We took a drive to a couple of small towns outside of the city. We stopped at a commercial orchid grower's facitily and took a tour.
The growers seal the seed pods inside these glass bottles with only the air that exists in the bottle. They create their own micro-climate. There are 100's of orchids growing inside each bottle. When they reach a certain size, they transfer them to pots. It takes several years to complete the process.
