My point is.... When everyone figures out that speed (300nm to 400nm) is the only thing good about these lights. The next step will be seeing that the good (speed) don't out way the bad (uv-b). There are much better ways of getting the plants clock moving faster IMO.
heres a curve ball

can anyone try an addition to this experiment if the uv-b light was color screened to filter out the blue? i've dabbled with photography and color gels to filter out certain lights to get that 'perfect' effect in some shoots, i figure the concept should be relative in this particular case.. if this could be accomplished, perhaps we'll be able to see the true effects of uv-b without spectral influence
