How to Top Cannabis Plants & When Is the Best Time
Share
Topping is one of the most successful plant training techniques for cannabis growers seeking higher production and bushier plants. Growers can encourage more colas by carefully cutting the main stem. The big question is: When and how should you top cannabis plants? Let us explore the process in detail.
What Is Topping?
Topping is the process of cutting off the tip of the main stem during the vegetative phase of a marijuana plant. This forces the plant to divert its energy towards two new branches and disrupts its natural upward growth. The plant becomes bushier, and more buds are produced.
Topping vs. FIM
- Topping: Produces 2 new colas with one cut.
- FIM is short for "Fk I Missed Less precise cutting that can create 3-4 new colas, but stresses the plant.
Why Top Cannabis Plants?
- Better Light Distribution- A top plant grows wider, allowing for more light to reach lower limbs.
- Higher Yields- More colas means more buds and possibly larger harvests.
- Height control- Topping is a great way to prevent cannabis plants from becoming too tall. This is particularly useful indoors.
- Even Canopy- Creates a uniform and level top to allow for better light penetration.
When to Top a Cannabis Plant
Vegetative Stage Is Essential
Top cannabis only when the plant is in vegetative growth. Topping should be done only when the plant is in vegetative development. This usually occurs between weeks 3 - 6 after germination.
Node-Based Timing
Nodes are places where stems and leaves grow outwards. The right timing is crucial.
- 4-5 Nodes: A Common and Safe Stage for Beginners
- The 6th node is often considered to be the best point for the plant, as it gives the plant the strength needed to recover quickly.
- 5–7 nodes: This flexible window is preferred by many growers to balance growth and resilience.
Avoid Late Topping
Topping may stress the plant, slow down bud growth, and decrease production once it starts to produce flowers.
How to Top Cannabis Plants Step-by-Step
Step 1: Prepare the Tools
- Use sharp, clean scissors or pruning shears.
- To prevent infections, sterilize them with rubbing alcohol.
Step 2: Select the Right Place
- Find the main stem.
- Count up to 4-6 nodes from the base.
- Plan your cut over the node that you have selected.
Step 3: Cut the Shirt
- Cut the stem at the node.
- To avoid damaging the node, leave a small stub.
Step 4: Optional Pruning
Some growers remove their plants' first (lowest node) to encourage them to focus on stronger branches.
Step 5: After-Topping Care
- Make sure the plant gets enough light.
- Make sure the plants have enough water and nutrients.
- Before you begin any further training, allow 1-2 weeks for your body to recover.
What Happens After Topping
- In a "V"-shaped plant, two new colas grow.
- You can continue to top colas over time. Just don't go crazy.
- Combining the top with low-stress training (LST), or screen of green (SCROG), can maximize the yield.
Troubleshooting and Common Mistakes
- Cutting too soon - If you cut the plant before four nodes, it can stunt growth.
- Topping During Flowering - Causes stress and reduces the production of buds.
- Dirty Tools - Increases infection risk and causes a slower recovery.
- Too much topping - Stresses out the plant, which delays harvest.
The Role of Premium Cannabis Products in Successful Growing
When learning new techniques such as topping, it's important not to forget that healthy plants and quality genetics go hand in hand. Growers who combine their skills with quality cannabis products and start with strong varieties are more likely to achieve higher productivity and a richer taste profile.
Conclusion
The technique of topping is proven to increase yields, improve plant structure and control height. Timing is everything: Always top your cannabis plants during the vegetative phase, ideally when 4-6 nodes are developed. Clean tools, precise cuts, and good aftercare will result in larger, better harvests.
