1、 Insufficient light

Some bedrooms are in the north or west direction. It is difficult for such bedrooms to raise flowers normally. Due to the lack of sunlight, it is difficult for flowers to absorb sunlight normally and synthesize nutrients. In the long run, there will be problems in the growth of flowers and poor growth. For some flowers that like sunshine, they must not be placed in the dark bedroom.

2、 Compete for oxygen

During the day, flowers will absorb CO2 through the contact of sunlight and then synthesize O2, but at night, the situation is the opposite. Because there is no sunlight, they will absorb O2 and compete with people for O2, resulting in limited breathing, which is also detrimental to people's health. Even the flowers placed indoors during the day should be moved out at night and should not be placed indoors as far as possible.

3、 Aroma stimulation

For flowers with stimulating flower fragrance, these must not be placed indoors, otherwise the strong aroma will stimulate people's nerves, make the nerves very excited, make it difficult to fall asleep and affect the quality of sleep.

4、 Distribute pollen

The space in my bedroom is very limited. Pollen will be distributed during flowering, which may lead to allergies.
