My 2 cents....
I just puffed a FAT kusher to my head, so bear with me.
I'm trippin on the "fan leaf" , "mini fan leaf" thing. IMO, true fan leaves are connected directly to the Main stems of the Plant. Sometimes they are on the main stalk, but leaves that are connected to individual stems are also "fan leaves" imo.
The "Mini leaves" are what is produced in some bud while flowering, NOT directly connected to the Main plant stalk itself. These have little value to tric OR bud development. They do aid in the plants overall health, thats for sure.
Hick has allready stated the facts
Hick said:
THE FAN LEAVES ARE WHERE THE BULK OF PHOTOSYNTHESIS TAKES PLACE.. NOT ON TINY .."SPEAR LEAVES" (NEW BOTANICAL TERM) OR ON STEMS, STALKS, OR FLOWERS.
When fan leaves are removed, the ability of the plant to metabolize is drastically reduced, eliminated. It "IS NOT" beneficial to the plant.
Photosynthesis being the KEY to the whole discussion here. The plants energy source. Without ample amounts ofsugars produced naturally thru photosysthesis, the plant will not produce to it's full potential.
So, with that said, cutting of any Major fan leaves is just not a good thing to do. Some of the best buds I've smoked are the ones hidden beneath the big fan leaves.
There is allways a flip side to the coin too. It is beneficial to trim up your plants and remove some leaves and branches. ALLWAYS start from the bottom and go up when pruning a plant.
You gotta figure a HID lights penetrating depth is somewhere around 4 feet. That is for a 1000w HID, not to sure about others, but I am sure it is easy to look up, google rox. So, for me, anything under that 3.5' to 4' "line" gets cut out. If a particular branch has a top the reaches the "line" but some of the branch does not, I will trim up that particular brach, not just cut the whole thing off.
So, moral of the story is, leave the leaves alone. That sounded cool huh?
