novice11,
My set up is as follows (in this order)
UVL 454 W/internal reflector
Fiji Purple
UVL super actinic w/internal reflector
ATI 12k aquablue speacial (I think that the ATI blue plus is probably a more viable bulb here)
UVL 75.25 w/internal reflector
Fiji pruple
these lights will give you a good spectrum to veg from, with any empty space I would use more blue (blue plus)(actinic) bulbs for veg and more red for flower(redsun), or the Fiji purple is a good mix of both blue and red, pr0fessor suggested to me to look at the Fiji purple as like a "Base" and to build from it to get what you need, depending on veg/flower and how many tubes your using. As for the order of the lights, I wouldnt put the same bulbs next to each other and if I remember correctly I think that I remember reading not to put the red bulbs on the ends. (not sure how serious this is)
this is just what ive gathered and I am by no means experienced!
