Grower's Choice ROI-FV-320 320W Vegetative LED Grow Light

The Grower's Choice ROI-FV-320 320W Vegetative LED Grow Light is a commercial LED fixture engineered specifically for propagation rooms, clone production, mother plants, and dedicated vegetative cultivation. Rather than utilizing a bloom-focused spectrum, the ROI-FV-320 features Grower's Choice's proprietary GC-5K vegetative spectrum, developed to maximize healthy plant structure, vigorous branching, and rapid canopy development without excessive red loading.

Operating at 320 watts, the ROI-FV-320 delivers 928 µmol/s of Photosynthetic Photon Flux (PPF) while achieving an efficacy of 2.9 µmol/J. This combination provides commercial growers with high photon efficiency, allowing more usable light to reach the canopy while helping reduce electrical operating costs compared to traditional HID vegetative lighting.

The dedicated GC-5K spectrum has been engineered specifically for vegetative environments where plant structure is the priority. It promotes compact internodal spacing, aggressive root development, strong lateral branching, and healthy mother stock that is well prepared for flowering after transplant. By minimizing unnecessary red loading during vegetative growth, the ROI-FV-320 helps create stronger, more uniform plants throughout commercial production cycles.

Its six-bar LED architecture distributes light evenly across the growing area, producing highly uniform canopy coverage while minimizing central hotspots. This broad light distribution supports consistent vegetative growth across benches, rolling tables, and commercial propagation rooms, allowing every plant to receive more balanced photon exposure.

Designed for professional cultivation facilities, the ROI-FV-320 operates across an exceptionally wide 108V to 480V AC input range, making it compatible with nearly every commercial electrical infrastructure. The fixture includes both integrated onboard dimming and 0–10V external dimming, allowing seamless integration with centralized lighting controllers and facility automation systems.

The fixture utilizes passive cooling with no internal fans, eliminating moving components that require maintenance while providing quiet operation and long-term reliability. Its IP66-rated enclosure offers excellent protection against dust and moisture commonly found in commercial cultivation environments, making it suitable for demanding indoor grow facilities.

Measuring 45 x 44 x 4.2 inches and weighing only 20 pounds (8.7 kg), the ROI-FV-320 remains easy to install while providing professional-grade coverage. It is designed for hanging heights between 6 and 24 inches above the canopy depending on crop stage and lighting intensity. The fixture is rated for an L90 lifespan exceeding 54,000 hours, meaning it is designed to maintain at least 90% of its original light output throughout its rated service life.

Whether you're building a dedicated propagation room, expanding mother plant production, or upgrading a commercial vegetative facility, the Grower's Choice ROI-FV-320 delivers professional efficiency, uniform canopy coverage, advanced dimming capabilities, and a spectrum engineered specifically for exceptional vegetative performance.

GC-5K Vegetative Spectrum

Unlike traditional full-spectrum grow lights, the ROI-FV-320 utilizes Grower's Choice's dedicated GC-5K vegetative spectrum, specifically engineered for propagation, clone production, mother plants, and vegetative development.

This carefully tuned spectrum promotes compact growth, strong branching, healthy root development, and vigorous canopy formation while avoiding excessive red wavelengths that are more beneficial during flowering. The result is stronger, healthier plants that transition efficiently into bloom.

Commercial 320W Performance

The ROI-FV-320 consumes 320 watts while producing an impressive 928 µmol/s PPF with an efficacy rating of 2.9 µmol/J.

This balance of high photon output and energy efficiency allows commercial growers to maximize vegetative growth while reducing electrical costs across large cultivation facilities.

Uniform Six-Bar Light Distribution

The fixture's commercial multi-bar design distributes photons evenly across the growing area rather than concentrating light beneath a central board.

This wide distribution minimizes hotspots, improves PPFD uniformity, and helps produce more consistent plant growth throughout propagation benches, mother rooms, and vegetative canopies.

Commercial-Grade Electrical Compatibility

The ROI-FV-320 is designed specifically for professional cultivation facilities with an ultra-wide 108–480V AC input range, allowing it to operate across virtually all commercial electrical systems.

Integrated onboard dimming and 0–10V external dimming provide flexible light intensity control while allowing seamless integration with compatible environmental controllers and facility automation platforms.

Passive Cooling & IP66 Protection

The ROI-FV-320 uses a passive cooling system with no internal fans, reducing maintenance requirements while providing quiet, dependable operation in demanding cultivation environments.

Its sealed IP66-rated construction protects the fixture against dust and moisture, making it well suited for commercial propagation rooms, vegetative facilities, and controlled-environment agriculture.

Long Service Life

The fixture is rated for an L90 lifespan exceeding 54,000 hours, meaning it is designed to maintain at least 90% of its original light output throughout its rated operating life.

This long service life helps reduce maintenance requirements, minimize replacement frequency, and deliver consistent lighting performance across commercial cultivation cycles.
