@Mossy no led here..no way no how..
I trim leaves for...
1. Bud sites more light
2. More air flow through plant
3. Keeps the plant in a state of stress
4. Plant works harder with less leaves keeps the nutrients flowing and used up..they use their energy instead of storing sugars and and getting backed up with excess nitrogen
5. Total less leaves in grow space allows more plants to be grown due to space allowance
6. When I harvest ALL my trimming go into butter bag..all stemed leaves are gone and what's left is tricome incrusted sugar leaves...makes trimming a breeze
7. No humidity sweats with less leaves
8. I love a gnarly looking plants
9. Overall less humidity in grow tent
10. I like buds with stems in them..not stems with buds on them
Plants use sign language for communication...you just have to pay attention and read them... weed plants just want to make flowers..that's it...that's their whole purpose in life...ditch the leaves..grow the buds
