The Growers Choice ROI-E680S is a full spectrum LED perfect for medium-sized indoor grow spaces. It uses the renowned 3K full PAR spectrum of Growers Choice, which makes it perfect for seasoned growers and beginners alike.
The ROI-E680S provides up to 40 percent savings in energy but can cover up to 25 square feet inside grow tents. With 680 watts of power, the ROI-E680S gives you a PAR efficiency of 2.6 umols/J.
If you have an existing lighting controller, chances are the ROI-E680S will be compatible with your current device. This LED set comes with onboard dimming, to help you simulate night and daytime environments. But if you want full control, you can spring for the Growers Choice Master Controller to set the light to switch on and off during particular times or conditions to protect your plants from heat damage.
The ROI-E680 has the same 3K Full PAR spectrum that comes standard for Growers Choice.
Get up to 40 percent energy savings without sacrificing light quality with the ROI-E680.
The ROI-E680 is compatible with most controllers in the market. But you get the full functionality when using the Growers Choice Master Lighting Controller.
Get the best supplement to your Growers Choice lighting system through the Master Controller.
It features a two-channel programmable module that gives you control over two (2) separate growing areas.
