I can vouch for this. I recently had a wonderful experience spanning a few months cultivating Psylocybe cubensis by salvaging spores from a bag of dried shrooms (spore prints are as illegal as the shrooms themselves here and really hard to come by). Coming from a physics background and never really having done work on living things it was almost magical watching the spores germinate on agar plates, transfering healthy mycelium away from contamination onto new clean plates, colonizing grain with the resulting mycelium and in the end fruiting several healthy flushes in a small plastic container in my cupboard. You really just need a kitchen and some commonly available groceries. I'm now cloning store-bought edible mushrooms and planning to grow enough for my own dinners throughout the warmer season. It's a very rewarding hobby.
