Collection: Bulbs (MH, HPS, CMH)

High Pressure Sodium (HPS), Metal Halide (MH), & Ceramic Metal Halide (CMH) Bulbs available.

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.

Double Ended (DE) HPS grow lamps are typically used by commercial growers with large spaces and high ceilings. DE HPS grow lights produce higher intensities of light due to the design, construction and internal pressures of the arc tube (light generating source).
