High Pressure Sodium grow lights produce light which is heavily concentrated in the red/orange region of the visible light spectrum. They produce enough blue light to grow healthy plants, but the decreased amount of blue light often causes plants to stretch and become leggy. The HPS spectrum promotes the greatest fruit or flower production—think of the golden color of an Autumn sunset, and the abundant harvests associated with that time of year.

There are now several options for enhanced HPS bulbs

  • Hortilux: more balanced light spectrum with more blue light for vegetative growth.
  • SolarMax: German bulb with higher lumen output than normal HPS lamp.
  • Son Agro: offers 30% more blue light than a standard bulb.

Conversion bulbs are available for most high pressure sodium systems—these special bulbs allow your HPS ballast to produce the spectrum of a metal halide bulb. Now available...Convertible ballast systems from Hydrofarm! These ballasts operate either a metal halide or a high pressure sodium bulb with a simple flip of a switch. Get the ideal light spectrum for either vegetative growth or fruiting/flowering, without losing efficiency or purchasing expensive conversion bulbs. (Systems include only HPS bulb. Metal Halide bulb sold separately).
