I'd recommend watching the video. Not convinced she has no conception of bonsai, nor that she is lying.
I have to question (having watched the video) whether process is overwhelming result.
The woman in the video, who appears to have tons of experience, also has an interest in growing seedlings in tiny tiny pots. Though I think the process is interesting, the result (a sickly, leggy tree) is not (at least to me). After all, if the goal of bonsai is to create the sense of an old tree in nature, how does growing a seedling in a tiny pot accomplish this?
You could argue... well some amazing trees in nature are amazing because they grew in very hostile environments from the moment they germinated. But I don't see the connection. You don't have to make your trees suffer adverse conditions. You just want them to LOOK like they did. This woman is spending years and years growing plants in harsh conditions... when the end result is that they look like what I could accomplish with a two year seedling and some wire. Oh and my tree would be green. If you have to TELL someone your little seedling is 25 years old, haven't you already failed?
