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 ?

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 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.

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.

You don’t need to buy a Jiffy pellet tray to germinate your seeds. You can also place a jiffy pellet in a paper cup. However, if you go this route, make sure you leave plenty of room for the roots to grow by not planting your seed too deep.

They are usually sold in small packs of 12, 24, or 36. You may find larger bags of 50-200 and bulk packages of up to 2000 pellets.

The plant will also have an easier time ‘breaking its shell’ compared to when it is in a soil medium. For this method, water daily while checking the temperature, ensuring that it is around 65° F.

Jiffy Pellets are available in nurseries, online retailers such as Walmart, and garden supply stores.

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 excellent water retention capacities similar to peat, and it also facilitates healthy development of roots.

Water is another method for sprouting a marijuana seed. This method produces a seedling in 24-48 hours. The advantage of using water is that you can ensure adequate moisture for germination.

There is no risk of destroying the fragile roots of your seedlings. Therefore, you eliminate transplant stress that can lead to plant death. Are your seedlings ready to move? After placing the soil pellets in a larger growing environment, the roots will expand through the mesh and access their soil.
