I saw this in a thread previously, but I can't find it now:
What kind of switch do I need to run my 2 grow rooms on alternating 12-12 cycles from one ballast? (That's simplifying it, actually to run 12 lights from 6 ballasts). I want to run my ballasts 24-7 and just use the switch to alternate light in my two flowering areas. I can save the extra electrical draw while "firing up" and save some startup $$$ at the same time.
Thanks
