A lot of growers are jaded, too many LED manufacturers in the past have claimed Super LED = some HPS and it didn't perform, leaving a bad rep. But you can now see people like Remo doing LED grows. And you can't say his plants are BS. Growmau5 and Greengene also grow dank you can see the full results of with COBs. There's a few guys running those terrible mars lights growing dank nugs check out medgrower1 on youtube. I'm not saying I know which is better, but dank bud can be grown under COBs and single diode LEDs.
