I did it in akadama and in potting soil. Akadama was best, better draining, less chance of damping off. I might ad pumice this time. For starting the seeds it is not that important as long as humidity is correct, it depends on the climate. For the seedling cuttings I used akadama (good rooting, medium growth), perlite (medium roots, vigorous growth), potting soil (lesser root division, good growth), akadama-pumice (good roots, good compact growth). Medium needs to be able to dry out in spring fall and winter, but adequate watering in summer. What medium you use depends on your climate, wintering and watering possibilities. Keep in mind that the depth of the container dictates where the moisture will be. Put akadama in a shallow container and it will stay wet for 2 days. Put it in a Cascade pot and the top cm's will be dry in no time.
