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. If you liked this post or think it could be useful for some other people, please share it.

Transplanting Cannabis Seedlings Into Jiffy Pellets

If your initial germination process was successful, it’s time to move your cannabis seedlings into jiffy pellets. The goal of this process is to provide new sprouts with a medium in which they can establish a small, but strong root zone.

New growers often skip the first stage of germination and sow cannabis seeds directly into moist soil, only later to be disappointed when seeds cease to sprout. This fruitless process can be caused by two reasons. First, if the soil is too wet, seeds can become waterlogged and turn to rot; second, cannabis seeds germinating in soil often have an unpredictable trajectory. If sown too deep, for example, the taproot may search for oxygen above ground and send the rest of the plant deeper into the soil. With the paper towel method, however, cannabis seedlings have the best chance of successful germination. Once the taproot is exposed, growers can avoid root rot, successfully predict the trajectory of the plant and safely transfer seedlings into their next home.

Step #1: Soak Jiffy Pellets

Jiffy’s are small, cost-effective, compressed peat pellets. Because of their size and highly porous nature, Jiffy pellets are ideal for germination. Begin the process by preparing a nutrient solution of B vitamins and water. B vitamins reduce plant stress during transition phases of growth, promote root development, and usually contain absorbable elements like potassium. About 2 liters or half a gallon of water will be sufficient for hydrating four Jiffy Pellets.

After the nutrient solution is prepared, toss your Jiffy pellets in to soak. Wait 5-10 minutes for the Jiffy’s to adequately absorb the nutrient solution. You can check if your Jiffy’s are prepared by gently squeezing the outside of the pellet. If any pieces of peat haven’t been loosened, place them back into the nutrient solution for another 5 minutes. Once the Jiffy pellets are thoroughly soaked, gently wring them out and place them to the side. Like the paper towel method, the goal of this process is not to bog down your seedlings with a soaking wet environment, but rather provide them with a moist, dark area, with high levels of humidity.

Step #2: Transplanting Seedlings Into Jiffy Pellets

Examine each sprout: if the taproot is at least ¼” long, they are ready to be transplanted into jiffy pellets. Carefully take each seedling and place them in their respective pellet with the taproot facing down. Tweezers may be useful in this task, as long as they have been sanitized beforehand with boiling water, alcohol or hydrogen peroxide. Finally, gently cover the seed shell in a small amount of soil. Do not compress any of the topsoil covering the seed. The point of layering the shell in soil is just to provide your germinating seeds with an adequate amount of darkness and humidity.

Step #3: Place Seedlings in a Germination Tray and Dome

Take your expanded jiffy pellets and place them in a standard 10” x 20” germination tray. Then, cover them with an appropriate 4” or 7” humidity dome. Since your seedlings will be living in this tray for the next 10-14 days, there are several tools available to help manage and control the environment. A light source, heating mat, and digital thermometer/hygrometers are just a few examples of tools needed to stabilize the environment within this tray. Here are some of the features of each piece of equipment:

Lighting:

Choose a low-wattage, low-intensity light source. T5 fluorescents or LED lighting is a great option to consider. At this stage, the light source is only there to encourage upward movement, not vigorous growth.

Heat Mat:

A heating mat’s purpose is to raise the temperature of a small space to an adequate level. Especially during the colder seasons, a heating mat may be essential for providing your seedlings with a constant temperature of at least 70 degrees Fahrenheit (21C). Also, consider purchasing a heat mat temperature control gauge to maximize the efficiency of your tools.

Digital Monitors:

The purpose of a digital thermometer/hygrometer is to measure the constant temperature and humidity of a given space. Some monitors even come with extended probes, allowing you to measure the temperature/humidity of specific sections of the humidity dome. For the best outcome, attempt to keep your seedlings in an environmental range of 70-75 degrees Fahrenheit (21-24C) and a minimum 70-80% relative humidity

Step #4: Set It, But Don’t Forget It

Over the next few weeks, your seedlings will begin to develop a root zone that will spread through the jiffy pellet. Also, the “true leaves” of your seedlings will begin to appear. Unlike the “sucker leaves” which first emerge from the seed shell, true leaves will be much larger, resemble typical cannabis leaves, and indicate future growth, progression and plant establishment.

This period of growth will be slow: in some cases, the transition period can take up to 14 days. So, don’t worry if you can’t see measurable growth overnight. Set your plants up for success, leave them be, but don’t forget them. Monitor your tools, control levels of temperature and humidity, and if necessary, spray your plants with a light solution of B vitamins or liquid seaweed solution. Be patient and soon enough, your seedlings will be ready to continue growing as established plants during the vegetative stage.

How to germinate cannabis seeds | peat pellet method

In our previous post we showed you how to germinate cannabis seeds using wet paper towel method. That method is good, but not perfect. To transplant those sprouted seeds you would have to touch them directly, which is not good. Freshly germinated seeds are like babies, you wouldn’t want to touch fetus with your hands that have oils and dirt on them. Same goes for sprouted seeds. It has to be sterile, so you would want to make as less direct contact with it as possible.

Freshly sprouted cannabis plant

Lets talk how to germinate cannabis seeds using peat pellets. We highly recommend using this method over wet paper towel method as this one is safer can gives you a better success rate.

For this to work you will need peat pellets, you can find them in any gardening store or order them online. These pellets contain lots of nutrients for your freshly sprouted seeds. They come in small, dry, compressed pellets. Peat pellets are not very expensive and definitely worth the price. They look like this:

How to germinate cannabis seeds using peat pellets – process

Once you have the pellets it’s time to prepare them. Soak them with water, we suggest that you’d use distilled water as tap water contains a lot of stuff that is not very good for these fragile younglings. Leave them for about 10 minutes and they will expand.

After 10 minutes (+/-) they should look something like this —>
You can plant your seeds in them. Use a pen to make small holes in them, about 1/2 inch deep. Put your seed using pair of tweezers in that hole and cover it up. One pellet should hold one seed for best possible results.

When you plant seeds into wet pellets, they begin their life. You should see them sprouting in 2-7 days period. Throughout this time, keep the pellets moist and warm ( 20-25°C). If they dry out, that might be the end of it. If you get good quality seeds, there’s nearly 100% success rate that they will germinate.

How to germinate cannabis seeds using peat pellets – next step

So your seeds have sprouted after 2-7 days. What’s next ? When you seed that your seeds popped out, you need to put them under direct light, cause once they pop, they crave for that light. Will it be grow light or sunlight, that’s entirely up to you and your chosen growing method. You need to do one more thing – transplant them into pots. Don’t pull them out of the pellet, there’s a very good chance you will destroy the plant. Just bury plant with the whole pellet. Roots will eventually go straight through pellet.

Transplanted cannabis plants

Congratulations! You’ve germinated some seeds. Now let ’em babies grow.

Where to get good quality seeds?

We have been using the service of “I love growing marijuana“. They ship very good quality seeds , and if you buy 10 or more seeds they throw in 10 more free off charge. They ship seeds worldwide, but if you live in a country that don’t have marijuana legalized, be cautious, make sure no one finds out about it. Be smart, be safe.
