We are studying a light that it's spectrum can be adjusted.I think the spectrum is not overly harsh and rather forgiving in comparison to a purple looking led board
glad to hear that you come back, bud. take a chair and watch the show.I'd just like to update this thread,,,
All my other leds have died,,, the only one left is the Mars,,,this thing does not quit,,,it's the workhorse of the led industry,,,use it as a Frisbee and it will still grow a small set of plants afterwards
