Sun System is a leading producer of grow lights, and their MH and HPS grow lights are many growers' choice.
Why use MH and HPS grow lights?
MH and HPS grow lights are one of the most tried and true grow lighting technologies. These are commonly used in commercial grow rooms, because they are low cost and incredibly intense lights.
Metal halide grow lights are best used for vegging plants, and high-pressure sodium bulbs are for flowering plants. The spectrum they emit contributes to when they should be used, as MH give off blue light and HPS give off red light.
