ROI-E420 Performance

The ROI-E420 is ideal for vegetative growth, providing an impressive 1090 umols/s of PPF. When hung 12″ above a 5′ x 5′ canopy, your plants will see an average of over 600 umols/m^2/s ensuring optimal PPFD throughout veg. Using the built in 0-10V dimming port with your own control system or pairing this light with the Growers Choice Master Controller will provide you the ability to fine tune the output to balance energy utilization throughout the entire growth cycle. This also eliminates the need for you having to raise the lights, simply hang the ROI-E420 high above your plants at the beginning of vegging, and let them grow up and into the light.

Energy Efficient Cultivation

Boasting an impressive 2.6 umols/J of efficiency, the Growers Choice ROI-E480 will keep your energy costs low and your plants healthy. Using the Growers Choice Master Controller to optimize the light output for your particular application can further reduce your energy expenses. In some cases, growers have seen a 40% reduction in HVAC and electricity costs by using the Growers Choice ROI-E420 compared to other LED lighting fixtures.
