You did a great job. Did you put the cuttings in a little greenhouse? Kevin Corralito suggested putting the cutting in a small 4 oz cut then putting a 12 oz clear cup over the top to form a little greenhouse. The soil is saturated til it runs out the bottom holes in the small cup. I kept mine in there until I could see little roots in the smaller cup. Gradually let in outside dryer air until they came out completely. It sounds like your method is much simpler and has really good results. How did you do yours? Nor did mine ever form tubers.
