I agree, and you know best 2 grows out of 3 might be necessary to really test each light to the fullest, one grow with 2 clones isn't set in stone absolute undeniably hands down guaranteed winner of all there is to be and known as full truth on the matter, there still a few variables that could use some tweaking, certain strains may prefer the HLG over the HGL and vice versa, certain environmental factors may have played a role here or there, and well all I'm saying is one grow isn't an absolute final answer and there is still need for further trial runs to know which light is without a doubt superior over the other.
And also I agree
@growingforfun we need hybridway to post his full wattage used to know what to calculate together to get us our gram per watt total for each light setup he/she ran this run, it's still a little unclear what to think of the numbers without this data. Thanks & Cheers.
