Phytotron is a facility used to grow plants under controlled conditions. It provides a controlled environment that allows researchers to manipulate and regulate various environmental factors such as temperature, humidity, light, and carbon dioxide levels. This controlled environment enables scientists to study plant growth, development, and responses to specific environmental conditions in a controlled and reproducible manner.

Phytotron facilities are commonly used in plant research, including studies on plant physiology, genetics, ecology, and agronomy. By controlling the environmental conditions, researchers can investigate the effects of specific factors on plant growth and development, simulate different climates or ecological conditions, and conduct experiments under controlled settings. This controlled environment is especially useful for studying plant responses to environmental stress, optimizing growth conditions for crop plants, and conducting experiments that require precise control over environmental variables.
