Why do we need Flower & plant cold rooms?<\/h1>

Within the supply chain for flowers and plants, the use of dedicated cold storage<\/strong><\/a> is critically important. From the moment flowers are cut and prepared for shipment to florists until they reach the buyer, they must be kept in a cool, controlled environment above 0 \u00b0C with appropriate humidity. Otherwise, due to biological processes (such as the breakdown of sugars and starches in plant tissues to produce water, carbon dioxide, and energy), they wilt quickly and their vase life is shortened. That said, each type of plant must be stored under its own specific conditions.<\/p>

Types of Flower and Plant Cold Storage<\/h2>

An important point is that by using above-freezing cold rooms, we can prevent\u2014or at least delay\u2014wilting and microbial spoilage in plants. Today, various types of cold rooms are designed and built, which are generally classified into above-zero cold rooms<\/strong><\/a> and sub-zero cold rooms<\/strong><\/a>.<\/p>

Above-zero flower cold room<\/h3>

The appropriate temperature for flower cold storage is typically above 0 \u00b0C; therefore, above-freezing flower cold rooms are used for storing most flowers and plants. These facilities provide temperatures between 0 and 4 \u00b0C (near freezing). Of course, each type of flower and plant requires specific temperature and humidity conditions, but in general, this temperature range is suitable for most of them, as well as for many fruits, vegetables, and other plant materials.<\/p>

At the same time, humidity and ventilation (air circulation) in above-freezing cold rooms must be fully controlled. For example, the best relative humidity range for storing flowers is 90\u201395%. For some plants, such as herbaceous plants, an RH of 80\u201385% is appropriate. Certain flowers may also require particular humidity levels\u2014for instance, tulips should be held at a relative humidity of 70\u201375%, and some tropical flowers are best stored at around 10 \u00b0C with 60\u201385% RH.<\/p>

\"Cold<\/p>

One category of plants with significant commercial importance is cut flowers<\/strong>. Storage conditions for cut flowers differ somewhat from those of other flowers and plants; for example, the storage temperature for cut flowers is typically set between 0 and 2 \u00b0C. The cold room\u2019s relative humidity (RH) should also be maintained at approximately 90%.<\/p>

In constructing cold storage for cut flowers, it is essential to create conditions that prevent the production and release of ethylene gas, as the emission of this gas by flowers (due to unfavorable environmental conditions)can accelerate the degradation of floral and plant tissues.If proper conditions are provided,flowers can remain fresh for up to one month.<\/p><\/blockquote>\n
