Yo bro, I use party cups! I mix a 50 - 50 mixture of peat moss and pearllite to fill them up. Once the plant has a trunk, it can be moved to a larger pot. You will be surprised at how big they can get in a party cup.
Transplanting is eas, if you need to do it... Make sure the soil is a little damp, it will slide out better. Hold the stem inbetween two fingers and hold your hand their to support the soil. Turn it upside down, and tap it out. Place in new soil and you are done.
