What bulbs or combo of bulbs would be ideal for a 4 by 55 watt jbj light fixture? I currently have 2 10k bulbs and 2 50/50 bulbs in it from my last reef setup. This would only be for clones or young plants. I have a 400w mh for veg that I'll switch on once they can take the light.
Is this the best or should I go straigh 10k bulbs?
