Colour Temperature and planted tank

Hi guys according to the spectral output of a lamp generally plants with a clorour temp with 3000 K. out put tend to have more red and green than 6500k, stil;l why do people tend to recommend daylight lamps for planted tanks.

Cheers ppl.

My simple answer:

Daylight simulates all spectrum as general. It emits red as well as blue spikes (and the green spike usually appears as brightness in human retina). Plants have several kinds of chlorophyl which are more sensitive to certain colour spike, and they do adapt to the available spike, hence they change appearance. Some plants have a limitation to that, and some may grow redder or leggier, etc with only one kind of light spectrum. So people accept daylight as a cheap, working option to growing plants...
