You guys are talking about interrupting the dark period of a cannabis plant with the intention of having a positive effect on yield or plant health... I think this has been thoroughly disproven in controlled indoor settings. True, outdoor plants must contend with reflected sunlight off the lunar surface and as of late, light pollution from neighboring cities. But while they have evolved to grow under natural photoperiods, I have to imagine beneficial levels of light during the dark period are small or nonexistant. By that I mean total darkness is more beneficial than an interruption. Or so I believe. Feel free to contradict me, I am by no means infallible.
