Have you ever heard of the 11/13? I can send you a link if you want. I’ve heard mixed reviews, originally I heard dj short speaking about it on a panel for high times, but there’s also something called the gas lantern method that’s similar or the same. I haven’t read much into that. The vest short explains it, is it helps the plants express phenotypic expression, cuts some time off flower potentially, and doesn’t effect yields. It’s also the natural flowering time near the equator, so it may be better for sativa maybe. Something to think about.
