Purified water is better than tap water

Purified water belongs to desalted water with low salt content, which is suitable for hydroponic plants. In addition to low salt content, purified water has the advantages of good transparency and no pollution. It is the most ideal water for hydroponic plants

In addition, qualified drinking tap water can also be used as water for hydroponic plants, but liquid chlorine is often used for tap water disinfection. Excessive chlorine is harmful to flower roots. In order to release chlorine, it needs to be placed for a period of time before use

You don't have to change the water once a week

We often say that we change the water once a week. In fact, taking care of plants so frequently is not necessarily good for them. Instead, it should be flexibly mastered according to the different conditions of plants: some aquatic or wet flowers are very suitable for the hydroponic environment, and the water change interval can be longer. Generally, it's OK to change it every 20 days or 30 days

Some plants do not adapt to the hydroponic environment after hydroponics, and their recovery and growth are slow, and even root rot will occur after hydroponics. In the initial stage of hydroponic environment, the water should be changed frequently, even once a day or two. The number of water changes can not be gradually reduced until new roots sprout and resume normal growth

In addition to the conditions of the plants themselves, the water can be changed every 5-10 days in spring and autumn according to the weather; Change the water once every 5 days in summer; Change the water every 10-15 days in winter

The more water, the better

This is easy to ignore. In hydroponic culture, you can't immerse all the roots in water, but expose a small amount of roots in the air, preferably more than one-third, so that the roots can absorb dissolved oxygen in water and oxygen from the air

The root needs to be cleaned in time

When changing water, the root system should be cleaned and the mucus on the root system can be washed away with clean water. If rotten roots appear, they should be cut off in time. Generally, rotten roots decay gradually upward from the root tip. When pruning, they should be cut until the normal root system. The old roots that have lost their absorptive capacity should also be cut off. After the container is used for a period of time, a sediment will adhere to the wall, and moss is easy to grow. It should also be cleaned when changing water
