Dark won't cause it to grow new trichomes (some call it resin). If it did you should leave the lights off for a few weeks to get the most bang for your buck http://www.youtube.com/watch?v=eW4tY8mQ_1o]http://www.youtube.com/watch?v=eW4tY8mQ_1o
Well that certainly answers why you suggest to chop just before lights on. Lol. I do recall an old grower claiming that she chopped late into "night" because she felt it helped flavor, so ill just go with that like I said...dark, drowning, other stress...does anyone actually know? Several weeks in the dark....well its a good thing we didn't delve into the realm of the ridiculous right? Whoops. Since six or seven hours of sleep a night is good why not take a 5 year nap while were at it? Hyperbole is fun. Thanks for the input though...
i dont know if this was said but a dark period will also help turn some of those trichs amber speeding up maturation because it thinks its dying.
