This plant cultivation technology, which embodies advanced productivity, has the advantages of intensive, large-scale and precise production. The hydroponic plants (Hydroponics flowers) cultivated using this soilless cultivation technology have been favored by domestic and foreign flower consumers for their cleanliness, elegance, strong ornamental value, and environmental protection and pollution-freeness.

But it is worth noting that the varieties and quality of hydroponic flowers produced in various countries around the world are not very ideal. The most fundamental reason for this is that hydroponic flowers are easily restricted by hypoxia and nutrient imbalance during their growth, which often leads to root rot, yellowing leaves and other poor growth phenomena in hydroponic flowers, and the water quality deteriorates, further affecting the growth of hydroponic flowers and their ornamental value. Therefore, in the process of hydroponic flower growth, solving the balanced supply of oxygen and nutrients in the nutrient solution is the most critical link.

The main ones are: Hulk, Guangdong Dieffenbachia series, Clustered Spring Feathers, Emerald, Green Ivy, Variegated Dieffenbachia, Golden Queen, Silver Queen, Star-pointed Dieffenbachia, Mini Monstera, Black Beauty, Green Yellow, Ruby, Fiddle-leaf Philodendron, Silver-wrapped Taro, Wrapped Taro, Calla Lily, Flamingo Anthurium, Calla Lily, etc.

This type of flowers is highly adaptable and has a natural instinct for hydroponics. Almost all flowers of the Commelina family can adapt to hydroponics conditions, such as: Purple-leaved Commelina, Purple-backed Dieffenbachia, etc.

Most of the lily family flowers can adapt to the conditions of hydroponics, such as: Haworthia, Chlorophytum, Cordyceps, Dracaena, Millennium Tree, Tiger Tail, Agave, Golden Edged Lucky Bamboo, Squill, Silver Edged Dieffenbachia, Lucky Grass, etc. However, the bottle orchid of the lily family is not easy to be hydroponically grown.

The ones that are more suitable for hydroponics are: lotus palm, hibiscus palm, silver wave brocade, gem flower, ground root, etc.

Coral, Cyperus, Coleus, Purple Velvet, Pine, Begonia, Paphiopedilum, Croton, Cineraria, Cactus, Schlumbergera, Triangular Column Grafted Ball, Dragon God Tree, Pineapple, Caiyun Pavilion, Leopard, June Blood, Ivy, Ivy, Kidney Fern, Bird's Nest Fern, Bamboo Palm, Miniature Coconut Tree, Spider Egg, etc.

1. Choose utensils. According to the species, shape, specification and color of the plant materials you want to hydroponically cultivate, choose substitute bottles, pots, jars and other utensils that can complement the species of flowers and trees. According to the principles of hydroponic utensils selection mentioned above, purchase or process them yourself so that they are used properly and look elegant. Do not use the utensils you use casually or indiscriminately, so as not to affect the image of hydroponic flowers and the beauty of interior decoration. Make sure that the utensils, flowers and living environment are unified and harmonious to achieve a more ideal viewing effect.

2. Remove the soil and wash the roots. The indoor flower hydroponic technology described here mainly refers to the technology of changing soil cultivation to hydroponic cultivation, so the work of removing the soil and washing the roots must be done well. As we all know, soil cultivation is organic nutrition, and after changing to hydroponic cultivation, it is completely changed to inorganic nutrition cultivation. The organic matter in the soil and attached to the roots must be strictly cleaned to avoid affecting the normal growth of hydroponic flowers and the infection of diseases and pests.

3 The method of washing roots is: dig the selected flower plants out of the soil or pour them out of the flower pots, first lift the branches and stems with your right hand, and gently support the roots with your left hand, then use your right hand to shake and pat them gently to make the soil fall off and expose the entire root system. Then soak them in clean water for 15-20 minutes, and then gently wash the roots with your hands. After 2-3 changes of water, wash until the roots are completely free of soil and the water for washing the roots is clear and transparent without mud and sand. But be very careful, some flowers have hard roots, twisted and intertwined, and a lot of soil is in the gaps. If necessary, use bamboo sticks or wooden sticks, or screwdrivers to dig them out. It is necessary to ensure that there is no soil left. This is one of the important links for the success of hydroponics, and you must not be careless.

A warm reminder from a hydroponic base technical expert: After washing the soil, you can appropriately cut off old roots, diseased roots, and old and yellow leaves according to the growth of the flower root system. Because the roots of hydroponic flowers are also an important part of appreciation, the beauty of their shape should also be considered when arranging the root system. After pruning the roots and leaves, wash them again in clean water to wash away the root hair residues left when pruning, so as to avoid contamination caused by bringing them into the hydroponic equipment. The daily maintenance of hydroponic flowers is quite simple, which is more worry-free and labor-saving than soil-grown flowers and plants. However, since many people are still new to this interesting way of planting hydroponic flowers, it is inevitable that they are a little unsure about the maintenance of hydroponic plants and feel that it is relatively mysterious. Let's talk about the maintenance and management methods of hydroponic plants.

Hydroponics is a developing industry in China. Bioengineering technology uses physical, chemical and bioengineering methods to domesticate common plants and flowers. It is loved by most people because it is easy to carry and care for, cheap, clean, and the leaves and flowers grow healthily, and it can achieve a picture of fish and flowers enjoying the same view. The market is very worrying! Because of the existence of fake hydroponics technology...

Hydroponic technology originated from some developed Western countries. When hydroponic technology was introduced, it changed fundamentally. For the sake of profit, some merchants directly put the cleaned plants into water without artificial training and bioengineering methods to save costs. In this way, the plants will not appear to die at the time, but after a few days, the leaves of the hydroponic plants begin to turn yellow gradually, and finally cause the hydroponic plants to slowly die. This is not only irresponsible to customers, but also harmful to the real hydroponic industry.

The real hydroponics is to place the plants in a nutrient solution, which is prepared by professional hydroponics technology. The plants are cultivated through artificial training or seedling cultivation, and the survival rate is as high as 95%. If combined with professional maintenance in the later stage, it can be said that they will not die. Therefore, only those who know the real hydroponics technology can cultivate hydroponics that will not die. Remind everyone to ask more questions when buying hydroponics, and don't buy fake hydroponics.

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

Mainly scattered light. What is scattered light? It is the natural light coming in from windows and other places, which is naturally scattered indoors. Generally, plants only need appropriate light to grow, and they don’t necessarily need to be exposed to the sun. In summer, they should also try to avoid direct sunlight.

Generally, you can use the hydroponic nutrient solution sold on the market. Follow the instructions to prepare the appropriate concentration, such as diluting 400 times or 1000 times. Don't make a mistake in the proportion. When preparing, leave the tap water for two hours to half a day, wait until its temperature is close to room temperature, and the chlorine in the water evaporates, then add the concentrated nutrient solution according to the proportion, and it will become a nutrient solution for growing hydroponic plants.

Changing water means replacing the water in the bottle with nutrient solution added. Generally, the water should be changed every 5-10 days in spring and autumn; every 5 days in summer; and every 10-15 days in winter (after leaving the tap water for half a day, add concentrated nutrient solution according to proportion).

Changing the water is to ensure the oxygen supply in the water. Fresh water contains more oxygen, and the plants will grow healthier. If the water is not changed for a long time, the plants can also survive for a period of time. For example, sometimes people are on business trips or vacations and are away from home for ten days, half a month or even a month. Soil-grown plants would have been unable to bear it and died long ago, but hydroponic plants can still survive as long as you add more water. However, if the time is too long, the water in the bottle is not fresh or has deteriorated, which will affect the growth of the hydroponic plants. In severe cases, it can also cause their death.

Note: When changing water, leave half or one-third of the plant's roots exposed.

Every time you change the water, rinse the roots of the plants and the container with clean water, and trim the dead branches, leaves, and rotten roots. Under normal growth conditions, hydroponic plants will periodically lose some of their roots and grow new roots. So when you find rotten roots, don't panic. Just use sterilized scissors (disinfected with alcohol cotton) to trim the rotten roots. Sometimes you can also trim some old roots to promote the growth of new roots (note: this should be done under the guidance of professionals). But be careful not to damage the aquatic roots, otherwise it will affect the growth of the plants.

The roots of hydroponic plants, those white and tender roots on them are aquatic roots. Some grow directly from the base of the stem, and some grow from the main root. They are all responsible for the absorption function of the plant, so be sure not to hurt them.

There is very little moisture in the air in winter, especially in the north. The indoor temperature is very dry, which is not conducive to the growth of plants. Therefore, please spray the leaves with clean water to maintain humidity. You can spray them with clean water twice a day.

When exposed to light, nutrient solution will breed green algae, which not only affects the beauty of the work but also hinders plant growth. Algae breeding occurs in containers made of hydroponic works or in aquatic induction seedling beds. How to effectively solve this problem is also an important technical issue in hydroponic production. For the breeding of bacteria and algae during the induction process, the electric field ultraviolet composite method can be used to solve it. The breeding in the container is more troublesome, and only maintenance control methods can be used, that is, changing the water frequently, and it is best to replace it with household drinking pure water or cold boiled water. This kind of algae and bacteria have a small base number, which is also conducive to control; you can also spray a layer of transparent photocatalyst on the inner wall of the glass container, which also has a certain algae removal and antibacterial effect. Its photocatalytic effect can decompose root secretions and play a certain role in preventing root rot. Acetic acid, ethanol, acetaldehyde, ethylene, etc. produced by root secretions can be catalyzed by photocatalysts to decompose into carbon dioxide and water. It can also be suppressed by placing a strong magnet or tourmaline at the bottom of the container. In addition, in addition to the above-mentioned electric field ultraviolet composite treatment, the ultraviolet ray-excited sterilization and algae removal technology of photocatalyst filter can also be used in production. This method has also been widely used in hydroponic production abroad and has achieved good results.

1. When the temperature is around 20-25℃ (in spring and autumn), change the water every 10-15 days. If the temperature is low, the water change time can be appropriately extended, and if the temperature is high, it should be shortened.

2. When raising flower fish together, it is advisable to change the water frequently. It is best to buy a micro air pump with very low power consumption of about 3 watts. Proper inflation can greatly extend the water change time (generally, the water can be changed once every 1-2 months).

3. Tap water can be used, but it is best to leave it for one to two days. Mineral water or purified water can also be used directly. The temperature difference between the original water and the new water should not be too large. 6ML bagged nutrient solution is added to the clean water in a 2.25L large Coke bottle before use. 300ML bottled nutrient solution is added to the clean water in a 2.25L large Coke bottle per bottle cap. The shelf life of the diluted nutrient water is 6 months. It should be stored away from sunlight.

4. Due to the adsorption, metabolism and algae activities of the roots, foreign matter will be covered on the surface of the roots after a period of time. You can carefully rinse and clean them with water when changing the water. If there are old and dead roots, they should be removed when changing the water.

5. There should not be too much water in the bottle. It is best to have about 2/3 of the root length immersed in water.

6. When the temperature is below 10 degrees in winter and above 35 degrees in midsummer, the concentration of nutrient solution should be reduced (generally 1/3-1/2 of the normal level) or only clean water should be used for cultivation.

1. Purified air is good for health

Scientific research shows that plants can absorb harmful gases and attach them to the surface of leaves, especially the roots of hydroponic plants.

They can add harmful gases and dust into their metabolic process and remove the toxicity during the material transformation.

Cultivated plants have a particularly good filtering effect on improving indoor air due to their plant properties and ability to bind with minerals. ^[1]

2. Beautify the environment

Place it on the floor in front of the window, and the effect is absolutely extraordinary. When you stand in front of a Monstera, you can feel that their elegant branches and leaves add a particularly beautiful atmosphere to the room, which is very pleasing to the eye, making you feel like you are on vacation at home. When your space is not big enough to accommodate tall plants, you can place small indoor plants on a bright windowsill to highlight and amplify their effect.

First of all, it should be noted that the roots of the plants cannot be completely immersed in water. The roots need to be exposed to the air for 5 to 10 cm. If the roots are completely immersed in water, the roots cannot absorb oxygen and will die due to lack of oxygen; the roots exposed to the air can supplement oxygen.

Secondly, change the water frequently to maintain the dissolved nutrients in the water.

Again, the composition of the nutrient solution for hydroponics should be appropriate and the concentration should not be too high!

As we all know, the medium of hydroponic flowers is water, and the fertilizer used is completely mineral inorganic nutrition, and it is made up of a variety of nutrients {macroelements and trace elements}. As for the nutrients contained in water, everyone is also relatively clear; the macroelements nitrogen, phosphorus, and potassium required by flowers are almost blank, and the trace elements contained are also very different from those in the soil. It is far from meeting the normal needs of flowers. Therefore, timely and reasonable fertilization of hydroponic flowers is undoubtedly a very important management measure. So how to master the characteristics, quantity, time and technology of fertilization for hydroponic flowers?

First, we should know that the flowers we plant are the use of bottomless pots, bottles, jars and other utensils, and the liquid fertilizer {nutrient solution} is applied in a hydroponic way. This is an obvious feature, so its fertilization technology is different from other cultivations. Because the substrate of soil cultivation is soil, and the surface of soil particles can absorb some nutrients, and the excess nutrients can also be automatically lost through the leak holes at the bottom of the pot, so it plays a certain buffering role in the concentration of fertilization. But the fertilization of hydroponic flowers is different. The various nutrient elements in the nutrient solution we apply are all dissolved in water. As long as it slightly exceeds the tolerance of flowers to fertilizer concentration, it will cause harm. Due to the above characteristics, strict control of the amount and type of fertilizer applied to hydroponic flowers is a very important part. Therefore, when applying nutrient solution, you should pay attention to using special fertilizers for hydroponic flowers as much as possible. And use it strictly in accordance with the instructions for use to prevent excessive application and excessive concentration from causing fertilizer damage.

Second, in terms of the amount and time of fertilization, the principle of applying less fertilizer frequently and less fertilizer rather than more fertilizer should be followed. According to the number of water changes, nutrient fertilizer should be added every time the water is changed to make up for the fertilizer loss caused by water changes.

Third, hydroponic flowers should be fertilized scientifically and reasonably according to their different situations.

Reasonable fertilization according to different flower types: This is because different flower types have different adaptability to fertilizers. The general rule is that flower types with slender root systems, such as coleus and begonia, are less tolerant to fertilizers and do not require a large amount of fertilizer and a large concentration. Therefore, when fertilizing them, the principles of light, less, and thin should be mastered. However, many flowers such as taro, ruby, and philodendron are more tolerant to fertilizers. The principle of less fertilization and frequent fertilization can be mastered. In addition, foliage flowers should be fertilized mainly with nitrogen fertilizers, supplemented with phosphorus and potassium fertilizers to ensure that the leaves are thick, the leaves are smooth, and the leaf color is pure. However, it must be noted that for flower types with colored stripes or patches on their leaves, less nitrogen fertilizer should be applied appropriately, because when too much nitrogen fertilizer is applied, the color of the leaves will fade or even disappear, and phosphorus and potassium fertilizers should be appropriately increased. For ornamental flowers, it is important to use phosphorus and potassium fertilizers mainly during the flower bud differentiation and development stage, supplemented with nitrogen fertilizers as appropriate, to avoid causing the plants to grow too tall, resulting in excessive vegetative growth that affects reproductive growth and causes adverse consequences such as small flowers, fewer flowers, lighter colors, or even no flowering.

Reasonable fertilization according to season and temperature: Generally, in summer when the temperature is high, the adaptability of flowers to fertilizer concentration decreases, so the concentration of fertilizer should be reduced at this time, especially for some flowers that are afraid of hot summer. In the high temperature season, they enter a dormant state, the physiological activities of flowers are slow, and the growth is also in a semi-stopped or stopped state. For such flowers, fertilization should be stopped at this time to avoid fertilizer damage.

Fertilize according to the growth potential of flowers: As we all know, the lighting conditions in our indoor environment are relatively poor. Although most of the foliage flowers raised indoors prefer shade or semi-shade environments, if there is a lack of light for a long period of time, or the light is too weak, the growth of the plants will be relatively weak, and thus the adaptability to the concentration of fertilizer will also be reduced. Therefore, for plants that grow poorly in an environment with poor lighting conditions or due to other reasons, fertilization should be stopped, or less fertilizer should be applied, and the concentration of fertilizer should be reduced as much as possible.

Several issues that should be paid attention to when applying fertilizer:

First, the flowers that have just been hydroponically cultivated have not yet adapted to the water environment, and their leaves often turn yellow or some of their roots rot. At this time, do not rush to fertilize them. You can wait for about ten days and then fertilize them after they have adapted to the environment or grown new aquatic roots.

Second, do not apply urea directly into the water, because urea is an artificial inorganic synthetic organic fertilizer. Hydroponics is cultivation under a sterile or low-bacteria state. If urea is applied directly, not only will the flowers be unable to absorb nutrients, but some harmful bacteria or microorganisms will also multiply quickly and cause water pollution, and produce ammonia to the flowers and cause flower poisoning.

Third, if you find that the fertilizer is too concentrated, causing the roots of the flowers to rot and the water quality to deteriorate and become polluted and stink, you should quickly cut off the rotten roots, and change the water and wash the roots in time.

Changing water and washing roots is an important part of ensuring the good growth of hydroponic flowers. So why do we need to change water and wash roots for hydroponic flowers?

First, the conditions for plant growth are mainly water, nutrients and air. The water and nutrients of hydroponic flowers can definitely guarantee their needs, while the oxygen content in the water will gradually decrease with the growth of flowers. When it decreases to a certain level, it will affect the growth of flowers due to lack of oxygen. Although the oxygen in the air will continue to be replenished into the water, the amount replenished is far from enough.

Second, the roots of hydroponic flowers growing in water absorb nutrients from the water on the one hand, and on the other hand, discharge some organic matter, waste or toxins into the water and deposit them in the water. When cultivated in soil, these organic substances mainly dissolve nutrients that are not easily absorbed by the roots, while waste and toxins are distributed in the soil space or flow out from the holes at the bottom of the pot, and will not be absorbed by the roots and affect the normal growth of flowers. However, there are no bottom holes in the hydroponic container, so these organic matter, waste or toxins are all deposited in the water and can easily be absorbed by the plant again. This vicious cycle of repeated absorption, excretion, reabsorption, and excretion is very detrimental to the normal growth of flowers and the normal physiological functions of flowers.

Third, the nutrients and fertilizers often applied to the water for hydroponic flowers, except for a part of the mineral elements being absorbed by the roots, the rest remain in the water. When the residual substances reach a certain amount, they will also cause certain harm to the flowers.

Fourth, the roots of hydroponic flowers growing in water for a long time will produce a kind of mucus. When there is too much mucus, it will not only affect the absorption of nutrients by the roots of flowers, but also pollute the water. Due to the above reasons, hydroponic flowers must be managed by regular water changes and root washing.

So, how do we master the technique and time of changing water and washing roots?

First, change the water regularly according to different types of flowers and their adaptability to hydroponic conditions. Some flowers, especially aquatic or wet flowers, are very adaptable to the hydroponic environment. After hydroponics, they can quickly grow new roots on the original root system and grow well. For these flowers, the time interval between water changes can be longer. However, some flowers are not very adaptable to the hydroponic environment after hydroponics, and their recovery growth is slow, and even root rot may occur after hydroponics. For these flowers, the water should be changed frequently in the early stage of entering the hydroponic environment, even once every 1-2 days. The number of water changes can be gradually reduced until new roots sprout and normal growth resumes.

Secondly, the temperature is closely related to the growth of plants. The higher the temperature, the less oxygen is contained in the water; the lower the temperature, the higher the oxygen is contained in the water. On the other hand, the higher the temperature, the stronger the respiration of the plants, and the more oxygen is consumed; the lower the temperature, the weaker the respiration of the plants, and the less oxygen is consumed. Therefore, the oxygen content decreases when the temperature is high, and the oxygen content in the water is high when the temperature is low. Therefore, water should be changed frequently in the high temperature season, and the time interval for water change should be longer in the low temperature season.

Third, if the flowers are growing normally and the plants are strong, the water change time is longer. If the flowers and plants grow poorly due to various reasons, the water change is more frequent. According to the above aspects, the requirements for changing water and washing roots can be roughly mastered as follows: in hot summer, change the water every 4-5 days, and in spring and autumn, change the water once a week. In winter, the water change time should be longer, generally changing the water every 15-20 days. When changing the water, be very careful to wash off the mucus on the roots, and remember not to break or injure the root system. If you find moss on utensils, rocks, etc., you should remove it in time. To improve the ornamental value and facilitate the normal growth of flowers.

Most hydroponic flowers, especially indoor hydroponic foliage plants, prefer higher air humidity. If the indoor air is too dry, the tips or edges of the leaves will burn, thus affecting the ornamental value of the flowers. Therefore, you should spray water on the plants frequently to increase the air humidity, which is conducive to the normal growth of flowers.

As we have said before, the quality of hydroponic flowers is directly related to the oxygen content in the water, and the amount of oxygen in the water is related to the activities of people indoors and the quality of ventilation. When indoor ventilation is poor and people are active, the oxygen content in the water decreases rapidly, which will affect the growth of hydroponic flowers. Maintaining good indoor ventilation can increase the oxygen content in the water. Therefore, for places where hydroponic flowers are grown, ventilation should be strengthened to maintain fresh air indoors and good growth of flowers.

For some hydroponic flowers with lush growth and well-developed root systems, when the branches of the plants grow too long and affect the plant shape, the overlong branches should be pruned in time to avoid affecting the viewing. The cut branches of some plants can also be inserted into the flower utensils to let them take root and grow, making the whole plant fuller and more perfect. The best time to prune the roots is in spring when the flowers begin to grow. It can also be combined with water changes to cut off excess, aging, and rotten roots at any time to facilitate normal growth.

We know that hydroponic flowers are inorganic nutrients, and organic matter should not enter the water, let alone organic fertilizers. Therefore, keeping hydroponic flowers clean and hygienic is a key measure to ensure their good growth. So do not put food and organic fertilizers into hydroponic flowers at ordinary times. Do not put your hands into the water at will to ensure that the water used does not deteriorate or pollute, keep it clean and hygienic, and ensure the growth of flowers.

Keeping hydroponic flowers warm in winter is a relatively difficult task. Generally speaking, if the indoor temperature is kept above 5 degrees, most hydroponic flowers will not be harmed. For greenhouses where the minimum temperature does not reach 5 degrees, necessary warming measures must be taken. ^[2]
