To develop suitable alternative substrates in hydroponics of sweet pepper, changes of water contents of substrates and electric conductivity (EC) of drainage nutrient solution, growth and fruit characteristics according to the kind of coir substrates were investigated compared with rockwool. In all coir substrates compared with rockwool during growing period, water contents were higher, EC of drainage nutrient solution except for fiber 50% were lower, and the coefficient of variation were a little, especially were so in fiber 30% of coir substrates. Plant growth in fiber 30% substrate was better than others but there was no significant difference. Photosynthesis rate and chlorophyll content were best in fiber 50% substrate. Fruit weight was no significant difference, but LID ratio and shape of the fruits were good in fiber 50% substrate and rockwool as which were close to regular square. Therefore, it was estimated that mixed coir substrates with fiber $30{sim}50%$ are enough in possibility as alternative substrate.
