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:
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.
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.
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 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.
- Place the seeds in the glass.
At first, seeds will often float on the surface. They should sink to the bottom of the container after a couple of hours. Soaking ensures that water penetrates the protective shell to activate growth hormones.
- 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.
