The Solar Storm 440 is a very powerful LED based grow light. It features 88 high power 5 watt LED emitters for a total nominal power of 440 watts (88 x 5). The Solar Storm 440 has two unique features: A switch to change the light spectrum from Veg to Bloom and supplemental built-in UV-B bulbs. Having the ability to switch your light fixture between Veg and Bloom allows for lush vegetative growth and power savings in Veg mode while maximizing intensity and delivering the best yield in Bloom mode. The Solar Storm 440 also features a unique supplemental UV-B mode which is essential to develop higher potency harvest. 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.
