Hey there!
When it comes to removing fan leaves from auto-flowering plants, it's a bit of a mixed bag. Some growers swear by defoliation to improve airflow and light penetration, while others prefer to let the plant's natural growth take its course. Here are a few things to consider:
Airflow and Light Penetration: If your canopy is overcrowded and the fan leaves are blocking light from reaching lower bud sites, or if airflow is restricted, removing some of the larger fan leaves may help improve both airflow and light penetration. This can potentially lead to better overall bud development and reduce the risk of mold or mildew.
Stress: However, it's essential to be cautious when defoliating auto-flowering plants, as they have a limited vegetative period and any stress during this time can impact their overall growth and yield. Removing too many leaves at once can shock the plant and slow down its growth.
Selective Defoliation: If you decide to remove fan leaves, it's best to do so selectively and gradually. Focus on removing only the largest, oldest leaves that are blocking light or airflow, leaving the smaller, newer leaves intact. This will minimize stress on the plant while still providing the benefits of defoliation.
Monitor Progress: Keep a close eye on your plant's response after defoliation. If you notice signs of stress such as wilting or yellowing leaves, it may be a sign that you've removed too much foliage. In that case, it's best to stop defoliating and allow the plant to recover.
Ultimately, whether or not to remove fan leaves from your auto-flowering plant is a matter of personal preference and depends on the specific needs of your grow space. If you're concerned about overcrowding and light penetration, selective defoliation may be worth considering, but be sure to proceed with caution to avoid stressing the plant unnecessarily.
