Temperature and Humidity Control Capabilities and Limitations of a Spaceflight Plant Growth Chamber

Environmentally sealed or isolated life sciences experiments such as plant growth chambers or animal habitats often require active temperature and humidity control. The interaction between the temperature and humidity control system, and performance limitations are shown based on experimental data using a small spaceflight plant growth chamber. Limited availability of electric power, and the chosen control system implementation constrain the obtainable temperature and humidity setpoint combinations.
