    The plastic cover over the speed rack still allows air to enter the bottom of the chamber, which makes it possible for the fermentation to take place.

    Loading the sheets on the rack is important because there must be enough room for all of the pieces necessary for fermentation.

For this fermentation chamber, you'll need:

A speed rack:

The bones of your chamber. Speed racks are used in restaurants to hold trays of ingredients or food coming out of the oven. They're made of lightweight but sturdy aluminum and are equipped with rails onto which you slide sheet pans or gastro/hotel pans. They come in varying heights, ranging from 1 to 1.75 meters. Look for one that comes with a heavy plastic
or vinyl cover with zippers running up two sides. The cover will retain heat and humidity, and the zippers allow easy access to the interior. You'll also need a few sheet pans that are the correct size for the rack; the style and quantity will depend on which ferments you choose to make.

A small space heater:

The kind you might use to keep your feet warm underneath your desk. If the heater is equipped with a fan, all the better; if not, buy a small simple fan.

A temperature controller, such as a PID (proportional-integral-derivative) or thermostat:

This will adjust the temperature of the chamber as it varies according to external influences. You want a prewired version that you can plug a heater directly into. It's a specialized bit of gear, but it's not complicated or expensive. It will include a probe that you set either in the chamber to measure interior temperature, or into the ferment itself, such as when you're making koji.

A small humidifier (only when making koji):

The type you'd put in a child's room to help with a stuffy nose. Plus, a simple hygrometer to gauge humidity; it will look a bit like an oven thermometer. Or use a humidistat, which functions much like a thermostat. While slightly more expensive, it will simplify things by regulating the humidity in the chamber for you.

For a cheap rack and cover, I was very pleased to find the Hyllis from IKEA (|us|unbxdsuggestion|201811132211556208_1)
