What is the role of using an electric fan in orchid care?

Many orchid growers use an electric fan to blow air when growing orchids, which is a very normal management practice. With good ventilation, orchids are less prone to root rot and pests and diseases, so if the orchid-growing environment is not ventilated, after watering you should use an electric fan to blow the water on the orchid leaves dry, or when the weather is too stuffy and hot, use a gentle breeze to keep the air moving and maintain a cool environment. Only in this way can orchids grow healthily, improve their survival rate, and reduce the risk of death.
Especially in summer, when temperatures are high and humidity is great, in some large orchid gardens the orchid seedlings are all planted in pots and placed on rows of shelves, with relatively high density. Even if shade nets or bamboo blinds are installed, in hot weather the orchid garden becomes stuffy and unventilated, which is very unfavorable to orchid growth. The ventilation volume must be increased. Orchids' growth habit is to greatly favor good ventilation, so people install electric fans around the perimeter and at suitable positions in the middle of the orchid garden to increase the ventilation volume inside it.
In addition, installing fans has another very important function. Because many orchid gardens and orchid farms in the south are open-air, and because the weather in the south often rains, the moisture on orchid leaves and in leaf hearts and flower pots increases. To shorten the time water remains on the leaves, in the leaf hearts and in the flower pots, and to dry the water on the leaf hearts and leaves as quickly as possible, reducing the occurrence of diseases such as heart rot. Also, after spraying water on the leaf surface and watering the flower pots, the ventilation volume should be increased so that the leaf hearts and leaves are blown dry as quickly as possible, effectively avoiding heart rot and infection by other pathogens.
There are also some orchid growers who, when placing orchids on a home balcony, especially during the high-temperature period in summer, set up fans to blow air and cool things down. Because the suitable growth temperature for orchids is 18-28°C, when the temperature exceeds 30°C, growth will be hindered. Therefore, in order not to delay the normal growth of orchids, during the season suitable for orchid growth, fans are set up to strengthen ventilation, and at the same time some shading objects should also be set up. Especially after spraying water on orchid leaves, the ventilation volume should be increased even more, and if necessary a fan should be used to blow air to dry the water on the leaves and in the leaf hearts as quickly as possible, reducing the harm that water droplets bring to orchids. In summary, orchids should avoid being exposed to rain (heavy rain) as much as possible, and when the leaves are not particularly dirty, try not to spray water on the leaf surface. Sometimes after spraying water, the ventilation volume must be increased so that the leaf hearts and leaves dry as quickly as possible, avoiding losses.
