I've been doing some research on light and what works best for growing and I have discovered the consensus to be that predominantly blue light is best for early stage growth (vegetation) and predominantly red light is best for later stage growth (flowering).
I have also read many times that the more lumens/watts/PAR/etc. the better.
So I started researching light and color and learned that to produce red, blue or any other color of light from a particular light source, the other wavelengths of light must be filtered out (or subtracted) so that only the wavelength desired remains.
In other words, a "red" light source is basically a potentially more luminous white light source (that would contain all the reds you would be producing with the red "filter" on) plus more light which is also deemed beneficial widely by this community.
In essence, it seems to me that you get less total light with colored lights and gain absolutely nothing because the unfiltered light would already produce the same amount of any particular color after filtering out the other wavelengths.
To put it simply. Coloring light = subtracting light.
Thoughts?
