Effect of Bubbling Jet on Growth of Root Vegetables in Indoor Hydroponics

Abstract

   In recent years, plant factories with indoor hydroponics come to attract attention with the development of low cost LED lamps. In addition, the fact of low food self-sufficiency rate in Japan makes it important to develop of plant cultivation technology for a stable food supply based on the engineering knowledge and conception. In this study, water remediation technologies utilizing the micro-bubbles and micro jet are applied to cultivate root vegetables in hydroponics. We aim to develop the automated indoor type of food production system with fully controlled environments. In this paper, we represent the results of the effect of dissolved oxygen on growth of root vegetables.
