Hydroponics is to grow plants in water. The difference between growing plants in water and soil is the substrates. In fact, plants can grow well no matter what kind of culture substrate they are in, as long as they can provide the necessary conditions for plant growth, including sunlight, temperature, water, air and various elements. Even if you plant it in the palm of your hand, the flower will bloom in your hand with these conditions.The advantages of hydroponic plants: they are attractive, clean, have few limitations in container selection, and do not use traditional fertilizers.Hydroponic plants are easy to care for, which can also act as a natural humidifier in your home during the dry winter months. Don't worry about your hydroponic plants. Pinch a branch, wash the roots, change the water... It's easy to take care of. Which plants should we choose for hydroponics? How do you care for hydroponic plants? Here are 20+ best plants that grow in water to try at home.

Do Plants Grow Better In Water Or SoilNot all plants are suitable for growing in water. Hydrophonic plants have the following advantages:
There are two main groups of plants that can grow in water. One group is aquatic plants. They grow in the water in nature, such as lotus, water lily; Another kind is the plant that can hydropics, below normal circumstances they grow in soil or culture matrix, such as rich bamboo, hyacinth. They have low nutrient requirements and can almost grow in tap water, and some require only a small amount of nutrient solution.
- Because water can evaporate freely, in the same environment, hydrophytic plants can adjust the air humidity obviously.
- Hydrophytic plants can omit the care of basin soil, which is clean and hygienic;
- If you choose some plants whose roots can be exposed to light, with appropriate containers, the whole plant can be fresh and elegant, with higher ornamental value.
How To Grow Plants In WaterThe hydroponic method that elaborates here, basically is to switch soil culture to hydroponic culture. So cleaning roots is very important firstly. As we all know, soil cultivation is organic nutrition, and after changing to hydroponic culture, it is completely changed to inorganic nutrition cultivation, so the soil and organic matter attached to the root should be strictly cleaned before growing in water so as not to affect the normal growth of hydroponic plants and avoid the infection of diseases and insect pests.Dig out the plants to grow in water from the soil and slightly shake the root, making the soil fall off. Then soak the plant in clean water for 15 ~ 20 minutes, gently wash the root with hand, after 2 ~ 3 times of water cleaning, until the root is completely clean without soil. After washing the soil, according to the growth of plants root system, cut off the old roots, sick roots and yellow leaves, and dry the plants properly. Because the root of plants that grow in water is also an important part of ornamental, so when sorting out the root system, we should also consider the beauty of its form. After pruning its roots and leaves, we should clean them again in clean water to wash the root hair residue left when cutting. The daily care of water plants is quite simple, we will talk about how to care for water plants in the next section.
How To Care For Water Plants
Best Water For PlantsThe most important part of a hydroponic plant is water. What kind of water is best for plants that grow in water? The advantages and disadvantages of several types of water are discussed in detail below.
The author thinks mineral water is best for hydroponic plants. First of all, it is relatively clean and has no impurities other than trace elements and is very transparent. All in all, it's beautiful for hydroponics. Secondly, it is rich in trace elements and low in salt with rich nutrients, will not harm the roots.
A small magnet is added to clean water, and after a period of time the water will become magnetized. Magnetized water contains fewer minerals and is clean enough. It can promote plant metabolism, cell growth, enhance stress resistance, and make water plant leaves healthy, green and shiny. It also slows the growth of algae in the water, which has a good effect on the roots of water plants.The downside is that magnets are not everywhere and magnetized water is not readily available.
The high oxygen and nitrogen content of rainwater can make hydroponic plants' leaves greener and roots stronger, making it good water.But it cannot be obtained at any time and must be accumulated in advance in rainy days, somewhat dependent on the weather. At the same time, if the local air pollution is serious, the rainwater will shout a lot of pollutants, at this time, it is not suitable to use rainwater to hydroponic plants.
River/lake water has similar advantages to rainwater, with fewer minerals, less hardness, and some local micronutrients, which are also good for plants that grow in water.The disadvantage is that the water impurities, which is easy to breed small organisms, green algae and so on. You need to change the water more frequently. The water quality may be polluted by a variety of other chemical substances, sometimes can not be used safely.
This is more complicated, self-made nutritional water can be rice washing water, beer water, tea, milk water, vitamin water, etc., more suitable for hydroponic with other water. This water is rich in nutrients, which can promote the growth of aquatic plants, making them strong and beautiful in a short time.The disadvantages are that it cannot be used for long periods of time, and concentration is not easy to master. If you burn the roots by high concentration of nutrient water, it's not good for the plant. In addition, the homemade nutrient water has been fermenting for a long time, and the water will stink, which will greatly reduce the beauty of water plants.
Some people worry that boiled water will make nutrients disappear, indeed, after heating the nutrients in the water will be damaged to varying degrees. It is best to use with nutrient solution. However, after boiling cold water, impurities and calcium content will become less, bacteria can also effectively reduce, maintain a high degree of cleanliness. Growing plants in cold boiled water will keep the roots clean and beautiful for a long time, which is better than running water.These are some of the pros and cons of different types of water for hydroponics. If you're going to grow plants in water, you can contrast that with the present. Whatever water you use, change it regularly and remember to clean the roots and keep the roots and container clean.
How Often To Water Hydroponic PlantsChanging water and watering is an important step to ensure the good growth of hydroponic plants. So how often to change the water? How often to water hydroponic plants? How much water is for hydroponic plants?
Most of the hydroponic plants, especially indoor foliage plants that grow in water, like higher air humidity. If the indoor air is too dry, it will cause leaf curling. Thus affecting the ornamental value of water plants. Accordingly, we should often spray water to plant at ordinary times, raise the humidity of the air thereby, which is helpful for water plants growth.As we talked about above, the growth of hydropic palnts is directly related to the oxygen content in the water, and the amount of oxygen content in the water is related to the activities of indoor ventilation. When indoor ventilation is poor, the oxygen content in the water decreases rapidly, which will affect the growth of hydroponic plants, and maintaining good indoor ventilation can increase the oxygen content in the water. Accordingly, strengthen ventilation when growing plants in water.
- According to different plant species and their adaptation to hydroponic conditions, the water should be changed regularly. Some plants, especially aquatic plants, are well adapted to the environment of hydroponic culture. For these plants, change water at longer intervals. However, some plants do not adapt to the hydroponics environment very well after hydroponics, and their recovery and growth are slow, and even root rot will occur after hydroponics. For these plants, in the early stage of the hydroponic environment, should often change water, or even 1 ~ 2 days to change water. Gradually reduce the frequency of changing water until the new roots germinate and return to normal growth.
- Change water every about 10 ~ 15 days at 20 ~ 25℃ (spring and autumn). Appropriately extend water change time when the temperature is lower, and shorten when the temperature is higher.
- When growing plants in water with fishes, change water should be frequent. It is best to buy a miniature air pump, appropriate inflation, which can greatly prolong the time for changing water (generally 1 ~ 2 months for changing water).
- The temperature difference between original water and new water should not be too large.
- Due to the adsorption, metabolismof roots and algae activities, foreign matters will be covered on the surface of roots after a period of time. When changing water, they can be carefully washed away with water. Old dead roots should be removed when changing water.
- The water in the bottle should not be too much, and about 2/3 of the length of the root system should be immersed in water.
- Plant growth conditions are mainly water, nutrients and air. The oxygen content in water will gradually decrease with the growth of hydroponic plants. When it is reduced to a certain extent, the growth of plants will be affected by hypoxia. Although the oxygen in the air will continuously supplement to the water, the amount of oxygen supplement is far from enough. So be sure to change the water in time.
- The roots of plants that grow in water, on the one hand, absorb nutrients from the water, and on the other hand, discharge some organic substances, waste or toxins into the water, and deposit them in the water. And these organic matters in soil cultivation is mainly to dissolve the soil nutrients that are not easy to be absorbed by the root system, while the waste and toxins are distributed in the space of the soil or flow out from the hole in the bottom of the basin, and will not be absorbed by the root system and affect the normal growth of plants. And hydroponic containers have no bottom hole, these organic matter, waste or toxins are deposited in the water, it is easy to be inhaled by plants again, so repeated absorption, excretion, absorption, excretion vicious cycle, is not conducive to the normal growth of flowers and play a normal physiological function.
Fertilizer For Plants Growing In WaterWhen fertilizing hydroponic plants, attention should be paid to the amount of fertilizer. When it exceeds the concentration of fertilizer that plants can bear, it will cause harm to the plants in water. Also, pay attention to the use of professional hydroponic fertilizers. When growing plants in water, we should apply thin fertilizer frequently and fertilize when changing water to supply the nutrient.As we all know, the medium of the hydroponic plants is water, which only contains mineral inorganic nutrition. There is almost no amount of nitrogen, phosphorus and potassium required by plants, and the amount of trace elements in water is also greatly different from that in soil, which is far from meeting the normal needs of plant growth. Therefore, timely and reasonable fertilization for hydroponic flowers is necessary. It is undoubtedly a very important care measure. How to fertilize plants growing in water? What fertilizer for plants should be applied?Firstly, it uses a container that does not have a bottom hole when growing plants in water. Applying fertilizer in water is different from that in soil. The surface of soil particles can absorb part of the nutrient, and the excess nutrient can also be automatically lost through the hole in the bottom of the basin, so it has a certain buffer effect on the concentration of fertilization. But the fertilizer for plants in water is different. All kinds of nutrient elements in the nutrient solution that we apply are dissolved in water. As long as it slightly exceeds the tolerance of plants to the concentration of fertilizer, it will cause harm. Due to the above characteristics, it is very important to strictly control the amount and type of fertilizer of aquatic plants. Therefore, it is best to choose fertilizer specially for water plants and strictly in accordance with the use of instructions, avoiding excessive application and excessive concentration.Fertilizers for plants growing in water should be adjusted according to different circumstances, scientific.
This is because different plant species have different adaptations to fertilizer. Plant species with slender roots do not require large amounts of fertilizer and high concentrations. Additional, For foliage hydroponic plants, the fertilizer should be given priority to with nitrogen fertilizer, assist with phosphorus, potassium fertilizer, in order to ensure leaf hypertrophy, leaf surface is smooth, leaf color is pure. For plants species with color stripes or patches on the leaf surface, apply less nitrogen fertilizer appropriately, because it will make the leaf color fade or even disappear when nitrogen fertilizer is too much, and increase phosphorus and potassium fertilizer appropriately. For flowering plants, in the stage of flower bud differentiation and flower bud development, phosphorus and potassium fertilizer should be the main fertilizer, supplemented with nitrogen fertilizer appropriately, so as to avoid the adverse consequences of plant growth, excessive vegetative growth and reproductive growth, resulting in small flowers, few flowers, light color, and even no flowering.
- Apply fertilizer to different plant species
Generally in summer, the adaptability of plants to fertilizer concentration is reduced, so the concentration of fertilization should be reduced at this time, especially some of the plants that are afraid of the hot summer. When the plants in water are into a dormant state, the physiological activities in the plant body are slower, growth is also in a semi-stopped and stopped state, stop fertilizing at this time.
- Apply fertilizer in different seasons
Indoor lighting conditions are relatively poor. Although indoor plants are mostly shading tolerant, but in the long period without light, or in the case of a weak light for a long time, the growth of plants in water is not strong. In this situation, stop fertilization or apply less fertilizer and try to reduce the concentration of fertilizer.
1. For hydroponic plants, which have not yet adapted to the environment in the water, there will be yellow leaves or rotten root current. Do not fertilize at this time for ten days or so, fertilize after the plants in water adapting to the environment or taking a new root.2. Don't directly put urea in the water, because urea is a kind of artificial synthetic organic fertilizer. If the direct applying urea, not only the plant can't absorb nutrition, but also can make some harmful bacteria or microbial breeding quickly and cause water pollution。3. If there is rot root and water quality polluted caused by thick fertilizer, cut off the rot root of water plants quickly, wash the root and change water timely.
