I am starting to think HID's and LED's are like comparing apples to oranges in most ways, they both provide nourishment but I prefer apples.  LED's and HID's  put out different types of light so how can you compare them other than the end results, bud quality and yield and the variables for those are endless. 

I just finished a grow of Mandarin Cookies from clones under the HID's. Next grow by the time I flip to flower I will be using a LED so we shall see.
