Push more light through your canopy layers using this compact 4ft dual-channel fixture built for B-bud boost and consistent growth below the tops.

The GrowPros Solutions 4ft Under Canopy Light Model 3 is designed to provide supplemental light to the lower regions of plants in indoor cultivation environments by strategically placing it beneath the top canopy of plants. This ensures leaves and flowers below the canopy receive optimal light exposure by eliminating shady areas. Under Canopy Grow Lights' benefits include uniform light distribution, maximized yield, and denser flowers.

GrowPros Solutions' first-ever under-canopy grow lights dual channel is engineered to enhance the yield and color of lower flowers. These supplemental lights can significantly enlarge B-buds and C-buds, promoting better growth and development in areas that typically underperform.

Built with premium housing and glass lenses, the Cobra UCL Model 3 is a dual-channel LED grow light designed for growers who want full control. One channel focuses on UV and blue wavelengths to drive resin production and quality, while the second channel emphasizes red spectrum output for yield. This flexibility makes it ideal for craft operations aiming to fine-tune plant response through each stage.

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.
