The practice of defoliating cannabis plants by strategically removing larger, sun-blocking foliage during the bloom phase aims to improve light penetration to lower bud sites. This technique focuses on the timing of this foliage removal to optimize plant energy distribution and maximize yield potential.
Judicious defoliation can result in increased airflow within the plant canopy, reducing the risk of mold and disease. By allowing more light to reach developing buds, this method supports improved bud development and potentially enhances cannabinoid production. The effectiveness of this technique is subject to debate, with varying opinions and observed results depending on strain, growing environment, and cultivation practices.
