The Grower's Choice ROI-E420 represents an incredible value for your dollar. This high efficiency 420 watt LED has an incredibly even three foot by three foot coverage area, but many grower's have shown great yields in a four by four foot space as well. Because of the advanced design, light is more evenly displaced over the canopy, you have less hotspots/coldspots and can mount the fixture closer to your plants without worries of burning or bleaching. This model features built in dimming settings but is also controllable with Grower's Choice Master Controllers and compatible with many other quality master controllers. The ROI series features Growers Choice 3K Full Spectrum with 660nm deep red (Osram diodes).
The ROI series LED system is passively cooled with absolutely no moving components and features a hinged center design making for easier shipping and installation. Each unit includes the ROI-420LED grow light, 120V connection cable, user manual and set of rope ratchets for mounting the fixture.
