How many blues are you using?

Par38 fuge light with 10 reds and 2 blues lights my 12x10 screen just fine.

I use 9 red, 2 blue. And I'm running it at like 20% power because any brighter and the screen gets a brighter yellow green growth while the surrounding edges get a darker green growth. If you get away with 1w LEDs, use those
