Cutting fan leaves IS wrong.. i concur..
but...but...
for example,
if you have 12+ plants in a 4x4 area with a 1000watt hps
and you flower at 20 inches tall
You can/should remove more than just fan leaves from the bottom 6 inches of those plants, Including all dying or dead matter (fan leaves included) needs to be removed... this will help with light, AIR FLOW, and alllow the plant to use its strength in areas that will actual grow substanial buds.. : )

love

blue hue - great observation, great point,
you have taken on a MONUMENTAL and nobel task of pointing out misinformation... the world is FULL of it, if you continue to be "suprised" you will have some sort of mental break down.... I welcome your re-direction and guidance..

and watch out you dont give misinformmation about misinformation, cause we have a LIBRARIAN/SECURITY asshole ripper, among us, and he'd love to de-virginize you.

i love you
