it usually takes 2-4 weeks to get roots. but you can look for the leaves to maintain a healthy look and to see if the leaves start to respond more vigorously to the light and start to reach outwards toward the light. also reduce water misting on the leaves after about 5-7 days so the cuttings have to try to find water in your soil or medium. hope this helps and i'm sure othere will also give you great advice. take care
