In my experience, if done correctly, plants show no signs of slowing growth. They actually grow faster better because your exposing valuable growing tips(colas) to more light, stimulating growth. It doesnt take a rocket scientist to realize that shaded branches stop growing and eventually die off. Trimming or tucking the shading leaves stimulates bottom bud growth.

-If its your first grow....dont touch the leaves.
- If its your 4th grow and your tired of the god damn scraggly piece of shit buds on the bottom, either cut them off or remove some fan leaves and get more sun down there. Not having the sun moving across the sky is a burden us indoor growers have to bear.
drudown11 Reviewed by drudown11 on . Trimming 3-4 weeks into flowering? Hey everyone, I was going to post this in "Plant Problems" but everyone over there has spider-mites, and I didn't want to catch them. I've got two pre-98s and one lav just over three weeks into flowering. The sepals (to a lesser extent) and the adjacent fan leaves (to a greater extent) are blocking the light to the tops of each branch. Would it be ok to cut these back a little bit like I would for a newly cut clone? Can I do more, less? Any suggestions would be appreciated. Rating: 5
