Bucket Oyster Mushrooms: Grow and sell oyster mushrooms from straw in a 5-gallon bucket · Alt Ordo Systems Guide

Oyster mushrooms are the easiest gourmet mushroom to grow. They need no soil and no direct sun, and they eat wheat straw that farmers sell by the bale. You knock back the straw's own molds with hot water or a lime bath, mix in spawn, pack it into a drilled 5-gallon bucket and wait about three weeks in the dark. Then fresh air, light and humidity make clusters push out of every hole within ten days. A few buckets feed a household. A bucket filled every few days feeds a farmers market stall or a restaurant, because fresh oysters keep only about a week and chefs prize a grower who lives nearby.

This guide helps you pasteurize straw with hot water or cold lime, fill and fruit 5-gallon buckets, harvest several flushes, and sell oyster mushrooms legally to neighbors, markets and chefs.
