Winter "Air" Dry
The indoor air dryness can reach below 30% after heating in the north during winter, and the阴冷 environment in the south also affects the oxygen content in the living room. Choosing hydroponic plants can not only avoid the trouble of frequent watering but also naturally adjust the humidity through transpiration. The following four easy-to-care-for green plants are especially suitable for creating a healthy home environment.
Key Points for the Care of Coin Grass in Water Culture
Humidity Regulation Characteristics
The leaf transpiration area of coin grass reaches 15-20cm²/plant, and a single pot can release 50ml of water vapor per day. The surface of the round leaves is densely covered with stomata, which operate most efficiently in an environment of 18-25℃.
Light Management Skills
Place it on the east-facing windowsill to ensure 3 hours of scattered light per day. Direct strong light for more than 2 hours can cause the leaf edges to burn, while insufficient light can lead to the phenomenon of stem elongation.
Advantages of Green萝 Air Purification
Formaldehyde Absorption Capacity
NASA clean air research shows that 1 square meter of green萝 leaves can decompose 0.15mg of formaldehyde in 24 hours. It is recommended to place 2-3 pots in every 10㎡ of space, and using it with activated carbon can achieve a better effect.
Hydroponic Root Care
Use ceramsite to secure the roots, with the water level submerging 2/3 of the roots. Add 3 drops of nitrogen-containing nutrient solution every 7 days when changing the water, which can promote the development of aerial roots.
Rich Bamboo Oxygen Increase Solution
Nocturnal Oxygen Release Characteristics
The Crassulacean Acid Metabolism method allows it to continuously release oxygen at night, and placing 2-3 branches in the bedroom can increase the indoor oxygen content by 5%, effectively improving sleep quality.
Nutrient Solution Mixing Suggestions
Use a hydroponic-specific liquid with an N-P-K ratio of 3-1-2, add once a month, and keep the concentration at 800-1000μS/cm. Glass containers need to be cleaned regularly to prevent the growth of algae.
Spider Plant Air Filtration System
PM2.5 Adsorption Test
Laboratory tests have shown that a spider plant with a crown width of 30cm can intercept particles as small as 0.3 micrometers at a rate of 27%, and it is recommended to use it in combination with a humidifier to enhance dust removal effects.
Division Propagation Method
When the creeping stem reaches 8cm, keep 3 aerial roots for division. Use tap water that has been exposed to air for 2 days, and use vermiculite as a transition to increase the survival rate.
By scientifically caring for these four types of hydroponic plants, the indoor relative humidity can be maintained at an ideal range of 50%-60%, and the carbon dioxide concentration can be reduced by more than 20%. It is recommended to rotate the containers regularly to ensure even light exposure, combined with a thermometer and hygrometer for monitoring, allowing green plants to truly become natural environmental regulators.
