    A well-known planting medium in soilless culture is a coconut based material famously known in Malaysia as cocopeat.
    It is a viable ecologically friendly peat soil substitute for containerized crop production. The multipurpose growing media
    had received much interest particularly in commercial applications. This study focused on the physical and hydraulic
    characteristics of cocopeat perlite mixture as a growing media in containerized plant production. Perlite was added to
    cocopeat at a ratio of 3 cocopeat: 1 perlite. Bulk density, particle density, porosity, particle size distribution, water holding
    capacity, wettability and hydraulic conductivity of the media were evaluated. About 82.93% of the total particles were
    in the range between 0.425 and 4 mm in diameter at a bulk density of 0.09 g/cm3
    . Total porosity (79%) and wettability
    improved with the incorporation of perlite to cocopeat. This study showed that water holding capacity was very high at
    912.54% whereas the saturated hydraulic conductivity was low at 0.1 cm/s. The results showed that adding perlite to
    cocopeat had improved the physical and hydraulic characteristics of the media.
