There is a switch for blue lights. There is a switch for red lights. And there is a switch for both lights. For flowering which light red only or both?
You can use full illumination mode during flowering if you need the additional canopy penetration.
Many of our clients prefer this method as it's a little more forgiving. With only the red output we highly recommend LST or another growth management method.
Thanks very much for the purchase. We hope to work with you again in the future.
