PURPOSE:To obtain the subject case readily observable for a cultured state having excellent energy-saving effect with increased irradiating amount of light to plants by installing a light source for irradiating light in a room and providing a night cover of a heat radiation-reflecting film capable of winding on a glass window. CONSTITUTION:The objective growing case is obtained by installing plant- growing plates 5 made of a metal such as stainless steel, fluorescent tubes 10, a circulating pump 3 supplying a nourishing solution as a means of soil culture or water culture and a siphon 4 in a growing room 1 and providing a night cover 7 having a heat radiation-reflecting film 9 so as to be automatically recovered by a rotating drum 8 at an upper part on an outer side wall of a glass window 6 of the growing room. |
