The Grower’s Choice ROI‑E900 stands as the powerhouse in its class – a wide-format, eight-bar LED fixture that consistently delivers a full 1,000 W of photon output (± 5%) with a maximum boost to 1,050 W when paired with the brand's external control systems. Emitting a rich GC-3K full-phase spectrum with deep red peaks at 660 nm and a high CRI (> 86), it’s engineered for strong penetration, dense canopy coverage, and vigorous flowering. With an impressive total PPF of 2,340 - 2,600 µmol/s and a system efficacy of approximately 2.6 µmol/J, the ROI‑E900 offers not only power but efficiency, potentially reducing energy and HVAC expenses by around 40% compared to legacy HID lighting. But if this lighting system is too powerful for your grow space, then take a look at the 10K 315W system, or the smaller 10K 1000W SE for better light management.
