Removing fan leaves

Hey everyone, I'm just wondering what everyone else's take is on removing fan leaves. I generally remove them once I feel the side branch is big enough to catch enough light without the help of the bigger leaves, allowing lower branches to get some light as well. Side by side grows in my experience shows minimal difference in yield though.

I believe you should pull them off once they are at max size and are being shaded by the higher better lit leaves.

Defoliation helps the plant to direct energy to the new growth instead of maintaining older leaves.

And besides old leaves are targets for pests.

Yea once you have a couple bouts of pm, the borg or thrips you will be pulling off all the excess leaves that dont belong. 

You will find they photosythesise better with new healthy leaves, they focus all the growth auxins up the plant instead of maintaining that uncle that you gotta keep paying for.

I am not a fan of pulling fan leaves unless:

  1. They are damaged, yellowing
  2. They are infested with bugs, PM
  3. They are covering a flowering bud site in flowering
  4. They are impeding air flow
  5. They are far below the top fan leaf canopy 

All but 3 & 5 can be fixed with better environmental controls and pest management.

I'm not sure if understand the point of removing fan leaf just to create more leaf.

NO.3 is a big "NO"

You should not cut the leaves growing in the bud site, those leaves feed the bud.

@Oolong83  you contradicting yourself because the video you posted does not support your earlier post.

I'm with Jorge!

 

My earlier post was about defoliating, this is about cutting the leaves on the bud sites. 

i should've probably stated that earlier.

but yeah, Jorge knows his shit. his got a shitload of useful info.

Indoor I do remove (fix light).. Outdoor I don't (moving light).. or only if forced by a epidemic
