ya i just did the two days of dark at the end of my PC and it made a great difference......the whole 5th week thing he said is supposed to make new bud growth out the sides of the buds to help add more weight and yield to the end product...he swared up and down that hes done it for a long time and has never had one turn hermaph yet, so i dont know if the plant is already past the point of turning hermaph after the 5th week or what...i wish there were more people that have done this cause it sounded like a solid idea, cause im always lookin for little ways to make my yield a little bigger any way i can, but im like yall i dont want to mess with nature unless i know it will work...thanx for the input so far yall!!
