After years of research and in-the-field testing, Smart Grow Systems today announced the availability for the newest member of its commercial vertical farming system, the GOLDENi grow light series for propagation and flower. GOLDENi represents a breakthrough in LED grow light technology, surpassing all other horticultural grow lights – including currently available commercial LEDs, high pressure sodium (HPS) and high intensity discharge (HID) – in producing biomass of exceptional quality crops with substantially improved pound-per-light yields with the most efficient use of space and greatest reduction in power.
