Hello there everyone I have a question I've been vegging now for 40 days now and i want to start flowering now my lights are on from 6pm to 12 noon and my dark stage is 12 noon to 6pm. During flowering I want my light cycle to be from midnight to noon and dark from noon to midnight what is the procedure to accomplish this? Thank You and your input will greatly be appreciated.

wait until 12 midnight then set the timer to go for the 12 hours until 12 noon the next day.

As long as it on for 12 hrs & then off... no problem. I have two flowering so when one turns on...the other turns off. Some say the Electric is cheaper in the PM Hours, as mentioned above.So that is good u r going with 12 to 12. Peace & happy Gardening

changing your sunup and sundown may stress your plant a little, Id keep the sunup and sundown at same times, and just change your timers hours.

You might want to explain that because you can't keep your sun-up AND sun-down times the same if you switch from 18/6 to 12/12
