Dark Period Tending & Caring?

Cannabis plants are not cameras. How long does a flash of lightning last? It is highly likely that turning on a light in the flowering area will be done for somewhat longer than a lightning flash.

You have the ability in an indoor grow to provide total darkness for 12h/day- and that's exactly what you should do. There's simply no excuse to turn on a light in dark hours. Schedule the light cycle to suit when you have time to work in the op.

Who's to say that wild cannabis plants don't turn hermaphrodism through full moon, lightining or a man just shining his car lights at a plant.
Pretty simple, the moral of the story is NO light during dark hours!
