The GrowPros Solutions Under Canopy Light with Air Circulation is an innovative horticultural lighting system designed to illuminate lower canopy zones while improving airflow within dense plant structures. By combining targeted under-canopy lighting with built-in air circulation, this fixture helps eliminate shaded areas beneath the plant canopy while also maintaining a healthier microclimate around lower leaves and buds.

Engineered with an 80% deep-red spectrum (around 660 nm), the fixture is optimized to support flowering and biomass production. Deep-red light penetrates dense foliage and stimulates photosynthesis in lower plant sections, encouraging stronger bud development, increased flower density, and more consistent crop growth from top to bottom.

The system is available in two lengths—4 ft and 8 ft—to accommodate different grow layouts. The 4-foot model typically operates around 125W and produces approximately 350 µmol/s of PPF, while the 8-foot model delivers about 250W with roughly 700 µmol/s of PPF, providing wider coverage and deeper canopy penetration for larger cultivation areas.

Beyond lighting performance, the integrated air circulation feature improves airflow beneath the canopy, helping reduce humidity pockets and supporting healthier plant environments. This dual-function design improves plant transpiration, strengthens stems, and helps prevent issues related to stagnant air in dense cultivation setups.

Built for commercial indoor farming environments, the fixture features a slim aluminum housing, passive cooling design, and durable construction suitable for humid grow rooms and greenhouse operations. It supports wide input voltage (120–277V), controller compatibility, and daisy-chain connectivity, allowing multiple units to be installed efficiently across large cultivation spaces.
