hahaha...misinformation alert.
growing mushrooms outdoors takes months, and fruiting occurs maybe 3 months after you "innoculate" anything. Depending on the species, you must coincide with climates and such. In other words, not all species can be grown in the same environment. If you want magics, try P. Azurensis; they fruit in near-0 temperatures, and are great for more northern climates in the fall.
You first need spores, live culture or similar of the species you want, that is already colonized a substrate. For an outdoor patch you need alot of substrate, atleast 4ftx4ft for a nice healthy patch. This takes time, and is usually stalled by contaminations. All of this occurs before you get outside.
I'd recommend trying some edible species before you try the magics, to get a feel for the dynamics of mushroom biology. It is simple in theory, and can be very simple in practice if you reserach and get a method going first.
But you do not get mushrooms in 3 days. I wish. Sporeworks is okay, there are better suppliers however. PM me if you want more information.
