So what’s the breakdown on HID lamps as of 2014? I’ve seen a decade of pseudoscience on the matter and I think results speak for themselves. I have used many of the brands of HPS and MH sold in retail stores. Different brands make different claims about spectrum and longevity, etc. From my understanding sodium emits strongly in the yellow, there’s no way around that. They can filter out those wavelengths, but not change them - for this you’d literally need to stretch space time with gravity. But MH lacks the intensity and is less efficient per watt. I’ve done experiments of various 1K MH brands vs. various 1K ups brands, and the same with 600s. Always get heavier yield from HPS, tighter nugs from MH. I’ve never noted any significant difference between brands when globes were the same age.
