However it seems unlikely they would explode into flower over a night without light lol. A lot of people use re veg as a technique. A way to keep supply up. They'll veg harvest then re veg to get another harvest out of it. Or I personally will flower to see the yield potency etc. Of a possible mother or seed bearing plant and when I find "the one" I will re veg and clone it for a while then throw it out back (when I had one ) at the beginning of summer and come oct. Its a fackin beast.
How does one day of power outage cause flowering? This typically takes 2 weeks of 12/12.
This wouldn't hurt it, it's random shit like a single light being on during your dark period that causes hermies. A strong plant will reveg without problems.can you really damage a plant by re-veg after short periods?
For instance, if i switch to 12/12 for a week to see which are females, and then go back to 24/0 to veg for another little while..... can that negatively affect them?
