I really appreciate the info! That's exactly why I asked it here on this forum!Hi @WildBill
I know there are different strains that flower under 18 hour of light the Afghan auto and Iranian auto are two of them they can veg under 24/0 or 20/4 hours of light but started to flower under 18 or less hours of light. The same I have seen in a landrace from Papua New Guinea. In the batch of seeds I tested years ago was also some phenos that started to flower under 24 hours light.
We checked at all three strains the roots to see if a root bound was the trigger but it was definitely not.
I know some people who use the three strains to speed up the photoperiod strains in the cross.
I haven't done more experiments ( I wanted to make different crosses) because Ist my seed stock to the cops .
Some of my friends offered me to send me some fresh seeds but my focus was on other projects right now. Maybe I start next year with some new research and development on the auto side.
I hope it helps you a bit and if you need some more Infos feel free to ask me.
Ps. I also talked with Sasha the Joint doctor about the three strains and he have the same experience like I have. He also told me there are some Indian landraces who act like the three I have tested.
I wish you a nice day

I can understand how that could come about through nature in Papua New Guinea, but the Afghan doesn't make any sense to me.
This plant is always a source of amazement!
The only continent this plant is not native is naturally, Antarctica. And depending on when cannabis sativa evolved, It could have been there at one time, also.
OK I just had to find out so I asked:When did Cannabis Sativa evolve?
The consensus is 60 million years ago.
When did Antarctica first freeze over ?
The consensus is 34 million years ago.
There you go!
