Allright, I spent all night searching through years worth of subscriptions because I knew I had read about this somewhere before. This is what I found, it's an excerpt from Cannabis Culture #41 2003 by Dj Short.
" Once sexed, the process of elimination may begin. All of the females are kept and regularly examined to prevent unwanted hermaphroditism. Unwanted males and all hermaphrodites must be eliminated before they shed pollen-usually by the third week in the flowering cycle. The female plants need to checked for hermaphroditism until harvests.
(A quick word on backward hermaphrodites- declared males that eventually sport female flowers- as opposed to the usual female to male hermaphrodites. Theses are semi-rare occurances, usually sterile but sometimes viable, that I have found at times to be valuable in there genetic contributions. Some of the most resinous and desirable males I have encountered exhibited this trait. This trait almost seems to guarantee against unwanted hermaphroditism in subsecquent generations as it also increases the female to male ratio in its progeny.)"
If this is the case does anyone have any idea what strains he bred with this technique? It makes me wonder because all you ever heard was "kill the hermie" when the subject came up, but then someone developed feminized seeds. If there is a use for a regular hermaphrodite why not a backward one?
