Is trimming fan leaves off buds OK or not?

whatever the truth is both sides will debate so long as no one does a scientific side-by-side comparing competent trimming vs not...
(like something analogous to that Kite guy with his UVB study)

my guess is all things being equal a plant with its foliage removed "Appears" to grow fast because its immediate response is to replace/re-grow its foliage to resume its growth cycle

still OTOH, I'd also bet there is some "crafted" method to strategically remove less efficient foliage, but my guess also is 1/2 of us that do it are just hacks...
studies have been done scientifically THEY SAY DONT TRIM THE FAN LEAVES!

thanks bro...and just out of genuine curiosity (and not as a challenge to what you say), you got any links? I'd like to read them (again, not questioning you at all, just thinking it would be a interesting read)

peace

  • Do not remove leaves indiscriminately.
  • Do not remove young leaves unless heavily damaged by bugs or molds.
  • Do not sacrifice healthy leaves near the light for the sake of lower leaves.
  • Remove leaves that are beginning to yellow.
  • Do not remove mature leaves if you have a weak root system.
  • Use light movers, oscillating fans, and reflective material to improve light penetration
  • Grow your plants short to keep all the branches as close to the lights source as possible
  • Use selective pruning to remove sucker shoots that use up valuable plant energy

Damn another one of these threads. There is one about 3 threads down from this one. Lots of good information in there as well.

guys. trim them leafs off once the buds are 1/4 inch thick you will get bigger yields. do your self a favor. do one plant and not the other see the difference. next time you will be trimming the leafs off .

When the plant gets to the point where it is blocking the light I will LST it by tipping it by the roots (while the hydroton/lava rock table is flooded) into a position most beneficial for all in the garden. If I have to tie it up, I'll tie it up using a small piece of thin cardboard so the string is insulated from the stalks.

Agreed with all the above; but only to a point as most of that is common sense for a SCroG grow....

this is: my curiosity/questions/doubts stems from removing perfectly good fan leaf: addition by subtraction so to speak
...I dunno, w/o further open minded reading; can't totally wrap my head around some of the defoliation thing...and again, thats recognizing there is like a gazillion heated defoliation debate threads posted already

Once again I prune all throughout the plants life and in all honesty I start from the top and trim one side then alternate. It evens out the canopy and brings the branches at the bottom to the top there is not an article on the whole web that is going to change 20 years of personal experience so I guess we agree to disagree. Don't do it when they are too young though cus it will stun the growth. I just know for whatever growth sacrificed by pruning (if any) there is 2x that spent on the growth and development of shaded branches that would have popcorn but now are colas for instance (don't mind the Nitrogen OD)
 
So as I said in post #17, I went ahead and trimmed, right. Well I just wanted to give a little update on what I've noticed in the change of the plants, what I'll call, attitude. First thing that I noticed after just one 12hr cycle of light is that the remaining leafs have perked up. The second is that the buds on lower branches, where the pistols were just kinda laying over are now stretched out. As if both leaves and flowers are reaching for the light. I think is a good thing...

This is an ancient question in Botany. You don't need to worry about ganja myths if you have all Botany at your call.

So, what are you trying to do? If you want max yield per plant, then you will double harvest. The later produced buds will be less mature, need a few more weeks.

Or if you are like me and trying to get a big, but not max yield every month, I can't afford to double harvest. I need the light, for the next set.

So, what are you trying to do? For me, I have been experimenting with just not allowing second branching. I began early and every few days, I simple pinch off any new branches from the dominate branches. I want those to be long, so I can gather them into a mesh or strings or tomato fence or whatever to hold up the buds.

That way, I never let the branch begin, and it is no stress. I never let the plant get used to something and then take it away.

So, I have less room and less time than outdoors, but, want a good leaf set in veg and no stress. (still got a bug in the picture adder)

Just pinch the secondaries, and I get a wide but open bush. But, it is because of what I want to do. I want all the produce to mature at about the same time. We will see.

nice plants im not saying that removing the leaves will kill your plant the plant will always try and compensate maybe even give you a growth spurt i would like to see what the THC/CBD % or those vs a plant with the fan leaves till then ill stick to DR Rosenthal. and i doupt itll double your harvest because then it would be common practice
