If there are two switches and you are able to control the bulbs (3 on/3 off), then I would look into 3-10k daylight bulbs and 3-03 Actinic bulbs. If there is only one switch, then consider some 6500k or 50/50 bulbs.

That sounds just fine, I think that a lot of it is personal preference. Most would recommend half of the bulbs being actinic and the other half either 50/50 bulbs or 10K. I don't think you can go wrong with any of those combinations.

alot of it is personal preference on how white or blue u want it. the 6.5k will give you more par but more yellow and the further u get away from that the less par u have. Best thing to do is get a bunch of the bulbs that you want to use and keep playing with the color combinations. Either way u will have extra bulbs that u can keep when its time to replace them
