The present invention relates to a device for calculating the weight and moisture content of a plant. More specifically, the purpose of the present invention is to accurately measure the weight of a medium used for nutrient solution cultivation, thereby accurately calculating the weight of a plant and the moisture content of a root portion of the plant. According to the present invention, the device for calculating the weight and moisture content of a plant includes a cultivating bed on which the medium is mounted, wherein nutrient solution is supplied to enable the plant to be grown, a weight measuring portion, and a control portion. The weight measuring portion is configured to measure the weight of the medium mounted on the cultivating bed by floating the cultivating bed in the air. The control portion is configured to collect a measurement value from the weight measuring portion, and calculate the weight and the water content of the plant by using the collected measurement value. 본 발명은 식물의 중량 및 함수량 산출 장치에 관한 것으로, 양액재배에 사용되는 배지의 무게를 정확히 측정하고, 이를 통하여 식물의 중량 및 식물의 근권부 함수량을 정확히 산출하기 위한 것이다. 본 발명에 따른 식물의 중량 및 함수량 산출 장치는 양액이 공급되어 식물이 생장하는 배지가 탑재되는 재배단, 중량 측정부 및 제어부를 포함한다. 중량 측정부는 재배단을 공중에 띄워 재배단에 탑재된 배지의 무게를 측정한다. 그리고 제어부는 중량 측정부로부터 측정값을 수집하고, 수집한 측정값을 이용하여 식물의 중량 및 함수량을 산출한다.
