Psilocybe azurescens is probably the most potent psilocybin producing species on earth. Spawn can be grown on rye or birdseed and transferred to sterilised woodchips. Room temperature is fine for growing out spawn. This fully colonised woodchip spawn can be used to inoculate woodchips in outdoor beds.
Another option is to use grain spawn to inoculate soaked cardboard. Soaked cardboard is a highly selective substrate which can be used without sterilisation or pasteurisation. When the cardboard is colonised it can also be used to inoculate outdoor beds. More colonised cardboard or woodchip spawn results in faster colonisation of the chips in the outdoor bed and increases the chance of success.
As a substrate for the outdoor beds freshly chipped wood and branches can be used. If pre-packaged wood chips are used it might be necessary to soak them in water for a couple of days before using them. The beds should be made in a shaded place and can be covered with a thin layer of casing soil. Grass planted on top of it helps to keep the moisture content high.
Beds should start to fruit in the Fall and at that time extra watering might be necessary to keep the moisture content of the bed high. The bed should never be allowed to dry out.
