Best HPS Grow Lights – Top 3

HPSs or high pressure sodium grow lights are HID (high intensity discharge) lights – this means that they work and emit light when an electrical current passes through a tube which is filled with gasses like a mix of sodium and mercury vapor and the inert gas xenon. It also means that the light will be strong in the red/orange spectrum at around 2200K – amongst other plants, this light is excellent for growing marijuana plants.

They are known to provide the yellows 570-590nm, reds 630-750 nm and oranges 590-630 nm color spectrum which is absolutely amazing for flowering stages and budding stages.
