Difference between 600 watts and 850 watts?

  1. I want to save a little on electricity. I have about 850 watts going now with my ballast at 75%. I want to lower to it to 50% to save a few bucks on the electric bill. Would it affect the overall yield of my girls that much between the 250 watt difference there? My grow tent is 8x5x5 and I have a metal halide bulb about 4 feet away from the girls. They are indica hybrids, a sativa, and a full indica. So a nice mix.
