Grey oyster mushroom cultivation in Malaysia have been well known for years due to its beneficial properties in both gastronomy and medicinal sectors. Although this economic sector is popular among all soil of people, there's still problem that risen from this industry. Spawn production have been a growing continuous problem in grey oyster mushroom cultivation across Malaysia. Finding local growers that are able to produce grey mushroom spawn in a big scale might may be a slight problem for oyster mushroom producers as not many oyster spawn producers can be found. Due to lack of specific ways to produce spawn, spawn production activity is still at the low rate although grains need can be find locally. This research project mainly will be done to identify alternative grains that can be find locally for spawn production. There will be various local found grains which varies in size that will be used such as corn, millet, popcorn, soy bean and barley. 200 g of corn and millet grain was put into the big jar while 150 g of soybean, popcorn and barley grain will be put into the small jar. Each jar will have two replications. For the grey oyster mushroom spawn production, potato dextrose agar (PDA) will be use as media to culture the spore of the grey oyster mushroom. Then, the media that full of spawn will be put into jars containing various grains to ramify. Key of this experiment is the find which grains work excellent for grey oyster mushroom spawn growth. From this experiment, corn grain shows better weight of mycelia ramification and spawn productivity for grey oyster mushroom with both replications of mean of two variables were 9.83 and 4.95 while both replication of millet shows 8.00 and 196 mean. For small jar, both replication of barley shows 18.9 and 12,7 for both variable. Both replication of popcorn shows 14.1 and 9.4 mean while both replication of soybean shows 11.2 and 7.5 means. Between all types of grains, only corn grain shows significant difference with (p<0.05).
