Indoor orchid growing

[iiwii]

I recently found this board after getting sucked into orchid growing and just had a couple questions about indoor lighting. I am considering buying a T5 light fixture probably only a two bulb 24". Now reading through posts i saw that you need different color spectrum for vegetative growth and then flowering. Would a T5 Hydrofarm structure cover all the necessary spectrum for a 6-8 orchid garden of mostly Phals with a couple Paphs. or would I need to maybe add another CFL? Also, so CF and temperature would be the most important factors in buying a lighting fixture not necessary the wattage provided. is this right?

Any help would be greatly appreciated!
