Thanks for the help, I got it all figured out now.

One more thing, I've heard that different ballasts can make your lights seem more blue?

I'd like to avoid getting too blue, I'm sort of going for a crisp white but I've also heard that 10K bulbs are very yellow, though that may just have been in comparison to higher K bulbs. I understand how Kelvin ratings work, I just want to understand how I can keep my 10K (which should be blue enough for my taste since I'll be running T5HO supplemental lighting) from looking yellow. I want white, like BRIGHT WHITE.
