I found sterilizing the jars (in a hot bath), innoculating the (brown rice) and getting the mycelium to take over took the most effort and time (takes like 2 months in the dark for the mycelium to take over the entire jar).

Getting it to fruit was easy and all I needed was some vermeculite to place the mycelium block on top of and a plastic container to act as a terrarium so it will trap the humidity from the spray bottle.
