Hydroponic Culture of Fast Plants in Nutrient Conditions Lacking Macro-and Micronutrient Elements by Using the "Aiterrarium" via the Internet

Abstract

The purpose of this research is to verify hydroponic culture test under nutrient deficiency of Fast plants (Brassica rapa) to make students unde rstand nutrient necessa ry for plants, and whether experiment using "Aiterrarium" can be executed at upper secondary school. The remotely-controlled Aiterrarium is an indoor gardening system in which the fluorescent lighting, temperature, humidity, soil water content, and water supply is all controlled via the internet. The attached web camera can monitor the growing process from anywhere via the internet. As a result of practice in upper secondary school, the students were able to visually observe the nutrient deficiency disease, and understand that the nourishment necessary for the plant was the inorganic salt dissolved in water. It is necessary for the plant as nourishment during the weekend and summer vacation, etc., it is very effective as the equipment that can support long-term cultivation of the plant, and can expect the effect as one way that expands the possibility of the study support and a new learning system, since Aiterrarium allows us to freely control not only inspection and the preservation of a real-time image, but also sprinkling water and the temperature management, etc.
