Just started flowering. I know plants need 12 hours of dark to start flowering, and that it's the 12 hours of dark that keep them flowering. In nature, they must surely, at some point, receive more than 12 hours of dark (because once the natural light cycle shifts at the equinox the nights get longer). Is it ok to replicate that indoors, to save power? Can I put my plants on a 10 on, 14 off or 11 on, 13 off schedule?
