I don't know much about it, and what I do is based on faded memory, but my recollection is that they are a nightmare to grow!
Orchids needing humid rainforest conditions
Pods harvested have to them be processed to stop all vegetative growth, and at that point they have no Vanilla flavour, that is achieved by curing them which I think required wrapping them in bundles in the dark, but unwrapping them every day and exposing them to the sun for something like an hour only before wrapping them up again. I seem to remember that had to be repeated for ages? but maybe its gained something in the remembering and it was only a few weeks - still way too much Faff for me!!!
