This experiment was carried out investigation of optimum concentration of supply nutrient solution in hydroponics of sweet pepper using coir substrates (coconut dust fiber=70% : 30%, v/v). During the growing period, it was found out that the electric conductivity (EC) would increase in proportion to the supply nutrient concentration but it was in inverse proportion to the moisture content. The pH of drainage was stable, while EC was high showing EC $7.3;dS{cdot}m^{-1}$ in EC $4.0;dS{cdot}m^{-1}$ of supply nutrient concentration. Also, standard deviation and coefficient of variation were high. Plant length was no difference by the supply nutrient concentration. Photosynthesis rate was generally high in supply nutrient concentration EC$4.0;dS{cdot}m^{-1}$. Fruit weight was heavy in supply nutrient concentration EC $4.0;dS{cdot}m^{-1}$, fruit shape was close to a regular square in supply nutrient concentration EC $3.5dS{cdot}m^{-1}$.
