I would like to welcome Jonathan to the forums. I hope that we all can learn more from him and hopefully he can also learn some things from us!!.
Regarding pitcher size, it would be helpful if from now on, we measure from the bottom of the pitcher to the peristome (or mouth). Why?, because as you may all know that the lid moves up and down depending on the relative humidity. Therefore, a pitcher with an average size of 2-2.25 inches by the old method, in fact, it should measure 1.75-1.8 inches in reality.
The next target should be to compare the Julie Jones's clone with both the german and the hummer's giant!!. How??.
Well, genetic analysis would be the way to go.
