What Is Marijuana Cloning?
Marijuana cloning is a horticultural technique used to create genetically identical copies of a marijuana plant. It involves taking a cutting or “clone” from a healthy, mature marijuana plant and encouraging it to root and grow as a new plant.
Cloning allows growers to replicate the desirable traits of a particular cannabis plant, such as potency, flavor, or yield, without relying on marijuana seeds. This process can help maintain consistency and quality in cannabis cultivation.
The Benefits of Cloning Marijuana
Cloning marijuana offers several benefits to growers:
Replication of Superior Genetics
Cloning allows growers to replicate the genetics of a high-quality, desirable mother plant. This ensures that the cloned plants inherit the exact traits, such as potency, flavor, or yield, that make the mother plant exceptional.
Control Over Plant Gender
When growers clone, they can ensure the gender of the new plants, as they’ll be identical to the mother plant. This is particularly useful in cannabis cultivation, where female plants are typically desired for their cannabinoid-rich flowers.
Disease and Pest Resistance
Cloning from a healthy mother plant can pass on resistance to diseases and pests to the new plants. This reduces the risk of infestations and the need for pesticides.
Efficient Use of Space and Resources
Cloning allows growers to maximize space and resources, as they can maintain a perpetual cycle of plants without the need to germinate new seeds. This is particularly useful for those with limited cultivation space.
With a consistent supply of cloned plants at different growth stages, growers can achieve a continuous harvest. This steady production can be essential for meeting market demand and maintaining a regular supply of cannabis products.

How to Clone Marijuana
Here’s a step-by-step guide on how to clone marijuana:
Selecting the Right Plant
Select a mature marijuana plant with desirable characteristics. It should be disease-free and free of pests.
Preparing the Plant
- Gather Your Cloning Tools: Ensure you have a clean workspace and all the necessary tools and materials.
- Take Cuttings: Using a sterilized razor or scalpel, cut 4-6 inch (10-15 cm) branches with at least two nodes (the areas where leaves or branches grow) from the mother plant. Trim away excess leaves, leaving a few at the top.
Rooting the Plant
- Apply Rooting Hormone: Dip the cut end of each clone into a rooting hormone gel or powder.
- Place in Rooting Medium: Insert the treated clones into pre-soaked rooting cubes or plugs. Put them in a tray or rack, and cover with a humidity dome to maintain high humidity.
- Provide Light and Maintain Temperature: Place the clones under a fluorescent or LED light and maintain a temperature around 75-80°F (24-27°C) for optimal rooting.
Watering and Waiting
- Mist Clones: Keep the environment humid by misting the clones regularly.
- Monitor and Adjust: Check for roots by gently tugging on the clones after about 10-14 days. Once you feel resistance, roots have formed.
- Transplant to Vegetative Stage: Once the clones have well-developed roots (1-2 inches or 2.5-5 cm), transplant them into larger pots with soil or a suitable growing medium.
- Move to Vegetative Growth: Continue growing the rooted clones under 18-24 hours of light to encourage vegetative growth.
- Maintain Care: Water, fertilize, and provide appropriate light until the clones are ready for the flowering stage.
Cloning Marijuana: Tips for Success
To ensure successful marijuana cloning, consider these tips:
Timing and Season for Cloning
Clone during the vegetative growth phase for the best results. Choose a consistent time of year to maintain environmental conditions, which can be more challenging in extreme seasons.
Proper Cutting Techniques
Use a sharp, sterile blade to make clean cuts. Take cuttings from the lower branches as they tend to root more easily. Trim excess leaves to reduce moisture loss and focus energy on root development.
Managing Light and Humidity
Provide 18-24 hours of light during the vegetative stage. Maintain high humidity within the humidity dome or tray, around 70-80%, to prevent wilting.
Ensuring Adequate Air Circulation
While high humidity is essential, ensure there’s some airflow within the humidity dome or propagation area to prevent mold and rot. Use fans to gently circulate air without over-drying the clones.
Rooting Hormones and Stimulants
Use a rooting hormone (gel or powder) to promote root growth, but avoid excessive application.Some growers also use beneficial mycorrhizal fungi to enhance root development.
Cloning Marijuana: Common Problems
Cloning marijuana can come with its share of common problems. Here are some issues to be aware of:
Not sterilizing your cutting tools or workspace can introduce pathogens that harm the clones. Cleanliness is crucial.
Improper Cutting and Handling
Cutting too close or too far from nodes, damaging the delicate cuttings, or not trimming excess leaves can lead to lower success rates.
Neglecting Environmental Control
Inconsistent temperature, humidity, or light can result in poor root development or stressed clones. Maintain optimal conditions.
Neglecting Root Health
Failure to provide proper nutrients, overwatering, or underwatering can lead to unhealthy root systems, causing the clones to wither.
Poor Timing and Vigilance
Waiting too long to transplant rooted clones, or not checking for root development, can hinder the success of your cloning process.
Cloning Marijuana vs. Growing From Seed
Cloning marijuana and growing from seed each has its advantages and considerations:
- Genetic Consistency: Cloning allows you to replicate the exact genetic traits of a desirable mother plant, ensuring consistency in characteristics like potency, flavor, or yield.
- Faster Growth: Clones already have a head start as they skip the germination phase and usually mature faster than seeds.
- Gender Control: Cloning guarantees the gender of the plants, which is important if you want female plants for their flower production.
Growing From Seed
- Genetic Diversity: Seeds provide genetic diversity, which can be desirable if you’re breeding or looking for unique phenotypes.
- Less Risk of Disease and Pests: Seeds bought from reputable cannabis seed banks are less likely to carry over diseases or pests from a mother plant.
- Taproot Development: Seed-grown plants typically develop taproots, which can make them more stable and resilient.
Cloning With Hydroponics
Cloning with hydroponics is a method that involves using a soilless growing system to encourage root development in your cannabis cuttings. Here’s a basic overview of how to clone marijuana with hydroponics:
Materials and Steps
- Hydroponic System: Set up a hydroponic cloning system, which can include aeroponics, deep water culture (DWC), or a similar system designed for clones.
- Growing Medium: Instead of traditional soil, use a soilless growing medium like rockwool cubes, oasis cubes, or neoprene inserts, which work well in hydroponic systems.
- Rooting Hormone: Apply rooting hormone to the cut ends of your clones to stimulate root growth.
- Humidity Dome: Place the cuttings in a humidity dome within the hydroponic system to maintain a high humidity environment.
- Maintain Light and Temperature: Provide appropriate lighting (typically 18-24 hours of light) to support vegetative growth and maintain an optimal temperature range around 75-80°F (24-27°C).
- Nutrient Solution: Ensure your hydroponic system is equipped with the right nutrient solution for young plants.
- Monitor and Adjust: Regularly check the clones for root development and overall health. Adjust nutrient levels and maintain the hydroponic system as needed.
Using Seed Grow Kits for Clones
Seed grow kits are typically designed for germinating and growing cannabis plants from seeds, not for cloning. Cloning involves taking cuttings from an established plant to create genetically identical copies.
However, you can adapt a seed grow kit for cloning with some modifications. Here’s how:
- Select a Suitable Kit: Choose a seed grow kit with components that can be adapted for cloning, such as a grow tray, humidity dome, and lighting.
- Prepare the Cuttings: Instead of seeds, take cuttings from a healthy mother plant. Use a sharp, sterilized blade to cut the branches, and apply rooting hormone to the cut ends.
- Growing Medium: Replace any seed-starting medium in the kit with a suitable substrate for clones, like rockwool cubes or Oasis cubes. Place your cuttings in these cubes.
- Humidity Dome and Lighting: If the kit includes a humidity dome and lighting, use them to create the right environmental conditions for your clones. Ensure the dome retains high humidity.
- Temperature and Airflow: Monitor and adjust the temperature within the kit to maintain the ideal range for cloning (around 75-80°F or 24-27°C). If the kit has air vents, use them to manage airflow while maintaining humidity
- Nutrient Solution: If the kit includes a built-in hydroponic or nutrient delivery system, you may need to adapt it for clone-specific nutrient needs.
