Hello fermentors,
New here and thought I'd share my incubator setup. I found a thermostatic bar heater on Amazon, and purchased this along with a digital thermometer (to test how accurate the heater was, and monitor the temperature) and a wire rack to keep the tempeh of the heater. I then stuck all of this inside a soft insulated picnic hamper which we already had, and used some drinking glasses to balance the rack on.
I spent an evening fiddling around with the thermostat on the heater trying to find the perfect temperature, and discovered there is a large gap of around 17 degrees centigrade between the high temperature where it cuts out, and the low temperature when it starts up again. So it's not very precise! In the end I found a setting where the maximum temperature didn't go above 35degC and made a reference mark with a Sharpie so I could easily find the same setting every time.
Quick and fairly cheap setup (~£50), but does the job and makes great tempeh!
What's your setup?
Jamie
