Interesting read I found here.
An Update on Plant Photobiology and Implications for Cannabis Production
Thanks! I do like the research papers when they are recent since they are now more specific about cannabis. If you like a more descriptive video sort of delivery - there are these videos at https://www.apogeeinstruments.com/videos-and-tutorials/
So the presenter is a guy ( shit you not - Dr. Bugbee ) who tends to pound in the concepts, he goes there about how terms seem mixed and confusing. I've noticed that at the ends of these videos - they have spliced in some extra minutes where he gets specific about spectrum effects with cannabis. Apparently they have a license to do cannabis research that makes this a bit better than the usual academic exercise of extrapolation to shit they really aren't sure about.
Dr. Bugbee does seem to have the appearance of being like, really smoked out. I like how he tends to explain the background history of the science involved.
