2 of these is more than enough..no need for 2k$ in lights
The big downside of those, and the HLGs for that matter, is the poor light spread, almost as bad as an HID. Look at that PAR chart, the intensity at the center is over twice what it is even at the edge of the 3x3 square. You'd have to keep the light at 24" over the center without CO2 to prevent burn while the edge of the 4x4 area is receiving less light than what you'd want in veg. That's why I'd recommend the ROI over the HLG, looking at those charts reminded me of just how much better bar style lights are. It honestly makes me hesitant to even recommend HLGs anymore.
