How to cultivate hydroponic plants how to change water for hydroponic plants

Nowadays, household plants are entering more and more families, and hydroponic plants are more popular because of their clean sanitation and simple maintenance. But there are still a lot of people who don't know how to grow hydroponic plants? How do hydroponic plants change water? Let's answer these two questions briefly.

How to grow hydroponic plants

I. Temperature

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

II. Light

Scattered light predominates. What is scattered light? It is natural light that comes in from places such as windows and scatters naturally indoors. General plant growth as long as there is appropriate light on the line, not necessarily to the sun, in summer, but also try to avoid direct sunlight.

III. Nutrient solution

Generally, we can use the special nutrient solution for hydroponic culture sold on the market. According to the instructions, we can prepare the appropriate concentration, such as diluting 400 times or 1000 times. Don't get the ratio wrong. When preparing, tap water should be placed for two hours to half a day, and after its temperature is close to room temperature and chlorine in the water volatilizes completely, concentrated nutrient solution is added according to proportion to form nutrient solution for cultivating hydroponic plants.

IV. Water change

Water change refers to changing the water added with nutrient solution in the bottle. Under normal circumstances, the water is changed once every 5-10 days in spring and autumn; the water is changed once every 5 days in summer; and the water is changed once every 10-15 days in winter (after the tap water is placed for half a day, the concentrated nutrient solution is added according to the proportion).

Water change is to ensure the oxygen supply in the water, fresh water contains more oxygen, plants will grow healthier, if you do not change water for a long time, plants can also persist for a period of time, such as sometimes we go on business or vacation, ten days and a half months or even a month away from home, soil cultured plants have long been unable to stand, died, and hydroponic plants as long as you add more water, or can persist; However, if the time is too long, the water in the bottle is not fresh or deteriorated, which will affect the growth of hydroponic plants, and in serious cases, it will also cause its death.

Note: When changing water, expose half or one-third of the roots of the plant.

V. Cleanliness

Rinse plant roots and containers with clean water every time you change water, trim dead branches, leaves and rotten roots. Under normal growth conditions, hydroponic plants will regularly rot part of the roots and grow new roots, so when you find rotten roots, don't panic first, use sterilized scissors (disinfected with alcohol cotton) to prune the rotten roots, and sometimes you can prune some old roots to promote the growth of new roots (note: under the guidance of professionals). But be careful not to hurt aquatic roots, otherwise it will affect the growth of plants.

The roots of hydroponic plants, those white and tender roots above are aquatic roots, some grow directly from the base of the stem, some grow from the main root, they are responsible for the absorption function of the plant, must not hurt them.

VI. Moisturizing

There is very little moisture in the air in winter, especially in the north, and the indoor is very dry, which is unfavorable for the growth of plants, so daily spray leaves with clean water to maintain humidity, and spray water twice a day.

How to change water for hydroponic plants

1. Water change time:

The water change time is usually 5-7 days. However, water change depends on seasonal conditions. Flowers that have just been hydroponic require 1-2 days to change water. Summer plants grow vigorously, the temperature is high, the water is easy to deteriorate, the time should be shortened. In winter, most plants are in semi-dormancy or dormancy state, the temperature is low, and the interval time of changing water can be longer. Generally speaking, the water change interval is shorter, which is beneficial to plant growth.

2. Cleaning of roots and containers:

When changing water, the root system should be cleaned. The mucus on the root system can be washed away with clean water, and some rotten roots and old roots that have lost their absorption capacity should be cut off. After using the container for a period of time, the wall will adhere to some sediments, and it is also easy to grow moss. It should also be cleaned when changing water.

Depth of water:

In hydroponic flowers, often the roots immersed in water, but this method is inappropriate, the best water should not be added too much, most of the roots are fully immersed in water, a small number of roots exposed in the air, so that the roots can absorb dissolved oxygen in water, but also from the air.
