I stumbled upon this site which said growing under these lights is the trick to getting the best plant growth. Yet I cannot locate any place that actually sells these lights, namely the T5 BioTropic bulb, red T5, and blue T5 seem all but non-existent. And if they are on the market it is certainly a "gray" area. I am sure this is a hoax, I am just wondering the validity of using the spectra they show and if it is something I can mimic.
