Switching From Day to Night Lighting--Important Question!

[demoreal]

best way to accomplish what you trying to do is after your last 12 hours of light just leave the lights off until you want to start the light again and set your timers to 12/12 after that...i've done this before and a few extrea hours of dark is not going to hurt...but extra light can..so just extend the dark hours until you want the lights on:thumbsup:

I have done that too. It will work perfect.
