Do hydroponic plants need to change the water? I didn t buy a nutrient solution, how can I take care

Don't know exactly what kind of hydroponic plant you're buying? It stands to reason that plants should be changed frequently, and I planted one that was smooth sailing. I haven't bought a nutrient solution, and I usually just change the water and spray some water on its leaves.

And through my own experience, I found that smooth sailing doesn't seem to like the sun very much, every time I move it out to bask in the sun, when I move it back, I will find that the leaves will turn yellow, so I keep it indoors, only every two or three days to change the water. It's growing very well now, but it hasn't bloomed, and I don't know if it's because the nutrition can't keep up, but the leaves are green and look healthy. <>

I've been raising it for more than a semester and found that it has gotten a little thicker, and other than that, it hasn't changed much. When I first bought this pot, it was actually cultivated with soil, but I prefer hydroponics, so I asked the store if I could raise it in water, and the store said: Yes, just take it back, take it out of the pot, and wash the soil with water.

He also warned me that the soil must be thoroughly washed clean, otherwise its roots will be easily corrupted, and I don't know what the reason is, and it stands to reason that water and soil should not be corrupted, but the shop must know better than me, and do what he says.

Before raising this plant, in fact, I also raised pothos for a period of time, when I bought it, I also cultivated it with soil, and when I returned to it, I washed the soil and put it in the water to raise, but after raising it for a while, slowly the leaves began to turn yellow, one by one, and finally all of them turned yellow and died. Now that I think about it, it's possible that I'm raising some of the wrong things, so it's best to ask the store if there's anything you need to pay attention to when buying plants.

In the past, the method of cultivating plants was basically soil culture, but now hydroponic plants are becoming more and more common, and many people are also biased towards hydroponic plants. Because hydroponic plants look cleaner and more beautiful.

According to my personal experience of hydroponic plants, hydroponic plants need to change water, because the roots of plants will also produce some metabolites when they are metabolized in water, so that the water becomes turbid, and the respiration of plant roots needs clean water.

Normally, before hydroponic a plant, I will figure out its properties, such as whether it likes sun or shade, what kind of growth temperature it needs, and how much light it needs to give every day, so that I can take better care of it in the future. Therefore, before you decide on hydroponic plants, it is important not only to understand the properties of the plants, but also to make sure that the roots of the plants are treated and cleaned.

Next, you can add the right amount of water to the hydroponic vessel and soak the roots of the plant in water. Then, every 3 to 5 days, pour out some of the water in the vessel and add some new water. Why do you have to pour out some of the water and add some new water in the first place, instead of replacing it all with new water?

Because the plant also has a process of adaptation to the water environment in which it grows, it may not be able to adapt to all the previous water if it is replaced with new water. In this way, the cycle operation is carried out for a period of time, about 15 days. Step by step, you can pour out all the water in the vessel and replace it with new water.

If you didn't buy the nutrient solution, I don't think it's okay. The plants I use hydroponic methods myself include pothos, spider plant, hyacinth, and rich bamboo, which I have never used any nutrient solution for my hydroponic plants, but I also keep it well. Because I personally think that the nutrient solution contains chemical components, I don't like the water to be so turbid, but I still like the water to be more refreshing.

However, during the hydroponic period, you should carefully observe the changes of the plant, and if there is an abnormal situation, you should find a way to solve it in time, rather than putting a plant in the water, and then just leaving it in one place and ignoring it. Since you have chosen to raise it, you should take care of it and care for it regularly. Normally, green plants need light for photosynthesis, which cannot be ignored, because with photosynthesis they can grow better.

If there is a long-term lack of light and photosynthesis is not possible, the plant will not grow well.

Finally, to sum up, hydroponic plants need to be changed in water. If you don't buy a nutrient solution, put the plant in a suitable growth environment, regularly observe the changes of the plant, and give it the right light. If there is an abnormal situation, find a way to solve it in time, so that the hydroponic plants will be well maintained.

Hydroponic plants generally use a nutrient solution rich in phosphorus, or a nutrient solution containing acidic substances such as nitrate nitrogen, the specific selection scheme is adjusted according to the habits of the plant, when preparing the hydroponic nutrient solution at home, you can put the rice water into the bottle to seal and ferment, and so on when the water quality turns yellow, it can be used, generally added when changing the water.

Hydroponic plants generally use a nutrient solution rich in phosphorus, or a nutrient solution containing acidic substances such as nitrate, and the specific selection scheme is adjusted according to the habits of the plant, and the nutrient solution that is not suitable for plant growth can not be applied, so as to avoid the occurrence of ***.

When preparing hydroponic nutrient solution at home, you can buy special high-efficiency fertilizer, pour it into clean water for stirring and dilution, and then put the nutrient solution into a watering can, or put the rice water into a bottle to seal and ferment, and wait for the water quality to turn yellow before use.

When hydroponic plants, when changing the water of the plants, add 2-3 drops of nutrient solution to the water to provide nutrients for the growth of the roots, and the concentration should not be too large, so as not to burn the roots, and open the window every morning to make the indoor air circulation and maintain the normal growth of the plant.

When using nutrient solution for hydroponic plants, it is best to use it in combination with other fertilizers to promote the balance of nutrients, and the nutrient solution should not be stored in metal containers, so as not to produce chemical reactions, which will affect the healthy development of plants, and should be used in glass, ceramics or enamel and other utensils.

You can choose to put a few fish in it, and the fish feces are the best nutrient solution for flowers. You can use the best hydroponic special nutrient solution on the market, and prepare the appropriate concentration according to the instructions, such as dilution 400 times or 1000 times, don't make a mistake about the proportion.

When preparing, the tap water should be left for two hours to half a day, and after its temperature is close to room temperature and the chlorine in the water has volatilized, the concentrated nutrient solution should be added in proportion, and it will become a nutrient solution that can raise hydroponic plants.

The suitable growth temperature of hydroponic plants is above 5 degrees above zero and below 30 degrees. In other words, as long as the temperature is comfortable for people, plants will also feel very comfortable, and they can grow normally, even in winter, they can flourish and add vitality to us.

There are three basic conditions that must be met by home stationary hydroponic flowers (or simply hydroponic flowers):

1. Select plants that are closely related to aquatic plants, that is, retain aquatic genes, and use them as stationary hydroponic flowers.

2. Choose a cultivation container that does not leak and has no bottom hole that matches the size and style of hydroponic flowers.

3. Adopt a low conductivity nutrient solution with ion balance absorption (appropriate ratio) and all-element mineral nutrients necessary for the growth of flowers and plants.

a) Macroelements: grams of calcium nitrate, grams of potassium nitrate, 8 grams of potassium dihydrogen phosphate, grams of magnesium sulfate.

2) Trace elements: disodium ethylenediaminetetraacetic acid mg, ferrous sulfate mg, manganese sulfate mg, boric acid mg, zinc sulfate mg, copper sulfate mg, sodium molybdate mg.

c) Purified water: 1 liter (1000 ml).

The pH value is to, and the conductivity EC millisiemens cm. The selected flowers are cultivated in a vessel and injected with hydroponic nutrient solution to become a static hydroponic flower with unique charm. It is best to use purified water to prepare the nutrient solution, of course, drinking tap water can also be used to prepare the nutrient solution.

They are all strictly treated, clean and hygienic, and meet the requirements of aseptic (less bacterial) cultivation. However, it must be fully noted that there are fewer impurities and germs in purified water, and it basically does not contain essential nutrients for plants, while tap water contains nutrients with unstable components as the composition of the water source changes. Therefore, the composition of the nutrient solution prepared with pure water is stable and consistent, and the composition of the nutrient solution prepared with tap water is unstable.

Liquid chlorine is used for tap water disinfection, and if there is too much chlorine in tap water, it is harmful to flowers and plants. A water purifier can be installed on the faucet. The tap water is released and stored in a larger-caliber bucket for a few days, stirred several times with a wooden stick to remove chlorine.

If you urgently need to change water, you can add 3 to 5 grains of sodium thiosulfate (commonly known as baking soda) to 10 kg of tap water, stir well, and also have the effect of removing chlorine.

Most foliage flowers prefer a slightly acidic soil environment, and their alkali intolerance is also immutable during hydroponics. Quiescent nutrient hydroponics must adjust the pH of the solution to 5The range of 5 can be conducive to the absorption of trace elements by flowers, physiological metabolism is not disturbed, normal growth, and green leaf color.

Nutrient solution can provide a lot of nutrients and can also kill bacteria, so it is best to use nutrient solution. It's very troublesome to match it yourself (I guess you're going to go to the fertilizer market).

Put cool boiled water, add vitamin B12, but to see a little sunshine, change the water once every three days, and when you change the water, be sure to rinse the roots with water.

Put a few fish in it, and the fish feces are the best nutrient solution for flowers.

1. Many hydroponic plants only need water to maintain the plants, and they can also grow normally and ensure a good ornamental effect. And some plants are easy to yellow and thin new leaves with water for a long time, at this time you need to add nutrient solution to improve the growth state, so how to choose the right nutrient solution, how to use the nutrient solution, the more filial piety is not the better, the following is a specific analysis of the use of the nutrient solution of hydroponic plants.

2. It is best to choose the products of regular manufacturers to choose hydroponic plant nutrient solution, there are often some "three no" products in the market, which are of poor quality and unreasonable formula, and some have a strong ammonia smell, which is not conducive to the absorption of nutrients by hydroponic plants. Some plants are very sensitive to changes in the concentration of nutrient solution, such as pothos, dripping Guanyin, etc., although it is very easy to hydroponics, but often change the nutrient solution of different concentrations, it is easy to have root rot. Therefore, when using the nutrient solution, try to change from light to thick, and do not change too much before and after use.

3. Don't be nervous when yellow leaves appear in hydroponic plants, and carefully analyze the reasons for yellow leaves, which can effectively prevent the occurrence of yellow leaves. Plants that have just started hydroponic will have some yellow leaves, which is a normal phenomenon, and the yellow leaves can be removed in time.

4. The inadaptability of hydroponic plants: everyone must think that plants that grow near the water are particularly easy to carry out hydroponics, and flower friends have found in practice that such plants can grow well in water for a period of time. However, after a month, they often fail to adapt to the environment in the vessel, and their growth deteriorates, and a large number of rotten roots appear.

For example, similar phenomena occur in purple stem taro, dripping Guanyin, mushrooms, etc. The original growth environment of this kind of plant is generally at the edge of flowing water, and they have strong adaptability when they are just hydroponics, but they can not get enough oxygen for a long time in hydroponics in small utensils, and because the original taproot is more adapted to the aquatic environment has changed, it is more difficult to grow aquatic roots that adapt to the hydroponic environment of the utensils, so they show their unadaptability.

5. When maintaining this kind of plant, a small part of the roots can be exposed to the water surface, especially pay attention not to add nutrient solution to the water, so as to maintain the good growth state of the plant, and at the same time ensure that there is more light time.

About 3 years. Hydroponic Fugui bamboo can live for a long time, and it is generally no problem to survive for 2-3 years. As long as it is given pure water during the maintenance period and the nutrient solution is properly added, it can grow well, but the plant is water senescent.

However, when it is senescent, it can be reused with stem cuttings.

Yes, hydroponic plants must be added with a nutrient solution.

Nutrient solution is the main mineral nutrient and water required by soilless crops, and its composition should contain complete components required by crops, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and other large and medium elements and trace elements such as iron, manganese, boron fertilizer, zinc, copper. The total concentration of the nutrient solution should not exceed 0 4%, and for the vast majority of plants, the concentration of nutrients they need should be around 0 2%.

If the nutrient solution is not added, the lack of nutrients in the water will lead to the lack of nutrients in the hydroponic plants and the symptoms of poor growth, weak yellow leaves, and slender branches. After adding the nutrient solution, the hydroponic root system will absorb the nutrients in the nutrient solution to provide growth, so that the hydroponic plants can grow and reproduce normally.
