Kind LED Grow Lights was formed and founded by age old growers who have utilized traditional High Intensity Discharge lighting to attain amazing yields and top quality results harvest after harvest, for decades on end. When LEDs first entered the scene many years ago, the folks at Kind LED were skeptical to say the least. The promise of cutting the electrical consumption in half, producing next to no heat, AND maintaining the same amazing quality cultivated from HIDs sounded too good to be true.....and unfortunately it was....at least in the beginning. While resistant to buying into the new Light Emitting Diode revolution, and hesitant to disrupt their already successful setups, Kind LED still had its curiosity piqued. The potential for a light that could deliver all that was being promised would change the face of indoor gardening forever. The upside of this possibility was so great, the implications so huge, that Kind LED could not just look the other way. Instead they asked the questions: Why are these lights falling short? How come the yields arent what they should be? How can we build upon, amplify, and make viable this new lighting concept? The need to learn the answers to these questions and more, along with the burning desire to make the LED promise a reality, lead the Kind LED crew on an obsessive path to learn everything there was to know about this new technology, to build upon the existing designs, and to actually develop a light that lived up to the hype. After years of research and development, what they developed was even more. The K3 & K5 Series LED Grow Lights are the culmination of all their hard work and dedication, and are nothing less than works of art.
