"So you think 5:1 is the optimal ratio?

Don't know about optimal, but I think 5:1 is a little red heavy for veg.
I'm running at 4:1 in the bloomery trying to limit stretch.

Should I split up the blues in the "red" panel using two wavelengths? If so which nm blues should I use? "

These should help you decide.
