What kind of water is used for hydroponic plants and the comparison of all kinds of hydroponic water

Abstract: the most important part of hydroponic plants is water, what is the best water for hydroponics? After multi-comparison, we get the ranking of water use in hydroponics: mineral water / pure water > magnetized water > Rain Water > river / lake water > self-made nutritious water > cold boiled water > tap water. Of course, this ranking is not absolute. Sometimes the water in the last place is better than the former, and what we are talking about here is the ranking under general conditions. Let's talk about the advantages and disadvantages of all kinds of water on hydroponic plants.

Mineral water / pure water

The front row of mineral water or pure water does not mean that its nutrition is the best for hydroponic plants. It should be said that Hua Yujun thinks it is most suitable for hydroponics.

First of all, it is relatively clean, hydroponic plants often have to look at the overall ornamental, mineral water in addition to trace elements there are no other impurities, high transparency, hydroponics as a whole is very beautiful.

Secondly, it is rich in trace elements and low in salt, which provides rich nutrition and won't hurt the roots.

The disadvantage is that the cost is relatively high, because hydroponic water can not be used to the end, at most every other month to change, if the hydroponic container is small and good, then the cost is a little high.

Magnetized water

Some flower friends will add a small magnet to the water, and the water quality will become magnetized water over a long period of time. Magnetized water contains less minerals and is clean enough. Hydroponic culture can promote plant metabolism, promote their cell growth, enhance stress resistance, and make hydroponic plant leaves healthy, green and shiny. It can also slow down the growth rate of algae in water and has a good effect on the roots of hydroponic plants.

The disadvantage is that magnets are not everywhere, and magnetized water is not readily available. Besides, Hua Yujun sometimes even thinks that it may be a little better than mineral water.

Rain Water

We all know that Rain Water is very suitable for watering flowers, because Rain Water is neutral water, basically free of toxins and minerals, high oxygen content and nitrogen nutrition carried from the air, which can make their leaves green and roots thick for hydroponic plants. it's a good water for hydroponics.

The disadvantage is that you can get it all the time, and you must accumulate it in advance on a rainy day, which means you have to rely on heaven for a living.

River / lake water

Rivers and lakes can also be called heavenly water. isn't there a poem that says that the water of the Yellow River comes from heaven? So it has the same advantages as Rain Water, with less minerals and hardness, and can carry some local micronutrients in the water, which is not bad for hydroponic plants.

The disadvantage is that there may be more impurities in the water, it is easy to breed some small organisms, green algae and so on, and the time interval for changing water becomes shorter. And the water quality of the river may be polluted by a variety of other chemicals, sometimes can not rest assured to use, it is best to save a few days before use.

Self-made nutritious water

This is more complex, self-made nutrition water can be rice water, beer water, tea, milk water, vitamin water, etc., more suitable for hydroponics with other water. Water is rich in nutrients, which can promote the growth of hydroponic plants and make them strong and beautiful in a short time.

The disadvantage is that it can not be used for a long time, it can only be used once after a while, and the concentration ratio is not easy to grasp, and it may burn roots if you are not careful, which is not good for plants. In addition, self-made nutritious water has been fermented, and the water will stink over a long time, which will greatly reduce the ornamental quality of hydroponic plants.

Cold boiled water

Is what we commonly call cool boiled water, some people worry that boiled water will make nutrients disappear, it is true that the nutrients in the water will be damaged to varying degrees after heating, it is best to use with nutrient solution. And cold boiled water after the impurities and calcium content will become less, bacteria can also be effectively reduced, high cleanliness. Hydroponic cultivation of plants with cold boiled water can keep plant roots white and beautiful for a long time, which is better than tap water.

The disadvantage is that the oxygen content in the water is low, which is easy to make the plants lack oxygen. If there are conditions, you can use it after filling the water with oxygen. If not, shake the water in the flowerpot before using it to increase the oxygen content. It is best to mix it with other water.

Tap water

Tap water is low in minerals and clean, so it is the most convenient to obtain hydroponic water, and the tap water treated by precipitation can still let plants grow well.

The disadvantage is obvious, it contains chlorine, which is harmful to plants. Rest for at least 2 days before use.

The above is some analysis of the advantages and disadvantages of hydroponics, if you plan to do hydroponics for plants, you might as well refer to it and make a comparison. In addition, domestic waste water such as laundry water, dishwashing water contains harmful substances such as chlorine and alkali, and groundwater such as well water contains more minerals, which are not suitable for hydroponics. No matter what kind of water is used, replace it regularly, and remember to clean the roots and keep the roots and containers clean.

How often do hydroponic plants change water? how to replenish water for hydroponic plants?

Hydroponic plants need to replenish water in time due to the transpiration of leaves and the evaporation of water in containers. If the water is not changed for a long time, the contents of the container are easy to breed bacteria and easily cause the death of plants. So how often do hydroponic plants change water? How to replenish and change water for hydroponic plants? Let's take a look.

How often do hydroponic plants change water?

Generally, the time for changing water is 5-7 days. But the change of water depends on the season, just hydroponic flowers, require 1-2 days to change water once. The summer plant growth is exuberant, the temperature is high, the water is easy to deteriorate, the time should be shortened. In winter, most of the plants are semi-dormant or dormant, the temperature is lower, and the interval between changing water can be longer. Generally speaking, the interval between changing water is shorter, which is beneficial to plant growth.

How to replenish and change water for hydroponic plants

Generally speaking, it is easy to use pure water as hydroponics. Pure water belongs to desalted water and has low salt content, so it is suitable for hydroponic flowers. In addition to low salt content, pure water has the advantages of good transparency and no pollution, so it is the most ideal water for hydroponic flowers.

In addition, qualified drinking tap water can also be used for hydroponic flower culture, but tap water disinfection commonly used liquid chlorine, excessive chlorine is harmful to flower roots, in order to release chlorine, it needs to be placed for a period of time before use.

When changing water, the roots should be cleaned, clean water can be used to wash away the mucus on the roots, and some of the rotten roots and old roots that have lost their absorptive capacity can be cut off. After the container has been used for a period of time, the wall of the container will adhere to a precipitate, and it is also easy to grow moss, which should be cleaned when changing water.

There is also a small detail, when adding water to the container, all the roots can not be immersed in the water, the roots are rotten. It is best to expose more than 1/3, so that the roots can absorb not only dissolved oxygen in water, but also oxygen from the air.

Why should we keep replenishing water for plants

The control of the water level of water-raised flowers should be low rather than high, 1/3 to 1/2 of the roots should be submerged into the water, and the rhizome of the plant should be flooded. In the process of water culture, plants will consume part of the water through the transpiration of leaves, and the container will also evaporate some water through the opening. Therefore, after being cultured for a period of time, the water content in the container will decrease and the water level will drop. replenish water at the right time. Replenishing water can increase the content of oxygen ions in the root environment, which is beneficial to the development of the root system.

Why change water for plants on a regular basis

Changing water for hydroponic flowers regularly or irregularly is also one of the key points of plant management in order to keep hydroponic solutions fresh. Training water can be used by springs, wells, etc., and tap water should be used after a day or two. The time of changing water can be determined according to the specific conditions of culture. generally, the water can be changed every 3-5 days in spring and summer, and every two weeks in autumn and winter. If the water quality is pure and clean, and the plants and roots grow well, you can also prolong the water exchange time and only need to replenish the evaporated water.

What is the culture of hydroponic plants?

Speaking of hydroponic plants, I think we are no strangers. Most of us understand that hydroponics, as the name implies, is to plant plants and flowers directly into the water for cultivation and breeding. Is that true? Let's find out: the most scientific explanation is that hydroponic plants and flowers adopt modern bioengineering technology and use physical, chemical and bioengineering means to domesticate ordinary plants and flowers so that they can grow in water for a long time. And the formation of a new generation of high-tech agricultural projects.

The plants that can be hydroponically cultured are tortoise-backed bamboo, Milan, gentleman orchid, camellia, rose, jasmine, rhododendron, evergreen, violet, Phalaenopsis, inverted golden bell, five-needle pine, rubber banyan, Brazilian iron, begonia, ferns, palms, etc., as well as various foliage plants, such as tufted taro, silver-bract taro, fire crane flower, Guangdong hanging orchid, Yinbian evergreen.

There are more than a hundred kinds of lotus palm, hibiscus palm and other kinds of orchid, Paphiopedilum, crab claw orchid, rich bamboo, pineapple, silver leaf chrysanthemum, Brazilian wood, ivy, colored leaf grass and so on. Basically, plants that can be planted in the soil can be hydroponically cultivated, but a small number of plants that prefer a dry environment are not suitable for hydroponics.

Culture methods of hydroponic flowers:

So much has been said before, isn't it a bit messy? Well, the editor doesn't make these bends around, so let's hit the nail on the head: how do these hydroponic plants grow?

Generally, it is a good policy to transplant it directly into the hydroponic basin. The specific practices are as follows:

1. Take off the pot: tap around the flowerpot with your hand, and the whole plant can be removed from the pot after the soil is loosened.

2. Remove the soil: first gently remove the excess soil with your hands.

3. Washing: rinse the soil or matrix glued to the root with water.

4. Cut the planting basket: if the head of the plant is too large and the aperture of the planting basket is too small, the hole of the planting basket needs to be enlarged to facilitate planting.

5. Add nutrient solution: add the prepared nutrient solution to the container. Large seedling planting: insert the root system of the plant from the planting basket and be careful not to hurt the root.

6. Fixed: fixed with sponge, hemp stone or Yuhua stone (other solids can also be used).

7. Finished product: check whether the finished product is fixed.

The preparation of nutrient solution commonly used in water propagation and seedling production:

Hydropropagation uses water as the medium, and there are no nutrient elements needed for plant growth in the water, so it is necessary to prepare a certain nutrient solution for plant rooting and seedling growth before transplantation. The selection of nutrient solution formula is the key to the success of hydroponics, and the nutrient solution formulations required by different plants are different, so we must prepare the nutrient solution according to the needs of plants in water culture.
