Sorry if this has been asked, but I looked and didn't see anything. But what exactly is the difference in the colors of the light. I saw a post with someone saying that had too much white light and needed to switch a bulb for an actinic.

I am currently running 2 x

on my 20g high. Is there any reason to switch the bulbs for other colors?

Thanks

to replace which bulb - one of the whites or one of the actinics? What are the benefits of that?
