How to get water for hydroponics

Purified water is better than tap water

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

In addition, you can also use qualified drinking tap water for hydroponic plants, but liquid chlorine is often used to disinfect tap water. Excessive chlorine is harmful to the roots of flowers. In order to allow the chlorine to be released, it needs to be left for a while before use.

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

We often say that we should change the water once a week, but in fact, such frequent care of plants may not be good for them. Instead, it should be mastered flexibly according to the different conditions of the plants: some aquatic or wetland flowers are very adaptable to the hydroponic environment, and the time interval between water changes can be longer. Generally, it is okay to change it every 20 or 30 days.

However, some plants are not well adapted to the hydroponic environment after being hydroponically cultivated, and their recovery growth is slow, and some may even experience root rot after being hydroponically cultivated. In the early stages of the hydroponic environment, the water should be changed frequently, even once every 1-2 days. The frequency of water changes can be gradually reduced only after new roots sprout and normal growth resumes.

In addition to changing the water according to the plant's own conditions, you can also change the water according to the weather. In spring and autumn, change the water every 5-10 days; in summer, change the water every 5 days; in winter, change the water every 10-15 days.

More water is not better

This point is easily overlooked by everyone. When hydroponically cultivating, the roots cannot be completely immersed in water. Instead, a small amount of the roots should be exposed to the air, preferably more than one-third. In this way, the roots can absorb dissolved oxygen in the water and oxygen from the air.

The roots need to be cleaned in time

When changing the water, the roots should be cleaned. The mucus on the roots can be washed off with clean water. If rotten roots appear, they should be cut off in time. Generally, rotten roots will gradually rot from the root tip upwards. When pruning, cut to the normal root system. Old roots that have lost their ability to absorb water should also be cut off. After the container has been used for a period of time, sediment will adhere to the wall and it will also be prone to moss growth. It should also be cleaned when changing the water.
