AMEN to PF for making the lamp development at UVL happen. That type of shit doesn't happen very often ya know. I haven't even seen anyone thank PF for doing it. So THANK YOU PF!
I'm going to give your theory a try PF. I popped in new arrangement of T5's in another fixture. I think I have about 6 individual light tests going on with constant environmental variables at each station. The new fixture has from left to right, 1 UVL 75/25 for the violet/indigo/green/orange, 1 UVL 660, 1 TrueLumen 460, 1 UVL Red Sun. Yeah you heard me, I'm giving the Red Suns another chance. I even set up the light fixture with the red/blue counterparts of Chlorophyll A and B right next to each other so booooyaaaa, it's gonna work even betta now! hahaha
It's really putting out a nice magenta/pink/orange color that "looks" like it's going to work well.
In case a few of you are confused, I am running 4 lamp fixtures instead of 8 or 10 or 16 lamp fixtures and am trying to get better results by using either 4 different lamps at a 1:1:1:1 ratio or 2 different lamps at a 2:2 ratio. I think it's possible by fine tuning the spectrum as much as possible. I'm trying really hard to do without any white triband, but I do have a couple fixtures with 1 partial white lamp(UVL 75/25 or Aquablue special for example).
