Spectrum

The ROI-FV runs the GC-5KF spectrum — a blue-dominant 5000K output engineered specifically for vegetative growth. This spectrum drives tight internodal spacing, strong root development, and dense canopy structure without the red loading found in full-cycle fixtures.

FAQs

What is the ideal use for the ROI-FV light?+

The ROI-FV is specifically designed for the vegetative stages of plant growth. Its GC-5KF spectrum is perfect for establishing strong mother plants, rooting clones, and ensuring vigorous, healthy vegetative development before the flowering phase.

Can I control this light with an external controller?+

Yes. The ROI-FV supports both 0-10V and step dimming from 10% to 100%, making it fully compatible with most external lighting controllers. For seamless integration and advanced control, we recommend using the Grower's Choice Master Controller.

What is the difference between this and a full-spectrum light?+

The ROI-FV uses the GC-5KF spectrum, which is heavy in blue light to promote tight, dense vegetative growth. Full-spectrum lights, like the Grower's Choice ROI-E720, include more red light and are designed to take a plant from seedling through harvest.

How high should I hang the ROI-FV above my plants?+

The recommended mounting height is between 6 to 24 inches from the plant canopy. For younger plants and clones, start at the higher end of this range and gradually lower the light as the plants mature and can handle more intensity.

What does the 5K spectrum mean for my plants?+

A 5K (5000 Kelvin) spectrum is rich in blue wavelengths, which mimics the light of spring and early summer. This encourages strong root development, tight internodal spacing, and lush foliage, creating a solid structure for the plant to support future growth.
