Extended darkness before harvest

Hi everyone,

I've heard that keeping plants in the dark for a while before harvest increases potency or changes the cannabinoid profile favorably. I remember reading this from an article by either DJ Short or Dr. Atomic. Does anyone have any first hand experience with this? What is the optimal length of the final dark period before chop?

There are like 10 other posts that ask the exact same question in the last week. pls use SEARCH .......JR

but most do use 24-48 hrs of dark..

They say 36 hrs.
I have tryed with many strains. Put one in dark and harvest other (same strains) and to me I just found it a waste of time. But one must find out if it works for them or, first hand.

Bog recomends doing this but I think its bullshit,I tried that darkness for 72 hours before flowering and it about killed my ladies.Arjan recommends that bullshit,the sunlight dont stop shineing and its just not natural for any extended dark period......................peace
