Like almost everything else about growing excellent Cannabis, germinating your seeds successfully is pretty simple. We’ve used this very basic, inexpensive method for many years and have shared it among thousands of growers worldwide who have all had excellent results with no issues.
First make a mix in the ratio of 1/3 3% hydrogen peroxide to 2/3 distilled water.
It’s important to use only distilled water – some of the common chemicals in tap water can stunt, warp or kill your plant even well past seedling stage when you’ve already spent weeks tending it.
Then soak your seeds in the distilled water/hydrogen peroxide mixture overnight. If you’re growing multiple varieties, be sure to soak them separately. (Don’t laugh. It’s happened.)
Next, pour some of the soak water onto really absorbent paper towels, then wring or squeeze them out lightly and lay them flat. We use 2-3 towels layered together to make a nice thick absorbent nest.
The best seeds often sink and compromised seeds sometimes float, but there are always exceptions to the rule.
Then sprinkle the soaked seeds, using a clean spoon or gloved fingers, onto the moist paper towels, not crowding the seeds.
Then fold the moistened towels over the seeds to make a flat little package.
If you’re sprouting more than 12 seeds at a time, make more than one package – don’t crowd them.
Then put the moist towel and seeds flat inside a closed, unzipped storage-size plastic baggie, laying it flat somewhere away from direct light at room temperature.
In two or three days the seeds will sprout – maybe not all at once, but that’s not a problem because within 24 hours of the first seed sprouting all the others will have sprouted too. Keep your inspection peeks short as not to dehydrate the paper towel.
When the seeds each have a 3/4” root and the halves of the shell are beginning to open noticeably, meaning the embryo leaves are swelling inside, they’re ready.
You then want to move each sprouted seed into a Jiffy Cube you’ve prepared by making a small hole using a pencil or chopstick. Again – be sure you used distilled water to hydrate your Jiffy Cubes and of course use it everywhere else during germination.
Replanted into Jiffys:
Using your fingers, pick up the seed very gently by its shell, and avoid touching the sprouting root as you transfer it into the jiffy cube.
Also remember what’s unfolding inside that little shell as you handle it, be super delicate and stay conscious of the life emerging inside.
Now place the sprouting seed root-down in the hole letting it settle in naturally with the top of the seed even with the top of the hole – never push it down.
If it doesn’t nest right in, lift it out and poke the hole a little deeper. The cells at the tip of that little root hold the most miraculous ecosystem of emerging life one can imagine and while they are incredibly tough in nature they are also vulnerable to our mis-handling.
Now all you have to do is let the new sprouts do their thing they do so well, with a little help from their friends. With a day or so they will raise up their first leaves. Keep them lightly misted if you’re in a dry environment but don’t over-do it.
In a couple of days when they’ve developed their first set of true leaves, not the embryo leaves, it’s time to put them into larger pots with living soil and a mild fertilizer and then let the plants fully establish themselves.

Is using distilled water really important for germination?
Using distilled water is probably the most important part of the germination process because well water, tap water, bottled water and even rainwater contain traces of contaminants that can inhibit germination and later vegetative growth and flowering.
High chlorine in tap water, herbicides in well water, phthalates in bottled water, as well as many other kinds of common water contaminants can kill or damage germinating seeds and will definitely affect your plant’s health, yield and flower quality.
Can I remove these contaminants with a garden hose filter?
Yes most of them you can. There are a variety of relatively inexpensive filters that screw onto the end of the garden hose that you use to fill containers and water your plants. Some have replaceable screens, while others use granular activated charcoal.
There are also screw-on systems with carbon block filters that run $20-$30 and are very effective at reducing chlorine and chloramine, and at removing pesticides, heavy metals, and herbicides.

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.
