Cannabis cloning is a powerful tool that allows growers to preserve and replicate their favorite strains with precision and consistency. By mastering the art of cloning, cultivators can ensure a steady supply of genetically identical plants, all possessing the desired traits of the carefully chosen mother plant. 

Cloning stands as an age-old practice that holds the key to replicating nature's finest treasures. The art of cloning cannabis allows growers to harness the very essence of their favorite strains, preserving their unique genetic makeup and ensuring a consistent harvest of top-tier buds. Whether you are a seasoned cultivator seeking to perpetuate the traits of a cherished mother plant or a budding enthusiast eager to embark on a horticultural adventure, mastering the intricacies of cannabis cloning is a skill worth honing.

Understanding Cloning

Cloning involves taking a cutting, or a small branch, from a healthy, mature cannabis plant (typically referred to as a mother plant), and encouraging it to develop roots and grow into a new, independent plant. This process allows the new plant to inherit the exact genetic makeup of the mother plant.

Materials Needed:
  1. Healthy mother plant: Choose a mature, healthy cannabis plant that exhibits the characteristics you wish to preserve.
  2. Clean razor or scalpel: To make precise and clean cuts.
  3. Rooting hormone: A rooting hormone gel or powder will promote root growth on the cutting.
  4. Cloning gel or powder: It helps prevent infections and aids in the development of root systems.
  5. Growing medium: A suitable mix like perlite, vermiculite, or a combination of these with peat moss or coco coir.
  6. Propagation tray or pots: To hold the cuttings while they develop roots.
  7. Humidity dome or plastic wrap: To create a humid environment, essential for successful rooting.
  8. Spray bottle: To maintain humidity levels and provide water as needed.
  9. Light source: Fluorescent or LED lights to provide the cuttings with the necessary light.

Step-by-Step Cloning Process

  1. Selecting the Mother Plant:

    • Choose a healthy mother plant with desirable traits like flavor, aroma, potency, and yield.
    • Ensure the mother plant is free of pests, diseases, and nutrient deficiencies.
  2. Preparing the Cutting:

    • Use a sharp, clean razor or scalpel to take a cutting from the mother plant.
    • Choose a young, healthy branch that has at least two to three nodes (where leaves emerge).
    • Make a clean, diagonal cut just below a node. Avoid crushing or damaging the stem.
  3. Applying Rooting Hormone and Cloning Gel:

    • Dip the cut end of the stem into rooting hormone to encourage root growth.
    • If using cloning gel or powder, follow the manufacturer's instructions to apply it to the stem.
    • Some people opt not to use any kind of cloning gel, this often works but may take longer for the cutting to root
  4. Planting the Cutting:

    • Place the cutting into a pre-soaked growing medium like rockwool, a rooting plug (such as Rapidrooter or another brand), perlite, vermiculite, or a mix of these with peat moss or coco coir.
    • Gently press the medium around the cutting to ensure it stands upright.
  5. Creating a Humid Environment:

    • Cover the cuttings with a humidity dome or loosely place plastic wrap over the propagation tray to retain moisture.
    • This helps maintain a high humidity environment, crucial for root development.
    • Keep the clones in the humidity dome for at least 3 days before removing or opening the vents
  6. Providing Light and Water:

    • Place the cuttings under fluorescent or LED lights to encourage growth.
    • Keep the medium consistently moist, but avoid overwatering, as this may lead to rot.
  7. Root Development and Transplanting:

    • In about 1-3 weeks, the cuttings should develop roots.
    • Once the roots are well-established, the clones can be transplanted into individual pots with a suitable growing medium.

Cloning Timeline

Day 1-3:
  1. Prepare the clones: After taking the cuttings, trim any excess leaves, leaving a few fan leaves intact to support initial growth.

  2. Create a humid environment: Place the clones in a humidity dome or cover them with plastic wrap to maintain high humidity levels. This prevents excessive moisture loss through transpiration as the clones have not yet developed roots to take up water.

  3. Light and temperature: Place the clones under a gentle light source, such as fluorescent or LED lights, for 18-24 hours per day. Maintain a temperature of around 72-78°F (22-26°C) to encourage rooting.

  4. Mist the clones: Use a spray bottle to mist the clones and maintain a moist environment within the humidity dome.

Day 4-7:
  1. Observe for signs of rooting: After a few days, check for signs of rooting. New growth or white root tips emerging from the bottom of the cloning medium indicate successful rooting.

  2. Reduce humidity gradually: Open the humidity dome or remove the plastic wrap for short periods each day to gradually reduce humidity. This helps the clones acclimate to lower humidity levels over time.

  3. Maintain proper lighting: Continue providing 18-24 hours of light per day to encourage strong root development.

  4. Avoid overwatering: Check the cloning medium's moisture level regularly and water only when it feels slightly dry. Overwatering can lead to rot and hinder root growth.

Day 8-14:
  1. Monitor root development: Continue monitoring the clones for root growth. They should start developing a network of roots within this timeframe.

  2. Transplant if necessary: If the clones have outgrown their initial containers or started showing significant root development, consider transplanting them into individual pots with fresh growing medium.

  3. Gradually decrease light exposure: If the clones have rooted successfully, reduce the light exposure to 16-18 hours per day to simulate the natural light cycle.

  4. Start light fertilization: If your growing medium is nutrient-free, begin introducing a diluted, balanced nutrient solution to support the clones' growth.

Day 15 and beyond:
  1. Gradual hardening: If the clones have been growing indoors & will be kept outside, gradually expose them to outdoor conditions if you plan to move them outdoors. This process, called "hardening off," helps the plants adjust to the new environment.

  2. Continue monitoring and care: Regularly check the clones for signs of nutrient deficiencies, pests, or diseases. Adjust watering and nutrient schedules as needed to promote healthy growth.

  3. Transplant to final growing location: Once the clones have developed strong root systems and are well-established, transplant them to their final growing location, whether it be indoors or outdoors.

  4. Maintain proper care: Continue providing appropriate light, water, and nutrients to ensure your cloned cannabis plants thrive and reach their full potential.

Remember, successful cloning requires patience, attention to detail, and consistent care. With proper nurturing, your clones will grow into healthy, robust plants that showcase the desirable traits of their mother plant.



Cloning cannabis plants is an effective way for growers to replicate their favorite strains with precision and consistency. By following these step-by-step instructions and providing the proper care and attention to the cuttings, cultivators can ensure a successful cloning process and grow healthy, genetically identical cannabis plants. Remember to choose a strong and healthy mother plant, maintain a humid environment during the initial stages, and provide adequate light and water to the cuttings. With practice and patience, mastering the art of cloning can elevate your cannabis cultivation skills to new heights. 

Remember, patience and diligence are key when caring for clones. Observing and adjusting environmental conditions, along with keeping an eye out for any signs of stress, disease, or nutrient deficiencies, will ultimately lead to healthier and more robust cannabis plants.

As you embark on your journey into cannabis cultivation, cloning offers a valuable opportunity to perpetuate the genetics of your most cherished strains. As you become more proficient in the art of cloning, you will be able to refine and expand your cannabis garden with confidence and finesse.

In the world of cannabis cultivation, the art of cloning remains a timeless and essential skill for growers. By unlocking the potential to clone cannabis, you gain access to an ever-expanding array of possibilities, both in terms of crop diversity and genetic preservation.
