I mean, the sun doesn't magically shift its spectral output, so how does that factor into decreased yield if say I used warm white CFLs throughout the entire process?
The Sun Does magically Change the light spectrum as the seasons change. With a little help from his friends. As the Earth Rotates around the sun, and the axes of the Earth pushes the North Pole Away from the Sun, The Sunlight hits the place you are at, at more of an angle. The light has to tavel through more atmophere to reach you, and is not as direct as during summer months. So here is you change of light spectrum from the sun.

Also, As I always thought, Soft light, and cool light are the same. As I know CFL's they go Cool/soft light, Warm Light, and Day Light. The three levels. You know, no one who sells these lights seem to know anything about them, which is true of most items in any store now a days. I miss the old days when you could walk into most Hardware stores and they would know where something is, and also know how to use it and connect it and such. Now they most likely do not evne know what it is for.
