Hydroponic plants are most afraid of green algae. Don't panic and follow as a guarantee.

In the hot season, raise a few hydroponic potted plants, translucent crystal with a little green, can really let the irritable us enjoy a moment of cool. But for many planting partners, raising a good-looking hydroponic plant is really not that simple, and the first enemy is the green algae growing in the culture container, so how to deal with it and how to prevent it? I'm sure the following methods will help you tide over the difficulties.

First of all, before dealing with green algae, we'd better know the cause and harm of it. Green algae are produced because hydroponic plants are exposed to sunlight for a long time, and the growth of plants has to rely on sunlight, so in other words, the growth of green algae in water has a continuous supply of power. At night, green algae will compete with hydroponic plants for oxygen, which will lead to hypoxia of hydroponic plants, which will lead to a series of rotten roots, yellow leaves and so on.

So how should we deal with it?

To put it simply, there are nine words: "change water frequently, block the sun, disinfect water". "changing water frequently" means that the culture medium of hydroponic plants needs to be changed frequently, especially in summer, where two or three changes a week is a good choice. "blocking the sun" refers to avoiding direct sunlight and creating living conditions for green algae.

As for "disinfectant", which is often referred to as "chemotherapy", Lijun sand tablets can be put into the water for disinfection. Of course, if there is no Lijun sand tablets can be replaced with roxithromycin tablets, the effect is the same, but roxithromycin effect will be relatively late, usually 1-2 days to appear obvious effect. In addition, the general diameter of the flowerpot in 20cm needs to put a whole grain, and the dosage of the drug should be controlled well.

The above three treatment methods are mainly aimed at your hydroponic plants have appeared the phenomenon of green algae, although effective, but not the root of the problem, we should know that the root of dealing with this problem lies in "prevention", without the interference of green algae, then there is no problem that cannot be solved. As long as you prevent green algae, you can grow hydroponic flowers.

In fact, the way of prevention is also very simple, the first point is to avoid direct sunlight, direct sunlight is the direct cause of green algae, so to do this is the best way to prevent. But this is not to say that there is no sunlight at all, without sunlight, it is very difficult for plants to survive.

The second point is to change water frequently, this method can avoid the emergence of green algae, it is impossible to grow green algae without a certain amount of time accumulation, so this method should also be kept in mind.
