T5 color combo?

[mrhasan]

I like spectrum between 14000 to 16000k. 10000k would give you the best growth while actinics five the pop. Bulb manufacturers have blue bulbs (not purely actinic), which, unlike actinic, gives some good par depending on the reflector. So you will see most of the people use blues instead of actinic. Then theres purple/pink which helps with the color pop. I have used 3 blue, 2 10000k and 1 fiji pink. That gives a 14000k look. Now I use 4 blues, 1 10000k and 1 fiji pink. This gives a pleasant 16000k look. Growth wont be an issue unless you use actinic since they are supplemental spectrum.

Kz and ati are rhe best out there. KZ is expensive but throws out a bit more par. But I dont think you will notice any difference to justify the extra cost. I just grab whichever is available. HTH
