Growing your own cannabis can be a rewarding experience, but it’s essential to understand techniques that can help your plants thrive.
One such method is ‘topping.’ Topping your weed plants isn’t as mysterious as it sounds; it’s a way to encourage healthier and bushier growth.
In this article, we’ll walk you through the basics of topping, why it’s beneficial, and how to do it the right way.
Whether you’re a seasoned cultivator or just getting started, we’ve got you covered. Let’s dive into the world of topping and give your cannabis plants a boost.
What Does ‘Topping’ Mean in Weed Plant Cultivation?
When learning how to grow cannabis plants, you might have already come across the word “topping.” In weed plant cultivation, “topping” is a pruning technique used to control the plant’s growth and promote bushier, more compact growth.
It involves cutting off the main, or apical, growth tip of the cannabis plant, which encourages the growth of multiple lateral branches.
This technique is employed to enhance light distribution, increase the number of bud sites, and improve overall yields during the flowering stage.
Topping is just one of several training methods used by growers to optimize the growth and development of cannabis plants.
Topping vs. Fimming: What Is the Difference?
Topping and Fimming are two common pruning techniques used in cannabis cultivation, and while they share similarities, they have distinct differences:
Topping involves cutting off the main apical bud or growth tip of the cannabis plant. This results in the development of two main colas or branches below the cut.
Topping encourages the plant to become bushier and can create a more even canopy.
Fimming also involves trimming the apical growth tip, but it’s done in a less precise and deliberate manner.
Instead of cleanly cutting, Fimming usually involves pinching or partially cutting the tip, leaving a cluster of new growth points. Fimming often results in the growth of multiple smaller shoots rather than just two main colas.
The primary difference between the two techniques is the degree of pruning and the resulting growth pattern.
Topping typically results in two distinct main branches, while Fimming encourages a more chaotic growth pattern with multiple shoots. Growers may choose one technique over the other based on their specific goals for plant structure and yield.
When to Top Cannabis Plants
Topping cannabis plants is typically done during the vegetative stage, when the plant is actively growing but hasn’t yet begun flowering.
The ideal time to top your cannabis plants is usually when they have developed a few sets of leaves, typically around the 4th to 6th set of nodes.
Here’s a step-by-step guide for when to top:
- Wait for Multiple Nodes: Allow your cannabis plant to grow until it has at least 4 to 6 sets of nodes (pairs of leaves).
- Choose the Right Node: Identify the node just below the newest growth tip. This is where you will make your cut.
- Make the Cut: Using clean and sharp scissors or pruning shears, snip off the top growth tip just above the chosen node.
- Monitor Growth: After topping, your plant will develop two main colas from the nodes just below the cut. Keep an eye on its growth to ensure the new branches develop well.
Topping during the vegetative stage encourages the plant to grow into a bushier shape, which can lead to increased yields and a more even canopy when it enters the flowering stage.
Remember that each strain and plant may respond slightly differently, so it’s a good practice to start with just one or two plants to gain experience before topping all of your cannabis plants.
Benefits of Topping Weed Plants
Topping weed plants offers several benefits for cannabis cultivation:
Improved Canopy Control
Topping helps maintain an even and manageable canopy by promoting lateral growth. This prevents the plant from becoming too tall and encourages a more bushy shape.
Enhanced Light Penetration
By creating multiple main colas, topping ensures that more parts of the plant receive direct light. This maximizes photosynthesis and promotes healthy growth throughout the plant.
Increased Bud Sites
Topping encourages the development of additional bud sites, leading to more potential flower production. This can result in higher yields of quality cannabis.
Enhanced Yield Potential
With more bud sites and even light distribution, topped plants have the potential for increased yields, making it a preferred technique for many growers.
Better Air Circulation
A bushier, well-topped plant allows for improved airflow around and within the canopy. This reduces the risk of mold and pest issues and promotes overall plant health. The resultant plant can be used for multiple cannabis-infused products like Delta 8 gummies, THC tinctures or Vapes.
By implementing topping, growers can optimize their cannabis plants’ structure and yield potential, ultimately leading to a successful and bountiful harvest.
Are There Any Potential Drawbacks of Topping Cannabis?
While topping cannabis plants can offer several benefits, there are potential drawbacks to consider:
- Stress: Topping causes stress to the plant, which can slow down growth temporarily. This stress can lead to a few days of recovery before the plant resumes vigorous growth.
- Slower Vegetative Growth: Topped plants may experience slower vegetative growth initially because the plant redirects energy to repair and develop new branches. This can extend the vegetative stage.
- Risk of Infection: Any time you make cuts on a plant, there’s a risk of introducing pathogens or pests. It’s crucial to use sterile tools and techniques to minimize this risk.
- Mistakes: Inexperienced growers might make mistakes when topping, such as cutting too low or damaging the plant. It’s important to be precise to avoid potential issues.
- Delayed Flowering: Topping can delay the flowering phase, as the plant needs additional time to recover and develop new growth before it starts producing flowers.
- Genetic Variability: Not all cannabis strains respond the same way to topping. Some strains may not develop as many branches or bud sites as desired. To avoid any potential problems, make sure to get high-quality strains from the best seed banks online that have a good track record.
These potential drawbacks highlight the importance of proper technique and timing when topping cannabis plants.
Growers should also be prepared for a brief period of slower growth and closely monitor their plants to ensure they recover and develop well.
Detailed Guide on How to Top Weed Plants
Here’s a detailed guide on how to top weed plants:
Selecting the Right Growth Stage
Topping is typically done during the vegetative stage, not during flowering. Wait until your cannabis plant has developed at least 4 to 6 sets of nodes (pairs of leaves) before topping.
Proper Pruning Tools
To top your cannabis plants, you will need a few essential tools:
- Sterilized scissors or pruning shears: Clean and sterilize your cutting tools to prevent introducing pathogens.
- Protective gear (optional): Gloves and eyewear can protect you from resin and plant sap.
Pruning Method Step-By-Step
- Prepare Your Workspace: Set up a clean and well-lit workspace. Ensure your tools are sterilized to prevent infections.
- Identify the Right Node: Look for the node just below the newest growth tip. This is the point where you’ll make your cut.
- Make the Cut: Carefully use your sterilized scissors or pruning shears to snip off the top growth tip, just above the selected node. Ensure a clean and precise cut to minimize stress on the plant.
- Monitor Growth: After topping, the plant will develop two new main colas from the nodes just below the cut. Monitor the new branches’ growth and overall plant health.
Provide your plant with proper care following topping:
- Maintain an optimal environment with adequate lighting, temperature, and humidity.
- Consider applying a mild nutrient solution if your plant shows signs of stress or deficiency.
