I'm going to revive this thread an ask what humidity every likes to have in their kiln during the 4-6 weeks of kilning?
I'm actually headed this week to pick up supplies for building it. I've already got an Arduino, and I have some basic programming experience. I'm going to purchase relays to control the 2QT crock pot that my wife gave to me (missing a leg and its chipped on the rim but works great still). Still need some fans. The kiln will be in a garage (same place I'm going to air cure the tobacco).
