Aloha fellow travelers!
I have some additional thoughts that began in thread #206-
My understanding is that late in veg, several weeks before calyx development; this is the time that is most critical with regards to plants expressing sex. If there is stress during this time, the probability of expression of males and hermaphrodites increases. Forcing plants with light change coupled with high temperatures before they are mature in their expression may alter sex from potential females to males.
(As an aside, my last germination yielded 2/9 females. Come to find out I did not change my bulbs after my last grow and started with both HPS instead of the Blue light I typically start with. Humidity was low also. More males (7). Hmmm.)
Back to topic- if there are other stressors during this time, then fewer females will express. As I recall, this information as well as earlier information I shared came from Dutch Passion circa late 90’s as a disclaimer to their Feminized Seeds which were originally sold as Female Seeds until hermaphrodites and males starting showing up in their seed lots which were originally sold as “Female Seeds.”
My thinking is that if you now take a plant that has epigenetically adapted to its environment for many years and either self it or radically change its environment, i.e. stress it, one may get the sensitivity that may be occurring as mentioned in the G13/Widow thread. This is just a guess as I am a grower of Cannabis, but I am no expert on this subject. What I do know is that Cannabis is highly adaptable and that the plant itself has survived many of my mistakes over the years.
Feel free, experts, to chime in.
