This is a great time lapse of our Black Dog LED indoor grow lights against HID lights. These indoor hydroponic lights were from our very first line with 3-watt LEDs (which have since been replaced with newer and better LED technologies), but this video still shows the overall power and results of a Black Dog LED light. As you can see in the video, the roots are much denser and healthier under the LED light. In the experiment you could see the true differences between the traditional HID (Metal Halide and High Pressure Sodium) lights and the Black Dog LED grow lights.
