Flip to 12/12 with transition period or not?

[Indoornesian]

My .02 cents, I stopped going by days breeders say as well as my own journals years ago. Here’s my reasoning, when your seasons change so does your environment. I’ve seen clones finish at different times than what the mother plant finished. Also different feeding regimens can prolong your finish date. To summarize, view trichs for a very definitive chop date. Once I see some senescence, I start checking and planning for the chop. My fingers stay sticky from this method.
