Aeroponic propagators can be used to root cuttings of all sorts of plants. While you can't see what's going on below the soil or in the propagator, roots are slowly forming.

Some plants can take a couple of months to root, while others will root in a week’s time. For plants that like warm growing conditions, or if you’re starting cuttings in winter or in a cool part of your home, use a seedling heat mat under the rooting tray to speed things up.
