Clones, same lights, same nutrients, same up potting, same amount of nutrients poured in, same schedule everything and a control group of the same clonesIf you aren't using clones, then don't bother.

You're the one with the brilliant hypothesis, you test it.You should try it dumbass
My prediction, if you are capable of pulling this off, is you will see a very small and statistically insignificant difference. Further you will incur other costs that will render it equipose. You can't do this with just 2 plants you need to work out how many you have to grow so it will be a viable experiment and not simply random chance. I suggest using a sample size and confidence interval calculator since I doubt you have the mathematics.
But hey just yell another insult then get angry enough to go prove me wrong.
