Metal Halide Lamps

Metal Halide Lamps output blue light which is beneficial in the vegetative growth stage. We also stock HPS lamps for flowering stages.

Metal halide 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.
