Im with dasprout, get a good indoor system with sterile bag and grain if u wanna do spores. Works very nice, my fav golden teacher was done that way.
Over here in spain u get people who sell coloniZed substrate in a tupperware, all u have to do is give a little light (for the shroom to "know" its above ground) and the right temp, humidity and u atart getting pins. U can also cut up the colonized subtrate and give it some more food (ex floor and a bit wet vermiculite or even hay) and let it recolonize before you set it up for fruiting.
Growing mushrooms is nothing like mj, get reading a bit before you start. Basicly 2 cycles, under ground in the dark, mycelium and once its taken hold of ur substrate fruiting/flowering in light
