1、 How many days do you change the water

At the beginning of hydroponic culture, the root system has not yet grown. At this time, in order to promote it to take root as soon as possible, the frequency of changing water should be higher. You can change water every 2-3 days to provide fresh nutrients for the plant and promote the root system to grow. After maintenance for about a week, it can take root. After the root growth is stable, the water change frequency can be reduced, and it can be changed once in about 10 days. In the subsequent maintenance, the change of water does not need to be too frequent. It is still to change the water for about 7-10 days, as long as the water quality is not turbid. The growth trend in winter is relatively slow. At this time, the water change frequency can be reduced, and the water can be changed once in 15-20 days. If the water change frequency is too high, it is unfavorable to the stability of the root and will affect the growth

2、 How to change water

1. Water quality: the replaced water quality can be well water, which is more suitable for hydroponic culture and can provide sufficient nutrients. If there are no conditions, you can also use the tap water after standing. Do not use it directly. First connect it and put it aside for a few days to ensure that the chlorine volatilizes and the water temperature can be equal to the room temperature, so as not to cause damage to the root

2. Change water: pour out the water in the bottle, clean it with clean water and disinfect it. The root of the plant should also be cleaned, pruned properly, and then put water in the bottle to insert the plant
