What is HPS plant growth light?

The HPS (High Pressure Sodium) growth lamp is a high-intensity luminosity that is emitted when an electric current passes through a narrow arc tube composed of a mixture of xenon gas and mercury and sodium vapor.

HPS technology plays a vital role in growing indoor crops today. It involves HPS bulbs with different shapes and sizes. They are usually opened by pulse activation. Please note that the spectrum of HPS bulbs varies greatly between different manufacturers and different lamps.

HPS Spectrum Output

Different grow lights produce different spectrums of light. Plants grow responding to the color spectrum of the light they're receiving, this process is scientifically known as photomorphogenesis.

HPS bulbs emit a golden-yellow light that is specially good to maximize budding and flower production. Their spectrum what makes HPS bulbs emit their respective golden colored light.
Note that we said "PAR spectrum." PAR stands for Photosynthetically Active Radiation and is light between 400 and 700 nanometers which is specifically used by plants at certain ratios for photosynthesis. HPS bulbs also produce a little light outside of the PAR spectrum, like infrared but this light is generally not useful for our plants and greatly contributes to heat production.

HPS bulbs tend to produce most of its usable light as yellow and red light. This is why some growers choose to supplement their HPS grow lights with Metal Halide (MH) lights which have a green-blue dominant spectrum for more balanced light spectrum.

High-pressure sodium lamps are a good choice because the light they emit is stronger in the orange/red spectrum because they are rich in sodium. Planting young weed plants with HPS bulbs will ensure impressive vertical growth. This is not only a good growth light at the flowering stage, but it is also a more economical choice. Below are 3 very useful HPS grow lights, I hope they can help you.
