Genetic mutation + potency loss = up to 25% difference. Compare a fourth gen clone to the seedling mother and you'll believe. Look it up! Agreed, peer reviewed science will be great.......you do it, I have precious little time. Check it out bro, my Aurora Ultra strain I made between 2000-2003, I'm still cloning the exact original mother plant that I made in 2003 and the only thing that's changed is the clones now all ways have tight staggered internodes instead of the straight across internodes with the little buds. The potency is exactly the same as the mother plant was, two hits and you HAVE TO LAY DOWN. So I also disagree. TOAST
