This study is trying to apply soilless medium film culture in an auto-production system by using 'San-Feng' pak-choi (Brassica campestris L. Chinensis Group). Hopefully, to reduce the production cost by using automized and factorilize management, to produce clean and healthy vegetables for customer use, and to increase agribusiness competences in the global world eventially.
In soilless material thicknes, using 1.0, 2.0, and 3.0 cm of commercial medium. Florafleur-001H to produce pak-choi. As the medium thickness decreased, medium electrical conductivity (EC) incresed. Plant height, leaf number, leaf size, and dry weight were inhibited significantly. The best cultivation performance of was on 3 cm medium thick. However, the air filled porosity (AFP) of one to three cm medius thick was only 10.0％, 12.4％ and 14.9％, respectively. This caused great inconvenience in cultivation management. If rice hull (RH) and perlite (PR) were added to increase AFP TO 7.7-21.9％ as the commercial medium, leaf growth, fresh weight, dry weight, and final yield increased.
