Here’s a general standard operating procedure (SOP) for cutting cannabis clones.

1. Gather the necessary tools and supplies: You will need a clean, sanitized cutting tool (such as a sharp knife or razor blade), rooting hormone, clean propagation trays or pots, a rooting medium (such as rockwool cubes or peat pellets), a spray bottle with water, and labels for identification.
2. Select healthy mother plants: Choose mature cannabis plants with desirable characteristics, free from diseases, pests, or nutrient deficiencies. Ensure the mother plants are well-hydrated before taking cuttings.
3. Prepare the cutting area: Clean and sanitize your workspace, including tools, trays, and containers, to prevent contamination and the spread of diseases. A bleach solution or isopropyl alcohol can be used for sanitization.
4. Take the cuttings: With a sharp and sterile cutting tool, make a clean cut just below a node or leaf set on a healthy branch. Cuttings should be around 4-6 inches long and should include at least two nodes.
5. Remove excess foliage: Trim away excess leaves from the lower portion of the cutting, leaving only a few at the top. This helps reduce moisture loss and allows the cutting to focus its energy on root development.
6. Apply rooting hormone: Dip the bottom 1-2 inches of each cutting into rooting hormone powder or gel, following the product instructions. This encourages root growth and improves the success rate.
7. Insert cuttings into the rooting medium: Make small holes in the rooting medium using a pencil or similar tool. Gently insert the treated end of each cutting into the hole, ensuring good contact between the cutting and the medium.
8. Mist the cuttings: Use a spray bottle to mist the cuttings with water, creating a humid environment. This helps prevent excessive moisture loss through the leaves until roots form.
9. Label and place the tray in a suitable environment: Label each tray or pot with the corresponding strain or identification code. Place the tray in a propagation area with controlled temperature, humidity, and light conditions suitable for rooting cannabis clones.
10. Provide proper care and monitoring: Ensure the cuttings are kept moist but not overly saturated. Maintain the appropriate temperature and humidity levels, typically around 70-80°F (21-27°C) and 70-80% humidity. Monitor the clones regularly for signs of root development and adjust care as needed.
11. Transplant rooted clones: Once the cuttings have developed strong root systems (usually within 2-3 weeks), they are ready for transplanting into larger containers with a suitable growing medium. Continue providing optimal care to promote healthy growth.

Remember, this SOP is a general guideline, and specific techniques and conditions may vary depending on your setup, strains, and preferences. It’s important to stay informed and adapt your methods based on the best practices in cannabis cultivation.
