Shop Mars Hydro Canada →Most grow light guides are written for American buyers. Canadian growers face a different set of decisions: which brands actually ship to Canada reliably, what Canadian pricing looks like after currency conversion and duty, which lights are on Amazon.ca with Prime shipping, and whether warranty claims get honoured without shipping your light to a warehouse in California or China.
This guide is built specifically for Canada. Every light reviewed here ships reliably to Canadian addresses, has a warranty honoured for Canadian customers, and has been evaluated against Canadian pricing. Where we have a head-to-head comparison, we've gone beyond spec sheets and looked at real PPFD maps, coverage uniformity, and what Canadian growers actually report.
We've also been transparent about our affiliate relationship with Mars Hydro — they have a Canadian store and we earn a commission when you buy through our links. That said, where Spider Farmer is the better choice, we say so. Where AC Infinity makes sense, we say that too. The goal is a guide you can actually trust.

What Specs Actually Matter — and What's Marketing
The grow light market is full of inflated numbers and misleading claims. Here's a plain-language breakdown of what to look at and what to ignore.
✅ True Wattage (Draw Watts) — the only wattage that counts
The only wattage that matters is how many watts the light actually pulls from the wall — called draw watts, true watts, or actual power consumption. A "1000W equivalent" LED that draws 100W is a 100W light. Full stop. Every reputable brand publishes true draw watts — if a manufacturer only lists "equivalent" wattage, that's a red flag. All lights in this guide are listed by true draw watts.
✅ Efficacy (µmol/J) — the single most important spec
Efficacy measures how much usable light (photons in the PAR range) a fixture produces per watt of electricity consumed. It's expressed in micromoles per joule (µmol/J). This is the single number that most accurately predicts how much your plants will grow per dollar of electricity.
Efficacy benchmarks:
Below 2.0 µmol/J — outdated technology, avoid
2.0–2.4 µmol/J — entry-level modern LED, acceptable
2.5–2.7 µmol/J — good, worth buying (TS-1000, TSW-2000 range)
2.8–2.9 µmol/J — excellent (FC-3000, SE-3000 range)
3.0+ µmol/J — top tier (FC-6500 range)
✅ Diode Quality — what's actually inside the light
Samsung LM301B and LM301H diodes are the industry benchmark for white-spectrum LEDs. Samsung LM301H Evo is the newest generation — used in the FC-6500. Osram 660nm reds provide far-red output for flowering enhancement. Lights using these diodes run cooler, degrade more slowly over years of use, and produce more stable output. If a manufacturer doesn't specify diode brands, assume generic chips.
✅ PPFD Maps — how even is the coverage?
PPFD (Photosynthetic Photon Flux Density) measures how many photons hit your canopy per square metre per second (µmol/m²/s). A published PPFD map shows the distribution across the full footprint — a good light covers the canopy evenly, not just a hot spot in the middle. Bar-style LEDs like the FC-3000 generally produce better PPFD uniformity across a 4×4 than square panel designs. If a manufacturer doesn't publish a PPFD map, they don't want you to know the numbers.
❌ "Equivalent" wattage — meaningless
Ignore any wattage number labelled as "equivalent," "replaces," or compared to HPS/HID. These numbers have no standardised definition and are used purely for marketing. Only true draw watts matter.
❌ "Full spectrum" — not a differentiator
Every modern white-spectrum LED from a reputable brand is "full spectrum." It's a marketing term, not a technical specification. What matters is the actual diode specs and whether specific wavelengths (like 660nm reds or far-red) are present — not the label "full spectrum."
Buying a Grow Light in Canada — What's Different
🇨🇦 Use the Canadian store
Mars Hydro has a dedicated Canadian store at marshydroled.ca. Buying here avoids import duties, gets faster shipping, and means your warranty is handled in Canada. Buying from mars-hydro.com (the US site) ships from the US and can trigger import duties that push the total cost well above the Canadian price.
📦 Amazon.ca vs direct
Both Mars Hydro and Spider Farmer are available on Amazon.ca with Prime shipping. Amazon.ca is convenient for returns and fast delivery. The direct Canadian store (marshydroled.ca) sometimes has better pricing, especially with discount code ZEE for 3% off. Check both before buying — prices vary.
🔌 Voltage — not an issue
Mars Hydro and Spider Farmer lights operate on 100–240V and work fine on Canadian 120V circuits. No adapters needed. Larger lights (FC-4800, FC-6500) can also run on 240V for slightly better efficiency — most residential Canadian setups use 120V and that's perfectly fine.
🛡️ Warranty in Canada
Mars Hydro and Spider Farmer both honour warranties for Canadian customers without requiring you to ship to China. Mars Hydro's FC series carries a 5-year warranty. Spider Farmer's SE series carries a 3-year warranty. Keep your purchase receipt — warranty claims require proof of purchase.
💰 Use code ZEE
Canadian buyers can use discount code ZEE at marshydroled.ca for 3% off any Mars Hydro order. On a $420 FC-3000 that's ~$12.60 off. On a $1,200+ FC-6500 it's $36+. The link marshydroled.ca/discount/ZEE applies it automatically at checkout.
🏪 Local hydro stores
Major Canadian cities have dedicated hydroponics retailers that carry Mars Hydro and other brands in stock. You can inspect the product in person before buying and get staff advice. Prices are sometimes slightly higher than online but the ability to physically check the light and get same-day is often worth it for larger purchases.

Mars Hydro
Mars Hydro is the strongest all-round choice for Canadian growers in 2026. They have a dedicated Canadian store (marshydroled.ca), consistent Amazon.ca availability with Prime shipping, and the widest range of lights covering every tent size from 2×2 to 6×6+. The FC series (FC-3000, FC-4800, FC-6500) represents some of the best value-per-watt LEDs available in Canada at their respective price points.
✅ Strengths
- Dedicated Canadian store — marshydroled.ca
- Consistent Amazon.ca availability with Prime
- Best range — 2×2 to 6×6 covered
- FC series bar design — excellent PPFD uniformity
- 5-year warranty on FC series
- Code ZEE — 3% off all orders
- Bundle options (tent + light) at discount
❌ Weaknesses
- SE series slightly lower efficacy than Spider Farmer equivalent
- TS series (square panels) less uniform than bar designs
- No app/ecosystem integration (unlike AC Infinity)
Spider Farmer
Spider Farmer is a genuine competitor to Mars Hydro and edges it out on raw efficacy in several head-to-head comparisons. The SE series (SE-2000, SE-3000, SE-5000) uses Samsung LM301H diodes and consistently achieves 2.7–2.9 µmol/J — matching or slightly exceeding the comparable Mars Hydro models. Canadian availability has improved significantly — the SE series is well-stocked on Amazon.ca in 2026. No Canadian-specific discount code available.
✅ Strengths
- Slightly higher efficacy on SE series
- Samsung LM301H diodes (newer than LM301B)
- Competitive pricing — often slightly cheaper than Mars Hydro equivalent
- Strong Amazon.ca availability on SE series
- 3-year warranty honoured in Canada
❌ Weaknesses
- No dedicated Canadian store
- Amazon.ca stock less consistent than Mars Hydro
- No Canadian discount code available
- Narrower product range at the high end
AC Infinity IONBOARD
AC Infinity is best known for fans and climate control equipment, and their IONBOARD LED series is worth considering if you're already running their ecosystem. Native integration with the CONTROLLER app means you can schedule sunrise/sunset dimming, set stage-based intensity, and manage everything from one app alongside your fans and humidity control. The raw light output is slightly below Mars Hydro and Spider Farmer at the same price point, but the automation value is real for growers who want a fully integrated setup.
✅ Best if you want
- App-controlled everything in one ecosystem
- Sunrise/sunset dimming automation
- Stage-based intensity scheduling
- Already running AC Infinity fans
❌ Not ideal if you want
- Maximum yield per dollar
- Highest efficacy for the price
- Simple manual dimmer setup
Head-to-Head: Mars Hydro TSW-2000 vs Spider Farmer SF-2000 — Best 3×3 LED in Canada
The 3×3 tent category is one of the most popular sizes for Canadian home growers — big enough for meaningful yield, small enough to fit in a closet or spare room. These two lights are the main contenders in Canada in 2026.
| Mars Hydro TSW-2000 | Spider Farmer SF-2000 | |
|---|---|---|
| True wattage | 300W ✓ | 200W |
| Efficacy | 2.6 µmol/J | 2.7 µmol/J ✓ |
| Diodes | Samsung LM301B | Samsung LM301B ✓ |
| Coverage | 3×3 – 4×4 ✓ | 2×4 – 3×3 |
| CAD price | ~$260 ✓ | ~$290 |
| Amazon.ca | ✅ Prime ✓ | ✅ |
| Warranty | 3 years | 3 years |
| Discount available | Code ZEE — 3% off ✓ | None |
Buy the TSW-2000 if:
- You want to cover a full 3×3 canopy edge-to-edge
- You might expand to a 4×4 tent later
- Budget matters — it's $30 cheaper
- You want to use code ZEE for extra 3% off
- You value Amazon Prime delivery
Buy the SF-2000 if:
- You have a strict 3×3 and don't need 4×4 coverage
- Efficacy per watt is your priority over total output
- You find it on sale below the TSW-2000 price
Our verdict: For most Canadian 3×3 growers the TSW-2000 is the better buy. The extra 100W of true output covers the canopy more thoroughly, it's cheaper, and code ZEE saves an additional 3% at marshydroled.ca. The SF-2000's efficacy advantage is real but marginal — in a 3×3 tent you'll get better results from more photons than marginally more efficient photons. If they're the same price, the SF-2000 is a fair choice; if the TSW-2000 is cheaper (which it usually is), buy that.
Head-to-Head: Mars Hydro FC-3000 vs Spider Farmer SE-3000 — Best 4×4 LED in Canada
The 4×4 tent is the most popular size for Canadian home growers, and this matchup is the most hotly debated in the grow light community. Both lights use bar-style designs with top-tier diodes and compete closely on almost every spec. Here's the detailed breakdown.
| Mars Hydro FC-3000 | Spider Farmer SE-3000 | |
|---|---|---|
| True wattage | 300W | 300W |
| Efficacy | 2.85 µmol/J | 2.9 µmol/J ✓ |
| Diodes | Samsung LM301B + Osram | Samsung LM301H ✓ |
| PPFD uniformity | Excellent — foldable bars ✓ | Very good — bar design |
| CAD price | ~$420 | ~$400 ✓ |
| Canadian store | marshydroled.ca ✓ | Amazon.ca only |
| Amazon.ca availability | Consistent ✓ | Variable — watch stock |
| Warranty | 5 years ✓ | 3 years |
| Discount available | Code ZEE — 3% off ✓ | None |
Buy the FC-3000 if:
- You want the most consistent PPFD coverage edge-to-edge
- You value a 5-year warranty over 3
- You want a Canadian store and direct support
- Stock availability matters — FC-3000 is always in stock
- You want to use code ZEE for 3% off
Buy the SE-3000 if:
- You can confirm it's in stock on Amazon.ca
- You find it noticeably cheaper than the FC-3000
- You want the absolute highest efficacy spec for a 4×4
- The 3-year warranty is sufficient for your needs
Our verdict: This is genuinely close. The SE-3000 has a real efficacy edge and is often slightly cheaper. The FC-3000 has better PPFD uniformity, a longer warranty, consistent Canadian availability, and a dedicated Canadian store with discount code ZEE. For most Canadian growers, the FC-3000 is the safer, more reliable choice — especially when you factor in code ZEE narrowing the price gap. If you see the SE-3000 clearly in stock and noticeably cheaper, it's a fair buy. But if they're within $20–30 of each other, the FC-3000's advantages tip the balance.

Shop Mars Hydro Canada →Grow Lights to Avoid in Canada
Not everything on Amazon.ca is worth buying. Avoid these categories regardless of price:
Blurple lights (purple/pink panels) — popular before 2019, dramatically less efficient than modern white-spectrum LEDs. If it glows purple, skip it regardless of the price or the wattage claim.
"1000W equivalent" budget panels — a $60 LED claiming 1000W equivalent that draws 100W is a 100W light. The "equivalent" claim has no meaning. Always check true draw watts.
Lights without published PPFD maps — reputable brands publish PPFD distribution maps. If a manufacturer doesn't, they're hiding the numbers. That's a hard pass.
No-name brands with no Canadian warranty — if the warranty support is a Gmail address and the brand has no Canadian presence, you're buying disposable hardware. The lights from Mars Hydro and Spider Farmer cost more for a reason — they're still running after 3–5 years.
Buying from amazon.com (US) instead of amazon.ca — lights ordered from Amazon's US store can trigger import duties on delivery that push the real cost well above the Canadian market price. Always buy through Amazon.ca or marshydroled.ca for Canadian orders.

Frequently Asked Questions
Mars Hydro vs Spider Farmer — which is better for Canadian growers?
Both are excellent. Mars Hydro has a dedicated Canadian store (marshydroled.ca), more consistent Canadian availability, a 5-year warranty on the FC series, and discount code ZEE for 3% off. Spider Farmer has a slight efficacy edge on paper in the 4×4 category. For most Canadian growers, Mars Hydro wins on availability and value. If Spider Farmer is clearly in stock and cheaper, it's a genuine alternative.
FC-3000 vs SE-3000 — which should I buy?
The SE-3000 has a slight efficacy edge (2.9 vs 2.85 µmol/J) and is usually slightly cheaper. The FC-3000 has better PPFD uniformity, a 5-year warranty, and consistent Canadian availability with code ZEE for 3% off. Within $20–30 of each other, the FC-3000's advantages tip the balance. If the SE-3000 is clearly cheaper and confirmed in stock, it's a fair buy.
Is there a Mars Hydro discount code for Canada?
Yes — use code ZEE at marshydroled.ca for 3% off any order. The link applies it automatically at checkout.
TSW-2000 vs SF-2000 for a 3×3 tent — which wins?
The TSW-2000 wins for most Canadian 3×3 growers. It has 100W more true output, covers the canopy more thoroughly, and is cheaper — especially with code ZEE. The SF-2000's efficacy edge is real but the extra output from the TSW-2000 more than compensates in practice.
