PROBLEM TO BE SOLVED: To solve problems that, though there are various hydroponic culture systems, urethanes, rock wool, granular cotton or the likes are used as supporting bodies and media for growing plants, but they are expensive and need cost to treat them compared with the soil. SOLUTION: This hydroponic culture system is brought to avoid an accepted theory that a hydroponic culture equals to non-soil and use an eclectic plan style in which a nutritious liquid and a usual soil are used, that is, urethanes, rock wool, granular cotton or the likes are not used as a supporting material and a medium. Head formation of vegetables with formed head becomes better than that of water cultured ones, owing to a larger buffering capacity and an easy cultivation depending on the eclectic plan style. |
