The SolarStorm 440 is a very powerful 350W LED grow light. It features 144 high flux bin OSRAM SSL emitters. The system is designed to cover an area of 3′ x 3′ for Bloom and up to 6′ x 6′ for Veg. The SolarStorm 440 also features a unique supplemental "UVB mode" which is essential to develop higher potency. The sun naturally contains large amounts of UVB. HID lights do not deliver any significant levels of UVB. SolarStorm employs two unique T8 fluorescent UVB bulbs integrated into the fixture with a separate control. The UVB bulbs are typically turned on during final few weeks or “finishing” phase of the grow cycle to boost the potency of the final harvest. The SolarStorm 440 is designed to replace a 600 watt HPS or Metal Halide system. It is great for medium size or home grow operations. It can be used on light movers to cover larger areas and get even better results.
