Well, see that's the problem with just relying on the labels on the box or
things like color (eg 4000k) or CRI. None of these are truely indicative
of how much red spectrum the bulb provides. And they can be quite accurate
in saying it would promote plant growth because it provides plenty of blue
spectrum which plants also require in photosynthesis.


What should one look for in a bulb then, if not color temperature? What
about using two different bulbs in combination? What is everyone's personal
favorite?
