Coco powder was capable of holding water in quantity and time. Pore structure with high catch and hold water. Will fit the decorative medium caladium damp. Moreover, coir dus-other-name easy to obtain and relatively cheap.

Generally, the degree of acidity of coir dust close to 6, while the medium caladium grow well at pH between 6.5 to 6.8 was.
