How often should water be changed for hydroponic plants?

Water change refers to the replacement of water with nutrient solution in the bottle, under normal circumstances, change the water once every 5-10 days in spring and autumn;

Change the water about once every 5 days in summer;

Change the water once every 10-15 days in winter (after the tap water is left for half a day, the concentrated nutrient solution is added in proportion).

The water change is to ensure the oxygen supply in the water, the fresh water contains more oxygen, the plant will grow healthier, if the water is not changed for a long time, the plant can also persist for a period of time, such as sometimes everyone goes on a business trip or goes on vacation, ten days and a half month or even a month away from home, the soil culture of the plant has long been unbearable, a life is whimpering, and the hydroponic plant as long as you add more water, you can still persevere;

But if it is too long, the water in the bottle is very unfresh or spoiled, which will affect the growth of the hydroponic plant, and in severe cases, it will also cause its death.

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

Generally, the water change time is 5-7 days. However, the water change depends on the season, and the flowers that have just been hydroponic require the water to be changed once every 1-2 days. In summer, plants grow vigorously, the temperature is high, the water is perishable, and the time should be shortened.

In winter, most plants are semi-dormant or dormant, with lower temperatures and longer intervals between water changes. In general, the shorter intervals between water changes are beneficial to plant growth.

Changing the water of hydroponic flowers regularly or irregularly is also one of the key points in managing plants to keep the hydrotrophic solution fresh. Cultivation water can be used spring water, well water, etc., and tap water should be left for a day or two before use. The water change time can be determined according to the specific situation of the culture, and the water can be changed every 3-5 days in spring and summer; Change the water every two weeks in autumn and winter.

If the water is pure, clean, and the plants and roots are growing well, the water change time can be extended to replenish the amount of evaporated water.

Basically, when growing plants in water, it is better to change the water once every 10-15 days. When the plant is raised in water, if it is just raised in water, the new root system has not grown out at this time, and the water can be changed more frequently, at this time, the water can be changed once in 3-4 days, and the water plant can grow out of the root system in about a week, and the plant gradually grows strong. After that, when changing the water, you can add some Bika water-soluble fertilizer.

The temperature is between 15 degrees Celsius and 28 degrees Celsius, and the nutrient solution is changed every 7 to 10 days for the hydroponic flowers with strong branches and leaves.

When the temperature exceeds 30 degrees Celsius, most flowers are dormant or semi-dormant, and the physiological metabolism is slow. It also takes 7 to 10 days to change the water with new water.

When the temperature drops below 28 degrees Celsius, replace the tap water with new water every 15 to 20 days, combined with a water change, with a slow cleaning of the utensils, and rinse the roots. Because the water temperature is low in winter, germs do not multiply in large numbers, and the flower roots are not perishable.

Hardy flowers, such as ivy, vine, etc., still grow well at 5 degrees Celsius to 7 degrees Celsius.

Basically, you have to change the water every day, prune every two days, about three centimeters off each time, often spray with a watering can, and if there are signs of wilting, cut the branches very short, maybe you can salvage it.

Observation method This method is suitable for flowers with general water requirements, do not rush to water the flowers you buy, first observe carefully, remember the normal appearance of the leaves, such as the smooth sailing (white crane taro) in the picture below.

If there is a shortage of water, it will be shown below.

At this time, you can water it thoroughly, and after a long time, you will find out how often this pot of flowers should be watered in the environment of your home.
