1、 Water exchange method

During hydroponic maintenance, the water quality shall be clean and the water shall be changed in time. When changing water, try not to hurt its root system. Just pour out the water in the vase directly. If there are pebbles and other things in it, take them out carefully and put them back after cleaning. Pour it out and then add the prepared clean water. In addition, it should be noted that if the tap water is used, it should be dried for two days before use, and the chlorine contained in it should be released clean, so as to be conducive to plant growth

2、 How often

How often to change the water during hydroponic culture depends on the season. Usually, you don't need to change it too often. Just add water in time after the water volatilizes. In spring and autumn, the temperature is appropriate and the growth is fast. At this time, the water is changed about once a week. In summer, the weather is hot and the temperature is high. You should change the water frequently to avoid mosquitoes laying eggs in it. It is about once every two or three days. It grows slowly in winter and doesn't need to be changed often. It's usually changed once in half a month. In addition, if you want it to grow better and more vigorous, you should add an appropriate amount of nutrient solution every time you change the water
