High pressure sodium grow lights provide red spectrum light, which is beneficial for the flowering stage. We also stock metal halide lamps for the vegetative stage.

HPS provides efficient lighting and  a long life span, saving you money over time.

HPS lamps generate a lot of heat, it's important to hang them 12 to 18 inches away from the plant to prevent heat damage and stress to your plants.

The table below provides a summary of coverage and hanging distances for the most common metal halide and HPS bulbs.
