The Grower’s Choice ROI‑E680 LED grow light is a collaborative creation between Grower’s Choice and TSL Horti‑Tech that delivers commercial-grade performance in a compact footprint. Consuming 680 W, it produces an impressive 1,700 - 1,770 µmol/s of PPF with around 2.5 - 2.6 µmol/J efficacy, giving growers nearly 40 % energy and HVAC savings compared to traditional HID fixtures. The fixture spans roughly 42 - 46″ square and stands just 2.4 - 3.2″ high, allowing easy installation in low‑clearance spaces while still providing uniform coverage for a 4×4 ft veg area and up to 5×5 ft during bloom. 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.
