T5 color combo?

ATI and KZ make the best bulbs hands down.

It comes down to preference to an extent, but par values are important too. Actinics have almost no par, where as a Blue+ is one of the highest par bulbs they have and has a very similar lumenescent effect of a actinic.

I run an 8 Bulb fixture, with 2 Blue + on a seperate ballast which comes on 2 hours before my other 6 bulbs, and runs two hours longer than the other 6 as well.

The other 6 are two ATI Aquablue Specials, 1 Coral+, 1 Purple+, and one more Blue+

I get about a 12-14k look with these bulbs which is what I'm shooting for. Adding more blue+ bulbs would get you closer to the 20K look, and more ABS's would add a bit more of a yellow spectrum, and the Coral+ and Purple+ adds the purple color.

Nick, I had trouble making up my mind when I setup my 8 bulb, but knew I didnt want a lot of blue; I prefer a bright, natural look.

So to cover the spectrums for growth and looks, I went with;
2 Superblue
2 Coral Light 10K
3 Coral Light II 14K
1 Fiji Purple

I control each of my 4 ballasts independantly and have played around with the timers over the last 20+ months to balance growth against our viewing times

Thanks for all the input guys. I appreciate it. Quite helpful.

On mine I've been using 3 Super Blues(20,000K), 1 Fiji Purple, 2 Coral Lights(10,000K) and 2 New Generations(14,000K). I prefer more of a bluer look and the Super Blues get me there.

I have always loved the 20k radium look, I went with 6 bulb plus, 1 purple plus and 1 coral plus. The look is not as blue as leds but pretty close! According to ATI, the blue plus puts out quite a bit of par and usable spectrum considering its a bluer bulb.
