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.

*All cords and accessories are sold separately.

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.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
