I do all my finishing outdoors so I trim the heck out of the leaves on my indica strains to let the light in. Almost as much on most of the sativa strains too. If I am thorough I will usually see a burst of growth in height soon after. Strategically removing leaves that are shading lower tops is definitely recommended.

My outdoor plants are all surrounded by leaves that I continually pick off. My back is still recovering from all the leaf picking I did this summer. On my outdoor plants I also remove the smaller buds and limbs that are not going to be worth the work later on. This really helps the big buds get bigger and harder.

I really like Pineapple and Blue Dream because the leaves are thin and don't need to be trimmed to let any light in.
