Short for “Metal Halide”. MH’s are a type of HID light that has a blue tint and encourages short plants with small node spacing. MH lights are almost always paired with an HPS light. This is because Metal Halides are great at growing plantsin the vegetative stage, but they’re not as good in flowering as an HPS.
