hey gorillaz. yes you can combine all sorts of lights to get the right intensity and strength no problem. usually what you want to do is basically complement this or that weakness of one light with another. for example 1000W HPS, but it doesnt reach the the corners or underneath your canopy so decide to also add LED strips to cover what it doesn t cover. So the idea is to maximise your light coverage, maximise your spectrum or increase the intensity of the light. I see you have a lot of different lights, but all of them are top down kinda lights. Mostly growers will mix and match actually and vary top down and other kind of lights like a led strip , or a CFL on the sides of the grow room. This though, really helps. so does adding more light. So you're doing the right thing. hope this helps 🚀
