HUMADITY.....Orchids

humidity
Orchids need humidity is relatively higher compared with other plant species.
Humidity is water vapor in the air. The temperature determines the amount of water vapor that can be stored in the air.
Moisture level is measured by relative humidity (relative humidity) in units of percent showing the number of water vapor in the air than the maximum water vapor that can be stored at a particular temperature.
Hot air hold more moisture than cold air, so if the temperature rises the percentage of water vapor in the air will fall. If the humidity exceeds 100%, then the water vapor condenses in the form of rain.
Tools to measure the relative humidity is called a hygrometer.
In general, orchids like humidity ranged between 40% s / d 80%.
Humidity is very important for several genera such as Cattleya, Phalaenopsis, etc..
Spray the plants in the morning, soaking the floor or using a humidifier (room humidifier) can help increase humidity.
Air must always move around plants to prevent spread of bacteria and fungi diseases, especially if there is high humidity and / or cold temperatures.
To reduce the air humidity can use the fan.
Orchid consists of various kinds (genus) and the above information is to orchids in general.
