i got a nice digital outdoor light timer (outdoor timers come grounded) for like $28.99.

Works like a charm... and you can program ~30 light cycles all at the same time on a weekly schedule.

EDIT: you want an grounded timer if you plan on using a surge protecter to power many applications.
iwantFUEGO Reviewed by iwantFUEGO on . 12/12 Strictly ??? I have started my 12/12 cycle 7 days ago. I dont have a timer yet. My work schedule usually allows me to turn on at midnite and go dark at noon. But I may go in early or arrve home after midnite every so often.. Will it cause any problems if some days I start darkness 1/2 to 1 hour early so that day it would be 11-11.5 on and 12.5-13 off. Basically I wanted to know ( or become one with the knowmage effect ). if the 12/12 needs to be adhered to strictly or can it vary a day here and there. I Rating: 5
