I have a very good idea of what to do with UV man been researching a long time, im just not going to step into that arena right now, and yea the BS has a UV led in it ONE, I called and asked why my one of my LED's was out on my BS that is the UV led, Its going to look like a burnt bulb on your panel but its not if its BS panel. They get calls on that all the time. I know if i use the wrong NM of uv it can hurt my plants i also know that some plants just dont like UV at all, those tend to be indoor only plants, you know the ones you throw outside and they shit on you for no reason. I also know there are plants that suck up UV like its water, take AK47 for example that plant fuckin LOVES UV light. Do your eyesight turn green after lookin at your panels? If it does they are emitting UV rays, no matter what the manufacturer says regarding that. UV makes your vision turn green tinted if you get too much of it.
I also beg to differ about UV being a way to frost plants, like i said some plants LOVE uv light others say fuck you at teh slightest sign
