LED vs 1000W Double-Ended HPS Medical Cannabis Grow Test

We are testing the top rated LED fixture vs the top rated 1000W double-ended HPS fixtures at our Medical Cannabis grow in Northern California. We are 4 weeks into the flowering stage, and we are comparing the BML SPYDR 1200 vs the Gavita, ePapillon, and Phantom DE HPS fixtures. We will post updates after harvest. We did a lot of homework before we purchased these lights, and we could not find any head-to-head comparison tests. Hence, I hope our video is helpful to anyone considering these systems.
