When it comes to growing cannabis, one of the most effective and easiest techniques for boosting your plant’s growth is topping. This simple yet powerful method allows your cannabis to grow bushier, yielding more buds while improving overall plant health.
Whether you’re a seasoned grower or just getting started, learning how to properly top your cannabis plants can make a significant difference in your harvest. Let’s dive into why topping works, when to do it, and how you can master the technique.
What Is Topping?
Topping refers to the process of cutting off the top part of the cannabis plant, which redirects its growth from a single main cola to multiple colas or branches. This technique helps the plant grow outward, creating a bushier structure and allowing light to penetrate deeper into the plant, resulting in healthier growth.
In nature, cannabis tends to grow in a tall, conical shape with one dominant cola at the top, but topping breaks this habit by promoting lateral growth. This way, your cannabis plant can develop more flowers and maximize the available space.
While topping might seem like a simple pruning method, it has profound effects on how your plant grows and develops, especially in indoor settings where light exposure is limited to the top of the plant. By topping, you ensure that the energy the plant would have spent growing upwards is instead distributed across multiple growing tips, leading to bigger and more resin-packed buds.
After topping, the trimmed cannabis refers to the leaves, small branches, and other parts of the plant that are cut off. While these trimmed parts may seem like waste, they can still have value. Many growers use trimmed cannabis to make concentrates, edibles, or extracts.
The trimmed leaves often contain valuable cannabinoids and terpenes that can be utilized in various ways. Moreover, removing these parts helps improve airflow and light distribution to the healthier parts of the plant, contributing to a more productive and robust harvest. So, the trimmed cannabis from the topping process shouldn’t be discarded – it can still play an essential role in the overall cannabis cultivation process.
Why Top a Cannabis Plant?
Cannabis naturally grows in a way that prioritizes a single, dominant cola at the top of the plant, while lower branches often struggle to catch up. These lower branches tend to receive less light and, consequently, produce smaller, less potent buds. Topping addresses this by promoting lateral growth, ensuring that the lower branches receive more light and energy, resulting in more buds and higher yields.
Here’s why topping works so well:
- Boosts Yields: By cutting off the top of the plant, you create multiple growth points, allowing more buds to form. This usually leads to a significant increase in overall yield, with some growers reporting up to 30% more flowers.
- Better Light Penetration: Topping creates an even canopy, allowing light to reach the lower branches that would otherwise be shaded. More light means more energy for the plant to produce buds.
- Improved Airflow: The more open structure created by topping helps maintain proper airflow, reducing the risk of mold and mildew, and ensuring the plant remains healthy throughout its growth cycle.
Potential Benefits of Topping
Topping isn’t just about increasing your cannabis plant’s size; it also contributes to better plant health and more efficient use of light. Here’s a quick rundown of the key benefits:
- Increased Flower Sites: By promoting more side branches, topping creates additional sites for buds to form, ultimately leading to a bigger harvest.
- More Even Canopy: Topping evens out the plant’s growth, which helps improve light distribution and reduces the risk of leggy, underdeveloped growth at the plant’s base.
- Stronger Plants: When you top the plant, the resulting structure is often more resilient and better able to support larger buds. This also reduces the chances of branches breaking under the weight of heavy flowers.
Potential Drawbacks of Topping
While topping can greatly benefit your plants, it’s not without its risks if not done properly. Here are a few potential downsides to consider:
- Growth Slowdown: After topping, the plant may take a few days or even weeks to recover and resume growing. During this period, you might notice slower growth, but this is temporary and should not have a long-term impact on your yield.
- Plant Stress: Like any type of pruning, topping can stress the plant, especially if done too aggressively or at the wrong time. It’s important to allow the plant to recover fully between top operations.
- Improper Cuts: If you top too early or too late in the plant’s growth cycle, it could lead to stunted growth or even damage the plant. Ensuring you have the right timing and technique is crucial for success.
When to Top Cannabis Plants?
The best time to top your cannabis plants is during the vegetative stage, typically 3 to 6 weeks after germination. This is when the plant is still in its early growth phase, actively building its stem and leaves.
Topping too early, when the plant is still small and fragile, can stunt its growth. On the other hand, topping too late, especially once the plant has begun flowering, can interfere with its ability to focus on bud production and ultimately reduce your yield.
It’s also important to ensure that the plant is in good health before topping. If the plant is stressed or weak, it may not handle the shock of topping very well.
How to Top Cannabis Plants
Topping cannabis plants is a relatively simple process, but it requires precision. Here’s a step-by-step guide to doing it right:
- Prepare Your Tools: Start with clean, sharp scissors or pruning shears to avoid damaging the plant and to reduce the risk of infection. Disinfect your tools with alcohol before making any cuts.
- Locate the Top Node: Find the top node of the plant (where the leaves and branches meet). This is where you will make your cut.
- Make the Cut: Cut just above the top node, leaving enough room for two new growth points to emerge. Be sure to make a clean cut to prevent stress and disease.
- Remove Lower Branches: After topping, remove any lower branches that won’t receive adequate light. This helps direct energy toward the top of the plant, where the best buds will form.
- Monitor the Plant’s Recovery: After topping, your plant may experience a brief period of stress. Make sure it’s in optimal growing conditions, with plenty of light, water, and nutrients to help it recover quickly.
Common Topping Mistakes to Avoid
To ensure you get the best results, avoid these common mistakes when topping cannabis plants:
- Topping Too Early: Topping a plant before it has enough nodes or leaves can stunt its growth. Wait until the plant is strong and healthy.
- Topping During Flowering: This is a big no-no. Topping during the flowering phase can harm your yield by disrupting the plant’s focus on producing buds.
- Improper Cuts: Always make clean, sharp cuts. Dull tools can damage the plant and create entry points for infections.
- Neglecting Recovery: After topping, give your plant time to recover before stressing it further. Proper care and nutrients will ensure healthy regrowth.
Conclusion
Topping is an effective and straightforward technique that can significantly improve your cannabis harvest. By promoting lateral growth and better light distribution, you can achieve higher yields and healthier plants. Just make sure to follow the right timing and methods for best results, and avoid common mistakes that can harm your plants.
