Why hydroponic flowers need water changes and root washing.

In current hydroponic flower management techniques, changing the water and washing the roots is an important part of ensuring good growth of hydroponic flowers. So why do hydroponic flowers need water changes and root washing? This reason is well worth exploring.

First, the conditions for plant growth are mainly water, nutrients and air. The water and nutrients in hydroponic flowers can absolutely guarantee their needs, but the oxygen content of the water will gradually decrease as the flowers grow. When it decreases to a certain level, it will affect the growth of the flowers due to lack of oxygen, so the water must be changed to replenish new oxygen.

Second, the roots of hydroponic flowers growing in water absorb nutrients from the water on the one hand, and on the other hand release some organic substances into the water, as well as waste or toxins, which settle in the water. During soil cultivation, these organic substances mainly dissolve nutrients in the soil that are not easily absorbed by the roots, while waste and toxins are distributed in the spaces of the soil or flow out through the drainage holes at the bottom of the pot, and will not be absorbed by the roots to affect the normal growth of the flowers. But hydroponic containers have no bottom holes, so these organic substances, waste or toxins all settle in the water and are very easily taken into the plant body again. This vicious cycle of repeated absorption, excretion, reabsorption and re-excretion is very unfavorable to the normal growth of the flowers and the performance of their normal physiological functions.

Third, of the nutrient fertilizer often added to the water for hydroponic flowers, apart from the part of the mineral elements absorbed by the roots, the rest remains in the water. When the residual substances reach a certain amount, they will also cause certain harm to the flowers. Fourth, the roots of hydroponic flowers that grow in water for a long time will produce a kind of mucus. When there is a lot of mucus, it not only affects the absorption of nutrients by the flower roots, but also pollutes the water.

Due to the above three reasons, hydroponic flowers must be managed with regular water changes and root washing.
