i get a roll of string from wal mart for like a buck its non fray shit so it doesnt get all up in the buds... i just tie a fairly lose granie knot in between one of the lower stacks on the particular branch and take the string back up thru the exhaust falange on my hood (dont have the glass on it due to the cool weather) and tie it up... anything i run with og in it seems like i have to do it with cuz they strech like a bitch after you flip em
