Mars Hydro FC4000 EVO 320W Complete Grow Kit | 2.85μmol/J

Precision Control in Any Space

Every facility that tolerates inconsistent equipment tolerates inconsistent output — and inconsistent output is a cost that compounds silently across every cycle. Fixtures that degrade faster than their rated lifespan, ventilation components that were never sized to the light load, and environmental dead zones that no manual adjustment can fully correct: these are not minor inefficiencies. They are structural yield suppressors that accumulate across weeks and quarters. The enemy is not a single failed component — it is the operational friction of equipment that was never engineered to work together, forcing constant intervention where automation should be running the room.

After deployment, the production environment changes character entirely. The canopy receives uniform photon distribution from a bar-style array that eliminates the hot-spot geometry of single-point sources. The ventilation loop — sized and matched to the thermal load of the fixture — maintains stable air exchange without manual recalibration. The operator is no longer managing equipment; the equipment is managing the environment. Scheduling, airflow, and light intensity operate as an integrated system rather than a collection of independent variables, and the result is a repeatable output profile that compounds positively across every subsequent cycle.

The mechanism behind that outcome is a Samsung LM301H EVO diode array operating at 320W ±5%, delivering a photon efficacy of 2.85 µmol/J and a total PPF of 871 µmol/s at AC120V — output figures that position this fixture alongside premium-tier competitors at a substantially lower capital cost. The spectral architecture covers 650–665nm red, 2800K–3200K warm white, and 4800K–5000K cool white channels, providing the full photosynthetically active range required for both vegetative development and reproductive-phase production. The FC4000 EVO's passively cooled bar design eliminates fan-driven thermal management at the fixture level, reducing acoustic load and removing a mechanical failure point from the system. The included 4-inch iFresh inline fan and carbon filter are rated at 205 CFM and matched to the 48x24x71-inch tent enclosure, ensuring the ventilation circuit is not the limiting variable in environmental control. In practical terms, the FC4000 EVO Kit delivers 871 µmol/s PPF across a 4x2 production footprint at 320W with a maximum yield target of 3.5g/W.

Where This Belongs (and Doesn't)

Electrical and HVAC infrastructure must be assessed by a licensed professional prior to deployment. The FC4000 EVO Kit is rated at 320W ±5% and requires a properly grounded circuit capable of supporting the combined load of the LED fixture, inline fan, and any supplemental equipment. Duct routing and carbon filter placement should conform to facility ventilation codes applicable in your jurisdiction.

How It Works

The FC4000 EVO LED fixture operates on a bar-style diode array populated with Samsung LM301H EVO chips — the same diode generation used in premium-tier commercial fixtures — driven by a Mars Hydro driver at 320W ±5%. The bar configuration distributes photon output across the canopy plane rather than concentrating it at a central point, producing a more uniform PPFD map across the 48x24-inch footprint. Passive cooling at the fixture level means no internal fan, no moving parts in the light head, and no additional acoustic or thermal load introduced by the fixture itself. The physical dimensions of the light bar are 44x14x1.3 inches, designed to fit within the 48x24x71-inch tent structure with clearance for canopy management and vertical plant development.

Spectral output spans three defined channels: 650–665nm red for photosynthetic efficiency and reproductive-phase response, 2800K–3200K warm white for full-spectrum vegetative and transitional-phase coverage, and 4800K–5000K cool white for blue-range photon delivery supporting structural development and secondary metabolite expression. The combined output of 871 µmol/s PPF at AC120V at a photon efficacy of 2.85 µmol/J positions the fixture at the upper boundary of its wattage class. The ventilation subsystem — a 4-inch iFresh inline fan rated at 205 CFM paired with a matched 4-inch carbon filter — is connected via 4-inch ducting at 9 meters (25 feet of flex ducting included) and managed through the included speed controller, allowing airflow modulation without replacing hardware. The tent structure measures 48x24x71 inches and includes 2x7.5cm, 2x15cm, and 1x20cm vent ports, one 25x25cm mesh window, and a single front-access door, with a structural support capacity of 50kg/110lb for equipment mounting. In practical terms, the FC4000 EVO Kit delivers 871 µmol/s PPF and a 3.5g/W maximum yield target within a fully enclosed 4x2 production cell at 320W with a matched 205 CFM ventilation circuit.

Operator Field Notes

• Passive Cooling Verification: The FC4000 EVO runs no internal fan. Confirm ambient room temperature is within the operating range before deployment — passive thermal management depends on adequate air exchange at the room level, not just within the tent.
• Ventilation Sizing: The 4-inch iFresh fan at 205 CFM is matched to the 48x24x71-inch enclosure. If supplemental CO2 enrichment is added to the environment, airflow management will require recalibration — the included speed controller supports modulation without hardware replacement.
• Duct Routing: 25 feet of flex ducting is included. Plan duct routing before assembly — sharp bends in flex ducting reduce effective CFM and can create back-pressure against the inline fan.
• Controller Upgrade Path: The kit ships with a basic speed controller for the fan. Operators running multiple cells should evaluate the iConnect Smart Controller ($27.99) or iControl Smart Controller ($49.99) for centralized scheduling and dimming across daisy-chained fixtures.
• Structural Load Planning: The tent frame supports 50kg/110lb. Account for the combined weight of the carbon filter, ducting, clip fan, and any irrigation hardware before mounting — approach the rated capacity with margin, not at the limit.
• Grow Bag Placement: Four 5-gallon grow bags are included. The 50x50cm plant net is sized for the tent footprint. Position bags to maintain airflow clearance at the base of the canopy — the clip fan should be directed at the lower canopy, not the light bar.
