Green is useless as far as I know.
In fact, it seems you can buy green lights for working in your grow room during the dark period, and it doesn't disturb the flowering process.
Also, I read somewhere that white were mostly blue anyway, but will make pictures look much more natural. My kessil h350 magenta has ZERO GREEN. All my photos show the "green channel" as pure black in photoshop. The kessil is a quad spectrum (2 red 2 blue)
I'll know in a few weeks if removing the 600w hps was a good idea.
"Prohibition...goes beyond the bounds of reason in that it attempts to
control a man's appetite by legislation and makes a crime out of things
that are not crimes. A prohibition law strikes a blow at the very
principles upon which our government was founded."
-- Abraham Lincoln, December, 1840
