zwyatt said:I still think moving the water dish closer to the heat in combination with those 4 small air holes could be contributing to the spike in humidity. Is there a reason that there are so few air holes? My 12qt tubs all have at least 50 or more 1/8" holes and some of them have humidity around 60%.
