Hydroponic system nutrient solution sequencing
The aim of this study was to understand differences in microbial communities caused by the type of hydroponic system. Bok choy was grown in five different hydroponic systems, and the nutrient solution was collected weekly for sampling of the v4 region. The five hydroponic systems were the deep-water culture, Kratky, ebb and flow, drip irrigation, and nutrient film technique.
