What humidity level should be maintained in the cooler for flowers?

Maintaining a humidity level of 90-95% in the cooler for flowers is crucial for preserving their quality and extending their shelf life. High humidity helps to reduce water loss from the flowers, thereby maintaining their turgidity and overall appearance. Flowers naturally lose moisture through transpiration, and at higher humidity levels, this process is slowed down. This is particularly important for delicate flowers that can wilt or dry out quickly.

While other humidity ranges may seem sufficient, they do not provide the optimal environment for prolonging freshness. Lower humidity levels can lead to premature wilting, browning, and a reduction in vase life due to increased transpiration rates. Consequently, the 90-95% range promotes a more stable and conducive atmosphere for flower longevity, which is vital for both retailers and consumers in the floral industry.
