The GrowPros Solutions HM960 LED Grow Light is a high-performance horticultural lighting system designed for commercial indoor cultivation, hydroponic grow rooms, and greenhouse rack systems. Engineered specifically for 4 ft × 6 ft grow trays, this powerful 960-watt full-spectrum LED fixture provides balanced lighting that supports plant growth from the vegetative stage through flowering.

Built with a sun-like full-spectrum light enhanced with deep-red LEDs, the HM960 delivers optimal wavelengths for photosynthesis and crop development. This spectrum promotes stronger vegetative growth, improved flowering performance, and increased yields by closely replicating the natural light plants receive outdoors.

The fixture produces approximately 2600 µmol/s of PPF with an efficiency of about 2.7 µmol/J, providing strong canopy penetration and consistent PPFD distribution across the growing area. With around 4500 high-quality LED diodes, the system delivers powerful light output while remaining significantly more energy-efficient than traditional HID or HPS grow lights.

Designed for modern cultivation facilities, the HM960 includes 0–10V dimming control and compatibility with professional grow controllers such as the TrolMaster Hydro-X system. Growers can easily adjust light intensity or automate lighting schedules to match plant requirements throughout different growth stages.

The fixture features a foldable multi-bar design for easy installation and transport, along with RJ12 daisy-chain connectivity that allows multiple lights to be linked together for synchronized control across large grow rooms. With passive cooling, durable construction, and a long LED lifespan exceeding 54,000 hours, the HM960 offers reliable long-term performance for professional cultivation environments.
