1, hydroponic plants can evaporate water freely, and play a more obvious role in regulating air temperature than potted plants in the same environment; It can also save the management of basin soil, which is clean and hygienic and simple to maintain. If equipped with a suitable container, you can watch the whole plant, and the ornamental value is higher.
2. There are two kinds of hydroponic plants: one is aquatic flowers, such as the familiar lotus and water lily; The other is flowers that can be raised in water. Usually, they grow in soil or culture medium, such as narcissus and hyacinthus orientalis. Because there is not enough light in the room, it is more suitable for cultivating the latter category. In addition, they have low requirements for nutrients and can basically grow in tap water without adding nutrient solution. Among the families, the suitable species are Chlorophyll, hyacinthus orientalis, Phyllostachys pubescens, Chlorophytum, Evergreen with leaves, Evergreen with heart leaves and Evergreen with Millennium.
3. The plants in the water generally include: lotus (lotus root), water lily, water chestnut, water shield, laver, Ceratophyllum, black algae, Zizania latifolia, arrowhead, water dropwort, water hyacinth, green algae, cyanobacteria and kelp.
4. Generally, these plants don't need special management, just have a container with a certain volume for the roots to extend, and the open glass container is more conducive to maintaining water quality and root growth. Avoid soaking leaves with water when planting, so as not to cause rot; Under suitable lighting conditions, it can take root quickly. When it is found that there is little water, add some water to prevent the root system from drying; When the water becomes dirty, take out the plants, clean the container and refill the water. Generally, hydroponic plants change water once every three days and apply nutrient solution once. The proportion and dosage of nutrient solution depend on the size of plants.
