Growing mushrooms is the easiest thing on the earth bro all you need is spores and soil , by my experience you put spores in water wait till it make it self like blob in water (i know it sounds funny XD) . Next step you need to put soil in the box that you can close you spray it with water with spores then you close it and put to dark place then you wait from time to time spray it with fresh water . Then you cut it but always leave some of the shroom in the ground cuz it will reproduce again and again .Next step is my favourite drying the material you can find many videos on clear net how to do it .
I hope it helped :p
