How to change the water for hydroponic plants? Detailed steps

  In recent years, growing hydroponic plants at home has increasingly become a trend. Not only is managing hydroponic plants simpler and more convenient than soil culture, but it also keeps the space cleaner, and it can likewise achieve the effect of beautifying the home. So growing green plants hydroponically is increasingly favored by many families. However, water culture is after all different from soil culture. Soil plants generally need repotting once a year, while hydroponic plants need frequent water changes. Compared with soil culture, hydroponics seems a bit troublesome in this respect, but as long as you get used to it, you won't find it troublesome anymore. Don't you agree?

  It's just that the oxygen content in water is inherently very low, and after part of it is absorbed by the plant's root system, oxygen urgently needs to be supplied. If you don't change the water for the plants regularly, it easily leads to oxygen deficiency in the plants. Moreover, after the harmful substances that accumulate in the water over a long time are absorbed by the plants, they easily trigger diseases, and the plants will show poor growth, and in severe cases may even die. So how do you change the water for hydroponic plants? Below, the editor will introduce the water-changing steps for hydroponic plants.

  1. Determine the water-changing time

  Normally, the water-changing cycle for hydroponic plants is 1 week, but specifically it also needs to be decided according to seasonal changes. For plants that have just been set up for hydroponics, it is recommended to change the water once every 1 or 2 days; summer is often the vigorous growth period for plants, with higher temperatures, and water quality easily changes, so the water-changing cycle should be appropriately shortened; when winter arrives, plants usually enter dormancy or semi-dormancy because the temperature is too low, so the water-changing time should not be too frequent, and the water-changing cycle needs to be appropriately extended. Under normal circumstances, shortening the water-changing time for hydroponic plants is relatively more beneficial to plant growth, because not only is the water quality less likely to deteriorate, but fresh nutrients can also be replenished for the plants in time.

  2. Do a good job of cleaning

  Before changing the water for hydroponic plants, you should first take the plant out, clean off the sticky matter on the plant's root system, and at the same time remove the rotten parts on the root system or old roots and diseased, weak roots that have completely lost their absorption function. Cleaning the root system can enhance the plant's ability to absorb nutrients in the clean new solution and promote healthy plant growth.

  In addition, besides cleaning the plant's root system, the container also needs to be cleaned thoroughly. This is because after the container has been used for a period of time, some sediment will stick to its inner wall. If it is not cleaned off in time, it is easy for moss to grow, and under certain conditions it may breed bacteria, thus bringing diseases to the plant. So when changing the water for the plant, the container also needs to be thoroughly cleaned at the same time.

  3. The water-changing amount should be moderate

  Many gardening friends like to completely immerse the root system in water when changing the water for hydroponic plants, but as we know, plants are also living things and also need to breathe. Besides being able to absorb a certain amount of dissolved oxygen in water, plants more need to absorb oxygen from the air. So when we change the water for the plants, it is recommended not to completely submerge the root system in water, and to leave part of the root system in the air. This helps the plant's root system absorb more oxygen and lets the plant grow better. So when filling the container with water, keep a distance between the water surface and the upper part of the plant's root system.

  Of course, in order to make the plant grow more luxuriantly and quickly, we can also buy some nutrient solution from the market. When changing the water for the plant, we can add a few drops of nutrient solution, which is very important for the growth of hydroponic plants.
