Hey Tom,
If I were you, I'd think about replacing the 12ks with either 10ks or 6500, rather than switching out all of your actinics.
Sorry, just noticed you had the PC bulbs as well.
I'm starting to agree with you. Maybe I'll swap out only two of the T5 actinics for 6500k and see what that does. The PC bulbs I have coming in the mail are 420nm so that might be too dark without at least 2 T5 460 nm actinics along.
Thanks for the help,
Tom
