Absolutely not...........what will removing energy making, plant life sustaining leaves achieve?
How will the plants benefit from having their energy makers removed??
Just remember........less leaves = less energy being made = less potential..........it is that simple.
"Defoliation" is NOT a required "technique" when growing cannabis.
I would suggest only ever removing leaves that have gone yellow.
If the plants would not NEED those leaves, they would not grow them in the first place!
