As an elegant and unique indoor ornamental plant, the hydroponic Phalaenopsis cannot grow without suitable light conditions. Light is an important source for plants to carry out photosynthesis and accumulate nutrients, which is also crucial for Phalaenopsis. So, what kind of light does the hydroponic Phalaenopsis need?
Phalaenopsis needs sufficient but not too strong light. In the hydroponic environment, the light time of Phalaenopsis is preferably controlled between 2 and 2.5 hours per day, ensuring that the sunlight directly shines on the plant through the glass. Such light intensity and time can not only meet the growth needs of Phalaenopsis but also avoid the leaves being burned by strong light. At the same time, the light time should not be less than 1 hour, otherwise, it will affect the growth of the aquatic roots. It is worth noting that the light can be carried out once a week and then paused for a week to simulate the natural sunlight changes, which helps Phalaenopsis better adapt to the environment.
To provide a suitable light environment, the hydroponic Phalaenopsis can be placed in a well - ventilated place indoors to avoid direct sunlight. If the temperature is high and the sunlight is strong at noon, the window can be opened appropriately for ventilation to let Phalaenopsis receive some soft scattered light, while maintaining a suitable room temperature. Such an environment helps Phalaenopsis maintain a healthy state and promotes the leaves to be green and the flowers to be bright.
During the growth process of the hydroponic Phalaenopsis, the leaves may turn yellow sometimes. This is usually caused by various factors. Let's analyze them one by one and find out the solutions.
Improper light: Both too strong and too weak light can cause the leaves of Phalaenopsis to turn yellow. Long - time exposure to the sun will burn the leaves, making the water in the leaves evaporate too quickly and turn yellow. Insufficient light will affect the photosynthesis of plants, resulting in insufficient nutrient accumulation, and the leaves will gradually turn yellow. The solution is to place Phalaenopsis in a well - ventilated place to avoid direct sunlight, ensuring the light time and intensity are moderate.
Improper water management: The hydroponic Phalaenopsis has high requirements for water. Both insufficient and excessive water can cause the leaves to turn yellow. Long - time without changing water, too high water temperature, or poor water quality will lead to the reproduction of bacteria, affecting the health of the plant. The solution is to change the water regularly, usually once a week, and ensure there is no residue in the water bottle. At the same time, the amount of watering should be reasonably controlled to avoid waterlogging at the roots.
Inappropriate temperature: Phalaenopsis is a tropical plant and has high requirements for temperature. Both too high and too low temperatures will affect its normal growth and cause the leaves to turn yellow. The solution is to place Phalaenopsis in an environment with a suitable temperature. Avoid high - temperature exposure in summer and keep warm in winter, controlling the room temperature between 15 and 20 degrees Celsius.
Other factors: Besides light, water, and temperature, factors such as excessive fertilization and root rot can also cause the leaves of Phalaenopsis to turn yellow. Excessive fertilization will burn the roots and affect nutrient absorption. Root rot will lead to a decline in the overall health of the plant. The solution is to stop fertilizing immediately and check the root condition. If there is rot, it needs to be trimmed in a timely manner, disinfected, dried, and then replanted.
The hydroponic Phalaenopsis needs suitable light conditions, as well as reasonable water and temperature management, to maintain healthy growth. During the maintenance process, the state of the plant should be closely monitored to timely discover and solve problems.
