How to Propagate Patchouli Cuttings

I cut some large woody branches off the patchouli tree a few months ago. The cuttings are doing very good and I think I'll be moving them from the incubator area to a home of their own pretty soon.

I cut off mature branches that had already flowered. I stipped the leaves, dipped in rooting hormone, and stuck them in this pot. They get misted every 3 hours for two minutes via my drip irrigation system. They get full sun for a good 5 hours each day, then bright filtered sun the rest of the day. The new growth sprouted from the nodes. The root system is showing through the bottom hole of the pot.
