Hydroponic cultivation of Phalaenopsis is both aesthetically pleasing and environmentally friendly. However, the maintenance and management in the initial stage are of vital importance, especially in terms of watering and sunlight exposure.
Watering Management of Hydroponic Phalaenopsis in the Initial Stage
Judgment of the watering timing: In the initial stage of hydroponic Phalaenopsis cultivation, grasping the watering timing is particularly crucial. You can determine whether it is time to water by observing the color of the roots, the water vapor on the pot wall, and weighing the pot. When the roots turn white, the pot wall is dry without water vapor, and the pot is light in weight, it is the best time to water. In addition, Phalaenopsis in the vigorous growth period has a relatively large demand for water, so the amount of watering can be appropriately increased; while during the dormant period, watering should be reduced to keep the planting medium dry.
Watering methods: There are mainly three watering methods for hydroponic Phalaenopsis: the normal watering method, the water absorption method, and the pot soaking method. The normal watering method is suitable when the roots are slightly white. Slowly pour in an appropriate amount of water, and be careful to avoid the stem. The water absorption method is to place the flower pot in water and let the sphagnum moss absorb water by itself. However, it should be noted to avoid making it completely wet to prevent root rot. The pot soaking method is suitable when Phalaenopsis is extremely short of water and the medium has good water permeability. Immerse the whole pot in water and take it out after the water has penetrated.
Care after watering: After watering, place the Phalaenopsis in a well-ventilated position to allow the excess water to dissipate as soon as possible and avoid root rot. At the same time, regularly spray water on the leaves to increase humidity, so as to keep the leaves of the Phalaenopsis green and plump.
Sunlight Exposure Management of Hydroponic Phalaenopsis in the Initial Stage
Sunlight exposure requirements: Phalaenopsis has certain requirements for sunlight exposure, but direct sunlight should be avoided in the initial stage. In the initial stage of hydroponic cultivation, place the Phalaenopsis in a position with sufficient diffused light, such as near a window but away from direct sunlight. This can not only meet the light requirements of the Phalaenopsis but also prevent the leaves from being burned by strong light.
Adjustment of the sunlight exposure time: As the Phalaenopsis grows, the sunlight exposure time can be appropriately adjusted. In spring and autumn, when the sunlight is relatively mild, place the Phalaenopsis by the sunny window so that it can receive sufficient sunlight. In summer, move the plant to an environment with sufficient scattered light to avoid strong direct sunlight. In winter and early spring, since the sunlight is weak, it can be exposed to direct sunlight, and a fluorescent lamp can be used to supplement the insufficient sunlight.
The relationship between sunlight exposure and temperature: It should be noted that sunlight exposure is closely related to temperature. The optimal growth temperature of Phalaenopsis is 15-28°C. When the temperature is lower than 15°C, its roots will stop absorbing water, resulting in physiological water shortage of the plant. Therefore, when managing sunlight exposure, attention should also be paid to temperature changes to ensure that the Phalaenopsis is in a suitable growth environment.
The watering and sunlight exposure management of hydroponic Phalaenopsis in the initial stage are of great significance. In terms of watering, it is necessary to judge the watering timing according to the color of the roots, the water vapor on the pot wall, and the weight of the pot, select an appropriate watering method, and pay attention to the care after watering. In terms of sunlight exposure, direct sunlight should be avoided, and the sunlight exposure time and intensity should be adjusted according to seasonal changes. At the same time, pay attention to the impact of temperature changes on the growth of Phalaenopsis. Through scientific and reasonable watering and sunlight exposure management, I believe that your hydroponic Phalaenopsis will surely thrive.
