Some of these grow lights can be used by growers across all phases of the plant’s growth cycle while some of them are phase-specific. While Noble gases such as Argon or Xenon form the primary element which is ionized, the secondary element in MH lamps are metal halides such as sodium iodide while the HPS lamps carry sodium vapor mixed with mercury which give them a different sort of a color. One look at the lights and you can tell that the Metal Halide (MH) grow lights function at the bluer end of the color spectrum while the High-Pressure Sodium (HPS) lights function towards the other end – and have a reddish light. One of the biggest advantages to growing with LEDs as compared to growing with High-Intensity Discharge (HID) bulbs like High-Pressure Sodium (HPS) and Metal Halide (MH) bulbs is that LEDs consume a fraction of the electricity of an HPS or MH bulb.
