PURPOSE: To provide a prefabricated water-feeding culturing tool enabling the growth and appreciation of various kinds of horticultural plants by preparing a detachable vessel having a vertically connecting gap between the inside of a circumferential frame part and a bottom plate part and stacking a plurality of the detachable vessels in vertical direction.

CONSTITUTION: A plurality of detachable vessels 1 each having a gap 15 between the inside of a circumferential frame part 13 and a bottom plate part 14, a detachable storage tank 16 attached to the reverse surface of the bottom plate part and a water-feeding cylinder 17 vertically connected to the vessel are connected with each other through fixing parts 12. Water or a culture solution (w) is dropped downward through the gap to prevent the overhumid state and facilitate the flow of air into the vessel.
