In recent years, hydroponically cultivating Phalaenopsis has become increasingly popular among flower enthusiasts as a unique cultivation method. During the hydroponic cultivation process, the management of the water level is particularly important, especially to avoid the hazards caused by a too high water level.
Hazards of a too high water level when hydroponically cultivating Phalaenopsis
Obstructed root respiration: The roots of Phalaenopsis are aerial roots and require sufficient air for respiration. When the water level is too high, most or even all of the roots are submerged in water, resulting in obstructed root respiration. If this situation persists for a long time, the roots will rot due to lack of oxygen, seriously affecting the growth and health of the Phalaenopsis.
Increased risk of diseases: A too high water level also easily keeps the roots in a moist environment, which is a hotbed for the growth of pathogens. Once pathogens invade the roots, it will lead to the occurrence of root diseases, such as root rot. These diseases not only affect the growth of the Phalaenopsis but may also lead to its death.
Affected nutrient absorption: A too high water level will also affect the nutrient absorption of the roots of the Phalaenopsis. In an oxygen-deficient environment, the metabolic activities of the roots will slow down, resulting in a decrease in the ability to absorb nutrients. As a result, the Phalaenopsis will show phenomena such as poor growth and yellowing leaves due to insufficient nutrients.
In order to avoid the above hazards, the water level when hydroponically cultivating Phalaenopsis needs to be strictly controlled. So, what is the appropriate water level?
Initial water level: In the initial stage of hydroponic cultivation, since the roots of the Phalaenopsis need to adapt to the new growth environment, the water level can be slightly higher, but generally should not exceed half of the roots. This can ensure that the roots have enough water for metabolic activities, and at the same time, it will not affect the respiration due to a too high water level.
Water level in the stable period: After entering the stable period, the roots of the Phalaenopsis have adapted to the hydroponic environment, and the water level can be appropriately reduced at this time. Generally speaking, the water level can be maintained at about one-third of the roots. This can not only ensure that the roots have enough water and air for normal physiological activities but also avoid the hazards caused by a too high water level.
Water change and water level adjustment: During the hydroponic cultivation process, it is also necessary to change the water regularly and adjust the water level. Changing the water can keep the water quality clean and prevent the growth of pathogens; adjusting the water level can be flexibly adjusted according to the growth situation of the Phalaenopsis. Generally speaking, in the initial stage of hydroponic cultivation, the water can be changed and the water level adjusted once a week; after entering the stable period, the water can be changed every two weeks or even longer, and the water level can be adjusted according to the actual situation.
The management of the water level when hydroponically cultivating Phalaenopsis is of vital importance. A too high water level will bring hazards such as obstructed root respiration, increased risk of diseases, and affected nutrient absorption. Therefore, during the cultivation process, it is necessary to strictly control the water level and make flexible adjustments according to the growth situation of the Phalaenopsis. Only in this way can we ensure that the Phalaenopsis grows healthily and vigorously in the hydroponic environment.
