I’m not saying that panels don’t work, and certain panels are better than others. CLW is more honestly assembled, has mostly been one with good reviews, I think they use something like legit Cree or Osram diodes and are built in America? I will say, for the price, a QB might be a better route these days, though.
I got a good 3-4 ounces from 2 ViparSpectras before. They were a bit less dense, and I cut a bit early, but it was decent bud. They can work. I just think if people can skip that step and go to QBs, COBs, or strips, they probably should. 2.5-2.7 micromols per joule, particularly for relatively similar or better pricing, just seems a bit hard to pass up.
