how to splice marijuana seeds

To take a cutting:

Powdery mildew (PM) is a very common disease found on clones, and mold spores can transfer to other plants. Keep an eye out for white powder on stems and leaves.

There is some speculation that clones can degrade over time based on environment stressors and other factors, but that is open to debate.

Transplanting your weed clones

Be sure to work in a sterile environment. Use gloves and disinfect razors and scissors.

Don’t fertilize mother plants for a few days leading up to taking cuttings. This will allow nitrogen to work its way out of the leaves. When you take cuttings, an excess of nitrogen in the leaves and stems will trick your clones into attempting to grow vegetation instead of diverting energy to rooting.

If you take a clone from a plant you already have, they’re free! You just need to invest in some supplies. Although, you can buy clones from a dispensary if you want.

Grafting as a process can be traced back 4,000 years to ancient China and Mesopotamia. Although it isn’t so popular among cannabis growers, cannabis plants are perfectly suited for grafting.

Grafting involves taking the upper part of one plant (known as the scion) and attaching it to another plant (known as the rootstock).


Here’s how to graft cannabis at home. Make sure to read these instructions through a few times before getting started. Grafting is a delicate process and you’ll want to make sure you know exactly what you’re doing before you get started.

As you can imagine, grafting puts your rootstock and scion under a lot of stress. After all, it’s not exactly a “natural” way of propagating plants. Hence, you’ll want to make sure your environment is suited to meet the requirements of your new, fragile plants.

Grafting is an asexual form of propagating plants, meaning the propagated plants will preserve all the characteristics of the plant they were taken from (just like a clone preserves the same characteristics of its mother). At the same time, they’ll usually also take on some of the characteristics of the rootstock.

Step Four: Now we move on to the rootstock. Take your garden shears and cut just above your intended grafting line. Use your razor blade to make a diagonal cut in the rootstock, similar to the one you made for the scion.

Step Eight: Once your grafting site has been secured, take a plastic bag and spray the nutrient solution inside it. Wrap the bag around the grafted branch and seal it almost completely, leaving a little bit of space for airflow – just make sure the bag doesn’t come into contact with the foliage at the tip of your scion.

Step Five: Moving rather quickly, as you don’t want the insides of your plants exposed to air, give your scion and rootstock a quick spritz of nutrient solution and attach the scion to the rootstock. Make sure your scion and rootstock are lined up as perfectly as possible, giving them each enough surface area to connect.

Have The Correct Environment

One of the best reasons to start grafting marijuana plants is to grow multiple strains on one plant. If you’re from a place where there are restrictions on how many plants you can grow or how much space is allowed to grow cannabis, grafting is the answer. You can take a scion of any plant of your choice and graft it to a healthy, reliable rootstock. This will guarantee your scion will flourish, and you will be able to grow multiple strains out of one singular rootstock.

Grafting cannabis is not an easy task, and it will take your plants some time to fully take on a new scion. Grafting larger, older cannabis plants will take longer, as the full plant has had more time to mature; using young, smaller plants will be much faster if you’re looking for quicker results. In total, the time it takes for the grafting process to be complete is about 2 weeks.

The method we’ll be describing is the simplest method of grafting, called the Whip Grafting Method. You will need:

Grafting is an ancient practice within horticulture communities that is, essentially, the process of fusing two plants to create a single plant with traits of both. But how can grafting be beneficial to cannabis growers? It turns out that grafting cannabis is one of the best ways to experiment with cannabis and optimize your gardening experience. In this article, we will explain how exactly you can implement grafting in your growing practice to grow several plants in one. That’s some kind of magic!
