Bonus feature of this dehydrator, it acts as an incubator for sourdough starter. 
Discussion
I have an old Excalibur dehydrator I use to help rise the dough. It really helps in the winter
What is the lowest temp setting?
95 F which is a bit too hot so I don’t keep it on for longer than 10 hours at a time. Then I let it sit at room temperature (which right now is 68 F) for another day.
LFG!!!
Could use it as a filament dryer too, I bet
I too, watch my sourdough starter with knuckledusters worth of accoutrement.
