The Sunmaster Metal Halide grow lamps are a staple for old school growers who prefer to use a dedicated blue lamp for vegetative growth rather than a dual spectrum.

Producing a predominantly blue spectrum, Sunmaster Metal Halide’s will keep internodes closer together, allowing plants to stay squat, but also encouraging stalks and stems to become robust during the 18/6 light schedule. This gives plants a strong framework before they begin the crucial flowering phase.
