In terms of soil, it is also required to have good air permeability and drainage. Generally, it is a mixture of several media, such as small stone, bark, coconut shell, bark, slag, etc., or a mixture of humus and peat soil.
Orchids have better water storage capacity and less water consumption, so they are more drought resistant. But the water demand of orchids is relatively large when they grow. Watering needs to be adjusted according to the environment and growth conditions of orchids.
When the temperature is high, the evaporation is large. At this time, more water is needed. But if the temperature is low, less water is needed. Secondly, it's the light.

So you can direct sunlight before 7 o'clock in summer, and then you need to block it.
In the actual operation of orchid planting, according to the requirements of orchid for light, adjust the light.
