Learn how to clone a cannabis plant so that you can have an identical genetic copy of your favorite plant. This process is known as vegetative propagation and is a great way to ensure you always have a steady supply of your favorite cannabis strain.

Choose a healthy mother plant.
The first step to cloning a cannabis plant is to choose a healthy “mother” plant from which to take your cutting. You can clone any type of cannabis plant, including indica, sativa, and hybrid strains. However, some growers prefer to clone certain strains because they are known to produce strong, healthy clones .
When selecting a mother plant, look for one that is vigorous and has big, healthy leaves. The plant should be free of pests and diseases, and it should be in the vegetative stage of growth (not flowering). It’s also a good idea to choose a mother plant that is at least 3-6 weeks old, as younger plants may not have developed enough roots to support clones.
Once you’ve selected a mother plant, you’ll need to take a cutting from it. Cuttings should be taken from the tips of branches that have at least 2-3 sets of leaves. Using sharp scissors or a razor blade, cut the stem at an angle just below a set of leaves.
Take a cutting from the mother plant.
To clone a cannabis plant, you will need to take a cutting from the mother plant. It is best to take the cutting from a healthy, mature plant that is at least 6 weeks old. The ideal time to take the cutting is in the morning, after the dew has evaporated but before the sun gets too hot.
You will need a sharp knife or pair of scissors to take the cutting. Cut a branch that is about 4-6 inches long. The branch should have at least 2 sets of leaves. Make sure to sterilize your knife or scissors with alcohol before taking the cutting, and disinfect the cutting tool afterwards as well.
Once you have taken the cutting, remove the lower leaves so that only 2-3 sets of leaves are left on the stem. Dip the cut end of the stem into rooting hormone powder or gel, then plant it in a pot filled with moistened grow media such as perlite or vermiculite.
Water the media around the stem lightly, then place the pot in a warm location out of direct sunlight. Keep an eye on the moisture level of the media, and water as needed to keep it moist but not soggy. Within a few weeks, you should see roots beginning to form and new growth appearing on the cutting. Once this happens, you can transplant your clone into its final growing location.
Prepare the cutting.
You will need to take a sharp knife and cut a 45-degree angle about 2” below a node on the mother plant. A node is where the leaves branch off the stem of the plant. You want to make sure that there are no leaves on the section of stem that you are going to cut. If there are leaves, you will need to remove them. After you have made your cut, you will need to dip the end of the cutting in rooting hormone. This will help encourage root growth once you have planted the cutting.
Plant the cutting.
Choose a planting medium and fill your cloning container with it. cannabis can be cloned in rockwool, perlite, vermiculite, coco coir, soil, or even deep water culture. If you’re using a soiless medium like rockwool or coco coir, you’ll need to soak it in water for about 15 minutes before planting.
Once your planting medium is ready, make a small hole in it with your finger or a pencil and insert the cutting so that only the top few leaves are sticking out. Gently firm the medium around the base of the cutting.
Next, you’ll need to create a humid environment for your cutting to help prevent it from drying out. There are several ways to do this:
-Place the container inside a larger container or plastic bag and cover it with a lid or plastic wrap. Make sure that there is some space between the two containers so that air can circulate.
-Use a humidity dome or tent. These are specially designed to create a humid environment for plants and can be purchased at most garden stores.
-Make your own mini greenhouse by covering the container with clear plastic wrap or a clear jar lid and setting it in a sunny spot.
Monitor the progress of the clone.
The first thing you will want to do is monitor the progress of the clone. You will want to make sure that the clone is taking root and is growing healthy. After a week or so, you should see new growth on the clone. If you do not see any new growth, then you will want to check the roots to make sure they are healthy.
