What is the primary purpose of controlling humidity in a flower cooler?

The primary purpose of controlling humidity in a flower cooler is to limit water loss through transpiration. When flowers are stored in a cooler with optimal humidity levels, they are less likely to lose moisture, which is crucial for maintaining their freshness and extending their shelf life. High humidity helps to create a more suitable environment that minimizes stress on the flowers, allowing them to retain the moisture necessary for longevity.

In contrast, enhancing flower color tends to be influenced more by factors such as light exposure and proper nutrition rather than humidity alone. While humidity can indirectly affect pest infestations, controlling it is not primarily aimed at pest management; other practices are more effective for that purpose. Additionally, increasing the growth rate of flowers is typically a concern in cultivation environments rather than in storage, where the goal is to preserve the flowers rather than promote their growth. Therefore, maintaining adequate humidity is essential for preventing water loss, which directly impacts the overall quality and lifespan of the flowers.
