Only running actinic/blue channels

[Anthrax15]

I apologize if this has been answered before, couldn't find a thread after searching. Right now I am using AI Hydra 32's and really enjoy the blue spectrum. I was curious if I can get good growth/color only using the Blue/RB/Violet/UV/Red channels as long as the PAR is at the appropriate levels? If I need to supplement some Cool White channel into there, I will but much prefer the deep blue look to the tank.

Any running a similar spectrum with good success?

Cool white just adds green to your mix. Cool white is just royal blue plus some green and a tiny bit orange/red.

Has anyone had luck with growth just running blues/actinic spectrums?

Well I’ll tell you I added some white and sps got more colorful over the past 3 weeks, I was running Real blue for June and July with new lights. LPS seem to love the blue, once I added some white they shrunk back a little even keeping par the same. Today everybody was back to open and happy. @Big E as I believe I read his post on this matter
