Blood heart orchid water plants need carbon dioxide. Carbon dioxide is the raw material for photosynthesis of aquatic plants. When aquatic plants photosynthesize, they need to absorb carbon dioxide. Therefore, if there is no carbon dioxide in the water, aquatic plants can not carry out photosynthesis. It will lead to slow growth of aquatic plants, dwarf plants, leaf shedding and even death. When cultivating aquatic plants, carbon dioxide needs to be input into the water at regular time and quantity to ensure that the carbon dioxide in the water is maintained at a certain concentration.
Blood heart orchid water plants need sunshine. Sunshine is the condition for photosynthesis of aquatic plants. The photosynthesis of aquatic plants can only be carried out under the condition of sunshine. If there is no light condition, the leaves of aquatic plants will be dull, the aquatic plants will fade, stop growing, and may even rot and die. Therefore, in the cultivation of aquatic plants, it is necessary to provide certain light conditions. Blood heart orchid aquatic plants live in tropical areas of South America, which require more stringent illumination, and need to maintain illumination above 2500 Lux when breeding.
