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.

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.

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.

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.

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.

Germinating marijuana seeds in jiffy pellets

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.

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

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.

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.)

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.

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.

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.

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

The life of any plant begins with germination, making this process the most important in your plant’s life. You will undoubtedly come across many different methods for germinating your marijuana seeds . Some may be successful, but others will disappoint you.

Why Jiffy Pellets are the Best Medium for Popping Pot 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.

How to Sprout Marijuana Seeds

Sprouting marijuana seeds in regular soil is a common practice. Soil is a natural medium and can protect the seeds as it develops its 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. Soil has both minerals and spores that supports growing marijuana plants.
