An under canopy LED grow light with integrated air circulation delivering deep red spectrum to improve lower bud density and overall yield.

The GrowPros Under Canopy Light Model 5 is built for growers who are tired of larfy lowers and uneven bud development. Designed with an 80% deep red spectrum, this LED grow light targets the lower canopy where traditional top lighting falls short. By bringing focused energy under the canopy, it increases flower density and helps lower bud sites finish closer to the top tier.

What sets this unit apart is the integrated aluminum air circulation tube. This is not just a plant LED grow light, it is a combined light and airflow system. Mounted beneath the canopy, it moves air along the row while delivering optimized spectrum to shaded zones, eliminating the need for extra ducting that blocks light or disrupts layout. Available in 4ft and 8ft options, it is built for high-density flowering rooms running rolling benches or fixed tables.

Dual Function: Yield Support + Microclimate Control

In high-density canopy environments, the under-canopy tier is where both light levels and air movement drop off first. This system is built to address both at the same time:

  • Commercial-proven spectrum: Full-spectrum output with roughly 60% red content supports higher yields and helps lower flowers finish denser and larger.
  • Airflow through the canopy: The aluminum ventilation tube lets air from external fans move along the row and through the canopy across the whole grow layer, and can be paired with the Quetzalcoatl Air Circulation System from Grow Pros Solutions or other compatible inline/duct fans (fans sold separately) to keep airflow more even around the crop from top to lower flowers.

Aluminum Ventilation Tube, Built to Scale

Each unit uses a built-in aluminum ventilation tube, making the fixture part of the under-canopy air system, not just a light bar. Each fixture connects to the next using a rubber duct connector to create a continuous airflow path along the row.

  • Built-in aluminum ventilation tube for durability in demanding grow-room conditions
  • Rubber duct connector compatibility for easy multi-unit extension along rows
  • Compatible with multiple Grow Pros Solutions fan options to match different room layouts and airflow paths

Interconnect Cables and Power Cords

Additional components can be ordered separately since quantities will depend on the total number of lights and selected configurations.

Note also that the lights connect together without interconnecting cables. The interconnecting cables are only needed to create the U where you have 2 rows of lights on a single bench OR if you need a space (up to 4 feet) between under canopy lights.

See the above chart for limitations on how many lights can be connected on 1 power cable.
