Some bedrooms are located in the north or west direction. It is difficult for such bedrooms to raise flowers normally. The sunlight that comes in is insufficient. The flowers can not absorb sunlight normally and can not synthesize nutrients. In the long run, the growth of flowers will have problems, resulting in poor growth. For some flowers like sunshine, they must not be placed in the dark bedroom.
In the daytime, flowers will absorb CO2 through the contact of sunlight, and then synthesize O2. But in the evening, the situation is the opposite. Because there is no sunlight, they will absorb O2. They start to compete for O2 with people, resulting in limited breathing, which is also harmful to people's health. Even if the flowers are put indoors in the daytime, they should be moved out in the evening. Try not to put them indoors
