High Tech Mushroom Grow Guide

This guide is intended for people who have the ability to steam their mushroom bags in a boiling water bath or large pressure cooker for a number of hours in order to kill the pathogens and competitors inside the substrate. 

Before embarking on this project we recommend trying the low tech method explained in this guide HERE which greatly reduces the need for the specialty equipment used in this more high tech method.

Having the equipment to steam or boil the mushroom bags in a safe controlled manner greatly increases your ability to grow many more species of mushroom than you are able to with the low tech method which is usually used for varieties of Oyster mushroom and now also for Shiitake mushrooms.

For this grow guide the equipment needed is slightly more complex however a large pressure cooker pot is big enough to suffice for a small scale operation.
