Lesson 3: BULK SUBSTRATE, CREATING THE MONOTUB

You will learn what is a bulk substrate, & how to create the mono-tub

A bulk substrate is a material used as a growing medium for cultivating fungi, particularly mushrooms. It typically consists of organic materials such as straw, sawdust, wood chips, or a combination of these. The primary purpose of a bulk substrate is to provide the necessary nutrients and environment for mushroom mycelium to colonize and fruit. By using a bulk substrate, cultivators can produce larger quantities of mushrooms compared to other methods, as it allows for better moisture retention and nutrient availability.

A monotub, short for "monotub fruiting chamber," is a type of containment system used in mushroom cultivation. It is typically a modified plastic storage bin that creates an ideal environment for fruiting mushrooms. Monotubs are designed to maintain humidity and provide adequate air exchange, essential for the development of healthy mushroom crops. By combining a bulk substrate with a monotub, cultivators can efficiently manage the growing conditions, leading to successful mushroom production. This method is popular among both beginners and experienced growers due to its simplicity and effectiveness.
