Thats excellent info D'andra and everyone else. I hope we can get a thorough description on TC of bananas from you in the future. I am also hoping for pictures.
I am going to use the winter to practice, so that I may have a load of plants this spring.
Interestingly, I found a publication on the internet from a 6th grader(!) who had a science-project about tissue culture of plants. He failed on all attempts, except the batch where he used PPM.
I am pretty sure I am no better than he is, and will probably use PPM.
