Biocube 14 gal as refugium?

So i'm using my 14 gal biocube as a refugium and i was just wondering what kind of light is sufficient enough to provide for the plants. Can i just turn on the regular light or do i have to turn on the blue light as well? Thanks guys!

 

I use a 67k Power Compact on mine. I was going to put in a 50/50 white/actinic light in cause one of the stores told me I could put a coral in there if it was stinging my other corals or something that would require me to move it from my display, but I just went with the single white 67k bulb. My cheato is growing pretty good under it. For refugiums I think it is best to have a white/yellowish light.

 

Hi everyone, how long do u leave the light on in your refugium? the guy at the store told me to leave it on 24/7 but i think it's a lil bit too much?
