I have learned the trimming lesson the HARD WAY....
I have grown for 10+yrs (outdoor).
ok ill try another epic post..lol..

I found that when I clipped My Larger Shade leaves that its wasnt the bset idea..

when they go to flower the little peice of stem that goes to the Big Shadies is what the Larger Buds are supported on.
so If you snip em then the bud that forms at that junction will be NOWHERE as big or juicy if you had left it there because it cannot be supported.
so be carfull when snippin shade leaves only take the dead ones off.
