Hey Fermentation...

Dude, I'm in a hurry, so I'll reply more appropiately later...

But yeah, when I contacted the company, the guy gave me the specs for their LEDs... and there's the central nm, and a "range" of wavelengths that the LED also produced... so you're right.

I'll write what happened with the custom setup later...

BTW: LOL!!!!
"Ferment... Now damnit!"
lol lol
