Tucking fan leaves in cannabis cultivation is a technique used to optimize light distribution and penetration within the canopy. While it may seem counterintuitive at first, tucking or removing some fan leaves can be beneficial for several reasons:
Light Distribution: By tucking or removing fan leaves that are shading bud sites, you can ensure that more light reaches the lower parts of the plant where the potential bud sites are. This can help improve the overall yield and quality of your harvest.
Air Circulation: Tucking leaves can also improve airflow within the canopy, reducing the risk of mold and mildew development, as well as promoting better overall plant health.
Energy Allocation: Cannabis plants do require light for photosynthesis, which takes place primarily in the leaves. However, once energy is produced through photosynthesis, it is transported to different parts of the plant, including the flowers (buds). Tucking leaves doesn't stop the photosynthesis process; it redirects the energy flow to the areas that need it most, which are the developing buds.
Pruning Strategy: Tucking fan leaves is often part of a broader pruning strategy that also includes selectively removing some leaves to improve light and airflow. This can help optimize the balance between energy production in the leaves and energy allocation to the buds.
In summary, tucking fan leaves can help ensure that both leaves and bud sites receive an appropriate amount of light and energy. It's about creating a balance that maximizes the overall health and yield of your cannabis plants. However, it's essential to be mindful of not overpruning or removing too many leaves, as this can stress the plant. The specific approach may also depend on the strain and individual plant's needs, so it's a good practice to monitor your plants and adjust your techniques as necessary during the different growth stages.
