Every successful crop I've ever had was the result of removing the fan/shade leaves.
I began doing so based on an article by "R" in High Times around 1980.
It was titled Pruning for Production.
Has always worked for me. Longer buds and more of them compared to plants whose shade leaves are not removed.

Didn't "R" turn out to be Ed Rosenthal?

Grow 'em however you please. Grow more than you need and give away the surplus for free.:thumbsup:
