Get to Know the Growers Choice ROI-FV 350W 4 x 4 Veg LED Light

The Growers Choice ROI-FV 350W is built for growers who demand high-performance veg lighting without wasting power. Designed specifically for commercial cultivation, this 350W LED grow light delivers an impressive 1050 PPF output at 2.9 µmol/J efficiency, giving your plants exactly what they need for vigorous vegetative growth. With its optimized 5K spectrum, this fixture enhances root development, canopy density, and overall plant structure—setting the foundation for massive yields in flower.

Is the ROI-FV 350W Energy-Efficient?

Absolutely. With an efficiency rating of 2.9 µmol/J, the ROI-FV 350W crushes outdated HPS fixtures (1.3–2.1 µmol/J) in energy savings and light output. More usable photons per watt means lower electricity bills, reduced heat output, and a higher return on investment. If you're serious about scaling your grow while cutting costs, this is the light you want in your veg space.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
