The hydroponic flower root system is soaked in the nutrient solution, and the buffer capacity of the nutrient solution is worse than that of the substrate. Due to plant metabolism, new roots continue to grow and old roots continue to die, while the rotting roots soaked in water produce and secrete toxic substances, it is disadvantageous to the growth and development of the root system. In addition, because different flowers have different absorption of nutrients, it is selective, so it often causes nutrient imbalance in the nutrient solution. Sometimes physiological diseases are caused by element deficiency, and the imbalance is also caused by the effect of temperature on PH, especially in hydroponics, which is due to the poor buffering capacity of plant roots immersed in water. Therefore, hydroponics should be changed regularly. The liquid was changed once a month in winter, spring, autumn and each season, and once every half a month in summer.
