Temperature and humidity for growing orchids indoors

Article Catalog

---

When maintaining orchids indoors, you need to ensure that the growth temperature of the orchids is between 20 and 35 degrees, and the temperature difference between day and night should be about 10 degrees. The lowest temperature cannot be lower than 5 degrees, otherwise the plants will suffer frostbite or even die. The highest temperature cannot be higher than 35 degrees, otherwise the plants will grow slowly. Keeping the relative humidity of the air between 40-70% is beneficial to plant growth. You can place a hygrometer next to the orchid to visually monitor the humidity of its growing environment.

1. Temperature

Generally, the optimal growth temperature for orchids is between 20 and 35 degrees. Both high and low temperatures are detrimental to plant growth. Orchids can grow rapidly when the temperature is above 20 degrees, and the plant metabolism is at its strongest when the temperature is between 28 and 32 degrees. Therefore, when maintaining orchids indoors, you need to ensure that the growth temperature of orchids is between 20 and 35 degrees, and the temperature difference between day and night should be about 10 degrees.

The temperature for maintaining orchids should not be lower than 5 degrees, otherwise It will cause frostbite or even death of the plants. The maximum temperature cannot be higher than 35 degrees, otherwise the plant growth will be slowed down. When the temperature is too high, you can spray water around the plants and increase ventilation to cool them down. When the temperature is too low, the plants need to be maintained in a warm place indoors.

2. Humidity

Orchid in It grows well when the relative air humidity is 40-70%. In such a humidity environment, the plants will appear shiny and shiny. Too dry or too wet will cause adverse reactions in the plants. Placing a hygrometer next to the orchid can visually monitor the humidity of its growing environment.

When the hygrometer often shows less than 40% every morning, you can pour water into the water tray of the flower pot, and remove the water when the hygrometer shows 75%. In the afternoon, if the hygrometer shows about 30%, no treatment is needed. It will rise again in the evening. When the humidity is too high, you can open windows to increase ventilation, which can relatively reduce the humidity.
