Take good quality of wheat straw. Soak for 16-18 hours then drain out excess water. Mix 5% wheat bran (w/w). Fill 2kg substrate in each polypropylene bag and autoclave at 22 lbs pressure for 1-1.5hr. On cooling spawn the substrate @ 2% and incubate at 25-26oC for spawn run for 20-25 days. On completion of spawn run give cross cut to give slits and hang the bags for fruiting at 25-26oC. Spray water twice on bags and maintain high relative humidity (85-90%) by spraying water in the room. Give 1-2 hrs. diffused light and aeration also. Fruit bodies will emerge in 10-12 days will mature for harvesting in the next 4-5 days. One can harvest 1.0-1.4 kg fresh mushroom per kg dry straw in 3-4 flushes. Mushrooms can be sun-dried.
