The frequency of water change for hydroponic plants has always been a concern. The frequency of water change varies for different plants and in different seasons.

In spring and autumn, the climate is pleasant and the growth rate of hydroponic plants is relatively stable. Generally, it is recommended to change the water every 20 to 30 days. This is because the water temperature is moderate in spring and autumn, and the dissolved oxygen content in the water is also relatively stable. The metabolic activities of plants are relatively slow during this period, so there is no need for frequent water changes.

In summer, it is hot and the dissolved oxygen content in the water decreases rapidly. At the same time, the growth rate of plants accelerates and the oxygen consumption also increases. Therefore, it is recommended to change the water once a week in summer. This can ensure that there is enough oxygen in the water to meet the needs of plant growth.

In winter, the temperature is low and the growth of plants is slow. At this time, it is more appropriate to change the water every 10 to 15 days. Due to the low water temperature, the metabolic activities of plants also slow down correspondingly, and too high a frequency of water change will have a certain impact on plants.

In addition to seasonal factors, plant species can also affect the frequency of water change. For example, some aquatic plants such as Epipremnum aureum and Chlorophytum comosum have relatively developed root systems and a greater demand for water. These plants need regular water changes to ensure the cleanliness of the water quality.

When changing the water, the following points also need to be noted: First, clean the roots and utensils to remove the dirt and impurities on the surface; second, observe the growth of plants and adjust the frequency of water change in time if there is any abnormality; third, choose the appropriate water. Generally speaking, tap water can be used after precipitation.

The frequency of water change for hydroponic plants needs to be determined according to the season and plant species. A reasonable frequency of water change can ensure the healthy growth of plants and make our hydroponic plants more beautiful.
