How to Top a Marijuana Plant (Step-by-Step Guide)
Purpose:
Topping promotes bushier growth, increases yield, and controls height by encouraging multiple main colas instead of one.
1. When to Top
- Stage: Vegetative stage only.
- Size: Wait until the plant has 4–6 nodes (usually 3–5 weeks old).
- Condition: Only top healthy, actively growing plants.
2. Tools Needed
- Clean, sharp scissors or pruning shears
- Rubbing alcohol (for sterilization)
3. How to Top
- Locate the main stem and count up to the 4th or 5th node.
- Sterilize your cutting tool.
- Cut just above the selected node—removing the top growth.
- Avoid cutting too low (below the 3rd node) to prevent stunting.
4. Post-Topping Care
- Allow 5–7 days recovery.
- Ensure strong light, airflow, and balanced nutrients.
- Watch for new shoots forming at the node below the cut.
5. Optional: Repeat Topping
- Wait until new tops grow 3+ nodes.
- Can be done 2–3 times for advanced training (e.g., mainlining).
6. Benefits
- Increases number of colas (bud sites)
- Improves light distribution
- Controls height and stretch
7. Risks
- Slowed growth if done too early or too often
- Infection risk from unclean tools
- Stress to plant (temporary)
Summary:
Topping is a proven method to boost cannabis yield and structure. Time it right, cut cleanly above the 4th–5th node, and support your plant during recovery for best results.
