- Greenhouse temperatures are determined by environmental influences such as radiational cooling, wind, cloudy or stormy weather and sun exposure. Temperatures are closely watched and maintained according to plant needs by the grower. A Dollar Princess fuchsia plant thrives in a 59 F setting while a New Guinea impatiens would stop blossoming, according to the University of Minnesota Extension.
- The beginning night temperature for warm-season crops is 60 to 65 F and 10 degrees lower for cool crops with an average of 50 to 70 F settings. Daytime temperatures are 5 to 15 degrees warmer than the nighttime setting.
- Temperatures are maintained by the grower with a thermostat for the heating or cooling unit system. Fans, vents and light all influence the temperature in the structure.
