Do you have a "thermostat" on that fogger? If you have a sensor that measures humidity and turns on the fogger automatically you should probably be ok, but you dont ever want alot of condensation to be in the cage. Some condensation on the sides is ok, but water on the floor, or inside his hide should not be there. Too high of humidity can easily cause an RI, or scale rot. Personally I just mist my Snakes every other day. this keeps the humidity in 50% to 70%. I keep it closer to 50% when not in shed, and closer to 70% when in shed.
