What Is Under-Canopy Lighting?

More Than Just
More Light.

It's a distribution strategy. Top lights flood the upper canopy — but create steep light gradients that leave lower buds in the dark. Under-canopy lighting puts photons exactly where they're needed most.

In a standard flowering room, your upper canopy absorbs most of the light. Lower leaves and buds become passengers — still consuming nutrients and space, but not contributing to yield or quality. That's a profit leak hiding in plain sight.

Under-canopy lighting converts those under-lit zones from passengers into producers. It's the same reason this approach has been studied across high-value horticulture crops for decades — the mechanism is straightforward and the results are real.

Not sure if it's right for your setup? That's exactly what the free call is for. Elliott will tell you honestly whether it makes sense for your operation.

SCL

Undercanopy/Subcanopy Lighting

Upward-facing bars placed near the base of the plant row. Raises PAR in the middle and basal canopy. The most common starting point for most grows.

ICL

Inter-Canopy Lighting

Fixtures positioned within the canopy at multiple heights. More targeted, more complex — and in controlled studies, it delivered the highest yield and secondary metabolite gains.

The Problem

Your Lower Canopy Is
Costing You Every Harvest.

Top-only lighting isn't a neutral choice. It's an active source of yield loss, quality variance, and missed revenue — that growers are solving right now with under-canopy supplementation.

Yield Left on the Table

Lower buds in deep shade turn into low-density larf, wasting valuable yield you can’t recover. This larf is then relegated to extraction, or else it becomes a huge drain on ROI during trimming.

Up to 35% yield increase documented

Inconsistent Potency

Light gradients cause chemical variation, making top and bottom buds differ in secondary metabolites and terpenes and harder to keep consistent.

>50% reduction in secondary metabolite variability documented

Margin Compression

Expanding canopy costs more, while under-canopy lighting improves yields and ROI without increasing your footprint.

Yield gains can exceed energy cost increase
The Evidence

What the Research
Actually Shows

These aren't manufacturer claims. They're from peer-reviewed controlled-environment cultivation studies comparing under-canopy strategies directly against top-lighting controls.

+25%

Dry Inflorescence Yield (SCL)

Subcanopy lighting increased flower yield by ~24.6% vs top lighting alone in a 2025 controlled medicinal cultivation study.

+30%

Dry Inflorescence Yield (ICL)

Inter-canopy lighting pushed yield gains to ~30% in the same study — the highest result across all treatment groups.

>50%

Reduction in Secondary Metabolite Variability

Batch-to-batch consistency improved dramatically. Critical for medical markets and any operation needing standardized output.

Energy Use vs. Yield Gain

SCL added lighting energy+13%
SCL yield increase+25%
ICL added lighting energy+23%
ICL yield increase+30%
Secondary metabolite variability reduction>50%
Terpene variability reduction>50%

The key insight: in documented trials, yield gains exceeded the energy cost increase — meaning more profit per kWh spent. Results are site and cultivar dependent. Elliott will help you assess what's realistic for your operation.

Rebates & Savings

We Handle the Rebates.
You Keep the Savings.

Utility rebate programs for horticultural LEDs are real, significant, and widely underutilized. We do the legwork — from pre-approval through documentation — so you don't leave money on the table.

🔍

Rebate Program Identification

We scan available utility and state programs for your region and equipment. Most growers don't know what they qualify for — we do.

📋

Pre-Approval Before You Buy

Most programs require pre-approval before installation. We handle the timing and paperwork so you don't accidentally disqualify yourself by moving too fast.

📄

Full Documentation Support

DLC listing printouts, PPF/PPE spec sheets, installation records — utilities ask for specific formats. We prepare it all, correctly, the first time.

DLC-Listed Fixtures Only

We only recommend fixtures on the DLC Horticulture Qualified Products List — the baseline requirement for most incentive programs and increasingly for state energy codes. If rebates are available for your operation, we recommend fixtures on the DLC.

PPE ≥ 2.5 µmol/J Standard

DLC V4.0 raised the minimum efficiency threshold. We spec only fixtures that meet or exceed it — which is also what utilities are starting to require for incentive eligibility. This can often be a difficult process for individual companies, but we do this all the time.

A fully managed rebate process. Concierge level.

From identifying what you qualify for, to pre-approval, to final documentation — we run the whole thing. You focus on the grow.

Same-day response most days. No obligation.

Real Program Examples
Colorado (Xcel Energy) Up to $0.70/W installed
Oregon (Energy Trust) $0.15/kWh, up to 50% of project cost
Washington (PSE) Up to $0.20/annual kWh saved
Illinois (Ameren) $0.15/kWh up to $350 per fixture, for significant savings on highly efficient fixtures

Program availability, amounts, and requirements vary by region and change over time. We verify your specific eligibility before you commit to anything.

What Growers Say

What Commercial Growers Say About Elliott's Expertise

Real results from professional cultivators who relied on Elliott for layout reviews, rebate guidance, and setup advice.

Layout Review
✓ Fixture spec issue flagged
Elliott flagged a fixture spec issue that would have disqualified us from the rebate program entirely. Saved us thousands before we even placed the order.
Rebate Guidance
✓ Pre-approval handled
We had no idea rebates even applied to under-canopy bars. Elliott walked us through the whole thing and handled the pre-approval. Total concierge.
Setup Advice
✓ Simplified inter-canopy plan
Straight shooter. Told us inter-canopy wasn't worth it for our room size. Steered us to a simpler setup that still hit our yield targets for less money.

Common Questions

Questions We Hear
Every Week

Yes — understanding it early saves costly mistakes later. You don't need to be an expert. That's what the call is for. Elliott will tell you if it makes sense for your stage of buildout, or if there are higher priorities to address first.
Peer-reviewed controlled-environment trials show roughly 20–35% increases in dry flower yield, depending on strategy and cultivar. Results are site-dependent. Elliott will give you a realistic estimate for your specific room — not a marketing number.
All the majors — Faven, Grower's Choice, Fohse, Mammoth, Craft Farmer and more. Elliott runs the numbers side by side: PPFD at canopy, µmol/J efficacy, fixture spacing, and total cost per square foot. You get the honest winner for your rooms, not the one with the best margin.
It does add lighting energy — roughly 13% for SCL and 23% for ICL in controlled studies. But yield gains exceeded the energy increase in those same trials. The ROI depends on your product value and operating costs. Elliott will help you run the math.
Yes — any additional lighting adds heat load. Your dehumidification and climate system needs to be recalibrated when you add under-canopy bars. We factor this into the recommendation so you're not caught off guard.
Potentially yes — but it depends on your utility, your project type, and whether your fixtures meet DLC listing and PPE requirements. We verify this before you buy anything and handle the pre-approval process on your behalf.
Almost always. Our volume purchasing relationships with top horticultural lighting brands means we access pricing that most growers can't get on their own. That discount comes straight to you — on top of any rebate savings we identify. We also offer wholesale and bulk distributor pricing on multi-unit under-canopy orders.
