Not really; what I do have is an aquarium. I've water-rooted past cuttings in a bit of used fish water. The extra nutrients seem to help keep the plant alive as it roots.
Googling around, it seems like crotons are kind of picky about rooting. I may have to actually pick up some hormone. =/

Edit: Those past cuttings were mostly tough stuff, like Pothos, Wandering Jew, and a single half-successful attempt at some Soleirolia soleirolii. This would be my first shot at rooting a croton.
