How to take care of the dirty water of the green radish? How often should I change the water of the hydroponic green radish?

1. What to do if the water is dirty

When using water for cultivation, the water used must be clean. If you find that the water inside has become very dirty, you need to replace it in time. You can use tap water, but the water directly drawn cannot be used because it will be mixed with chlorine used for disinfection, which is not conducive to the development of the plants. It is necessary to take out the water some time in advance and leave it there. Firstly, it can volatilize the chlorine and precipitate other substances. Secondly, it can ensure that the water temperature is similar to the room temperature.

2. How often should you change the water?

In daily life, it is also necessary to change the water regularly. If the plants are allowed to be maintained in dirty water, their growth will be hindered to a certain extent. When you first start hydroponics, you can change the water more frequently, every 3-4 days. When it is growing vigorously, you can change the water every 10-15 days, and when it is growing slowly, you can change the water every month. If you don’t like changing the water frequently, you can also put an iron nail in the water, and then you can add some more water in it later.
