1. Is light indispensable

Although generally speaking, orchids are more shade loving plant species. However, you can't be in a completely dark environment. The role of light is also indispensable, which is mainly reflected in these aspects:

(1) Light is one of the important sources for plants to make nutrients. Without sunlight, the accumulation of organic matter will be hindered

(2) Light is also a necessary factor in its production of chlorophyll

(3) A series of important life activities such as the opening and closing of stomata, the absorption of water and the formation of flower buds all need the help of light

2. Treatment in different seasons

Mainly about winter and summer. The temperature in winter is very low, so we should accept as much light as possible so that it can survive the winter safely. However, the light is too strong in summer, but there must be no light. Therefore, they usually choose to receive the light before 7 o'clock in the morning. At this time, the light will be very soft and will not burn the leaves. After seven o'clock, about 50 to 90 percent shading is OK. In spring and autumn, scattered light is OK

3. Requirements of different varieties

The requirements for light are not only related to the season, but also related to the variety. For example, Jianlan has a relatively large demand for light. It can block 60 to 70% of the light. Cymbidium and Cymbidium are about 70 to 80 percent shading. Melanie doesn't like light very much. The shading is about 85%
