I've only running mh since xmas(250w 10k bulb)
I was told the lower k (below 6k)would be too yellow and give you more of an algae bloom.The 10k bulbs should be fine,just gradually increase amount of light(start with lights higher up)or slowing increase amount of time they're on over a couple of weeks.Maybe the guys who been running mh longer can be of more help.
