Rotating Lights

Is it a good idea to rotate lights to save on power? I have a 1000W MH and 1000W HPS, I want to have one run for 6 hours and than the other one turn on while that one turns off and when I add a third light would it be a bad idea to have part of the day 3 running, part of the day only 2 running, and part of the day only 1 running?

Is this generally a bad idea? Am I being to cheap here? What should I run more often HPS OR MH (all phases)? Thanks a lot

generally I would say that this is a bad idea. During the hours of light I would say that you need to give the plants as much light as possible. Scrimp now and you'll pay for it later.
