Second hand fridge with an inkbird thermostat.
I don't have a heater in there, but from my brews before the fridge the problem was keeping it cool, not warm. Does anybody with more experience than me have thoughts on why I might need a heater?
Looking forward to trying this out in a few weeks.
For he insulation layer, I've seen people use sponges. Do you recommend anything else?
No i use that too, works well and it's cheap.
