The crown grass has a larger strain, and it is not easy to fix it with a thinner rope. In order to facilitate the fixation of plants in the fish tank, gravel with a thickness of about 4 mm is usually used as a substrate for planting. Before planting, a layer of substrate about 7 centimeters thick should be laid in the fish tank, and half of the water should be filled in the tank, and finally the plants should be planted in it.
When the plant grows a little longer, in order to deepen the fixation, nylon thread can be used to fix it. Sometimes iron wire can also be used, but it needs to be matched with suitable water quality to prevent iron wire oxidation. In addition, the water flow in the tank is reduced during management, and the sand at the bottom is often thickened to prevent the plants from floating.
You don't need water grass mud for planting crown grass. Because of the large strain of the plant, planting with water grass mud is not conducive to the fixation of the plant. So they usually use ceramic or gravel as a substrate to plant it. When planting, we should pay attention to adjusting the quality of water. The PH value of water should be controlled between 6.5 and 7.2, and the hardness should not be too high. If the water quality is not suitable for their growth, they may not be able to adapt, resulting in rotten leaves, yellow leaves and other problems. This is especially important for plants that have just moved from soil to hydroponics.
