UNDER CANOPY LIGHTING

Unlock the Potential of Your Lower Canopy

Increase A-grade buds, reduce trim waste, and boost overall crop value with Fluence’s under canopy lighting solutions.

  • Boost A-Grade Flower from 37% to 50%
  • Reduce Trim Waste & Increase ROI
  • Optimize Performance Across All Facility Types

Advanced Under Canopy Performance for Commercial Cannabis

Toplighting alone cannot fully penetrate dense cannabis canopies, leaving lower bud sites underdeveloped and turning potential yield into trim waste. Fluence under canopy LED lights deliver high-efficiency photons directly to shaded lower parts of the plants, creating a new photosynthetically active plane that transforms grade distribution, uniformity, and overall crop value. With proven results on large scale commercial operations, under canopy lighting represents the next evolution in distributed lighting strategy for professional grow lights.

Why Under Canopy Lighting?

  • Proven Results: Increase A-grade buds from 37% to 50% while reducing trim waste from 35% to 26%
  • High Efficacy: Deliver photons where they’re needed most for exceptional energy efficiency and maximizing yields
  • Distributed Lighting Strategy: Redistribute photons without overdriving toplights, supporting enhanced flowering and bud development
  • Flexible Applications: Works across single-tier grows, multi-tier vertical farms, and greenhouses for optimal plant growth

Understanding Under Canopy Lighting

What is under canopy lighting?

Under canopy lighting is a purpose-built LED system installed beneath the cannabis canopy, delivering high-efficiency photons directly to shaded lower bud sites. This stimulates photosynthesis in tissue typically underdeveloped due to light loss at the top of the canopy, maximizing the productive parts of the plants.

Why is it better than toplighting alone?

Because toplighting alone cannot penetrate dense cannabis canopies. Under canopy LED lights increase A-grade flower ratios, reduce trim waste, improve bud uniformity, and minimize morphology stress such as foxtailing or re-vegetation by redistributing photons instead of overdriving top lights. This approach supports enhanced flowering and bud development throughout the entire canopy.

When should you use it?

Use under canopy grow lights when canopy density limits light penetration, especially in mid to late flowering, in premium flower markets demanding higher top-grade fractions, when maximizing yields per square foot, in HPS to LED transition environments, and in greenhouses and indoor grow lights facilities with limited toplight electrical headroom.

Where should it be installed?

Under canopy LED systems work in single-tier indoor grows, multi-tier vertical farms, and greenhouses. Typically installed 8-12 inches above the substrate for optimal performance on both large scale and smaller operations.
