The halide bulbs first, than probably the actinic bulbs. I remember some of your other thread when you were asking about your lighting and 2 175w halides is pretty decent lighting all in itself and you will get more par from a less than 20K bulb.
So pick something in a mid range color and add some new super actinic VHO'S and maybe just conserve some electric and leave the other two white bulbs off as that cost a lot to run and don't add that much par anyway.
