What Is the Floral Fridge Temperature?
A refrigerator or floral cooler's ideal temperature is between 34 and 36 degrees Fahrenheit for cut flowers in a hydrating solution. although it is common to find units that hover around 38 F plus or minus 5 degrees, it is not recommended as it can destroy or shorten the lives of flowers. If the flowers have been removed from the hydrating mixture and placed in a preservative emulsion, they store best at a constant 34 F.
To prevent drooping or lost blooms, fresh flowers are best kept between 34 and 36 degrees Fahrenheit. The containers should be plastic as metal may alter the pH balance of the water or alter the preservative qualities of additives.
The humidity of floral storage areas must be carefully controlled. Storage and display units need humidity levels of 90 to 95 percent. Flowers placed in preservatives require a minimum humidity level of 80 percent.
