How often do hydroponic plants change their water? How do I change the water?

The water change time of normal hydroponic plants is better than 5-7 days, which can be adjusted according to the changes of the season, just hydroponic plants, need to change the water once in 1-2 days, the temperature is higher in summer, the plants grow vigorously, the water quality is easy to become dirty, to shorten the water change interval, and most of the plants are in the dormant period in winter, and the water change interval can be extended. Be sure to change the water of your hydroponic plants regularly.

Water change tips. 1. When changing the water for hydroponic plants, the root system of the plant should be cleaned first, the mucus on it should be cleaned up, and some of the rotten roots or old roots that have lost their absorption capacity should be cut off, and the attachments on the inner wall of the container should be cleaned, and the water quality should be replaced with new water after treatment.

2. When hydroponic plants, it is wrong to completely soak the root system of the plant in water, and it can not be too full when adding water, and keep the root system of the plant 2 3 in water, so that the root system can ensure the absorption of water by the root system, and can also absorb oxygen from the air.

The most suitable frequency of water changes for hydroponic plants is 7 to 10 days. However, the water change depends on the seasonal situation, and the flowers that have just been hydroponics require 1 2 days to change the water once a day. In summer, plants grow vigorously, the temperature is high, the water is perishable, and the time should be shortened.

In winter, most plants are semi-dormant or dormant, with lower temperatures and longer intervals between water changes.

Hydroponic plant water exchange method:

1. Cleaning of roots and containers.

When changing the water, the root system should be cleaned, the mucus on the root system can be washed off with clean water, and some rotten roots and old roots that have lost their ability to absorb should be cut off. After the container is used for a period of time, some sediment will adhere to the wall of the vessel, and it is also easy to grow moss, so it should also be cleaned when changing the water.

2. The depth of hydroponics.

When hydroponizing flowers, the roots are often immersed in water, but this method is not appropriate, it is best not to add too much water, soak most of the roots in water, and leave one-third of the roots exposed in the air, so that the roots can absorb dissolved oxygen in the water, but also absorb oxygen from the air.

3. Water quality of hydroponics.

Generally, purified water is used as hydroponics easily. Purified water is desalinated water, with low salt content, and is suitable water for hydroponic flowers. In addition, qualified drinking tap water can also be used as water for hydroponic flowers, but tap water disinfection is commonly used liquid chlorine, excessive chlorine is harmful to the flower roots, and it should be placed for a period of time before use.

4. Change water and fertilize.

In terms of the amount of fertilizer and fertilization time, the main grasp of the principle of less fertilizer and frequent application, rather less than more, and according to the number of water changes, generally add a nutrient fertilizer every time the water is changed. to compensate for the loss of fertilizer caused by water changes. Hydroponic flowers should also be fertilized scientifically and reasonably according to their different conditions.

5. Prune in a timely manner.

For some hydroponic flowers that grow luxuriantly and have a more developed root system, when the branches of the plant are too long to affect the plant type, the excessively long branches should be pruned in time so as not to affect the ornamentation, and the branches cut by some plants can also be inserted into the equipment of the flower, so that it can take root and grow, so that the whole plant is more plump and perfect.

The best time to prune the roots is in the spring, and the best time to prune the roots is to start growing in the spring, and it can also be combined with water change to cut off the excess, aging, and rotten roots at any time to facilitate normal growth.

First, the initial stage of hydroponic plants, there are incisions on its plant body, if the water is not changed frequently, there are more bacteria in the water, which is easy to cause incision infection and affect the success rate of hydroponics, so it is best to change it once a day. After changing the water, you can put a small piece of charcoal in the water, the charcoal has the ability to adsorb, can suck away the bacteria and residue in the water, which will reduce the probability of the plant being infected by germs.

Second, in the middle stage of the mid-stage hydroponic plant, most of the incisions have grown roots, so the frequency of water change does not need to be too frequent, and it can be once every 2-3 days. The nutrients in the water are limited, and in order for the plant to grow well, liquid fertilizers must be added to the water to meet its survival needs and promote its growth.

3. During the dormant period, their ability to change water in all aspects will become very low, including the ability to absorb water, and the frequency of water change during the dormant period is once a week. Avoid water on the branches and leaves, as it has a reduced metabolic capacity when it is dormant, and the branches and leaves are prone to decay when exposed to water.

Fourth, the specific plant water changeSome plants do not need to change the water during hydroponics, only need to add water. For example, hydroponic sweet potatoes and potatoes have well-developed roots, and if they change water frequently, it is not good for root growth, so you can add water every time you add it until the initial water level. If there are small fish in the hydroponic plant, the frequency of water changes should reach the same level as everyday.

Hydroponic plants change the water every 5 7 days, just hydroponic plants every 1 2 days, and when the temperature is very high, change it every day. Every time you change the water, you should wash off the mucus on it with water, prune it, and then re-cultivate it after disinfection.

Hydroponic plants are generally changed every 5 7 days, mainly according to the change of seasons, if it is just hydroponics, it is best to change every 1 2 days, in the case of high temperature, you can change the water every day, when entering the winter, it should be changed every half a month.

Because the temperature is very high in summer, if you don't change the water often, it is easy to cause the root system to rot after breeding pathogens, so it is necessary to shorten the water change time, and most of the plants in winter are out of the dormant period, so the water change time can be appropriately extended at this time.

While changing the water of hydroponic plants, it is also necessary to prune properly, mainly to wash the root system first, wash the mucus on it, and then cut off the rotten roots and dead roots on it, and soak them in potassium permanganate solution for a few minutes to play a role in disinfection.

At the same time, the water can not be added too full, about half of the root system can be submerged, the water temperature should not be too high, mainly cold water, each time the water is changed, some nutrient solution can be added to it appropriately, so as to provide the nutrients needed for root growth, in order to facilitate growth and development.

1. The frequency of water change for hydroponic plants will be different in different periods.

2. In the early stage of hydroponics, there will be incisions on the plant body, so in order to avoid bacterial infection, the water should be changed every day. Medium-term water changes can be done without too frequent, once every 2-3 days. The plant's ability to absorb water is reduced during dormancy, so it can be changed once a week.

However, there are some special plants that do not need to be changed with water, as long as they are properly watered.

Hydroponics is also a way to raise flowers and plants, which is more convenient to take care of than soil culture. However, it is also necessary to pay attention to the methods of water cultivation and green plants, such as changing the water regularly, and leaving some old water and adding new water when changing the water. So how often does it take to change the water for hydroponic plants?

Generally, the interval of 3 or 4 days can be used, and the winter can be extended a little.

Hydroponic plants have high requirements for water quality during their growth. Clean and hygienic water must be ensured. Simply adding water does not guarantee the cleanliness of the water.

The water needs to be changed every 3 to 4 days to keep the water clean. Water change when you need to choose pure water or well water. When placing hydroponic plants in a vase for maintenance, the height of the water level should be controlled.

The rhizomes of the plant cannot be completely immersed in water, two-thirds or one-third of them must flow into the air, otherwise the plant will not be able to absorb oxygen normally, and eventually there will be hypoxic death.

It's best not to replace them all, but only a third or a half, so that the plants can adapt to the new water source more quickly and resume growth. If all are replaced, the acclimatization time will be longer, and some sensitive plants may be affected. In addition, pay attention to the frequency of water changes and water quality, not too often.

The water quality should be clean and clean, and it is best to use pure water for cultivation.

1. Generally, hydroponic plants should be changed with fresh water once a week, and newly cultivated plants should be changed with new water every 2-3 days.

2. Hydroponic plants will grow a lot of mucus after being in the water for a long time, which will attach to the root system. Gently rinse off the mucus from the top with clean water. Otherwise, there is too much mucus, which is easy to cause root rot and affect the growth of plants.

3. When changing the water, check the root system of the plant by the way to see if there are rotten roots or old roots, and prune them off. If the root rot is found to be serious, it can be soaked in potassium permanganate solution for sterilization. Inspect the branches and leaves again to see if there are any dead or yellow leaves. Trim them together.

4. Clean the breeding utensils every time you change the water, because moss and some impurities will be attached to the inside of the utensils, which not only affects the quality of the breeding water, but also affects the overall ornamental effect.

5. General hydroponic plants are shade-loving or semi-shade-loving plants. Many of them are cultivated indoors. There was no sunlight all day.

Over time, yellow leaves and wilting will appear. Hydroponic plants should also be suitable. Receiving astigmatism for photosynthesis.

Therefore, it is advisable to maintain an environment with good air circulation and proper astigmatism.
