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.
I use a seedling starter mat. I tend to brew when it’s cold enough that I sort of don’t need the fridge (but it would help) and it keeps it about 3-4°C above ambient no problem, even after fermentation.
