Sure but as a grower that’s one of the most important details for planning an outdoor or greenhouse crop. But it’s still all relative. A lot of grain crops are early or auto flowering northern varieties and if your goal is to harvest stem fibers then maybe a longer flowering sativa may be a better choice. To me if the plant produces cbd or thc it’s like the difference in a yellow or black lab. Not the most important detail or something that’s relatively easy to work one way or another.
I have a few other theories that may relate to it and the sexual nature of the plants but that’s another conversation.
It’s hard to call something an indica or sativa nowadays with the genetic drift from the same dozen starting points. Say we take some skunk in my experience skunk dominant plants flower somewhere around a 14.5h day. There’s a couple other traits that pass down when making extracts that one could infer what cuts are skunks. What are diesels etc.
In my experience with “sativas” there’s a difference between a Mexican and Columbian and Thai with grown patterns and effects. By observing the phenotype/shapes of the plant and flowering times it’s easier to classify the dominance in some genes today.
