Leaving the plants in darkness won't help the light mistake. Just go back to normal and, get a timer like Jaam said. Good luck man.It might be ok, don't panic yet.
thanks gang. well you see it was on a timer and went off last night, but for some reason they came back on got me, I think I have a ghost don't laff im serious
I had the same thing happen minus the ghost. My timer got knocked when I was feeding and I didn't realize it until the next night. So far everything with the plants seem fine and that was a few weeks back. Hope you have the same luck!!!
