FAQs

What is the ideal coverage area for this light?+

The VSFL6450 is optimized for a 4' x 4' coverage area during the flowering stage and a 5' x 5' area during the vegetative stage. It's a perfect match for tents like the Vivosun Grow Tent Pro 4' x 4'.

Can I control the VSFL6450 with my phone?+

Yes, you can. When connected to the Vivosun GrowHub E42A Controller (sold separately), you can remotely control dimming, scheduling, and other settings through the Vivosun app on your smartphone for complete automation.

What makes the full-spectrum light beneficial for my plants?+

A full spectrum, including UVA, deep red, and far-red light, mimics natural sunlight. This encourages vigorous growth, stronger plant structure, and increased production of terpenes and cannabinoids, ensuring you can use a single light from seed to harvest. To learn more, check out our guide to the best full-spectrum LED grow lights.

How many lights can I connect together?+

The VSFL6450 is designed for scalability. You can connect up to 160 individual units using the daisy-chain feature, allowing you to create a uniform lighting environment for large commercial grow operations.

What is the benefit of the detachable power supply?+

The detachable power supply can be mounted outside of your grow tent. This significantly reduces the heat load inside the grow space, making it easier to maintain optimal environmental conditions and extending the overall lifespan of the light.
