RastaKaze, I'm a bit confused. You said you can do outdoors with woodchips right? But then you're talking about keeping equipment sterile and stuff.

Does the outdoor woodchip method work?

This is from the site link you gave:

Effects
Produces 2-3 flushes of mushrooms every season and the harvest increases year after year!

Usage
Buy a bag of woodchips and choose a shady spot in your garden, mix the spawn bag with the chips and keep them wet! Is that simple or what?
