Mars Hydro FC 3000 300W Complete Indoor Grow Kit | 2.85 μmol/J

Precision Control in Any Space

Every cycle lost to uneven canopy coverage is a cycle that cannot be recovered. When the fixture above your canopy delivers inconsistent photon density — hot zones that stress the top tier, dead zones that stall lateral branching — the damage compounds silently across every run. Manual dimming adjustments made by eye introduce operator-to-operator variance that makes benchmarking impossible. Fixtures without scalable control architecture force you to treat every room as an isolated problem rather than a replicable system. The cost is not just one underperforming harvest; it is the inability to diagnose why results differ between runs, between operators, and between rooms.

After deployment, the operational picture changes. The canopy receives uniform photon delivery across the full 3×3 ft core footprint, cycle after cycle, without lamp degradation curves to compensate for. Intensity is dialed from 10% to 100% through a single dimmer knob, giving the operator precise stage-appropriate control without external hardware. Multiple units synchronize through daisy-chain RJ11 cabling, so a multi-light room runs as a single coordinated system rather than a collection of independent fixtures. Bluetooth connectivity through the Mars Hydro mobile app extends scheduling and intensity management beyond the physical room, reducing the labor overhead of manual light checks during active production cycles.

The mechanism behind that operational consistency is a Samsung LM301B diode array running at 300W ±5% across a 22.8" × 20.4" × 3.2" fixture body, producing 854 µmol/s PPF at 2.85 µmol/J PPE — a photon-per-watt ratio that positions this fixture competitively against units sold at significantly higher price points. Input voltage range of 100–277V at 50/60 Hz means the FC 3000 integrates into existing electrical infrastructure without step-down transformers or dedicated circuits in most licensed facility configurations. At 120V the draw is 2.535A; at 240V it is 1.238A; at 277V it is 1.082A. The fixture weighs 9 lb (4.37 kg), and the included suspension kit, dimming cable, driver support brackets, and hanging kit allow for rapid deployment without sourcing additional mounting hardware. In practical terms, the FC 3000 Kit delivers 854 µmol/s PPF across a 3×3 ft core canopy at 300W draw with a 2.85 µmol/J PPE rating using Samsung LM301B diodes.

Where This Belongs (and Doesn't)

Electrical installation, circuit load calculations, and HVAC integration should be performed by a licensed electrician and mechanical contractor. Cannafull Spectrum Solutions provides fixture specifications for planning purposes only and does not provide installation services.

How It Works

The FC 3000 is built around a Samsung LM301B diode array — the same chip series used in fixtures sold at significantly higher price points across the licensed cultivation market. At 300W ±5% draw, the array produces 854 µmol/s PPF at a photosynthetic photon efficacy of 2.85 µmol/J. The fixture operates across a universal input voltage range of 100–277V at 50/60 Hz, drawing 2.535A at 120V, 1.238A at 240V, and 1.082A at 277V. This voltage flexibility eliminates the need for dedicated step-down infrastructure in most licensed facility electrical environments.

The full-spectrum output is delivered through a passively cooled fixture body measuring 22.8" × 20.4" × 3.2" (58 × 52 × 8.2 cm) and weighing 9 lb (4.37 kg). Passive thermal management removes the mechanical failure point introduced by active cooling fans, reducing maintenance intervention requirements over the fixture's operational lifespan. Intensity is adjustable from 10% to 100% via an onboard dimmer knob, allowing stage-appropriate output calibration — lower intensity during early vegetative phases, full output during peak flower demand — without external controllers.

Control scalability is delivered through RJ11 daisy-chain connectivity, allowing multiple FC 3000 units to be linked and managed as a unified system. Bluetooth integration with the Mars Hydro mobile app extends control to remote scheduling and intensity adjustment, reducing the need for physical access to each fixture during active production. The kit ships complete with suspension kit, dimming cable, driver support brackets, and hanging kit, enabling deployment without sourcing additional mounting hardware. In practical terms, the FC 3000 Kit delivers 854 µmol/s PPF at 2.85 µmol/J PPE across a 3×3 ft core canopy footprint from a 9 lb passively cooled fixture body drawing 300W at universal voltage.

Commercial Assurance

• Warranty: Up to 5 years per manufacturer terms — review current warranty documentation at point of purchase for full coverage conditions.
• Diode Sourcing: Samsung LM301B LED chips — the same diode series specified in premium-tier fixtures at a significantly lower system cost.
• Domestic Fulfillment: Ships from 10 U.S. warehouse locations, reducing transit time and freight exposure for licensed facilities across the contiguous 48 states.
• Manufacturer Track Record: 16 years of focused indoor cultivation technology development behind the FC series platform.
• Authorized Channel: Cannafull Spectrum Solutions is a factory-authorized dealer. Warranty claims are processed through the authorized channel, not gray-market resellers.

System Integration

• Daisy-Chain Expansion: RJ11 cable connectivity allows multiple FC 3000 units to be linked into a single control network — scale from one fixture to a full room array without adding controllers.
• Voltage Compatibility: Universal 100–277V input at 50/60 Hz integrates directly into standard U.S. licensed facility electrical infrastructure at 120V (2.535A), 240V (1.238A), or 277V (1.082A).
• Mobile Control: Bluetooth connectivity with the Mars Hydro app enables remote intensity scheduling, reducing manual intervention labor during active production cycles.
• Passive Thermal Architecture: No active cooling components means no fan motor maintenance, no airflow obstruction risk, and no additional acoustic load in climate-controlled grow environments.
• Kit-Complete Deployment: Suspension kit, dimming cable, driver support brackets, and hanging kit are included — no supplemental hardware procurement required for standard single-fixture installation.

Operator Field Notes

• Voltage Selection: At 277V the FC 3000 draws only 1.082A — operators on 277V commercial circuits can run significantly more fixtures per circuit breaker compared to 120V deployments (2.535A per fixture). Plan circuit loading accordingly before finalizing room layout.
• Daisy-Chain Limit: Source data confirms RJ11 daisy-chain capability but does not specify a maximum unit count per chain. Confirm the per-chain limit with the manufacturer or your authorized dealer before designing multi-fixture control runs.
• Dimming Protocol: The onboard dimmer knob provides 10%–100% intensity control. No PWM frequency or advanced protocol data (0–10V, DALI) is specified in source data. Operators requiring protocol-based integration with third-party environmental controllers should verify compatibility before purchase.
• Flower Zone Sizing: The FC 3000's commercial flower coverage is 2.5×2.5 ft (75×75 cm). Operators planning 3×3 ft flower rooms should account for the reduced coverage footprint during dense canopy phases and adjust fixture count or mounting height accordingly.
• Kit Completeness: The included suspension kit, dimming cable, driver support brackets, and hanging kit cover standard single-fixture installation. Multi-fixture daisy-chain runs may require additional RJ11 cables not included in the base kit — confirm cable lengths needed before deployment.
• Warranty Documentation: The manufacturer provides up to 5 years of warranty coverage. Retain purchase documentation and register the fixture per manufacturer instructions to ensure warranty claims are processed through the authorized channel.
