THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are targeting lower branch development because your overhead lights cannot penetrate the dense foliage at the bottom.
  • You are investing in supplemental lighting because your current harvest has too much variance between top and bottom buds.
  • You are opting for sealed bars because your IPM spray routine would short out a standard supplemental light fixture.

What We Found

  • We found that the 3.0 efficiency rating keeps the bars cool enough to touch even after a 12 hour cycle.
  • The smooth exterior is significantly easier to wipe down than the ribbed bars we usually see on supplemental lights.
  • The integrated daisy chain is robust enough that we trust it in high humidity rooms with 17 units in a row.

What Users Say

  • Users who added these to their racks say they stopped discarding airy B-buds because the lower density improved.
  • Facilities that switched to this model say the IP66 seal finally ended the cycle of replacing water-damaged bars.
  • Growers report that the red enhanced spectrum was the missing piece for getting heavy yields from the bottom third.

Grower's Choice 120W Under Canopy Light Red Enhanced

Uneven canopy development and low-quality B-buds represent lost revenue in every grow cycle. The Grower's Choice Under Canopy Light Red Enhanced solves this problem by delivering targeted 3.0 red spectrum lighting to the middle and lower canopy zones, creating uniform VPD distribution from top to bottom. This precision approach increases flower density, improves overall quality, and eliminates waste from under-developed buds.

The Under Canopy Light Red Enhanced features an IP66-rated housing that withstands direct IPM sprays and irrigation exposure while maintaining easy cleaning protocols. The optimized red spectrum penetrates dense foliage to drive photosynthetic activity in traditionally shaded areas, resulting in measurable yield improvements across the entire plant structure. Power and data chaining through a single connection point eliminates cable clutter and simplifies installation in multi-light configurations, similar to setups used with the PFS Series Bar Lights.

This under canopy solution integrates seamlessly into existing lighting systems, providing supplemental photon delivery where conventional top-lighting, like the powerful Grower's Choice ROI-E720 or the Grower's Choice ROI-E900, cannot reach. The red enhanced spectrum specifically targets flower development pathways, converting previously unproductive lower growth into marketable flower mass. For commercial operations focused on maximizing canopy utilization and eliminating grade variability, the Under Canopy Light Red Enhanced delivers quantifiable results.

Red Enhanced 3.0 Spectrum optimized for deep canopy penetration and flower development

FAQs

How does under canopy lighting improve flower quality? +

The Under Canopy Light Red Enhanced delivers targeted photons to the middle and lower plant zones that typically remain shaded by top canopy growth. This additional light energy drives photosynthetic activity in previously underperforming areas, increasing flower density and cannabinoid production throughout the entire plant structure rather than just the top colas. For growers seeking a more balanced spectrum for all stages, the Full Spectrum Under Canopy Light offers a versatile alternative, while the Grower's Choice AG140 Red Enhanced provides a higher-wattage option for demanding setups.

What makes the red enhanced spectrum different from standard grow lights? +

The Red Enhanced spectrum is specifically optimized for deep canopy penetration and flower development. This targeted approach maximizes photosynthetic efficiency for bud production, a topic explored in our article on how the grow light spectrum influences cannabis growth, while minimizing wasted energy on wavelengths that don't penetrate dense foliage.

Can I use this light in high-humidity or wet environments? +

Yes, the IP66 rating provides complete protection against IPM spray applications and water jets. The sealed housing prevents moisture ingress while maintaining easy surface cleaning, making it ideal for commercial growing environments with regular foliar treatments and high-humidity flowering conditions.

How many lights can I connect together on one circuit? +

The Under Canopy Light Red Enhanced supports daisy chaining up to 17 units through the integrated power and data connections. At 120W per fixture, this allows up to 2,040W total load, which should be distributed appropriately across circuits to maintain safe operation and voltage stability.

Where should I position these lights for best results? +

Install the lights horizontally between plant rows or vertically along plant sides, positioning them 12-18 inches from the middle canopy zone. The goal is to illuminate the shaded areas beneath the top canopy but above the lowest growth that will be removed during lollipopping for optimal flower development throughout the plant.

Will this replace my main grow lights? +

No, the Under Canopy Light Red Enhanced is supplemental lighting designed to work alongside your primary overhead LED fixtures, such as the Grower's Choice ROI-FF 650W. It addresses the specific problem of light penetration in dense canopies rather than providing complete spectrum coverage, maximizing the efficiency of your existing lighting investment by eliminating waste in lower plant zones.

Can I dim these lights to control intensity? +

Yes, the AG-120 features 0-10V dimming capability, allowing you to adjust light intensity with a compatible grow light controller or the dedicated Grower's Choice Master Controller. This flexibility helps you optimize supplemental lighting levels throughout the growing cycle while managing power consumption and heat output in your grow space.

How long will these lights last before needing replacement? +

The Under Canopy Light Red Enhanced is rated for 50,000 hours at L90, meaning the fixture maintains 90% of its original light output even after 50,000 operating hours. Running 12 hours daily during flowering cycles, this translates to over 11 years of service life before any measurable decrease in performance, backed by a 5-year manufacturer warranty.
