Can succulents be placed in the bedroom?

Many people like to grow succulents and like to put them in the bedroom. So, can succulents be placed in the bedroom? In fact, they can, because the stomata of these plants open at night and can absorb carbon dioxide.

1. Most plants carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, and respire at night, absorbing oxygen and releasing carbon dioxide. Therefore, plants are generally not suitable for indoor planting and placement, as they will increase the carbon dioxide content at night. Nighttime is often the time when people rest in the room, which is not good for the human body.

2. However, many cacti and succulents are just the opposite. Because they grow in dry and hot areas, they close their stomata during the day to avoid water loss. At night, their stomata open to absorb CO2 and then form malic acid which is stored in large vacuoles. They release CO2 during the day for photosynthesis. This unique metabolic mode is called "Crassulacean acid metabolism".

3. Therefore, cacti and succulents are very suitable for indoor planting.
