While enjoying the convenience and beauty brought by hydroponics, many flower lovers also encounter a headache problem - green algae grow in hydroponic containers. Green algae not only affect the appearance but may also have an adverse impact on the growth of plants. So, in the face of this problem, how should we solve it?
The growth of green algae is often related to excessive light intensity or long illumination time. Therefore, adjusting the light is the key to controlling the growth of green algae. For hydroponic plants that require sufficient light, consider using shading nets or adjusting the placement to avoid direct sunlight shining on the water surface for a long time. At the same time, regularly check the light requirements of plants to ensure that it meets the growth needs without causing an overgrowth of green algae.
Regularly changing the hydroponic solution is an effective measure to keep the water quality clean and prevent the growth of green algae. It is recommended to change the water at least once a week and thoroughly clean the inner wall of the container and the attachments on the root system when changing the water. When changing the water, you can use clean water to rinse the roots to remove residual nutrients and impurities and reduce the nutritional source for the growth of green algae.
If the green algae problem is relatively serious, you can consider using a special algicide for treatment. There are many kinds of algicides for hydroponic plants available on the market. When using them, operate correctly according to the instructions to avoid harming the plants. It should be noted that although algicides are effective quickly, long-term use may have a certain impact on the environment. Therefore, it is recommended to combine other methods for comprehensive prevention and control.
In some cases, you can try to introduce natural enemies of green algae such as snails or shrimps to control their growth. These organisms can effectively eat green algae. However, it should be noted that before introducing them, make sure they will not harm the plants.
Poor ventilation and high humidity are also favorable conditions for the growth of green algae. Therefore, in daily maintenance, keep the air around hydroponic plants circulating and avoid being in a closed and humid environment for a long time. At the same time, also pay attention to controlling the indoor humidity to prevent excessive humidity from causing green algae to breed.
In addition to the green algae problem, hydroponic plants may also be infested with insects. These pests will not only affect the ornamental value of plants but may also have a serious impact on the growth of plants. So, what causes insects to grow on hydroponic plants? And how should we prevent and control them?
First, unclean water quality is easy to breed bacteria and parasites, providing a living environment for pests. A closed and humid environment is conducive to the reproduction of pests. Secondly, excessive nutrients will not only cause plants to grow excessively but may also attract pests to come for food. Newly added plants or containers may carry pests or pathogens.
So for these situations, we need to change the water regularly and clean the container and root system to avoid water pollution. Keep the air around hydroponic plants circulating and reduce humidity and temperature. Fertilize reasonably according to the growth needs of plants to avoid excessive nutrients. Regularly check whether there are signs of pests on plant leaves and roots. Once found, deal with it immediately. Use natural enemies such as predatory mites and ladybugs to control the number of pests. When the pest infestation is serious, pesticides can be used for spraying or soaking treatment.
