So Samsung manufacturers it's LED's in China and Korea so I don't know if it is fair to call them "Chinese knockoffs". I am all for American manufacturing, but i also buy what I can afford. And while everyone is entitled to their opinions, and I respect that, I would never want to take our grow tech back to the 70's and 80's. We have come too far to go back now. Part of developing as a grower is adapting to new things. Whether that be lights, automation, grow media, fertilizers, materials and so on. If a guy likes growing to HPS, I say rock on man, but I don't think I could ever personally recommend someone start their grow with MH or HPS. Unless they have special circumstances... maybe they live in a cold climate and want the light to help heat the grow area... idk.
