Grower's Choice AG140 140W Full Spectrum LED Grow Light

The number of units you can daisy chain depends on your input voltage. At 277V, you can connect up to 24 units on a single circuit. At higher voltages, capacity increases: 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.

Both spectrum options deliver full-phase coverage optimized for flowering. The 3K spectrum provides a balanced distribution ideal for general cultivation, while the red-enhanced option increases the ratio of red wavelengths (660-680nm) to further promote flower density and resin production. Both maintain the same 3.0 µmol/J efficacy and 420 µmol/s PPF output.

Yes, the AG140 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.

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 comes packaged in boxes of 8 units, making it efficient for larger installations while requiring only the accessories needed for your specific application.

The AG140 uses industry-standard 0-10V dimming control, allowing you to adjust light intensity from 0% to 100% using a compatible device like the Grower's Choice Master Controller. This enables you to optimize PAR levels for different growth stages, implement sunrise/sunset routines, or reduce intensity during transplanting and cloning with systems like the Pro Pod Cloning System. The dimming signal can be sent through the daisy chain connection, controlling all linked fixtures simultaneously.

With its 44.4-inch length and 420 µmol/s output, each AG140 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 results, consult your facility's specific canopy dimensions and target PPFD levels to determine appropriate spacing between fixtures.

The L90 rating means the fixture maintains at least 90% of its initial light output after 50,000 hours of operation. If you run the lights for 12 hours per day, this translates to over 11 years of use before reaching the L90 threshold. Even at 18 hours per day (common for vegetative growth), you'll achieve approximately 7.6 years of consistent, high-performance lighting covered under the 5-year warranty.

Absolutely. The AG140's compact profile (3.55" × 3.21" cross-section), linear design, and uniform VPD distribution make it ideal for vertical farming racks and multi-tier systems. The IP66 rating provides protection in the high-density, high-humidity conditions typical of vertical farms, while the daisy-chaining capability simplifies installation across multiple growing tiers. Its 140W power consumption also helps manage heat output in densely packed environments.
