HID grow light bulbs are a sealed tube filled with gas that creates light when the gas is ignited by two electrodes that arc current between them.

MH grow light bulbs should be used for the vegetative phase as they give off a blue to white spectrum

HPS has a red or orange tint and is used primarily in the flowering phase of your plant's life.

CMH grow light lamps are a relatively new source of HID light that is a variation of the traditional Metal Halide HID lamp.
