I am about to replace all 4 of my 48" T5 HO bulbs. They go into a Current lighting system. They work together with my two 14K 150W MH bulbs. Right now I am running 2 420nm bulbs and 2 460nm bulbs. Looks good but want to find out the optimal bulbage.
So I need your opinion... regardless to brand, unless its that important, what combination of bulbs would you put in? My goal is for optimal growth not so much "look".
The 4 main bulbs available seem to be 420, 460, 10K and 6700K. Considering the MH I have now what would you combine and why?

Since you're just using the T5 for suppliment you probably don't need to add to much into the whiter spectrum. You can try the ATI Blue Plus which have the color of an actinic bulb, but MUCH higher PAR. Maybe throw in a Giesemann or UVL actinic for the little extra "pop."
