DEVICE AND METHOD FOR HYDROPONICS

摘要

A device for hydroponics with which a plant (100) having a major-root portion (102) and a secondary-root portion (103) is grown and which is equipped with a plant support (2) for supporting the plant (100), a major-root irrigation part (3) for spraying a liquid on the major-root portion (102), a nutrient irrigation solution (10) in which the secondary-root portion (103) is soaked, and a liquid-fertilizer-concentration regulation sensor (5) which measures the concentration of the nutrient irrigation solution (10), wherein the measured concentration is referred to, thereby controlling the concentration of the liquid to be sprayed by the major-root irrigation part (3) and/or the concentration of the nutrient irrigation solution (10) in which the secondary-root portion (103) is being soaked.
