Personally i never found a difference between harvesting in the light or the dark....my point of view on this is" If complete darkness is what you need to improve your smoke, you should concentrate on the whole process of growing better where a darkness period at the end doesnt make a difference in quality"

i cant say i never tried a dark period before harvesting..Weve all followed newbie urban myths at one point in our grows but...i just cant tell if there was an improvement or not! i dont think so!
