After careful preparation of the compost and/or sterilization, sow the spores. Depending on which variety you have chosen, place the spores at a certain depth. You can refer to the kit for the preferable depth; the best way is to keep the kit with you while proceeding.
Within 6-8 weeks after sowing, some of the mushrooms will mature. Harvest only the fully developed ones. You can pick further crops after every week. The ones that are harvested after the first crop are called flushes. When you have finished harvesting from the jar (after about a month), discard the jar and start again.
Sterilizing Without a Pressure Cooker
As we have seen already, a pressure cooker is used for the sterilization process. So, if you have a fair idea about other options for sterilization, then you can successfully grow shrooms without a pressure cooker. The ideal method is steaming. A large cooking pot having a correct-sized lid that can hold the jars, is required for steam sterilization.
Add water (not much) to the pot and keep a steel utensil (upside down) at the bottom. Place the jars over the utensil, so water from the pot does not enter the jar. For proper steam sterilization, allow water to boil for an hour and cool it. You can inoculate the spores when temperature in the jar is 90°F.
If you want to grow shrooms without spores, the answer is by using mycelia or by tissue culture method. For growing with mycelia, you can follow the procedure given here. Tissue culture method is usually done in well maintained laboratories under controlled conditions of light, temperature, and humidity. Therefore, the former method is more practical.
