FAQ

Which power cord should I choose? Match the circuit you will plug into: 120V (NEMA 5-15P), 240V (NEMA 6-15P) or 277V (NEMA L7-15P). Need a longer run? M-25 adapter cords are available in 1, 8 and 15 ft lengths.

Do you offer a 480V version? Yes, a high-voltage version is available for commercial projects. Email info@growerschoice.ag for pricing.

Can I dim it?Yes. Use any 0-10V controller, such as the Grower's Choice Master Controller, or adjust it directly with the on-board dimmer.

Is it a good fit for veg rooms? The 3K Full Phase spectrum works through the whole cycle, but for dedicated veg and mother rooms we recommend the ROI-FV 2.0 (320) with its 5K vegetative spectrum.

What's the warranty? 5 years.
