I think you did fair research because I was going to suggest HLG before you said you were working with limited height. That light does look really badass.Ah okay. well, my tent is 80” in height. Using dwc cuts out 15” of space with the buckets, then if I used a light like the HLG 600 or 550, and had to hang 24” + above the canopy, and 15” recommended below the roof of the tent, that only leaves me with 26 inches of actual plant height to work with. Which id like to be able to grow plants a little taller than that haha.
