1. Temperature

It is necessary to maintain a suitable temperature condition for the hydroponics of Pennisetum. It likes to be warm, so the surrounding temperature should be maintained between 16-24 ℃, so that it can always maintain a better growth state, so as to grow better

2. Water quality

Water is the substrate for its growth. The use of good water is also good for its growth. Specifically, it is recommended to use purified water, because it does not contain other sundries and will not damage the plant. Tap water can also be used if it is not convenient to obtain, but it needs to be connected to the container the day before use and placed for another day. In this way, some of the gases that are bad for the plant can volatilize

3. Nutrient solution

Because there are few nutrients in the water, it is difficult to meet the needs of plant growth. Therefore, it needs to add nutrient solution 2-3 times a month to supply it with nutrients. However, in winter, because it doesn't grow fast and doesn't need much nutrients, it needs to reduce the frequency of application

4. Precautions

Because it grows very fast in the growing season and will soon fill the pot. Therefore, it should be trimmed or divided into pots in time to prevent its leaves from blocking each other and affecting the light
