What Does it Mean to Germinate Cannabis Seeds?
Germination is the natural process by which a particular organism grows from a spore or seed. In this case, the term is referring to the sprouting of a cannabis seedling from a seed , which can be encouraged by help from the cannabis grower. Germinating your seed is the first crucial step in the cannabis growing process, and it can be surprisingly simple with the right tools. Even though the process of getting a seed to sprout and bear a healthy plant is a challenge for some growers, it doesn’t have to be when you start with a grow kit from a Pot for Pot. With our help, your plant will sprout and start growing in no time!
What to Understand About Germination and Endosperm
The first thing to understand is that seeds come naturally equipped with their own starting food- endosperm. It plays an essential role in ensuring your plant reaches its full potential. As a seed begins to sprout, this starchy blanket around the embryo provides nutrients to a growing plant. If it doesn’t seem like a lot, don’t be fooled- there’s enough starch there to feed humans.
That starch is only part of what you’ll need, however. You’ll also need to provide specific temperatures to germinate your seeds. Ideally, you’ll want to keep the temperature around 25 degrees Celsius (77 F) for the best results.
What Happens During Germination?
The process of germination is when plants start to sprout from their seeds, and it’s relatively the same throughout the plant kingdom. A little bit of moisture makes the tiny plant inside crack open its outer shell and sprout upwards while pushing its root downwards. Once it’s cracked through the shell, you’ll need to give your little babies a bit of water and some love for the fun to begin.
Your seeds will need the right conditions to break through their shell and continue to grow, however. Otherwise, they may take longer to germinate. Our seedling starter kit can help you create those perfect conditions. It makes sure your seed has just the right amount of water (so that it stays moist, but not too wet). Once it has germinated and grown enough to sprout its third set of leaves, simply move your young plant into the a Pot for Pot fabric pot for continued healthy growth.
It’s best to germinate seeds indoors where you can better control the temperature. Seeds are more likely to sprout in a warm and stable environment.
How to Sprout Marijuana Seeds
Marijuana plants start as a seed . That tiny thing resembling a pebble is a whole plant securely stored with a supply of food to support itself for a few days. In the germination process, the food converts into sugars, which the plant uses to cut the shell and develop its root. Identifying a healthy seed is, therefore, the first thing that you need to do.
The sprouting process is the foundation of your marijuana plant, so do not take this step lightly. Other than starting with a high-quality seed, you need to ensure that your conditions are optimal. It is challenging to optimize the natural mediums, which is why a medium such as Jiffy Pellets comes in handy.
Different Ways to Germinate
There are many ways to germinate seeds, but we recommend using peat pellets. Not only is it the safest way to start your seeds, but it’s also the easiest. Jiffy is hands down one of the best brands of peat pellets on the market , and if you are thinking about germinating using peat pellets, this is the way to go. This method is great for avoiding the risk of damaging new roots. We’ll get into more detail about the wonders of Jiffy Pellets in a later section of this article. But first, let’s explore the benefit of peat pellets in general, along with some other mediums growers can use to facilitate effective cannabis germination.
Peat pellets are comprised of decomposed vegetable matter which your plants will absolutely love. When you add water, it expands, creating a nutrient-dense medium that is a good replacement for soil. When the roots are visible, you can transport the whole pellet into a Top Soil mix with fortified a Pot for Pot Superb Soil so it can continue developing without accidentally causing root damage.
Basic Mediums for Marijuana Germination
There are many different germination methods, and results will vary. Here are some basic ways to sprout your seeds :
Sprouting marijuana seeds in regular soil is a common practice. Soil is a natural medium and can protect the seeds as they develop their fragile roots. For this option, be sure to start with the right type of soil for marijuana. Use a seed starter or fertilized potting soil with a pH of around 6- 6.5. Soil has both minerals and spores that support growing marijuana plants. Soil can have too many nutrients for fragile seeds so take care when doing this method that your soil isn’t too hot.
Water is another method for sprouting a marijuana seed. Soak seeds in a cup of water in a dark place for 24 to 48 hours. Plant after 48 hours whether or not the seed has sprouted a tail or not. The advantage of using water is that you can ensure adequate moisture for germination. The plant will also have an easier time breaking its shell compared to when it is in a soil medium. It is really important that your water is chlorine free and ideally pH neutral to slightly acid. (with a pH of 6.5- 7.0)
This mineral wool comes from volcanic rock and other materials such as limestone and basalt. To make this material, the ingredients are heated into molten lava and rapidly spun into threads. These threads then undergo compaction, curing, and finally, cutting.
While Rockwool is a suitable environment for germination, you’ll need to adjust it a bit for growing marijuana. First, you’ll need to add fertilizers- around 600 parts per million. You’ll also need to reduce the pH, which is too high to support sprouting. It’s also a bit dangerous to use, so please wear gloves and protect your mouth and eyes while handling it.

The Best Marijuana Germination Medium: What to Know About Jiffy Pellets
For the best results, you need a precise understanding of how to get started growing your marijuana plant. As stated a few sections above in this article, choosing Jiffy Pellets as your initial medium is probably the best way to go. Every a Pot for Pot kit includes a Jiffy Pellet, so you don’t need to worry about purchasing it separately, and if you run out, you can order some refills or one of our expansion kits .
What is a Jiffy Pellet and How Does it Work?
A Jiffy Pellet is a natural, biodegradable growing medium conveniently available as little compact discs that help sprout seeds into seedlings. Jiffy Pellet composition includes peat moss, a mesh, and other ingredients such as lime, fertilizer, and ammonium to help seedlings grow.
Jiffy Pellets are both a container and a potting mix for sprouting seeds. Peat moss is a medium that’s rich in organic materials, and the mesh securely holds the peat moss in place. Using Jiffy peat pellets either indoors or outdoors is an effective method to grow healthy and robust marijuana plants.
To use a Jiffy pellet, water it first. Then, place your marijuana seed a bit below the surface level. When the plant is strong enough, transplant the entire pellet to a larger pot.
What are Jiffy Pellets Composed of?
To help you better understand the advantages that Jiffy Pellets can provide to your seed germination efforts, let’s take a moment to explore the various beneficial components they contain and how they work to benefit your plants.
Technically, a Jiffy peat pellet is a small disc made of compressed material. However, Jiffy pellets enlarge up to seven times their original size when you add water , creating a suitable environment for the sprouting process. The fine netting keeps the Jiffy pellet ingredients in one place as your seed sprouts. Said ingredients include:
Peat is an organic medium that provides plenty of nutrients for sprouting seeds. It is made from sphagnum peat moss, which has a high water-holding capacity as a result of its fluffy and light texture. Peat provides excellent root aeration, making it easy for roots to grow without interference.
Lime, Ammonium, and Fertilizer
Jiffy pellets are primarily made from peat moss. However, peat moss on its own is not ideal for sprouting seeds. That’s why they also include lime, which raises the pH of the medium. Jiffy Pellets have a pH of 5.5, compared to peat moss’s 4.4.
Jiffy Pellets also include fertilizer that provides seedlings with all their required nutrients for the first 1-2 weeks. You won’t need to add anything else as your seed sprouts. After transplanting, you can apply fertilizer, if desired.
How Big are Jiffy Pellets?
Jiffy pellets come in diameters of 24 mm, 33 mm, 41 mm, and 70 mm. The sizes vary to cater to the various needs of different seedlings. The larger Jiffy Pellet sizes are convenient to handle and are ideal for marijuana.
How to Germinate With Jiffy
Jiffy pellet instructions are easy to follow and will take you less than 20 minutes to set up, ensuring you’ll be able to start your cannabis seed germination project quickly and easily without wasted time or effort.
Choose Your Container
The first step is to place your pellets in a container. Ideally, you can use a Jiffy pellet tray. Ensure they do not overlap and leave a small border for water retention.
Water Your Jiffy Pellets
You can use tap water or distilled water. Keep in mind, tap water may have chlorine, which is harmful to your plant and can cause it to dry out faster. However, you don’t have to buy distilled water to prevent chlorine problems. Evaporate the chlorine by pouring your water, and let it rest for some time. Use very warm water, around 95oF, to help the pellet expand faster.
Plant Your Weed Seeds in the Jiffy Pellets
Place the seed in the middle of the enlarged pellet. Don’t place the seed too deep, or it will not sprout.
Cover Your Seeds
To avoid moisture loss, use a plastic cover – this usually comes with the pellets. You can also use plastic wrap. If you don’t have a Jiffy pellet dome, you will need to water again after around seven days. Avoid dropping water from the top; otherwise, you will disturb the developing seeds.
Transplant Your Plant into Some Soil
The seeds are usually ready for transplanting after two weeks. To do this, simply make a hole in the soil and place your pellet directly in that spot.
An Alternative to Jiffy Pellets to Consider
Coir is a popular alternative to Jiffy pellets , with Coconut Coir leading the trend. This material is made from coconut husks. If you choose this medium, use a coir Jiffy Pellet tray to hold it. Coir has water retention capacities similar to peat, but not as good, and it is more airy which means you will want to water it more often and make sure it is compact.
Coir also repels insects and is reusable , so it can help you if you choose to expand your growing operations to include more cannabis plants.
What to do After Germination
After your seeds have germinated, they need to go into a pellet so the roots can spread out and grow. You may be wondering just how far in the jiffy pellet the seeds should be planted once it has germinated. You’ll want to drop the seed about a half-inch to an inch. If the seed has not sprouted, it’s okay to place it in the jiffy pellet – as long as it has soaked for at least 12 hours, but no more than 24 hours. If it has sprouted, drop the white root downward, so that the head of the seed is about an inch below the surface.
Damping-Off With Hydrogen Peroxide
Once your seed becomes a tiny plant, it’s now known as a seedling. This is great, except that seedlings are very delicate. You’ll want to be on the lookout for the number one seedling killer: damping off. Damping-off occurs when something (such as fungi or other diseases) causes the nutrients in your plant to stop being transported properly. The stem becomes mushy and falls over, and your plants will die young. The risk increases when there is minimal direct sunlight and air circulation, combined with warm temperatures and high humidity.
Eventually, your plant will be able to protect itself, but until then hydrogen peroxide is an excellent solution to this problem before it can begin. Hydrogen peroxide provides oxygen to the soil and reduces the chances of fungus spores developing.
To effectively prevent damping off, combine 1 tsp. of hydrogen peroxide with 2 cups of water. Use this solution to water the plants. Or you can soak the seed in 1% hydrogen peroxide before planting.

Germinating Cannabis Marijuana Seeds
Much controversy surrounds the raising of cannabis seed. Many first time growers are bombarded with advice, often conflicting, on how exactly this should be done; however, it need not be such a complicated task. Cannabis seed is simple to grow, and if fresh, 90-100% germination rates are not unusual.
The ‘Kiwiland Method’ for raising seed, has been developed from professional horticultural practices used the world over. We use it because it works, and it’s simple.
Table of contents
The list below is standard equipment recommended by Kiwiseeds and assumes you already have the necessary grow space and lighting set up. If you haven’t already got your equipment you can buy that online at https://www.kiwiland.com/
1. Propagator with bottom heat or
2. Heat pad + seed-tray
3. Thermostat controller
4. Soil thermometer
6. Large jiffy pots + seed-raising mix or
7. Rockwool starter blocks
8. Fine sprayer
9. Identification labels
Wet thoroughly enough perlite to cover the bottom
of the propagator approximately 2cm deep. Plug the propagator, or heat pad, into the thermostat controller, plug the controller into the power and set for 23 C. Place the heat-sensing probe into the wet perlite just beneath where the seedlings roots will be. If using a heating pad lay it out beneath the propagator tray.
Jiffy pots preparation
Pre-soak the jiffy pots in warm water then fill them to the top with seed-raising mix making sure to take out any bigger pieces that may obstruct the young shoot as it emerges.
(This can also be done with the help of a coarse sieve if you like.)
Completely saturate the jiffy-pots and their contents, but allow them to drain well. Do this carefully so as not to wash the fine soil away. Top them up and repeat if the mix has sunken too much. It’s important to have them as full as possible to give the young roots plenty of room to grow for the week or two until they are potted on, and, because having a greater volume of the mix in the pots means they take longer to dry out under the warm lamp.
With a thin pointed object such as a pencil, make a small hole in the center of each jiffy-pot about twice the depth that the seed is long (This varies with strain, but 5-8mm deep should be sufficient. Often the mistake is made of planting seeds too deeply, and they rot before they see the light of day. To ensure this doesn’t happen, never sow seeds deeper than 1cm). If sowing more than one variety remember to prepare identification labels in advance and label them as you go to prevent mix-ups.
Put the cannabis seeds in Jiffy pots
Sow seeds directly into the holes, and cover with a little of the moist seed-raising mix from around it with the help of the pencil. Use a little more fine mix if needed. Some growers have the patience to sow seeds a certain way up, and this can be beneficial, especially with big seeds. If this is done place the seed, point up, ensuring the root can travel downwards with ease.
Watering the seeds
Using the mister bottle, spray the freshly covered seeds until the mix is damp. Don’t pour water onto the pots as this can wash away the mix and expose seeds.
Transfer jiffy-pots into pre-warmed propagator tray, and settle them in making sure the wet perlite surrounds the pots, getting right up between them. This ensures the pots stay moist until well after the seeds germinate, protecting the young roots from drying out.
Lighting, temperature & humidity
Set the tray under either fluorescent lighting or a low-wattage H.P.S. to keep the newly planted seeds warm. At this stage no light is necessary but warmth is important, and low light provides this without drying the pots out. An air temp of 20-22C is ideal, a degree or two lower than the soil temp (around 23C). Humidity if regulated can be set for around 60%.
Growing the cannabis seedlings
As soon as the seedlings have germinated they need light. The food store supplied by the seed itself has all but been used up, and the plant needs light to photosynthesize and grow.
When growing marijuana in the vegetative stage you may choose how long you wish to keep the lights on, as long as it’s 18 hours or more. The advantages are that plants will grow faster with 24 hours light, and a constant temperature is easier to maintain this way, something hugely beneficial to young seedlings. Disadvantages are that you’ll need to water more, of course, your lamps and ballasts don’t get a break, and the electricity bill increases.
Some people advise keeping young seedlings under fluorescent lighting for a while but this doesn’t provide them with the correct spectrum for photosynthesis. It is best in our opinion to place seedlings directly under low wattage H.P.S lamps, 150/250/ or 400 watts, at a good distance away.
Once the plants are a few days growing they need to be moved closer to the lamps in order to prevent stretching. Move them as close to the lamp as the tops of many plants would be comfortable. (30-60cm depending on the lamp size.)
Make sure a breeze (oscillating fan) is blowing over the young plants, primarily so they don’t overheat, but furthermore to help strengthen delicate stems by stimulating cellulose production. Spindly stems cannot support heavy flowering growth. The importance of your internal air circulation cannot be stressed enough. It will exercise your plants and make them grow stronger while reducing many hazards that could ruin your crop.
Now that the plants have strong light they require more water and nutrients as well. A light organic feed or nutrient solution starting with an E.C of no more than .8 (with the water already at .5) can be sprayed directly on the plant and watered into the soil. The seed-raising mix contains no nutrients so within a few days the plants will be hungry.
Young seedlings love humidity, and a constant 60-70% is ideal at this stage. Use a cheap mister bottle, and spray regularly freshwater (ph- 6.5-7.5) over the leaves. This increases humidity, and washes dirt and dust off the leaf surface, unclogging stomata and enabling the plant to breathe properly. In natural conditions, the rain would do this for us.
Problems raising seedlings
Problems can occur during germination. Here is a list of some of the more common reasons why your seeds may not be doing so well.
Seeds need to be damp, not wet for germination. Excess water prevents oxygen from getting to the seed. Poorly drained soils may also cause soil fungus diseases. The condition of wet soils may be improved by adding perlite, which will aerate your soil. Make sure any trays or pots you use have holes in the bottom to let the excess water drain.
A certain amount of water is essential for germination, so maintaining constant soil moisture during the germination period is vital. Spray the soil surface with a fine mist, or cover containers with glass or a damp cloth to prevent your soil drying out. Make sure you remove the cloth once the shoot emerges.
High temperatures result in excessive soil desiccation and injury to seeds and seedlings. We recommend a constant temp of 20-25 degrees.
Cold temperatures can kill seedlings and prevent germination. Cool temperatures can result in slow, uneven germination, and attack by soil diseases. If growing outside, you may want to start your seeds indoors, before outdoor planting. Make sure planting is not done too early when there is still a chance of frost.
If you sow your seeds too shallowly the seeds can dry out. A depth of between .5 to 1cm is about right.
Soil too firm
Making your soil mix too firm can prevent oxygen from getting to your seeds and drainage can be affected. Pat freshly covered seeds lightly with your fingers.
Soil too loose
Soil that’s too loose results in too much air surrounding the seed. Seeds planted in this manner will not absorb moisture properly, and it’s likely they’ll dry out. Cover freshly sown seeds with fine mix and pat down lightly with your fingers.
Seeds may rot, or the young seedlings may fall over. Overwatering, poor drainage and lack of aeration will increase the likelihood of this occurring. Plant seeds in sterilized potting mix, and make sure your containers are clean.
If your seeds have not been stored correctly they can deteriorate. Look for darker seeds that are a little bigger, without cracks or chips. Any seeds that look shriveled or wrinkled should be discarded, as this means the seed has dehydrated and is dead.
How to germinate cannabis seeds in peat pellets
Not all germination methods are equally successful. Some will disappoint you, while some can surprise you in quite a positive way. One of those methods that tends to provide awesome results and is quite simple and easy to achieve is germinating cannabis seeds in peat pellets.
Before we head onto the actual process of germinating marijuana seeds in peat pellets, let’s check out what the benefits of using jiffy peat pellets are and why you should choose this method of germination.
What are the Benefits of Peat Pellets?
If you’re not yet sure whether this method is suitable for you, check out some of the main benefits of using peat pellets to germinate your seeds below!
- They are easy to work with.
Peat pellets are super easy to work with. They are lightweight and highly compressed and they transport quite well. They can be planted into small and large containers or directly into the ground.
- They are the full package.
Peat pellets are a container and a medium all in one. They meet all the requirements your seeds need to grow with a consistent quality. They require less labor, less water and provide faster and better germination.
- They are eco-friendly.
Using peat pellets means growing in a medium that’s safe for the environment since its biodegradable, unlike other popular choices like rockwool.
Step-by-Step Guide to Germinating Marijuana Seeds in Peat Pellets
Now that you’re familiar with the benefits of using peat pellets to germinate your cannabis seeds, let’s go over the entire process step-by-step so you can consistently record higher and faster levels of germination and get a more consistent quality and results.
Jiffy pellets have easy to follow instructions, particularly suitable for novice growers. Here are the main steps you need to follow when germinating marijuana seeds in peat pellets:
Step 1: Get your container and your pellets ready
While you can use any type of container, ideally you should get a pellet tray that acts as a pellet holder and can typically contain up to 25 pellets per tray.
Make sure your pellets don’t overlap and have small borders between each so they can extend as they soak up the water.
Step 2: Cover with water
Pour water onto the tray to expand the pellets. Use warm water (up to 95°F/35°C) to help them expand faster. While you can use both tap or distilled water, we recommend using distilled or purified water so as not to expose the seeds to harmful substances which can be found in tap water, such as certain minerals. Keep on pouring water as they soak it in, allowing them to rise up and fully extend. Repeat the process as long as it takes until your pellets have fully risen and are ready for planting. Once they do, remove all of the excess water from the tray and head onto the next step.
Step 3: Place your seeds
Once the pellets have fully expanded, take your seeds and place one in each pellet. Place them in the middle at about 3/8 of an inch (1cm) or so. Don’t put them in too deep as this will prevent them from sprouting.
Once you plant the seeds, cover them with the excess peat from the sides and cover the tray with a lid or a plastic wrap. If you decide to purchase the specialized peat pellet tray, you’ll see that it comes with a humidity lead that goes on top, so use that one to cover your tray.
Step 4: Continue watering
You will need to water the pellets in around a week after planting your seeds. Just make sure not to water them from the top down as this can disturb the germination process. Keep your tray by a window or a warm, sunny spot and just wait for the seeds to sprout in a few days.
Step 5: Transplant
After about two weeks your seeds should be ready for planting. Then, you can plant each pellet directly in the soil or in a pot, depending on your preference.
As you can see, germinating weed seeds in peat pellets is an easy process that doesn’t require a lot of work. However, if you still have some unanswered questions on the subject, we hope this list of some of the most commonly asked questions on the subject can help answer some of your dilemmas.
Is there a certain way to plant cannabis seeds in peat pellets?
Yes, there is. To make sure you get the best results, you’ll want to place your seeds about 3/8th of an inch (1cm) deep, as if you plant them deeper within the pellet, they may not sprout.
Can I germinate autoflower seeds in peat pellets?
Absolutely! Germinating autoflower seeds in peat pellets is a simple and easy process and it follows the same steps as germinating any other marijuana seeds.
How many days does it take to germinate a cannabis seed?
Once planted, the seeds should start to sprout within two days, but it may take up to a week. Once they’ve sprouted you can remove them from the tray and plant them in soil at any point after they’ve sprouted, although we recommend waiting for a week or two to make sure they are ready for planting.
What if I don’t have access to peat pellets?
While this is quite an effective and sustainable way of germinating seeds, there are a few other ways you can use to achieve the same results. Germinating marijuana seeds in water is also a perfectly viable and safe option and can provide excellent results, which is great when you don’t have pellets at your disposal and are looking for an alternative solution.
