Grower's Choice Full Spectrum Under Canopy Light

Grower's Choice Under Canopy Light Full Phase

Limited light penetration in dense canopies restricts photosynthetic potential across the entire plant structure, resulting in inconsistent development and reduced total yield. The Grower's Choice Under Canopy Light Full Phase addresses this challenge with versatile mounting options and full-spectrum output, functioning as top light, side light, under canopy, or intracanopy illumination. This 120W LED bar delivers uniform light distribution to previously shaded zones, promoting balanced growth across all cultivation stages, from initial phases supported by a vegetative LED grow light through flowering. For growers needing higher intensity, the Grower's Choice AG140 140W Full Spectrum LED offers a powerful alternative.

The AG-120LW features IP66-rated construction with heat-resistant materials that maintain performance integrity in high-humidity environments and direct exposure to foliar applications. The full-spectrum output supports complete photosynthetic processes throughout the growth cycle, eliminating the need to swap fixtures between stages. Integrated daisy chaining combines power and data connections through a single interface, allowing up to 17 units per chain while minimizing cable complexity in multi-light installations.

This multi-position lighting solution provides commercial and hobby growers with precision control over canopy illumination. The compact form factor and adjustable mounting system enable strategic placement in areas where conventional overhead fixtures like the Grower's Choice ROI-E720 or ROI-FF 650W cannot effectively deliver photons. For operations focused on maximizing canopy efficiency and eliminating light-deprived zones, the Under Canopy Light Full Phase delivers flexible, full-spectrum supplemental lighting with proven reliability.

FAQs

What makes this light different from the Red Enhanced version? +

The Full Phase model features full-spectrum white light that supports all growth stages from seedling through harvest, while the Red Enhanced version and the AG140 Red Enhanced are optimized specifically for flowering. This versatility makes the AG-120LW ideal for growers who want a single fixture that works throughout the entire growth cycle without needing to swap lights between vegetative and flowering phases.

Can I use this as my primary grow light? +

While the Under Canopy Light Full Phase can function as a top light in smaller setups, it's designed primarily as supplemental lighting to work alongside primary overhead LED fixtures such as the powerful ROI-E900 commercial grow light. Its multi-position mounting allows it to serve as side lighting, under canopy illumination, or intracanopy lighting to maximize light penetration in areas your main lights cannot effectively reach.

What mounting positions work best for different applications? +

For under canopy use, mount horizontally 12-18 inches below the main canopy to target middle growth zones. For side lighting, mount vertically along plant rows to illuminate lateral branches. As intracanopy lighting, position bars within the canopy structure itself to address deep shaded areas. The adjustable mounting system allows you to adapt placement as plants grow and canopy density changes.

Is the full-spectrum light suitable for seedlings and clones? +

Yes, the balanced full-spectrum output is ideal for early-stage plants. The 0-10V dimming capability allows you to reduce intensity for sensitive seedlings and clones, which can be started in a dedicated unit like the Pro Pod Cloning System, then gradually increase as plants mature. This single fixture eliminates the need for separate propagation lighting, simplifying your equipment requirements across all growth phases.

How does the IP66 rating benefit my grow operation? +

The IP66 rating provides complete protection against IPM spray applications, irrigation overspray, and high-humidity conditions. The sealed, heat-resistant construction prevents moisture damage while maintaining easy surface cleaning for sanitation protocols. This durability is essential for lights positioned within or below the canopy where exposure to water and foliar treatments is common.

How many lights do I need for my grow space? +

Supplemental lighting requirements depend on your primary light coverage, canopy density, and plant spacing. As a general guideline, position one bar every 2-3 feet along grow rows for under canopy applications, or one bar per vertical side for side lighting configurations. The 44.4-inch length works well in standard 4x4 or 4x8 grow spaces, complementing a primary fixture.

Can I connect these with other Grower's Choice lights? +

Yes, the AG-120LW supports daisy chaining up to 17 units, which can be centrally managed with the Grower's Choice LED Grow Light Master Controller. You can mix Full Phase (white spectrum) and Red Enhanced models in the same chain, allowing you to strategically position different spectrums where they're most beneficial. At 120W per fixture, plan your circuit loads accordingly to maintain safe operation.

What accessories do I need to get started? +

Power cords and daisy chain cables are sold separately to accommodate different installation requirements. You'll need mounting hardware appropriate for your chosen position (horizontal or vertical), a compatible 0-10V dimmer or one of many available grow light controllers, and standard 120-277V power supply. The adjustable mounting system works with common grow tent poles, wall mounts, or ceiling suspension hardware.
