How to Clone Cannabis: 13 Steps
Cannabis cloning is a popular method used by growers to propagate plants and ensure a steady supply of genetically identical clones. This process allows cultivators to preserve specific desirable traits and maintain strain consistency. Here is a step-by-step guide on how to clone cannabis plants.
1. Choose a healthy mother plant: Select a robust, disease-free plant with the desired characteristics, such as high yields, potency, and terpene profile.
2. Clean your workspace: Ensure your workspace is clean and sterile to prevent contamination or diseases that could harm your clones.
3. Gather necessary supplies: You’ll need a sharp pair of scissors or scalpel, rooting hormone, rapid rooter starter plugs or rockwool cubes, a cloning tray with lid, spray bottle for water, and a heat mat (optional).
4. Prepare new growth medium: Soak rapid rooter plugs or rockwool cubes in pH-balanced water for about an hour before use.
5. Select donor branches: Choose young branches with healthy growing tips from the mother plant. Look for branches that have at least two nodes (the point where leaves emerge) and are about 5-8 inches long.
6. Cut the donor branch: Use a sterilized tool to make a clean cut at a 45-degree angle below the selected node on the chosen branch.
7. Trim excess leaves and growth: Remove large fan leaves leaving only tiny leaves at the top of each cutting, thereby reducing transpiration while directing more energy toward root development.
8. Apply rooting hormone: Dip the trimmed end of each cutting into a rooting hormone solution to encourage rapid root formation.
9. Insert cuttings into growth medium: Gently insert each cutting into pre-soaked rapid rooter plugs or rockwool cubes, ensuring secure contact between the stem and medium.
10. Maintain humidity levels: Place cuttings in a cloning tray, and cover them with a lid to create a humid environment. Mist the cuttings with water periodically to increase humidity.
11. Monitor temperature: Maintain an ideal temperature range between 70-80°F (21-27°C) by using a heat mat if necessary.
12. Provide light: Supply indirect light for 18-24 hours per day using low intensity LED, CFL, or fluorescent lights.
13. Watch for root development: Check root development after 7-14 days and transplant the clones into a larger growing container once roots are visibly established.
By following these 13 steps, you’ll be able to clone cannabis plants successfully and enjoy consistent high-quality yields from genetically identical plants. Remember always to monitor your clones’ health and provide proper care throughout the process.
