The author was strwdog. That is an old report. BUT I DID NOT WRITE IT. I'm going to have the mods let me add that so it is clear.
I will say by following that report my female ratio went way up. but.....
I've been reading a lot and maybe the practices of pulling males in the "whole picture" of cannabis, and making "fem'd seeds" may not be good. As Hick has pounded in my head, I fully understand now. Males are just as important as the female esp. when isolating traits and creating crosses. So if you find a great late flowering male. think twice before yanking it. You may have a pheno that is worth keeping (and may never be seen just like that again). and whats it hurt to do a cross. its free seeds.
edit: Another way to look at it is...for every great male pheno that is destroyed the traits for the plant may be lost as well. I have heard of some still kicking themselves for years after for not keeping that particular female and male to make a cross they "beleived" coulda been a great cross of those two particular phenos. but only new after the seed was grown flowered to sens. and cured and smoked. They'll never know what coulda been.
