What is the ideal daytime temperature range for interior plants?

The ideal daytime temperature range for interior plants is generally considered to be between 70-80 degrees Fahrenheit. This range provides optimal conditions for photosynthesis, growth, and overall health for many common houseplants. At this temperature, plants can effectively absorb light and engage in metabolic processes without experiencing stress or slowed growth.

Temperatures in this range promote favorable humidity levels and allow for adequate transpiration, which is the process through which plants regulate water and nutrient uptake. It also supports the development of robust foliage and flowering in many species, enhancing their aesthetic and health.

While some interior plants can tolerate lower or higher temperatures, the 70-80 degrees Fahrenheit range serves as a comfortable environment for a wide variety of common houseplants, making it a practical recommendation for indoor gardening.
