I got a Small 130l Box Freezer, replaced the thermostat with that of a stove(3-40 Celcius)
& Atached a 100w lightbulb. Takes about 5 min to regulate the right temp. This keeps the temp 100% constant for ever.
I use another boxz freezer for the cheese cave. I replaced the thermostat with that of a double door fridge, but it still got too cold. Then I plugged it to a timer switch that switches on 15min every 5 hours. That keeps it at 12 degrees celcius. I am wondering though if the water that creates inside the freezer & melts is going to create a problem? Any thoughts? It's not alot, but it's there.
