1. A controlled-environment chamber or facility used for growing plants under precisely regulated conditions of light, temperature, humidity, and other factors for scientific research.
Usage: technical; scientific

Examples

• The researchers used a phytotron to study how different light wavelengths affect plant growth.
• In the phytotron, scientists can simulate various climate conditions to test crop resilience.
• The university's new phytotron allows botanists to conduct year-round experiments regardless of outdoor weather.
• Plants grown in the phytotron showed consistent results because all environmental variables were carefully controlled.
• The phytotron facility enabled the team to accelerate their breeding program by controlling photoperiod and temperature.
