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.
