What kind of water does hydroponic plant use?

Do you know what kind of water is good for hydroponic plants? How to change water for hydroponic plants? Let's give a brief introduction.

What kind of water does hydroponic plant use?

It's better to have pure water, or tap water. As the dissolved oxygen in water decreases with the increase of salt concentration, pure water belongs to desalted water with low salt content, so it is suitable for hydroponic flowers. In addition to low salt content, pure water has the advantages of good transparency and no pollution, so it is the most ideal water for hydroponic flowers. In addition, qualified drinking tap water can also be used for hydroponic flower culture. After filtration, disinfection, impurity removal and other steps, tap water reduces the salt content to a certain extent, has fewer germs, and is convenient to take, so it is a more suitable water for hydroponic flowers. However, tap water disinfection commonly used liquid chlorine, excessive chlorine is harmful to flower roots, in order to release chlorine, need to be placed for a period of time before use. River water, lake water, pond water and well water are high in salt and can not be used for hydroponic flowers.

How to change water for hydroponic plants

Step one:

Water change time: generally, the water change time is 5m / m / m for 7 days. But the change of water depends on the season. Flowers that have just been hydroponically cultivated require a change of water once every two days. The summer plant growth is exuberant, the temperature is high, the water is easy to deteriorate, the time should be shortened. In winter, most of the plants are semi-dormant or dormant, the temperature is lower, and the interval between changing water can be longer. Generally speaking, the interval between changing water is shorter, which is beneficial to plant growth.

Step 2:

Cleaning of roots and containers: when changing water, the roots should be cleaned. Clean water can be used to wash away the mucus from the roots and cut off some rotten roots and old roots that have lost their absorptive capacity. After the container has been used for a period of time, the wall of the container will adhere to a precipitate, and it is also easy to grow moss, which should be cleaned when changing water.

Step 3:

Depth of water: when hydroponic flowers are cultivated, the roots are often immersed in water, but from the experience of cultivation, water should not be added too much, and a small amount of roots should be exposed in the air, so that the roots can absorb dissolved oxygen in water and oxygen from the air.

In addition: if there are conditions for flower friends, you can go to the flower market to buy a certain nutrient solution, which is more beneficial to the growth of hydroponic flowers!

Key points of changing water for hydroponic plants

1. Change the water every 10-15 days at about 20-25 ℃ (spring and autumn). Low temperature can appropriately prolong the time of changing water, while high temperature should be shortened.

2. When fish are raised together, the water should be changed frequently. It is best to buy a miniature air pump with a very low power consumption of about 3 watts. If properly inflated, the water change time can be greatly prolonged (generally, the water can be changed once in 1-2 months).

3. Tap water can be used, but it is best to leave it for one or two days. Mineral water or pure water can be used directly. The temperature difference between raw water and fresh water should not be too large. 6ML bagged nutrient solution is mixed into 2.25L large cola bottle and used. 300ml bottle nutrient solution each bottle cap solution mixed with 2.25L large cola bottle of clear water after use. The shelf life of diluted nutrient water is 6 months, which is usually stored away from the sun.

4. Due to the adsorption and metabolism of the root system and the activity of algae, the surface of the root system will be covered with foreign body after a period of time, which can be washed away carefully when changing water. If there is a dead root system, it should be removed when changing water.

5. The water in the bottle should not be too much, and it is appropriate to immerse it in water at about 2 × 3 of the root length.

6. The concentration of nutrient solution should be reduced when it is below 10 degrees in winter and higher than 35 degrees in midsummer (generally, the concentration of nutrient solution is 3-1 inch 2) or only with clear water.

This is the end of the introduction about what kind of water to use for hydroponic plants and how to exchange water for hydroponic plants. I hope the above content can be explained to everyone!
