I am sure this has been asked so many times but I really couldn't find a guide etc here and seen most people mention HID and CFL lights.
Having never grown before I am I thresher in LED as they seem to use much less power and produce a lot less heat but cost more.
Can they really match the old HID lamps? What are the downsides of LED? I'm not sure why I havnt seen more people use them here.
