How long was your switch over from 18/6 or 24/0 to 12/12? Most use a 24-36 hour "Dark" period

I'm sorry I dont understand your question! are you saying that one should turn off the lights for 24-36 hrs after vegging (18-6) BEFORE going 12-12 and flowering? if so thats the 1st I've heard of this. :wtf:
