We are testing the major rated LED fixture vs the major rated 1000W double-ended HPS fixtures at our Healthcare Cannabis develop in Northern California. We are four 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 right after harvest. We did a lot of homework ahead of we bought these lights, and we could not locate any head-to-head comparison tests. Therefore, I hope our video is valuable to any person thinking of these systems.
