The reason you found out the sex and it works so greatwas because it was a sativa.Indicas and afgahns are not at all the same.They don't stretch near as bad or get as tall.therfore when you set lights as to sex them,your strain grew abit so as to better tell the sex.Smaller seedling have a tendency to knot up at the node and it's hard to tell the sex.For the novice,anyway.I know what time it is.
