any1 tried 24+hrs darkness

Hey everyone! I was just reading up on some grow info. And I read that giving your plants 24-72 hours of complete darkness, when switching from 24hr light, to 12hr light, can greatly influence the transition between the veg, and flowering stages. I've never tried this before. I'm looking for any/everyones opinion/exprience with this. Any/all input is greatly appreicated!!!

it does help alot and it does especially well when you are growing more than one plant because it kind of gets them all on the same page so when you turn the lights back on they are all prepared to flower and it will keep them closer together in growth but that is my opinoin listen to others and pick one that works for you
