This research aimed to find out the possibility of the growing material development: bagasse, sawdust and eggshell. For studying both physical and chemical properties, the proportions were divided into four methods by weight (bagasse : sawdust : eggshell) 1) 75:75:0, 2) 75:75:15, 3) 75:75:30 and 4) 75:75:45, and the controlled quantity of starch paste was used as a binder. The results found that all proportions were able to form growing media. The 3^th proportion was the most appropriate for the growing material development. Its physical properties were a moderately smooth texture with a good adhesion, the average water absorption at 38.92% and the average slake at 2.77%. For chemical properties, the results found that the pH (potential of Hydrogen) at 6.02 and the electrical conductivity (EC) at 3.58 dS/m, which showed the salinity of the growing material that possibly affect sensitive plants. Furthermore, adding more eggshell, the water absorption and electrical conductivity (EC) also increased.
