1、 Temperature

In general, the best growth temperature of orchid is between 20-35 degrees. Too high and too low temperature are unfavorable to plant growth. Orchids can grow rapidly when the temperature is above 20 degrees, and the most vigorous time of plant metabolism is between 28-32 degrees. Therefore, when maintaining orchids indoors, it is necessary to ensure that the growth temperature of orchids is between 20-35 degrees, and the temperature difference between day and night should be about 10 degrees

The minimum temperature for maintaining orchids should not be lower than 5 degrees, otherwise the plant will be frostbitten or even killed, and the maximum temperature should not be higher than 35 degrees, otherwise the plant will grow slowly. When the temperature is too high, it can be cooled by spraying water around the plant and increasing ventilation. When the temperature is too low, the plants need to be placed in a warm place indoors for maintenance

2、 Humidity

Orchids grow well when the relative humidity of the air is 40-70%. In such a humidity environment, the plants appear shiny and oily. Too dry or too wet will cause adverse reactions to the plants. A hygrometer is placed next to the orchid, which can directly monitor the humidity of its growing environment

When the hygrometer often shows less than 40% every morning, you can inject clean water into the water tray of the flower pot, and then remove the clean water when the hygrometer shows 75%. In the afternoon, if the hygrometer shows about 30%, there is no need to deal with it. It will rise again in the evening. When the humidity is too high, windows can be opened to increase ventilation, which can reduce the relative humidity
