How To Make The Easiest Mushroom Fruiting Chamber: Easy Mushroom Growing 

In this video we make the classic 'shotgun terrarium". So called, because it's covered in holes.
I have used this chamber to great effect and have enjoyed much success with it.
It's a simple chamber, consisting of a clear plastic tub with holes drilled in to the bottom, the lid & sides and filled with a layer of saturated perlite.
The theory goes that as the cakes warm through metabolic activity they raise the ambient temperature inside the chamber which then draws in cool air from the bottom through the holes. This air is humidified by the perlite as it rises, displacing carbon dioxide as it does so!
Quite a clever little design that absolutely works!
