I’m getting ready to swap out my HLG-550 for a new HLG-600 in my 4x4 . I’ve always ran my HLG-550 between 20-24” above canopy during flower, but I see on the website it says to run the light 28-36” above canopy, which seems a little high to me, even with the extra 100 watts. Just curious to see what height people have been running the HLG-600 at, TIA for your feedback!
