FAQs

What is the ideal coverage area for the ROI-E900?+

The ROI-E900 is specifically designed to provide intense, uniform coverage over a 4' x 5' area during the flowering stage. For vegetative growth, it can effectively cover a larger space of up to 6' x 6'.

Can I control this light with a master controller?+

Yes, absolutely. The ROI-E900 is equipped with an RJ14 port and is fully compatible with most 0-10V lighting controllers. For seamless integration and advanced features like sunrise/sunset simulation, we recommend using the Grower's Choice Master Controller.

How does the ROI-E900 compare to other models like the ROI-E720?+

While the excellent ROI-E720 is a powerful fixture for standard 4'x4' or 5'x5' spaces, the ROI-E900 is the next step up. It offers significantly more power (1000W vs 720W) and a wider bar design, making it the superior choice for larger, commercial-style 4'x5' or 5'x5' grow areas where maximum intensity and coverage are critical.

How high should I hang the light above my plants?+

For optimal performance, the fixture should be mounted at a minimum height of 6 inches above the plant canopy. You can adjust the height based on your plant's growth stage and response to the light's intensity.

What is the benefit of the GC-3K Full Phase spectrum?+

The GC-3K Full Phase spectrum is a proprietary blend of diodes that provides a balanced light output, mimicking natural sunlight. It's rich in red and blue wavelengths essential for photosynthesis and includes a green spectrum for deeper canopy penetration. You can learn more about how light spectrum influences plant growth in our detailed guide.

Where can I find setup tips and performance data for this light?+

For a complete analysis of this fixture's performance, including PAR maps, efficiency data, and detailed setup recommendations, we highly recommend reading our in-depth Grower's Choice ROI-E900 review.
