Sunlight is needed by all plants, and aquatic plants are no exception. They need sunshine to supplement, so that the leaves can absorb sunlight, synthesize nutrients and provide plants with growth. If you are in a place where you can't see the sun, the growth will be affected, the growth will become weak, and the leaves will start to turn yellow
Aquatic plants generally absorb nutrients from the water, so nutrient supplement is very important. In the natural state, they will be supplemented by leaves. If they are cultured at home, they can add nutrients to them from time to time, which can provide normal needs, but the amount can not be too much, or the plants will be difficult to bear, causing the consequences of burning roots.
We can choose the natural rainwater as the maintenance water quality, which can not only ensure the cleanness, but also contain a lot of trace substances. If the conditions do not allow, you can use standing water hydroponics, but pay attention not to use directly connected, standing for a period of time is conducive to the volatilization of chlorine.
Oxygen is indispensable for growth. The water used for hydroponics needs to be changed regularly, otherwise, there will be anoxia.
