How about building a set up that will alternate its light sources ther by saving on overall elect.costs.
exam:build a three light system of say three 600wt.hid,hps lights to go over lets say a 4x6 or 8 area.then when your 12/12 cycle starts you go.
2lghts on for 2hrs then 1 light on for 2hrs all in one 12 hr session.this would cut your over all electric expence by 1/2 on your lights alone.this can be done I think because plants take along time to assimilate light.so the diference in lighting would make no difference to the plants.
