Abstract: Gracilaria is one type of seaweed producing agar (agarofit) that many found in Indonesian waters. In order to contain gelatin-based hydrocolide compounds commonly used as thickening agents in the food industry. Differences in early biomass and spacing significantly affect the growth of seaweed. This is very related to the competition of each individual seaweed in getting nutrients as food. The success of the planting system is influenced by the use of good seeds and the appropriate weight will increase the growth. This study aims to determine the effect of seed weight and spacing on the growth of seaweed Gracilaria verrucosa by using the method of vertical rope. The experimental design used was Factorial Design, where factor A (weight of seed 50 g, 100 g, and 150 g) and factor B (spacing of 20 cm, 30 cm and 40 cm). The observed variable is the specific growth rate. The result of variety analysis showed that the difference of seed weight and spacing significantly influenced (P <0.01) on G. verrucosa growth. Based on the results of research, the highest specific growth was found on seed weight factor of 50 g, ie 5.4% / day and 30 cm plant spacing factor of 4.2% / day.
