Used HydroFarm 2000W Grow Light Hood and Sodium Grow Light Ballast Converter!! You need the Ballast for the high powered lights, and this is a light that requires it so we sold them together. We plugged this in, and it works perfectly! This is used, so it does have some cosmetic flaws, but that doesn’t impact how well it works! This is a bit bulky and pretty heavy, so if you are nearby, come get it local pick up in Fort Wayne, IN to save yourself from shipping costs!
