Right now im running 368watts give or take 10 watts of CFLs and 150w HPS check out my first sig its the first test run in my box flowered with 8 26 watt CFL for 2 oz dry and that was with half 2700K and half 6500K also it was two weeks early so it would have been more. Im a big fan of HPS with mixed CFL spec for side lighting give you tight nodes and dense nuggets.
