Cannabis Cloning: Propagating Potency and Precision

In the realm of cannabis cultivation, cloning stands out as an efficient and precise method to ensure consistency in quality and yield. It’s a reproduction technique that sidesteps the unpredictability of seeds, offering growers a surefire way to continue a desired trait or strain. In this article, we’ll explore cannabis cloning and the various methods you can employ for successful propagation.

What is Cannabis Cloning?

Cloning is a horticultural technique where a cutting from a “mother” plant is taken and rooted as a separate plant. The clone, once established, will be a genetic duplicate of its parent, ensuring that characteristics like potency, flavor profile, and growth habits remain consistent.

Benefits of Cloning:

  1. Consistency: By using clones, growers can maintain the genetic consistency of a particular strain.
  2. Cost-Efficient: Cloning can be more economical than purchasing seeds, especially for large-scale cultivation.
  3. Faster Growth Cycle: Clones often mature faster than plants grown from seeds, shortening the time to harvest.

Methods of Cloning Cannabis:

  1. Traditional Soil Cloning:
    • Taking the Cutting: Select a healthy mother plant. Using sterilized scissors, take a cutting of 5-8 inches from a branch’s tip.
    • Rooting Hormone: Dip the cut end into a rooting hormone. This promotes root development.
    • Planting: Insert the treated cutting into a pot with fresh, moist potting soil.
    • Environment: Keep the cutting in a humid environment. A plastic dome or plastic bag can help retain moisture.
  2. Rockwool Cloning:
    • Preparation: Rockwool cubes should be soaked in pH-balanced water (around pH 5.5 to 6.5) to prepare them for the cutting.
    • Taking and Treating the Cutting: As with soil cloning, select a healthy cutting and treat with a rooting hormone.
    • Insertion: Place the treated cutting into the pre-soaked Rockwool cube.
    • Environment: Retain humidity around the clone using a plastic dome or bag.
  3. Water Cloning:
    • Taking the Cutting: As before, select a healthy cutting from the mother plant.
    • Placement: Place the cutting directly into a container with clean water, ensuring the cut end is submerged. No rooting hormone is necessary.
    • Changing the Water: Refresh the water every few days.
    • Observation: In 1-2 weeks, you should see roots beginning to form. Once established, you can transplant the clone to soil or another medium.
  4. Aeroponic Cloning:
    • The System: An aeroponic cloner is a system where cuttings are suspended in air and misted with nutrient-rich water. This can create an optimal environment for root development.
    • Taking and Placing the Cutting: Obtain a cutting, treat with rooting hormone, and place it in the aeroponic system.
    • Misting: The system will mist the cuttings at regular intervals, encouraging root growth.
  5. Use of Propagation Kits: These are commercially available kits that provide a controlled environment for clone growth, often using a combination of the above methods. They can be an excellent option for beginners or those looking for a more hassle-free cloning experience.

Tips for Successful Cloning:

  • Mother Plant Health: Always select a healthy, vigorous mother plant for cloning. Diseases or pests can be transmitted to clones.
  • Sterilize: Ensure that scissors, blades, and other tools are sterilized to prevent infection.
  • Monitor Humidity: High humidity (around 70-80%) is vital in the early stages of cloning to prevent cuttings from drying out.
  • Avoid Overwatering: While moisture is crucial, overwatering can lead to mold and root rot.


Cloning offers an exciting avenue for cannabis cultivators to maintain strain integrity and streamline their growing process. Whether you’re a novice grower or a seasoned expert, understanding the art and science of cloning can be a valuable asset in your cultivation toolkit. With patience and practice, you can master this method and ensure a consistent, high-quality cannabis harvest.
