Thanks again Mike. I must be on the right track then so that has pleased me. Still a long way to go but if this site is full of people like you if problems do pop up no doubt I will find help here.
You're welcome. There are a lot of happy to help people with a ton of knowledge. Have patience and provide as much info as you can if you need help. Also, you might consider starting a journal, it makes it easier for people to help and see all your work in one place if you need help. How to Make a Grow Journal
Yes you could do that, as the plant grows and you add soil the stem will turn to root. I believe the better option would be to wait till the soil is mostly dry and turn the pot upside down and take the root ball out then add soil to the bottom of the container, and then place the plant back in and fill in around the sides.
