The Pros and Cons of Advanced Cannabis Pruning Techniques: Achieving Better Growth and Yield

Updated: May 16

Pruning is a vital aspect of cannabis cultivation, particularly during the cloning stage, as it sets the foundation for robust growth and maximum yields. In this introductory guide, we'll explore effective pruning techniques, and the pros and cons of each, specifically tailored to enhance the growth and yield of cannabis clones.

Topping: Encouraging Bushier Growth

Topping involves removing the apical meristem (topmost growth tip) of the plant, encouraging lateral growth and creating a bushier structure. By topping cannabis clones, growers can control height, promote even canopy development, and increase the number of flowering sites, ultimately leading to higher yields.


  • Encourages bushier growth: Promotes lateral branching, resulting in a fuller canopy.

  • Increases flowering sites: Enhances yield potential by creating more colas.

  • Controls height: Helps maintain an even canopy and prevents plants from growing too tall.


  • Can cause stress: Improper topping can shock the plant and slow down growth temporarily.

  • Requires timing: Topping should be done during the vegetative stage and requires careful consideration of plant health.

FIMing (F*ck, I Missed): Maximizing Branching

FIMing is a variation of topping where only a portion of the apical meristem is removed, leaving behind a small cluster of new growth tips. This technique promotes multiple branching, resulting in a denser and more productive canopy. FIMing is preferred by some growers for its ability to encourage lateral growth while minimizing stress on the plant.


  • Stimulates branching: Encourages multiple new growth tips without removing the entire apical meristem.

  • Less stressful than topping: FIMing typically results in less stress for the plant compared to traditional topping.

  • Increases yield potential: Similar to topping, FIMing can enhance yield by creating more flowering sites.


  • Requires precision: FIMing requires careful execution to achieve the desired results without damaging the plant.

  • May not be as effective as topping: Some growers find that FIMing doesn't produce as consistent results as topping.

Lollipopping: Cleaning Up the Lower Growth

Lollipopping involves removing the lower branches and foliage that receive minimal light exposure. By redirecting the plant's energy towards upper growth and flowering sites, lollipopping helps improve air circulation, reduce the risk of mold and pests, and focus resources on producing larger, more potent buds.


  • Improves airflow: Removing lower foliage reduces humidity and improves air circulation within the canopy.

  • Prevents mold and pest problems: Eliminates shaded areas where pests and mold are more likely to thrive.

  • Focuses energy on top growth: Redirects resources to upper branches and flowering sites, maximizing yield potential.


  • Can stress the plant: Removing too much foliage at once can stress the plant, affecting overall health and growth.

  • Risk of over-pruning: Care must be taken not to remove too many leaves, which can hinder photosynthesis.

Defoliation: Enhancing Light Penetration

Defoliation entails selectively removing large fan leaves to allow better light penetration and airflow within the canopy. This technique is particularly beneficial during the flowering stage but can also be applied to clones to encourage more efficient light utilization, leading to increased photosynthesis and ultimately higher yields.


  • Increases light penetration: Removing large fan leaves allows more light to reach lower branches and flowering sites.

  • Improves airflow: Reduces humidity and prevents mold by opening up the canopy.

  • Enhances bud development: Allows more energy to be directed towards bud production, resulting in larger, denser buds.


  • Can slow growth temporarily: Removing too many leaves at once can stress the plant and slow down growth.

  • Requires careful timing: Defoliation is best done during the vegetative stage or early flowering stage to minimize stress.

Supercropping: Strengthening Branch Structure

Supercropping involves gently bending and manipulating the branches to stress the plant, promoting the formation of thicker and stronger stems. By supercropping cannabis clones, growers can create a more robust plant structure capable of supporting heavier yields without the need for additional support. Additionally, supercropping can improve nutrient distribution and airflow within the canopy.


  • Strengthens stems: Bending and manipulating branches promotes thicker, sturdier stems.

  • Increases light exposure: Allows more light to reach lower branches and flowering sites, maximizing yield potential.

  • Improves nutrient distribution: Stimulates sap flow, ensuring nutrients are evenly distributed throughout the plant.


  • Risk of injury: Supercropping can cause damage if not done carefully, potentially leading to infection or reduced growth.

  • Requires recovery time: Plants may need time to recover from the stress of supercropping, temporarily slowing down growth.

LST (Low-Stress Training): Controlling Canopy Height

LST is a gentle training technique that involves tying down the branches to create a more horizontal canopy. By manipulating the plant's growth trajectory, LST allows for more even light distribution, encourages lateral growth, and prevents the plant from becoming too tall, making it easier to manage in limited vertical spaces.


  • Controls height: Allows growers to keep plants short and bushy, maximizing light exposure to all parts of the canopy.

  • Encourages even growth: Creates a more uniform canopy, resulting in more consistent yields.

  • Reduces risk of mold: Opens up the canopy, improving airflow and reducing humidity levels.


  • Requires regular maintenance: Plants need to be trained regularly to maintain the desired shape and structure.

  • Can be time-consuming: LST involves tying down branches and may require more time and effort compared to other pruning techniques.

Monster Cropping: Maximizing Branching and Flowering

Monster cropping involves taking clones from plants during the flowering stage, resulting in unique growth patterns characterized by increased branching and flowering sites. While unconventional, monster cropping can yield impressive results, with plants exhibiting vigorous growth and producing abundant harvests.


  • Increases branching: Clones taken from flowering plants tend to produce more branches and flowering sites.

  • Creates unique growth patterns: Monster-cropped plants often exhibit unusual growth patterns, which can be visually appealing.

  • Potentially higher yields: More branches and flowering sites can result in higher yields compared to traditional clones.


  • Longer vegetative period: Monster-cropped plants may take longer to revert to the vegetative stage and resume normal growth.

  • Risk of stress: Taking clones from flowering plants can stress the mother plant and reduce overall yield.

Selective Pruning: Targeted Removal of Unwanted Growth

Selective pruning involves identifying and removing specific growth nodes, shoots, or branches that hinder overall plant development or airflow. By strategically pruning clones to eliminate crowded or weak growth, growers can redirect resources towards more productive areas, promoting healthier and more vigorous plants.


  • Removes weak or unwanted growth: Improves airflow and light penetration by eliminating crowded or shaded areas.

  • Encourages more vigorous growth: Redirects energy to healthy, productive branches, maximizing yield potential.

  • Customizable: Allows growers to tailor pruning to the specific needs of each plant, promoting optimal growth and development.


  • Requires careful consideration: Each cut should be made thoughtfully to avoid damaging the plant or hindering growth.

  • Risk of over-pruning: Removing too much foliage or too many branches can stress the plant and reduce yield potential.

Effective pruning is a cornerstone of successful cannabis cultivation, particularly during the cloning stage, where every decision impacts the plant's future growth and yield potential. By mastering pruning techniques such as topping, FIMing, lollipopping, and defoliation, growers can sculpt their cannabis plants into thriving and productive specimens capable of producing abundant harvests.

Experiment with different pruning methods, observe how your plants respond, and tailor your approach to suit the specific needs of your cannabis strains and cultivation environment. With patience, practice, and a keen understanding of plant physiology, you'll unlock the full potential of your cannabis clones and reap the rewards come harvest time.
