warm white or cool white fluorescent light?

Hello all,

When there is not another option -at least for the time being- is it best to use warm white or cool white fluorescent light tubes?

I've never been able to tell much difference, but when I've used ordinary fluorescents, I've used them both, half warm and half cool.

Neither is particularly strong in the blue end of the chlorophyll absorption spectrum, but the cool white emits a greater flux in both the red and blue ends - go with it.
