About
Ceramic Metal Halide (not to be confused with straight Metal Halide) are the unsung heros within the HID family. CMH lamps are more efficienct and their specific fuller spectrum give better growth in veg, and less stretch at the flip to flower thanks to the more blue in their spectrum . Growers can get great results with a mix of both CMH and HPS lamps in their grow room.
