As was mentioned in the basics thread, I am working on setting up a controlled experiment using multiple independent (and isolated) systems using various LED combinations in an attempt to 1) pinpoint the optimal growth spectrum and 2) monitor nutrient uptake. #2 is really secondary, but since it only minimally impacts #1 to sample and test water, why not (gotta do it anyways). There may be other pertinent data, but mainly I am working on this to try and pin down the spectrum issue, as it seems there has not really been any study to date that really shows the optimal artificial spectrum for growing algae for our purposes.

It may also reveal the dominant type of algae grown under each given light source, or combinations of light sources, as well as the efficiency of said algae.

Should be interesting. If I have the time, I'll periodically post about the experiment, but the detailed thread about it is not on this site.
