How To Germinate Marijuana Seeds With Jiffy Pellets

My favorite way to germinate marijuana seeds is with jiffy pellets. I currently have a 100% germination rate using jiffy pellets!

Using jiffy pellets is a very safe and easy way to germinate your marijuana seeds. There are only a few steps, which I will go over here in detail.

You can find jiffy pellets and almost every garden store, or you can order them here. (Of course I always order them online because I am a lazy stoner.)

They come dry and compressed. We will need to add water to them so they expand and become usable for planting.

You should NOT soak the jiffy pellets. They will become too wet and if you squeeze them out they can become unstable.

Instead, we need to slowly pour 1 cup of water over them. Then wait several minutes until they expand.

Once the jiffy pellets have expanded, we can plant our marijuana seeds.

It is very important to only put one marijuana seed per jiffy pellet.

Take one of your seeds and put it about .5″ deep in the pellet. It does not matter which way the seed is turned. Cover it with some of the top soil.

If you have a jiffy pellet kit with a dome, place that over the top. Marijuana seeds need a relatively humid environment to germinate, and the dome will help with that. Just make sure to take it off a few times per day so the seeds can get fresh air.

It will take the seeds a few days to germinate. It is very important to make sure that they jiffy pellets do not dry out during this time.

The ideal temperature marijuana seed germination is 70°-78°, so try to keep the jiffy pellets in an environment that can accommodate that.

Anywhere from 2-8 days later, you will see your marijuana seeds begin to pop their heads out of the jiffy pellets. This will not happen to all your seeds at one time, so be patient and do not mess with the ones that need a little extra time.

Once the seeds have broken through the soil, they will need to be placed on either a 24/0 or 16/8 light schedule to start the germination phase.

Good luck with germinating your marijuana seeds with jiffy pellets! If you have any questions, please feel free to ask in the comments below.

Jiffy in cannabis crops, all the information

One of the most popular products in Grow shops is jiffy, due to its low price, versatility and ease of use. But not everybody knows about the existence of these small objects, or many people do not know how to use them. For this reason we thought it would be appropriate to create this post, explaining what it is, how to use it and the advantages and disadvantages compared to other methods.

What is a jiffy ?

They are so called because they were commercialized by a company known as Jiffy Group and they are peat or coconut fiber that comes pressed and wrapped in a thin mesh. They have the shape of a small, cylindrical and flat disc which, when wet, swells up to multiply its size upwards, and contains a small hole at the top to introduce the seed or the stem of the cutting.

Its creator was an enthusiast of home-grown cabbages and other vegetables, but he did not like the way they sold the cuttings because of the lack of protection of the roots. It was for this reason that he began to develop individual seedlings that were easy to transplant, and thus the first Jiffy were born.

Jiffy Pellet Sizes

They are available in different dimensions: 24 mm. (0.94 inches), 33 mm. (1.3 inches ), 41 mm. (1.6 inches) and 70 mm. (2.75 inches). Although the most used are the 41 mm. (1.6 inches) ones. They usually come in boxes of 2000 units, but luckily stores can sell you the exact number you need and at a very good price.

Are these peat or coconut discs organic and biodegradable ?

They are totally organic and biodegradable, it is the same peat used in commercial substrates, natural. Just as with the coconut fibre, this type of jiffy was released more recently for those who love growing on this substrate, but it is made up of the same fibres that are used in coconut bricks. Even the small mesh it uses is biodegradable in a very short time, so it can be considered that jiffy will leave no trace on the planet after its use.

What are the advantages of using it ?

  • More economical than any pot
  • You can germinate many seeds in very little space
  • Makes transplantation much easier
  • Keeps humidity for a long time

How to use Jiffy pellets for germination or cutting

  1. First prepare a bucket with the nutrient solution, in this case clean water and root stimulator, with the pH lowered to 6.0 and a little bit of micro life
  2. Insert the jiffy pellets so that they are immersed in the nutrient solution
  3. Wait for them to hydrate and swell, usually no longer than 10 minutes
  4. Take the jiffy pellets out of the bucket one by one and and drain it a bit to let go the excess of liquid
  5. Place them in an upright position on a tray, with the hole facing upwards, and insert a stick or similar through the hole to make it easier for the seed or stem of the clone to enter
  6. Carefully insert the seed 0.4 inches (1 centimetre), or the stem of the cutting until at least one knot is buried
  7. Wait several days until you see the roots coming out of the mesh. If it’s a seed, as soon as you see the radicles popping up transplant it. With a cutting, wait until you see quite a few roots on the outside

Transplanting from Jiffy Pellets

It is very simple, in fact it is designed to facilitate the transplant among other things. The best thing is that you don’t have to take the plant out of the jiffy to put it in a pot, as is the case when transplanting cannabis from one pot to another.

In this case it is only necessary to prepare the pot where we are going to put it, to add substrate until filling up a 75% approximately, to introduce the jiffy with the plant and to add more substrate until burying all the jiffy and part of the stem.

Tips for use

The small jiffy pellets, of 24 mm. (0.94 inches) and 33 mm. (1.3 inches), are more intended for cuttings than for seed germination. This is because due to their small space the roots appear very quickly and in addition a better aeration is achieved when many clones are placed in the same tray.

On the other hand, when germinating seeds it is better for us that the jiffy is a little bigger, the 41 mm. (1.6 inches) one is perfect, because it contains more food and keeps humidity longer. The worst thing that can happen to them is that they get too dry, because then it takes a lot of time to rehydrate them.

✅ Can you use Jiffy pellets for hydroponics ?

It is not ideal, since this system needs a great aeration in the roots and jiffy does not allow this, at least at the base of the stem, so it can get to form fungi, although it would not be the first time we see it.

In this case it is much more interesting to use small grid pots with arlita to germinate and then place them in the hydroponic system. Another option is to use rockwool slabs, which allow for greater oxygenation, although we’re still sticking with the hydroponics grid pots.

Rock wool Vs Jiffy Pellets

Rock wool slabs have certain advantages as we saw before, but they have the disadvantage of being an inert material, so they need food from the first watering. Jiffy, on the other hand, contains pressed peat, which contains food for a few days, although it is always good to add root stimulator. Both are quite cheap, but it’s still cheaper to use a pressed peat or coconut pellet.

⚠️ Conclusion

A Jiffy pellet makes the job much easier for us cannabis growers and for its price it really pays off. If you have not tried them yet, I invite you to do so, because afterwards you may not want anything else to germinate, and especially to root your favorite clones.

    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.
