- Mapping container opening size to internal climate conditions
- Clear glass allows the full spectrum of light needed for photosynthesis
- Narrow-necked jars trap significant moisture

- Identifying the best glass quality for plant light absorption
- Identifying signs that a container is trapping too much or too little moisture for a specific plant type
