Everything I've read suggest 14/10 for vegging and 11.5/12.5 down to 10/14 for flowering especially with landrace sativas. From my research it seems that these non 12/12 schedules cause more sativa dominant expressions to occur and even gets rid of the narcotic feeling some strains express.
I've switched to 11/13 and the Malawi x Panama #2 and #3 started throwing more pistils and further down while
#1,4,5,6 have only gotten even frostier. I've read it reduces the overall flowering time which I would appreciate and I'm thinking by switching it after 5 weeks, past the stretch that I doubt I'll see a loss inn yield.
I just want the highest quality I can grow and I've read that this light schedule promotes tighter buds with more density rather than some of the typical airy sativa buds. It starts to feel like an art to growing sativas and I've been reading on the history of the landrace strains that made it into Hawaii and the coast. It's a shame how much federal interference and the rise of indicas in the late 80's has held the sativa and it's CBD/THCV benefits back.
I hope to one day meet Sannie through a mutual friend and just talk growing and its history especially with regards to sativas.
