If you can clone using aero cloning device, why not? As long as the stem is moist and it has rooting hormone on it, as well as incorporating other basic cloning techniques, should get one through.
I would never do it that way, but to each his own. Hydroton must be the most difficult way for me to clone, therefor I use easier methods already mentioned. Before I were to attempt hydroton clones, I would try a aero-cloner, rock-wool, and type of rapid rooter, peat pots, some non-fertilized soil in a small cup that I can add a little B-1 and kelp solution to, and even that white **** that is trying to compete with rock-wool. I guess that is why I would never attempt to use hydroton. And that's what I love about this plant.....it is so damn versatile!!!
