question

my timer has broke the last 2 days i had the l;ite on for 13 instead of 12hours lite. and the same the day before 11 insted of 12 darkness.
is this bad what should i do if i go over or under with the time of lite. ive now got a new timer but if awt happenes like this again. what should i do. i dont want hermies.thanks.craige.

An hour more or less for a day should be fine. If your asking, what should ou do after it happens again, theres not much you can undo after it has happened, we can only help you in saying make sure you try to keep it steady from now on, peace

i would get a back up timer. just in case it breaks again. you should always have a spare timer
