Sunmaster 400w Metal Halide Bulb

SunMaster MH Veggie Bulb (Metal Halide Lamp) is specifically for the vegetative growth phase. Plants grow vigorously, healthily, with many new shoots and shorter internodal spacing. Industry-leading lamp: Stimulates a higher chlorophyll level for greener, healthier, and more productive plants. Stimulates a large leaf area/mass. Encourages a greater number of internodes, maintaining a compact plant shape. Compensates for the spectral blue deficiencies of standard HPS light. Provides up to 10% more red light and 70% more blue light. It is ideal for mother plants and cuttings. Remember that you will need a different bulb for the flowering phase. We recommend changing the bulb every 3 grow cycles to avoid growth defects that negatively impact production.
