal. We often advice your living room

Step 7: Wait for germination

All you have to do now is wait. In our experience it often takes about 4-5 days for your seedlings to show. But to calculate for differences in conditions and seeds, we say 3-10 days is a safe estimate. As soon as your seedling has sprouted (first leaves reach the surface) you can remove the foil.

Step 8: Take care of your seedlings

All 5 seeds germinated in 4 days within 24 hours of each other. You can now place them under a grow light, behind your window or outside (during spring / summer of course).

WARNING! Do not place this germination setup outside in direct sunlight, especially during summer. Day and night temperatures vary too much and sunlight will cause the temperature inside your soil to rise to a point where your seed will be damaged or killed by the heat.

buongiorno dutch passion ho seguito il vostro tutorial e dopo 4 giorni la germinazione è avvenuta.una domanda vorrei fare,devo aspettare che si aprono i cotiledoni prima di rimuovere la pellicola o posso mettere il vas gia al sole anche se non sono aperti i cotiledoni. grazie e buona domenica

tutto ok germinazione perfeta.

When a seedling is in its first days its best to not place it in direct sunlight. This can be too much for a little seedling. When the seedling starts growing a little bit you can place it in direct sunlight

ok perfect I do this because I saw that it is the best method.I had put it in direct sunlight and it was dying, I managed to save it in time.I have one in germination and I will apply your advice.thank you very much Joe

Once the stem has come through the soil how long till you put it on a larger pot and up the tempreture

It depends a little bit on the pot size you started with.
Additionally, if you grow an autoflower its best to germinate them in the pot they will also flower in. They don’t like to be transplanted a lot.
If you grow feminised seeds than you can put them in a larger pot after 3/4 weeks.

Greetings,
Joe

Sweet thank you ,

Hi, Joe answering?? I did an error putting seeds in soil not enough wet and under lamp … I choose Orange punch feminized and autoflowering…Is a good choice for me ad a beginner or could you give me best options? (Medium-high THC and quantity of final result) I also need some good ideas about the soil to use and the power of led lamps (I’ve buyed 2x100watt multiple ranges led lamp for plant grown for about 60cm x 40cm for 4/6 seeds). I have to do another order and I’m trying to do all well. Waiting hopefully for your answer, my best regards, thanks. Heathcliff

Critical Orange Punch is a good strain to start your growing career. Please try to follow the germination steps from this blog and you should be fine Don’t start your light if the seeds have not germinated yet. For your soil I advice you to have a type of soil that has minimum nutrients because seedlings cannot handle too much nutrients, these should be added later :).
