修剪是有意去除植物的某些部分——叶子、嫩枝、茎或花朵——以引导植物的能量，改善空气流通，控制植物的大小，并提高产量质量。在室内和水培种植中，修剪技术包括脱叶（去除叶子）、摘心（剪掉主生长点以产生多个可乐芽），以及棒棒糖法（去除下部生长，将能量集中在上层树冠部位）。
关键事实
- Defoliation: removes large fan leaves blocking light from lower bud sites or increasing humidity
- Topping: cuts the apical (main) shoot to produce two main branches — increases width and yield sites
- FIMing (F*** I Missed): a partial top that produces 4 new shoots from one cut point
- Lollipopping: strips lower growth to improve airflow and concentrate energy on the top canopy
- Pruning timing matters — avoid heavy pruning within 2 weeks of harvest
- Always use clean, sharp tools to prevent introducing pathogens at cut sites
