Description

 

Under canopy LED grow lights Feature

 

The under-canopy LED grow light is built specifically for the spots where most lamps never reach - the lower part of your canopy. Whether you grow cannabis, tomatoes, strawberries, leafy greens, or anything with a dense canopy, this bar helps bring those shaded sections back to life.

High Light Efficiency

 

When plants sit under a thick canopy, they're starving for photons.
This under-canopy grow light delivers more usable light, with a PPE of 2.8–2.9 μmol/J, meaning electrical energy is converted to plant-usable light very efficiently. That extra light on the lower branches helps them photosynthesize properly rather than just survive.

Many of our growers tell us they see a 10–20% bump in total yield once they add under-canopy lighting during flowering.

IP65 Waterproof - Built for Real Grow Rooms

 

Everything under the canopy gets messy: humidity, runoff water, foliar sprays, pesticides-you name it.
The under-canopy light is rated IP65, meaning it handles all of that without complaints. You can wipe it down and spray around it, and it keeps running safely and steadily.

Durable, High-Transparency Lampshade

 

We use a high-grade transparent cover that lets more than 90% of the light pass through.
It doesn't yellow, warp, or crack even after long hours of heat and humidity. This means your plants always get clean, even light across the whole bar.

Easy Installation Anywhere Under the Canopy

 

You can hang it from suspension wires or fix it to brackets at the bottom of the canopy-whichever works better for your setup.
The slim bar design slips right into tight plant rows without taking up space or blocking airflow.

It's built for growers who want something simple: Mount it → plug it in → forget about it.

Custom Spectrum Options

 

Different crops and grow rooms need different light mixes.
We can tailor the spectrum depending on:

• plant species
• greenhouse or indoor use
• growth stage
• desired cannabinoid/terpene improvement
• color ratio preferences (e.g., red/blue/IR/UV)

Just tell our team what you're growing and what you're trying to optimize - we'll match the best spectrum for you.

How Under-Canopy Lighting Works

 

Top lights can only do so much.
Once the canopy gets thick, the lower leaves barely see light, which leads to:

• weak photosynthesis
• yellowing leaves
• early leaf drop
• small or undeveloped buds
• wasted nutrients and lower ROI

 

Under-canopy lighting brings light directly to the shaded areas so the whole plant can work evenly from top to bottom.

Growers notice:
✔ healthier lower branches
✔ stronger bud development
✔ better uniformity
✔ higher-quality flowers
✔ less defoliation needed

Comparison: With vs Without Under-Canopy Light

 

Aspect Without With
Lower Canopy Light Almost none Bright enough to stay productive
Photosynthesis Weak Strong from top to bottom
Bud Size Small, airy Denser, more uniform
Plant Structure Uneven Balanced, easier to train
Leaf Yellowing Happens early Greatly reduced
Mold Risk Higher (dark + humid) Lower (more airflow + light)
Resource Efficiency Wasted nutrients Full plant utilization
ROI Lower Higher yield, higher value
