I got the 480W bar setup, been struggling to find the sweet spot. Seems that Samsung LM301H with CREE reds is a powerful combo. Anyone have experience with it, or other wattage Kingbrite bar LEDs??
Growing in coco and having a strong LED I have to feed extra calmag despite using coco spesific nutes (manufacturer says no need to add calmag…)
Even when trying to use correct DLI and PPFD I still feel that I should use lower numbers than normally with this one…
Anyone? Pretty please and kief on top…
