Grow and Bloom Phase Lighting Bulb Sunmaster 400 W HPS Dual Spectrum 2000K
One lamp for the complete growing cycle - veg and flowering stages.
At different times in the growing cycle, plants require different types of light radiation. Immature plants have different needs to those about to mature. To maximise the potential of a plant, to ensure that it grows strong and healthy, you need to deliver just the right kind of light radiation it needs - when it needs it. The Sunmaster Dual Spectrum lamp is a radically new, scientifically developed lamp designed for the commercial and hobby grower. Using the new Dual Spectrum lamps - which are fully compatible with your existing fittings and ballasts - you can deliver improved blue and red light to your plants at the crucial stages in their development. And it's so simple to do.
Sunmaster Grow Lamps are Tailored Spectrum for the Indoor Hydroponic and Horticultural Industry! Developed by distinguished physicists and leading agricultural researchers, the Sunmaster line has been built on the versatility and flexibility of metal halide technology.
