How many days do hydroponic plants change water?

A lot of flower friends like to use water to grow plants at home, such as our common rich bamboo, anthurium, including the sweet potatoes we eat, pothos can be used for hydroponics, even if you cut off the side buds of a spider plant to hydroponics, it can also grow very well, in the process of hydroponic plants, its roots are in the water to absorb nutrients and water, water must be kept clean, so we must change the water regularly, when is it appropriate to change the water for him?

We must remember to raise hydroponic plants, to observe the water regularly, if the water is a little discolored, a little turbid, we can change the water for him in time, do not change it every few days, because the temperature of our environment is different, our water quality is different, including how much the nutrient solution we add to change the water is different, and the degree of its water is not the same, so it can not be calculated according to a few days. It is necessary to observe when the water quality is dirty, and replace the water in time, so as to ensure that its root system is clean, and after the root system is clean, it can absorb the nutrients and water in the water quickly, and the plant will not have problems.

In the family, hydroponic plants must remember that the light should not be too strong, because we plant it in hydroponic bottles, hydroponic bottles are generally transparent, if you put it in a place with strong light, its root system itself grows in dark soil, if the light is too strong in the water, it will cause sunburn to its roots, and even a layer of green attached to the root system will hinder him from absorbing nutrients, so try to put it in a place with low light, if you want to give it light, Whenever possible, choose an opaque hydroponic bottle so that he will grow even better.

Hydroponic plant nutrients are indispensable in the family, many flower friends will directly use compound fertilizer particles to put into the water, which is not right, even if you go to the water-soluble fast-acting fertilizer directly into the water, it is also difficult to absorb, because the root system is very weak, these fertilizers are relatively large, and the amount will cause the root system to burn after the dosage, and it is easy to rot the roots. For example, we ferment organic fertilizer at home, these can be added to him appropriately, when using each change of water to him a few drops, to ensure that there is a weak fertilizer in the water, its root system itself is aquatic roots, the absorption of nutrients is relatively slow, so that there will be no lack of nutrients, will not lead to it yellow leaves and so on.

This is what hydroponic plants must know, the first point is to see the light reasonably, the second point is to ensure that the water quality is clean, replace the water in time, and the second point is to give it regular supplemental nutrients, the environmental temperature of maintenance should not be too low, according to the different plants of each plant, try to put it in a place with a higher temperature, so that it can ensure that there are no problems, normal growth, normal flowering.

Hydroponic plant water change refers to the replacement of water with nutrient solution in the bottle, in general, 5 to 10 days in spring and autumn; Change the water about once every 5 days in summer; Change the water every 10 to 15 days in winter.

I always change the water every week or so, and even if the hydroponic plants are not changed, there is not much harm, as long as the plants are not short of water.

The water is changed every 3 days, once a week in winter, and every 2 days in summer. Whether or not to change the water is determined by the temperature and the season.

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.

It is better to change the water once every 5-7 days for hydroponic plants, first clean up the mucus on the root system of the plant when changing the water, cut off the old roots that are partially rotten or lose the ability to absorb, and then clean off the attachments on the inner wall of the container, and then add new water quality to the container, and add 3-5 drops of nutrient solution, and finally soak the 2 3 of the plant roots in water.

The water change time of 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 plant grows vigorously, the water quality is easy to become dirty, it is necessary to shorten the water change interval, and most plants are in the dormant period in winter, and the water change interval can be extended.

When changing the water of hydroponic plants, the roots of the plants should be cleaned first, the mucus on them 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 after treatment.

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 the root system of the plant 2 3 can be kept in water, so that the absorption of water by the root system can be guaranteed, and oxygen can also be absorbed from the air.

When hydroponic plants, it is best to use pure water, which belongs to desalinated water, with low salt content, which is conducive to the growth of plants, and 3-5 drops of nutrient solution should be added to the water during the water change to supplement the loss of nutrients in the process of water change.

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.

Generally, the water change time is 5-7 days. However, the water change depends on the season, and the flowers that have just been hydroponic require the water to be changed once every 1-2 days. 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. In general, the shorter intervals between water changes are beneficial to plant growth.

Changing the water of hydroponic flowers during irregular periods is also one of the key points in managing plants to keep the hydrotrophic solution fresh. Cultivation water can be used spring water, well water, etc., and tap water should be left for a day or two before use. The water change time can be determined according to the specific situation of the culture, and the water can be changed every 3-5 days in spring and summer; Change the water every two weeks in autumn and winter.

If the water is pure, clean, and the plants and roots are growing well, the water change time can be extended to replenish the amount of evaporated water.
