How high should the water level be for hydroponic Phalaenopsis, and how should the water be changed?
Friends who have grown potted Phalaenopsis have probably also thought about trying hydroponic care, because it looks simpler, and when placed in the living room, water-grown plants always give a more elegant feeling.

So for hydroponic Phalaenopsis, what level should the water be controlled to? And how should its roots be protected later during water culture? The method is actually very simple. The key points of hydroponics are the four major elements: water level, water changing, root protection and environment. As long as these can be met, the orchid is guaranteed to get sick less often and still bloom abundantly.

First, let's talk about the container. Choose a glass vase (transparent). The advantage of doing this is that you can observe the state of the Phalaenopsis roots at any time. As for hydroponics, water level control is of course the most important thing. If it is a newly grown root, just let it touch the water surface by 1-2 cm. If it is already an old root, then it absolutely must not be fully soaked in water. Generally, the water level should not exceed one third of the total root length. In hot summer, because water evaporates faster, it can be slightly raised to half at this time.

Next, changing the water also has requirements. In spring and autumn, it is recommended to change the water once a week. In winter, when the temperature is low (you can appropriately add some warm water to the water to moderate it), it is recommended to change it once every two weeks. In summer, when the weather is hot, it must be changed once every 3 days. If you find that the water has become cloudy along the way, there is no need to wait until the third day; it must be changed right away. In addition, there is also a trick when changing the water: first pour out the old water, let the orchid roots dry for 4 to 6 hours, and once the roots are slightly dry, then add new water. This lets the root system breathe freely.

Then, in addition to the water level line, root care is also key. During care, if you find roots with rot or black spots, prune them immediately, and at all times keep only the healthy roots that are emerald green or dark red. And every time after using a cut, remember to apply some carbendazim to disinfect it. Newly grown water roots can be soaked in water for a long time, but the original aerial roots need regular "airing out" and cannot always be soaked.

Finally, the environment cannot be ignored either. Phalaenopsis likes an environment of 15 to 28 degrees. Usually place it in a spot with plenty of diffused light and good ventilation, and do not let the sun shine on it directly.
