1、 How

Lay 1 to 2 cm of water grass mud in the fish tank in advance, and then add some water to the fish tank. The water volume is not too much, and the soil can be soaked. Then sprinkle the seeds evenly on the water, grass and mud. Pay attention not to cover the seeds with water, grass and mud. After the seeds are sprinkled, cover the fish tank with plastic wrap, and then poke a few holes on the plastic wrap to keep the temperature stable. Keep the temperature at 25 to 30 ℃. To keep the sun full, they will begin to sprout almost three days later. Sprinkle water every day to keep the water, grass and mud moist and keep the light, In about five days, water and grass will basically grow out

2、 Precautions

When the water plants grow, you can slowly fill the fish tank with water. When adding water, you should slowly add water along the tank wall to avoid overturning the soil bed
