Using dehumidifiers in greenhouse facilities is to scientifically and proactively address the problems caused by high humidity, such as diseases and growth inhibition. With its advantages of precision, efficiency, and energy conservation, it not only ensures the healthy growth and high-quality, high-yield of crops, but also plays a crucial role in achieving smart agriculture and sustainable farming. The high humidity in greenhouses mainly results from the enclosed environment and the transpiration of crops. When the relative humidity of the air remains above 80% for a long time, a series of problems will arise. Modern intelligent dehumidifiers can monitor the air conditions in real time and automatically switch based on preset values, ensuring that the humidity remains within the optimal range (such as 60%-70%), without the need for frequent manual intervention.

The problem of re-humidification of tobacco leaves has always been of great concern to tobacco farmers. This is mainly because if tobacco leaves do not absorb sufficient moisture, they will become dry and brittle, causing great difficulties in the transportation of the leaves. The tobacco industry knows that tobacco leaves are also classified by grades. To produce tobacco leaves of good quality, maintaining the relative humidity of the air is very important. One of the indicators for measuring the value of tobacco leaves is the completeness of the leaves. If the tobacco leaves are not complete, they will not fetch a good price. Compared with the natural re-humidification method, many tobacco farmers now directly equip with tobacco leaf re-humidification machines. This equipment can shorten the re-humidification time. Generally, natural re-humidification takes 6-7 hours, and this is still under humid weather conditions. Using the re-humidification machine, it only takes about 2 hours to re-humidify one bale of tobacco leaves, without being restricted by the weather environment. Sometimes, even after re-humidification, the tobacco leaves will become dry again after being placed for a period of time. With a re-humidification machine, it can be used at any time to ensure that the moisture content of the tobacco leaves does not decrease, thus avoiding the problem of brittle tobacco leaves. At the same time, the re-humidification machine also has the advantages of convenient operation, good atomization effect, and saving time and labor.

The spray humidifier used for edible fungi cultivation is designed to increase the air humidity, allowing the fungi to grow in a more suitable environment. Edible fungi prefer a humid environment for growth. If the air is too dry, the growth rate and yield of the fungi will be affected. Therefore, it is necessary to humidify the mushroom house at this time, so as to increase the air humidity and thereby promote the growth of edible fungi and increase the benefits of mushroom farmers. Many people think that edible fungi only need to increase humidity during the mushrooming stage, but they neglect the humidity management during the mycelium growth stage. This idea is not only widely present among ordinary cultivation households, but even some factory-based edible fungi enterprises also ignore the humidity management during the mycelium growth period, believing that no humidification is needed during the inoculation stage.
