Proofing pot (a prototype)!
I'm experimenting with a way to keep my starter at a suitable temperature when building it up and during bulk feeding. This is a prototype that I devised.
The temperature control device (thermostat) can be set to the desired temperature which is read by the probe and the heat lamp turns on and off accordingly. I have actually found a better one for this purpose which keeps the temperature within a range that you set and is five times cheaper, which I have ordered. The heat lamp is meant to be for lizard etc. enclosures.
One thing that could be immediately improved with the existing kit is to use a light bulb with a lower power rating. Mine is 100W which too much. I keep the pot partly covered with a towel and thus regulate the temperature inside the pot.
It's not as sophisticated or as versatile as a specially made proofing box, but it does work.
