Growing dense, high-value flowers isn't only about what's happening at the top of the canopy. As plants fill out, the lower and inner bud sites get shaded out – and that's where our dual side under canopy lighting goes to work.
Available in four length and wattage combinations - 4ft under canopy lighting at 120W, 6ft under canopy lighting at 150W, 180W, or 200W, and 8ft under canopy lighting at 250W - so growers can match the fixture to their row width and plant density.
Products Features
Dual Side Design
Light is emitted from both sides of the fixture simultaneously, covering two planes of the canopy interior in a single pass - ideal for rows trained or trellised on both sides, like SCROG setups and trellis netting systems.
Full Spectrum Output
Built around a high proportion of red light with a supporting blue channel, tuned to support flower development rather than vegetative stretch - exactly what the lower canopy needs during bloom.
Waterproof IP66 Build
Sealed against moisture and dust for humid grow rooms - especially important for under canopy placement, where fixtures sit closer to irrigation lines, runoff, and higher humidity zones than top lighting does.
Daisy Chain Compatibility
Multiple units connect in sequence and run off a single controller, so a full row - or room - can be dimmed and scheduled together instead of managing each fixture individually.
Benefits for Your Cultivation
Increased Yield
Clients running this under canopy lighting for commercial cultivation report a consistent 20 to 25 percent increase in yield. This isn't coming from a handful of ideal rooms - it's the number that shows up again and again across different setups, because the extra yield comes from bud sites that were previously getting little to no usable light, not from pushing the top canopy harder.
Denser, Higher Grade Flower
The most noticeable change growers describe is at the bottom of the plant. Areas that used to finish as loose, low value larf or B-grade material develop into tighter, denser flower once they're actually receiving direct light instead of scattered spillover from above. For operations selling on flower grade, that shift alone can change the economics of a harvest.
Even Canopy Coverage
Because light comes from two sides instead of one, there's less of a shaded "back side" to the stem or bud site. Single side units light one plane well and leave the opposite side dim - dual side emission closes that gap, which shows up as more uniform bud development across the whole lower canopy rather than a lit side and a shaded side.

Where This Under Canopy Lighting Fits
This under canopy lighting (UCL) is built for under canopy lighting for cannabis cultivation and other dense flowering crops grown in rows or on trellis systems, including:
- Commercial cannabis rows with moderate to tight plant spacing
- SCROG and trellis netting setups where plants are trained on both sides of the fixture
- Vertical farming tiers where mid-layer canopies need supplemental light from more than one direction
- Retrofit installs in existing rooms where top lighting is already dialed in but lower canopy yield is underperforming
If your rows are wide enough that both sides of the fixture face open canopy rather than a wall or aisle, dual side emission is typically the better option - you're getting coverage on both faces of the plant without paying for light aimed at empty space.

FAQ
Q: Is dual side emission better than single side or 3 side under canopy lighting?
A: It depends on row width and plant training method. Single side units work well against a wall or aisle where only one face needs light. Three side units suit very dense, wide canopies needing maximum coverage. Dual side sits in between - ideal for standard rows where both sides of the fixture face live canopy.
Q: Can I run different wattage units on the same controller?
A: Yes, as long as the controller and daisy chain wiring support the combined load - our team can confirm compatible groupings based on your room layout.
Q: What length should I choose for my row spacing?
A: As a general guide, match fixture length to row length rather than row width - 4ft rows suit tighter spacing, while 6ft and 8ft rows suit standard to wide commercial bench layouts. Wattage within each length can then be adjusted to canopy density.
Q: Do I need a separate top light if I install under canopy lighting?
A: Yes - this fixture is designed as supplemental lighting for the lower and inner canopy, working alongside your existing top light rather than replacing it.
