Plants have unique biological characteristics. When it is cool at night, the stomata open, exhale oxygen, absorb carbon dioxide and store it in the body for photosynthesis the next day. The stomata are closed during the day, and the fixed carbon dioxide is used for photosynthesis at night, which not only reduces water loss, but also carries out photosynthesis. This special metabolic pathway is to meet the needs of preserving life in arid environment, and also has the function of purifying air.
You can put some feng shui balls, colored small stones and so on on feng shui.
