What is the ideal temperature range for most greenhouse crops during the day?

The ideal temperature range for most greenhouse crops during the day is typically between 70°F and 85°F (21°C to 29°C). This temperature range promotes optimal growth and development for a wide variety of plants commonly cultivated in greenhouses. At these temperatures, plants are able to photosynthesize effectively, which is crucial for their energy production and overall health.

Temperatures that fall outside this range can lead to various issues for the plants. For example, if it's too cool, growth may slow down significantly, leading to a longer time to reach maturity. Conversely, if the temperatures rise above this range, it can result in heat stress, which may cause wilting, poor fruit set, or even plant death.

Maintaining this temperature range is essential for crop productivity, and greenhouse managers often employ various means such as heating systems, ventilation, and shading to ensure that the environment stays within this optimal range during peak sunlight hours. This understanding plays a critical role in greenhouse management and the successful cultivation of a diverse array of plants.
