Color Temperature & Bulb Choice
I usually haunt the African Violet forum but am coming over here to get enlightened about color temperature.
Most African Violet growers including myself use one fluorescent tube each of warm white (3000K) and cool white (~4100K), which is generally standard in the world of AVs. Until recently I had mistakenly thought that warm white and daylight bulbs (5000/6500K) were the same thing and apparently they aren't (and that daylight is actually closer to cool white).
Because daylight bulbs are similar to natural sunlight (~5000K), why wouldn't growers use daylight tubes exclusively instead of continuing to mix a warm and cool tubes?
