I have a 4 bulb setup, and right now that consist of 2 actinics and 2 daylights. Since there are additional options out there, I was wondering if I could use a spectrum of 4 bulbs, like one white, a pinkish white, a standard actinic, and then a darker actinic? Is tht something I could do with this few bulbs, or should I just stick to what is working?
