Before the plants have sprouted, a net structure will be watered for five minutes; in the second phase, for half that time, and in the last phase for only thirty seconds. "This is because the leaves are growing, and blocking the surface of the soil. The s can't get in, and the soil stays wet, so it doesn't need too much water."
菜苗未發芽前，一棟溫室澆五分鐘，到中期減少一半，後期就只要三十秒，「因為葉片長大，遮住土壤，曬不到太陽，泥土是潮濕的，不需太多水。」
