I find your lighting schedule interisting and hope to incorporat what you have learned/seen. I have chosen my light cycles and flip method and will modify it as I see fit. I see it possible that changing day length (e.g. from 24 hrs, to 20 hrs) could very much be usefull. 25 years ago my technique evolved from using the old mechanical timers, I have never (until now) gone direct to flower, I would just gradually shorten day cycles/lengthen night over 14-30 days. Now I am using an arduino, I am not limited to a 24hr day and have basically limitless options for light timing. I currently run 17/7 in veg and 11/13 in flower (I like prime numbers), I don't believe I have ever seen this thing referred to as "stretch", until recently when I found it necessary to make some space and since I belive my techniqe takes longer, I flipped directly to 12/12 then to 11/12 over a couple of days. Previous experience with this strain with a gradual change did not exhibit this, I chose my method 25 years ago bc there is no place on earth where there would be such a dramatic change in lighting schedule. Stretch may have benifits I am unaware of (like bud structure?), but I prefer stalkier plants, they fit my style well.
I can appreciate your use of a different timing scheme, I think shorter cycles for both day and night is certainly worth the effort of investigating.
