the only plant material you should be trimming from the plant is the stuff that is dying. the plant will divert energy to the unhealthy leaves/stalks robbing energy from your buds so its best to trim those. the energy soaked up by the fan leaves will get used up at the damaged site instead of growing larger buds. but after so long the plant will give up on the damaged leaves and cut off all energy. trimming just speeds the process.
also, more powerful lights give you bigger buds because more energy is being offered to the plant. the fan leaves are able to absorb much more energy from a bigger light allowing the plant to grow bigger buds.
the people who trim healthy fan leaves forget about 1 very important thing...EVOLUTION. the plant has evolved over thousands of years into what we see today and fan leaves are an important part of the puzzle.
