Dial in explosive flowering performance with 1950 PPF output, a 3.0 µmol/J efficiency rating, and a spectrum built to fuel dense, terpene-rich yields.

The Growers Choice ROI-FF 650W is built for serious cultivators who demand precision lighting for high-yield flower rooms. Consuming 650W while delivering a powerful 1950 PPF output, this fixture pushes an impressive 3.0 µmol/J efficiency—giving your plants maximum usable light for explosive growth. Engineered with state-of-the-art diodes and drivers, the ROI-FF 650W’s 3K spectrum is optimized for flowering, ensuring dense buds, enhanced terpene profiles, and superior cannabinoid production.

Is the ROI-FF 650W Energy-Efficient?

At 3.0 µmol/J, this LED grow light outshines standard DE HPS systems (1.7–2.1 µmol/J) by delivering more usable photons per watt. This translates to lower electricity bills, reduced HVAC strain, and bigger harvests. If you want higher yields without higher costs, the ROI-FF 650W is a no-brainer for commercial flower operations.
