Maximize flower density with the 3.07 µmol/J Grower’s Choice 120W under canopy light designed to power high-yield indoor cultivations.

120W under canopy light with 3.07 µmol/J efficacy, 371 µmol/s output, and IP66 rating. Red spectrum designed for lower bud development.

The Grower’s Choice Red Enhanced Under Canopy Light is engineered to bring light where it's often lost—beneath the canopy. Delivering 371 µmol/s at 3.07 µmol/J, this 120W fixture enhances flower quality, increases density, and eliminates weak B-buds by providing even VPD throughout the grow zone. Its IP66 rating means you can spray, irrigate, and clean without worry.

Optimized with a red-heavy spectrum and a slim 44.4" profile, it integrates seamlessly into high-performance setups. With daisy-chain support for up to 30 lights, this light boosts yield potential while reducing power waste and infrastructure clutter. It’s efficient, rugged, and made for serious cultivators.

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.

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.
