AG140 Series is a commercial LED grow light delivering uniform canopy VPD improved flower density and reliable performance for large scale indoor production.

AG140 Full Phase and AG140 Red Enhanced are precision LED grow lights engineered to correct canopy VPD and eliminate low-quality bud production.

The AG140 LED grow light solution serious growers use when canopy consistency becomes the limiting factor. The AG140 platform is designed to balance Vapor Pressure Deficit across the entire canopy, driving uniform transpiration and eliminating underdeveloped lower buds. Available as Full Phase 3K or Red Enhanced, this full-spectrum LED grow light supports aggressive flowering, tighter node stacking, and improved density in high-intensity indoor rooms. Ideal for rolling benches, vertical racks, and dense commercial layouts running soil or hydro.

Smart investment comes from solving problems that other fixtures ignore. By stabilizing canopy VPD, this LED indoor plant grow light improves flower consistency top to bottom while reducing wasted energy on non-productive biomass. IP66 waterproof construction allows washdowns, IPM sprays, and high-humidity operation without failure. Single connection power and data chaining reduces wiring clutter and labor time, making this plant grow light LED easy to scale across large facilities.

Energy-efficient performance focuses on usable plant response rather than raw wattage. As a modern grow light full spectrum LED system, AG140 delivers significantly more effective canopy level performance than legacy HPS fixtures operating around 1.3 to 2.1 µmol per joule. The result is better flower quality, reduced HVAC load, and a more controlled production environment.

Interconnect Cables and Power Cords

Additional components can be ordered separately since quantities will depend on the total number of lights and selected configurations.

Note also that the lights connect together without interconnecting cables. The interconnecting cables are only needed to create the U where you have 2 rows of lights on a single bench OR if you need a space (up to 4 feet) between under canopy lights.

See the above chart for limitations on how many lights can be connected to 1 power cable.

Is the Grower's Choice Under Canopy Light energy-efficient?

Absolutely. With a 3.07 µmol/J efficacy, this light performs better than most toplights and blows HPS efficiency out of the water. It delivers more usable light per watt exactly where your plants need it—low in the canopy—helping you produce higher quality buds without increasing your electricity bill.

Features

FAQs

Do under canopy LED lights really improve bud growth?

Yes. Under canopy lights give lower bud sites direct light, preventing popcorn buds and boosting density, potency, and overall yields with more uniform bud growth.

How much yield increase can I expect from under canopy lighting?

Growers typically see 10–30% higher yields. LED under canopy lights help shaded branches produce dense, top-quality buds instead of small, underdeveloped ones.

Are under canopy LED lights energy efficient and cost effective?

Yes. With efficiencies of 2.5–3.0 μmol/J, these lights use little power while significantly boosting production, making them a high ROI investment for indoor bud growers.

How do I install under canopy grow lights in my setup?

Under canopy LED bars are slim and easy to mount. They can be placed on the floor, clipped to tent poles, or daisy-chained along racks, fitting hobby tents or commercial grows.
