1、 Can I raise it underwater

Pennisetum can be cultured underwater, but with the continuous growth of plants, it will grow out of the water sooner or later. It is easy to rot in water, so it needs to be cleaned frequently. If there are fish under the water, it will be easy to grow green algae. It needs to change the water properly. This kind of breeding method is mostly raised indoors. It is also inconvenient to move to the outside regularly to bask in the sun. Therefore, it is necessary to use the method of artificial lighting to make the plants receive as much light as possible

Note that if fish are raised underwater at the same time, try not to raise small fish species that bite the roots of plants. Some fish and plants raised together, will often bite its roots, resulting in plant death, so choose a good variety. And don't keep more than one

2、 Can it grow

It can also grow underwater, but the plants are not beautiful. Because its stem will become long and straight, and grow very fast. If you don't pay attention, it will burst. However, if the light is properly controlled, its growth speed can be slowed down. Many flower friends say that the growth of plants will be poor if they are raised underwater, which is the reason why there is no sunshine for a long time
