At Holland Hydroponics we stock a full range of HID (High Intensity Discharge) horticultural grow lamps which includes High Pressure Sodium (HPS) and Metal Halide (MH) for all indoor hydroponic grow rooms.
The HPS grow lamps are available in Blue Spectrum, which is recommended for vegetative growth, as well as keeping mother plants, and Red Spectrum, for the flowering stage. The third option is Dual Spectrum, these have been specifically designed for use throughout the entire grow, without the need to switch lamps when the plants start flowering and are often considered more user friendly and of course, the cheaper option.
MH (Metal Halide) lamps are predominantly know as Blue Spectrum lights, they run slightly cooler than HPS and are perfect for the vegetative stage, or for keeping mother plants, with many growers reporting that MH grow lamps produce healthier, more vigorous plants during the early growth stages compared to High Pressure Sodium.
Available in 250w, 400w, 600w & 1000w and when choosing your grow lamp, please make sure that the wattage of the lamp matches that of the ballast being used, if there’s a mismatch, this could permanently damage the lamp and/or ballast.
