Control Hydroponics Cabinets with Artificial Light and Nanobubble Technology

Abstract

This paper purposes the design and construction of the plant controlled hydroponics and artificial light with nano bubbles to be used for growing vegetables hydroponics indoors. Using artificial light bulbs for vegetables with the appropriate intensity of light for growing vegetables, 1100 to 2000 lux, have proper control of the air inside the cabinet and use the nano bubble generator for nutrient solutions. In order to help nutrient uptake, contribute to the transport of nutrients from the root causes the plants to grow well. Two types of red oak salad were studied, including Dynamic Root Floating Technique (DRFT) system and still water system. The results found that the average EC in the DRFT system is 0.14 mS / cm higher than the stationary water system, pH of the DRFT system is lower than 0.3 and average of DO is lower than 0.61 mg/l compared with stationary water system. Considering the growth value of salads, it was found that the average height of the salads grown in the stationary water system was higher than DRFT system the 0.6 cm., the average bush width of the lettuce grown in stagnant water systems was larger than DRFT system 1.5 cm and root length of the vegetables grown in a stationary water system have a longer root length than the DRFT system 0.5 cm. The growth of red oak salad at 11 days in stagnant water system was significantly better than the 14.6% deep aquifer, which was slightly different, and both systems maintained their quality. Plant nutrient solution that affects the growth well. Therefore, it can be concluded that the proposed research can be used to grow hydroponics vegetables. It is very effective in both deep hydroponic systems and in stationary hydroponics.
