FAQs

What is the ideal coverage area for the ROI-E720?+

The ROI-E720 is designed to provide optimal coverage for a 5' x 5' area during the flowering stage. For the vegetative stage, it can effectively cover a larger area of up to 7' x 7'.

Can I control this light with my existing controller?+

Yes, the ROI-E720 uses a standard 0-10V dimming protocol, making it compatible with most lighting controllers on the market. For the most advanced features, such as sunrise/sunset simulation and high-temperature auto-dimming, we recommend using the dedicated Grower's Choice Master Controller.

How does this model compare to other Grower's Choice lights?+

The ROI-E720 is a high-power flagship model designed for maximum yield in a 5'x5' area. For smaller spaces like a 4'x4' tent, the Grower's Choice ROI-E420 offers the same great technology in a more compact size. For larger commercial applications, consider the even more powerful ROI-E900.

What is the recommended mounting height?+

For best results, 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 light requirements.

How can I learn more about optimizing light for my plants?+

Understanding the light spectrum is key to maximizing plant health and yield. We recommend reading our in-depth guide on how the grow light spectrum influences cannabis growth for detailed information and tips.
