Can Anyone Answer This Brain Buster!!

someone to told me that when u go from veg mode 18hrs to bud mode 12hrs u shouldnt just switch the timer 12/12 u should do it gradualy untill u get to 12/12 is this true??? does it make a diff will it make the plants buds big or is it just bullShit

bullshit. flowering is induced by a chemical trigger that only happens with 12 hours of darkness. anything but a straight flip is a waste of time.
