Wish I could watch this video... I mean, I can but I don't have any sound so it's basically useless. I've tried quite a few times to root ceph "pullings". In constantly moist LFS, under lights, in domes, no domes, in water... result is always the same for me which is leaf death. I don't dare try it with a pitcher. Not sure what I am doing wrong but I suspect I just can't get enough of the base of the leaf. Although once I got it down all the way to the crown so not sure not much farther down I could have gotten it. *shrugs*
CP pullings/cuttings and me don't mix. I seem to have better luck damaging a root so a natural division comes up.
