Cannabis Plants Will Flower Under 14 Hours Light

My last grow I did 14/10 for flower.. What a mistake.. Too much leaf growth and it all turned out larfy as hell! 13/11 worked much better but I'm sticking with 12/12..

Im surprised I didnt know this, it seems like its a common thing apparently that they can flower at 14 hours. And Im over here thinking I made a breakthrough bahahah.

Pretty sure trigger times are genetically dependent. Had a strain this summer flower across the equinox (14.50-9.10 day night)
Had friends bitch about bloom not triggering til early September (13-11)
Since I'm always running new strains think I'm going to start testing for trigger times

From what I've read 14.5 hrs. is the magic number to initiate flower..

If that was the case then 1/3 of the planet would have no veg season

please read the attached study. 14L/10D straight through for high thc varieties caused a reduction in flower mass and thc by 2/5, but, switching half way through the flowering period to 12L/12D would in some strains result in a DOUBLING of flower mass and thc. non responsive strains were not affected negatively

also, 14L/10D to 12L/12D had about the same results as 12L/12D to 14L/10D. and they also tested 10L/14D which could also be used in conjunction with 14L/10D

interestingly, for high cbd strains, 14L/10D straight through resulted in doubling of flower mass and cbd, and they speculated for high cbd strains that could be increased with over 14 daylight hours
