1. A plant cultivation apparatus comprising:
a cabinet having a cultivation room accommodating at least one bed and an open/close door for opening and closing an open front surface of the cultivation room, plants being cultivated in the cultivation room;
a water supply module provided in the cultivation room to supply feed water to the bed;
a lighting module to emit light toward an inside of the cultivation room;
a circulation fan assembly configured to circulate air in the cultivation room;
a temperature control module configured to adjust a temperature of the air circulating in the cultivation room; and
a controller configured to control at least one of the water supply module, the lighting module, the circulation fan assembly, or the temperature control module according to a cultivation stage and a type of the plant input through an input unit;
wherein the bed has a depression which is formed to be recessed from an inner bottom of the bed to receive and store the feed water from the water supply module,
wherein the bed is formed with a sensing protrusion which protrudes from a bottom surface of the depression, the sensing protrusion having an upper surface positioned higher than the bottom surface of the depression and lower than a bottom surface of the bed,
wherein a residual liquid detection sensor is disposed below the sensing protrusion and detects whether residual liquid on the sensing protrusion is present, and
wherein one among a standard cultivation mode, a power saving cultivation mode and a smart cultivation mode is input through the input unit, and when the smart cultivation mode is input, the cultivation stage and the type of the plant is further input through the input unit.
