hi paul,
i have some experience with cloning, generally just taking a cutting, dipping it in rooting solution and planting it will not work.
usually you will need to keep the cutting in a humidity and temp controlled environment until roots form (usually 2-3 weeks) or they will just dry out
its tricky until you get the hang of it, too much heat and humidity and mold will form, too little and they will dry out
i usually try to keep them around 75-85% humidity and around 75-85 degrees
feel free to ask questions, good luck, let us know how it goes
phil
