How to Clone Marijuana the Right Way

how to clone marijuana

Duplicating beautiful flowers is not only exclusive for florists. Cannabis growers can no doubt do it too. It is through their knowledge of how to clone marijuana. It’s a simple process that can be done quickly. 

It’s also economical as you don’t need to keep on buying seeds in situations where you don’t want a new variety. When you make several clones from a single marijuana plant, you can boost the amount of yield.

Definition of Cloning

Cloning marijuana starts with cuttings. It is done in the way of asexual propagation. It’s producing a photocopy of something. Most ordinary gardeners are familiar with it and do it a couple of times.

Since it is a duplicate of the mother plant, it is as old as her. The clones can’t be improved or worsened as they only copy everything from the source. If you keep on using the single plant, it will never fail to give you the same quality. There’s a record of clone reproduction successfully done 50 times as it was all from a healthy specimen.

Reasons for Cloning Marijuana Plants

1. Genetic Preservation

Select a mother plant and the phenotype of your choice for repetitive cloning. You have to carefully pick her, and she must be kept in vegetation. If there’s an existing crop on her, you can let it develop.

2. The Cycle of the Crop

When you clone marijuana, you also allow the rotation of the crop, or it’s like a cycle. The earlier batch can be in the flowering stage while the succeeding plants are still in vegetation. It works well if you wish to have a perpetual harvest.

You don’t have to preserve the mother plant as you only need to take cuttings before you switch to a 12/12 light schedule. Just let the new batch begin to root while the others are in bloom. 

3. Goals of Breeding

Some marijuana growers are interested in breeding, and some are not. It all depends on your objectives and preference. But you should know that a clone is the best breeding stock as it went through trials and tests.

Most growers set up a suitable environment for their clones. Some would put mature plants in a large grow tent, and cuttings are places in a smaller tent.

Procedures on How to Clone Marijuana

Necessary Tools and Materials:

Plant clippers or scissors will be fine

Starter cubes

Rooting hormone or cloning gel


Scalpel (not necessary)

Guide on How to Clone Marijuana

1. Select a robust plant of your choice, and it must be in the vegetative period. You have to inspect the plant for desirable traits. Choose wisely, and don’t settle for less. Every marijuana grower wants fast-flowering, vigorous growth, productive, and of course, potent.

2. You should collect the tools and materials that were mentioned above. You may use a scalpel, but it’s not your main weapon. Staying simple is good.

3. Use your scissors or plant clippers to cut a healthy branch from a mother plant. Do it tidily. You can also go over the bottom branches. Aside from giving way to the airflow, you can get more clippings for cloning.

Lower branches are the oldest among the rest, and they are deemed to root well. If they won’t proceed with a successful growth, it’s fine as there’s a lot on your mother’s plant. It’s a win-win situation when you start with the bottom part.

4. Excess leaves and stems should be cut. The recommended size of the clone is 10 cm because it’s practical, and you can keep it properly in a propagator. 

Target the branch’s node, and the cut should be done at a 45-degree angle for expanding the surface of the root. Dip the cut area into growth hormone or rooting gel for 3 seconds. 

5. Use a pen, a nail, or something that can make a hole in the soil, which should be moist. You have to house the cuttings well in the propagator. 

Press the soil that surrounds cutting gently. Water them if it’s necessary.

6. You have to trim the leaves, which are about a third of the remaining ones. You have to remember that it’s no longer a branch but a micro plant. With this conventional way of cloning, you can expect the clippings to root in one to 3 weeks.

Growing Medium Used on How to Clone Marijuana 

1. Rooting Cube

It is the growing medium that most marijuana growers depend on. It can easily be transplanted into any kind of final medium. It’s also great with planting directly into coco or soil, but you need to use 0.5 to 2 L. 

A medium should maintain the dampness, and it shouldn’t be waterlogged. But the rooting cube only needs to be watered sparingly. It stores enough nutrients for the clones in the first three weeks.

2. Peat Dust Pot

You can make this yourself by using a third of compost, cutting or seed soil, and perlite. The compost contains a lot of nutrients, while perlite is used for aeration. Fill the pots with a mixture of these three things. 

The pots should be moist and place them under the light to achieve the right temperature. Rooted clones don’t need much light as they only use warmth to grow roots. The roots need around 20 to 25 degrees Celsius.

A soil warmer in the form of a cable or mat would help you provide the temperature that the roots require. To check the temperature, an aquarium thermometer can help you.

3. Rock Wool

It is one of the popular growing mediums used for clones. It’s easy to use, but it gives favorable results. You need to soak it in water with a pH of 5.5 for 2 hours before using it.

Your clones in rock wool would take 7 to 12 days to root. You should see to it that the humidity level is over 90%. The temperature should stay around 22 to 24 degrees Celsius.

4. Cloning with Water

Another way you can do on how to clone marijuana is by water. It’s simple, and you need to keep the cuttings away from indirect light. Then you will find that the roots have grown after 2 or 3 weeks.

You have to maintain the cleanliness of the water, so you would need to change it every day. The pH level should be 5.5.

The Care Needed by Marijuana Clones


The clone should be given 18 hours or more of MH or CFL light for optimal growth. The light shouldn’t be in high wattage as something intense doesn’t work well. It’s fine that clones are slightly shaded as they can still root.


High humidity, which equals 70% is great for clones. A cool temperature of 20 to 25 degrees Celsius can protect them from any stress. They would flourish in a sunny window sill.

Investing in a propagator is indeed a good idea. It’s not too expensive, and you can save some space. Some models feature LED lights in it. They are great self-contained habitats.

How Would You Take Care of Your Marijuana Clones

You have to keep your clones moist and good in the first week. A regular dose of nutrition is helpful, and you have to spray the plant with it. You can make a solution to one liter of water and a teaspoon of fish emulsion. After the feeding, spray them with water for cleansing.

You will see poking roots at the base of the pot after ten to two weeks. When you use small pots, you can take them out for transplanting. You can let the ones in the bigger pot to stay a bit longer. They can be re-potted in pots with 10 to 20 centimeters of diameter.

Before you transplant them, make sure that they are wet so the roots can grow easily. You need to label the pots to avoid mixing up the varieties.


Patience is what it takes to accomplish things on how to clone marijuana. Make sure you get the clippings from the mother plant before flowering time. You have to keep an eye on them. Mold formation may happen.

The clones won’t thrive if the growing environment doesn’t suit them. Let them stay moist by misting them often.
