Hi Kate, you got hooked!
I'm excited for and your new adventure in adeniums. I started out pretty much the way you have started. And did a lot of experimenting in growing adeniums.
Your 3-year-old pictured above looks like a fairly healthy specimen. In prep for re-potting into fresh new media, I have some suggestions. Carefully remove plant from its container, spray-wash the soil off of the roots, and trim any overly-long fine roots.
To re-pot, fill a shallow, wide pot with new media to about halfway, and place plant on top spreading out the roots. Then fill in more media on top of roots to about one inch below the previous soil line--exposing more of the fat caudex. (If you would like a canopy form, prune the main stem at the same time of repotting; cut to half the height it is now.) Water the media thoroughly with starter/transplant solution and place the newly potted plant in a protected area. Do not water again for a week or until media is almost dry; allow plant roots to settle in and begin growing new roots. Continue watering with starter solution for another two weeks. Then place plant in a light shade area for several weeks before exposing to full sun.
In another post you had asked about slow-release fertilizer. Mixing the pearls in the new potting media before planting is a good idea. It will take a couple of weeks for the pearls to begin releasing nutrients and by then the new fine roots will be able to take up the fertilizer.
Kate, please feel free to ask if you have questions or need clarification.
Other members here may offer further helpful suggestions to you based on their own experiences.
