Hydroponic plants fear green algae the most, don't panic, just follow along and it's guaranteed to work

In the hot season, growing a few hydroponic potted plants, with their crystal-clear transparency tinged with a bit of green, really lets us, frazzled as we are, enjoy a moment of coolness. But for many gardening friends, growing a good-looking hydroponic plant really isn't that simple, and the number one enemy is the green algae growing in the container, so how exactly should you deal with it and how should you prevent it? The following methods are sure to help you get through the tough times.

First, before dealing with green algae, we'd best understand why it appears and what harm it causes. Green algae is produced because hydroponic plants are exposed to sunlight for long periods, and plant growth cannot help but depend on sunlight, so in other words, the growth of green algae in water has an endless source of energy. At night, green algae compete with hydroponic plants for oxygen, causing the hydroponic plants to lack oxygen, which in turn triggers a series of problems such as root rot and yellowing leaves.

So how should you deal with it?

Simply put, it comes down to 9 words: "change water often, block the sun, disinfect the water." "Change water often" means the nutrient solution of hydroponic plants needs to be changed frequently, especially in summer, changing it 2 or 3 times a week is a very good choice. "Block the sun" means avoiding direct sunlight and avoiding creating conditions for green algae to survive.

As for "disinfect the water," this is what we often call "chemical therapy": you can put Lijunsha tablets into the water to disinfect it. Of course, if you don't have Lijunsha tablets, you can substitute roxithromycin tablets, with the same effect, but roxithromycin takes effect later, usually 1-2 days before obvious results appear. Also, generally a flowerpot with a diameter of 20cm needs one whole tablet, and the dosage of the medicine must be controlled well.

The three methods above mainly target the situation where green algae has already appeared in your hydroponic plants. Although effective, they only treat the symptoms, not the root cause. You should know that the root of dealing with this problem lies in "prevention" - without the interference of green algae, there is no problem that cannot be solved. As long as you do a good job of preventing green algae, you can grow hydroponic flowers very well.

Actually, the prevention methods are also very simple. The first point is that you must avoid direct sunlight; direct sunlight is the direct cause of green algae, so doing this well is the best prevention method. But this doesn't mean giving no sunlight at all - without sunlight, the plants will find it very hard to survive.

The second point is to change the water often. This method can very well avoid the appearance of green algae, and without a certain amount of time to accumulate, it's impossible for green algae to grow, so this method must also be remembered.
