@RoomPluto, after growing with a CMH, this light is incredible. The buds are so dense and there's almost no popcorn, just lower buds. I'm glad I got it during the early bird special!
@@@ShotGunBob, mostly light stress. I switched from a 315 CMH to a FOHSE Aries 600W LED at 75% in Week 3. The plants all got a bit scorched and never really recovered visually, but man did they bulk up. I dimmed down to 31% (min setting) then slowly went back up to 69%.
