Yes, it works the same way, but potting soil holds more water than coco cubes, so the main risk is rot. Keep the soil lightly moist, not soggy, and don't water again until the top starts to dry. Wet soil under a dome is the classic way to get stem rot or mold. A light mix with plenty of perlite (about 30%) works best, and a rooting gel or powder helps. Your humidity plan is good, just watch the condensation: if drops run down the walls all day, open it a bit earlier. Keep the light gentle (about 100-200 PPFD) and 18-24h. Roots usually show in 7-14 days. Skip all feed until the roots are out, since fresh soil already has enough.
