Why do hydroponic flowers need to change water frequently?

Hydroponic flower culture is a very popular cultivation method for many flower friends. It is not only clean, but also very simple. Although the cultivation process is relatively simple, hydroponic flowers also need to change water frequently. The editor will tell you why.

Hydroponic plant

First, the conditions for plant growth are mainly water, nutrients and air, the water and nutrients of hydroponic flowers can absolutely guarantee their needs, and the oxygen content in water will slowly decrease with the growth of flowers, when reduced to a certain extent, it will have an impact on the growth of flowers, so it is necessary to supplement oxygen by changing water.

Second, the roots of hydroponic flowers grow in the water, on the one hand, absorb nutrients from the water, on the other hand, discharge some organic matter into the water, there are also wastes or toxins, and deposit in the water. When these organic compounds are cultivated in soil, they mainly dissolve the nutrients which are not easily absorbed by the roots, while the wastes and toxins are distributed in the soil space or flow out from the leaks at the bottom of the basin, which will not be absorbed by the roots and affect the normal growth of flowers. When flowers are hydroponically cultured, these organic compounds, wastes or toxins are deposited in the water and are easily absorbed by plants again, which is not conducive to the growth of flowers.

Third, hydroponic flowers often use nutrient fertilizer, in addition to part of the nutrients are absorbed by the root, the rest remain in the water, when the residual substance reaches a certain amount, it will do harm to the growth of flowers.

Fourth, hydroponic flower roots will produce a kind of mucus, which not only affects the absorption of nutrients in flower roots, but also pollutes the water.
