Metal Halide Lamps

Metal halide (MH) lamps are a type of high-intensity discharge (HID) lamp. MH grow light produces light through an electric arc and a mixture of gaseous mercury and metal halides. MH bulbs are used for veg, also known as the vegetative stage because this technology puts off a cool blue wavelength, which is why it is best for vegging. This type of light forces bulbs to build thick, sturdy stalks, and robust, leafy foliage.
