When the liquid level in the mixing tank (C) reached a certain water level, preparation started, and the process ended after the stock solution and water were supplied in an appropriate amount. In this case, the above configuration does not have the precision to mix multiple raw solutions and raw water in the diluted nutrient solution preparation and supply stop means (mixing tank) C, and the mixing time becomes longer and extra equipment is required. requires
In addition, the amount of diluted nutrient solution created is not arbitrary, and there is a drawback that diluted nutrient solutions with different components, mixing ratios, and amounts cannot be created continuously.
