Grower's Choice AG140 140W Red Enhanced LED Grow Light

Uneven canopy lighting leads to inconsistent flower development and wasted energy on lower-quality buds. The Grower's Choice AG140 Red Enhanced eliminates this problem by delivering uniform Vapor Pressure Deficit (VPD) distribution across your entire canopy, resulting in denser flowers and higher yields with 455 µmol/s photon output at just 140W.

The AG140 Red Enhanced features an R80 spectrum specifically engineered for maximum flower production, emphasizing the red wavelengths (660-680nm) that drive flower density and resin production. With an exceptional 3.25 µmol/J efficacy rating, this fixture delivers more photosynthetic power per watt than the standard Grower's Choice AG140 140W Full Spectrum LED Grow Light. The IP66-rated construction withstands harsh growing environments, resisting IPM sprays and irrigation exposure while remaining easy to clean and maintain.

Installation complexity is eliminated through intelligent design—single-connection power and data chaining allows up to 42 units to operate from one circuit at 480V, dramatically reducing wiring requirements and installation time. The AG140 Red Enhanced's compact 44.4" × 3.55" × 3.21" form factor and 4.85 lb weight make it ideal for both commercial facilities and space-conscious operations. Backed by a 5-year warranty and L90 50,000-hour lifespan, this fixture delivers professional-grade performance with long-term reliability.

Frequently Asked Questions

How many AG140 Red Enhanced units can I daisy chain together? +

The number of units you can daisy chain depends on your input voltage. At 120V, you can connect up to 10 units on a single circuit. At higher voltages, capacity increases: 19 units at 208V, 22 units at 240V, 24 units at 277V, 30 units at 347V, and up to 42 units at 480V. This single-connection system eliminates the need for complex wiring and additional electrical infrastructure.

What makes the R80 Red Enhanced spectrum different from full-phase options? +

The R80 Red Enhanced spectrum is specifically engineered for flowering stages, with an increased ratio of red wavelengths (660-680nm) that directly drive flower density, resin production, and cannabinoid development. This results in higher efficacy (3.25 µmol/J vs 3.0 µmol/J) and greater photon output (455 µmol/s vs 420 µmol/s) compared to full-phase options, making it ideal for dedicated flowering rooms or bloom-focused cultivation.

Can the AG140 Red Enhanced be used for all growth stages? +

While the AG140 Red Enhanced can technically be used throughout the entire cultivation cycle, it's optimized specifically for flowering and bloom stages where red wavelengths provide the most benefit. For vegetative growth, a full-phase spectrum like the Grower's Choice AG140 Full Spectrum or the dedicated ROI-FV Vegetative Light may provide better results. Many growers use full-phase fixtures for veg rooms and switch to Red Enhanced for dedicated flowering spaces.

Can the AG140 Red Enhanced withstand high-humidity environments? +

Yes, the AG140 Red Enhanced features an IP66 rating, providing complete protection against dust ingress and powerful water jets from any direction. This rating ensures the fixture can withstand IPM foliar sprays, irrigation overspray, and high-humidity growing environments without compromising performance. The sealed design also makes cleaning and maintenance straightforward.

Do I need to purchase additional cords or accessories? +

Yes, power cords and mounting accessories are sold separately. This allows you to customize your setup based on your facility's specific requirements, including voltage configuration and mounting preferences. The AG140 Red Enhanced comes packaged in boxes of 8 units, making it efficient for larger installations while requiring only the accessories needed for your specific application.

How does the 0-10V dimming system work? +

The AG140 Red Enhanced uses industry-standard 0-10V dimming control, allowing you to adjust light intensity from 0% to 100% using a compatible controller like the Grower's Choice LED Grow Light Master Controller. This enables you to optimize PAR levels for different flowering stages, implement sunrise/sunset routines, or reduce intensity during stress periods. The dimming signal can be sent through the daisy chain connection, controlling all linked fixtures simultaneously.

What coverage area should I expect from each fixture? +

With its 44.4-inch length and 455 µmol/s output, each AG140 Red Enhanced is designed for dense, linear coverage ideal for bench-style or vertical farming systems. The uniform VPD distribution technology ensures consistent PAR across the fixture's footprint. For optimal flowering results, consult your facility's specific canopy dimensions and target PPFD levels (typically 800-1200 µmol/m²/s for flowering) to determine appropriate spacing between fixtures.

How does the higher efficacy translate to energy savings? +

The AG140 Red Enhanced's 3.25 µmol/J efficacy means it produces approximately 8% more usable light per watt compared to 3.0 µmol/J fixtures. Over a typical 12-hour flowering light cycle, this translates to significant energy savings while delivering 455 µmol/s of photosynthetic photon output. The enhanced red spectrum also means more of that light energy is in wavelengths that directly drive flower production, maximizing your return on investment.
