I think there is value in it for sure, but where and how depends on the individual plants and their ancestral history.
For example, I think one would observe more varied results in landrace style varieties with a variable sunrise and sunset approach than with a plant from a seedline that has been bred indoors under 12/12 across many generations.
Also interesting to me is the effect of light spectrum and intensity changing over the course of a season, subtly. The same way day length changes slowly and subtlety over the course of a season so does it’s spectrum and intensity. I think they all contribute to the nuances within expressions in cannabis plants.
Would love to have access to data sensors in traditional cannabis cultivation regions that measure things like this, so they could be mimicked indoors as best possible. Much love
