Abstract: A bottom watering-type cultivation device which supplies water from a refillable water vessel (20) provided at a lower portion of a flowerpot (1) to a plant in the flowerpot (1). The bottom watering-type plant cultivation device includes a flowerpot (1) having a bottom part projected upward at a predetermined section thereof to a predetermined height to define a nutrient solution feed space (3) under the bottom part of the flowerpot (1), a refillable water vessel (20) to contain a predetermined amount of water therein to supply the water into the flowerpot, a nutrient solution guide (30) removably installed in the nutrient solution feed space (3) of the flowerpot (1), a water absorbing unit (24) engaging with the nutrient solution guide (30), and a root intercept unit (12) to prevent roots of the plant from infiltrating into the nutrient solution feed space (3).

Abstract: The present invention provides an apparatus and method of cultivating a plant using a subirrigating method. The apparatus includes a culture medium cell constructed in such a manner that artificial culture medium is packed in a packing material having excellent ventilation and moisture absorptivity to be shaped in a predetermined form, a planting pot which contains the culture medium cell and has holes through which a sufficient amount of nutritive solution and air pass, a cooling/heating device set in the lower portion of the culture medium cell to cool or heat the root of the plant, and a nutritive solution supplying device for automatically supplying the nutritive solution to a plant planted in the culture medium cell placed a distance from one or more nutritive solution containers, thereby supplying the nutritive solution and air to the root of the plant continuously to maintain the optimum growth environment, forcing the plant growth.
