This is a much discussed topic, Im no expert but some of the comments amuse me like:
"I cut off fan leaves to give more light to bud leaves" - Scientifically speaking, do bud leafs produce more food for the bud or does the food from those leafs directly go to the bud? Of course it "seems" to make sense to people doing it, but is it "Scientifically" proven? What are the advantages of bud leafs over fan leafs? Does anyone know the facts that actually does cut off fan leafs?
"I suppose it comes down to what is best for each individual grower" - not really, there has to be either a right way or wrong way based on how the plant scientifically works. If you understand exactly how the plant works and what it needs then you will have the correct answer as to wether removing fan leafs or not is correct.
Dont get me wrong, I'm no expert, but logic has got to dictate this debate, there has to be a scientific answer, not just "it works for me" or " it doesnt work for me".
My thoughts on it are (only thoughts, not fact) - the plant is a whole connected system, why would you chop one type of leaf to get more light to another type of leaf if they both do the same job? You are effectivly reducing food production for the plant by a percentage and If the fan leafs do stop producing food in flower, then you are reducing a percentage of "stored" food for the plant. It really doesnt make sense to me to cut off leafs when they are part of the whole plant system that it has spent time and energy and food creating.
Of course it may be the fact that it has no negative impact, but we cant base this on just other peoples grows, what are the scientific facts?
Sorry if it seems like a bit of a rant, just seen a lot of threads/posts on this issue when there has to be a logical/scientific answer to this theory, instead of just "guessing".
Dont get me wrong, I havent done any proper research on it myself, I do plan on doing it at some stage, just working out other small kinks in my setup as I go along and will then concentrate on other methods, as its not a big issue at the moment.
