That depends on the color temperature and your preference. for the plants, the closer you get to 6700k the better. I've used bulbs in the past that were good for plant growth but horrible IMO
visually. That's where two bulb fixtures are nice. Something for you and something for your plants.
Since these are low light plants, they may grow just as well with either bulb. If that's the case, then it might be a matter of preference on your part; warmer on the left or cooler on the right.
