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.
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.
Mother plants always stay in the vegetative stage as clones are clipped off. It’s important to not take cuttings off a flowering weed plant—this can cause the clone to turn into a hermaphrodite and may also damage the flowering plant.
If you’re using cubes of any kind, you’ll need to invest in a tray, a tray-cell insert, and a dome. The clones will go in the cubes, the cubes into the tray-cells, and all of that sits in a tray which will hold water. To keep in humidity, make sure to use a dome over your tray, and you may even want to use a heat mat.
After your clones have been properly cleaned and transplanted into their new medium, make sure to keep them quarantined for a few days to a week. Doing this will protect the rest of your garden if they do develop problems, and you’ll be able to pull them out easily.
A typical clone is about 6 inches in length, give or take, and after cutting it off the mother plant, the clone is put into a medium such as a root cube and given a hormone to encourage root growth.
Many diseases can be difficult to detect in cuttings, but there are a few visual cues that can be seen early on. A lack of vigor is a major cue—check for limping leaves, irregular or mutated growth, and discoloration.
How to take a cutting from a cannabis plant
Check under each leaf and also check the soil medium, as some pests live there. Certain pests can also leave markers—spider mites leave spots and webbing, and other insects can leave trace bite marks.
If you live in a medical or adult-use state, you’ll be able to get clones from some local weed shops, but make sure it’s a reputable shop.
Ideally, clones should be planted as soon as they get to their home. We recommend preparing the space before picking up your plants. If you do need to store them temporarily before transplanting, the following is suggested:

THINGS TO KNOW ABOUT CANNABIS CLONES
Pro Tip: Some growers reduce “transplant shock” to their clones by soaking them in a vitamin and hormone solution such as Super Thrive. Super Thrive and similar products contain vitamins and hormones that are reported to minimize stress on growing plants. Prepare a batch by mixing one gallon of water with ¼ teaspoon of concentrate. Soak clones for 15 minutes before transplanting.
The next step, which should immediately follow the initial 45 degree angle cutting, is to dip the base of the clone in a rooting hormone. Rooting hormones can come in many forms including a cloning gel, a rooting powder, or a watery mixture. Read the directions on the label for best results, and cover as much of the exposed plant tissue with gel or powder as possible.
Once your clone has a healthy root base, it can be transplanted into a larger container and the plant can then be cultivated like any other cannabis plant!
From there, cut the base of the clone at a 45 degree angle. This will help increase the surface area of the inside of the clone’s base, which is important for the next process.
The Cloning Process
For those who are new to cannabis cultivation, a cannabis “clone” is a genetically identical cutting from parent plants.
The next step is to find a branch on the cannabis plant that is suitable for cloning. Specifically, you will want to look for a branch that has new growth with at least a few sub-branches coming off of it.
Humidity Is Very Important
If you are reading this article, the chances are high that you are just starting to embark on the very rewarding journey of becoming a cannabis cultivator, or that you’re very new to cultivation. Either way, learning how to clone cannabis is a great place to start.
The process involves cutting a small branch from an already established cannabis plant, often referred to as a “mother plant,” getting it to establish its own root system, and thus become its own cannabis plant. It is important for beginner cannabis cultivators to know the process behind what goes into cloning a cannabis plant so that when they get a clone, they know what they are acquiring.
